Welcome to the home of the motorcycle fixer.
My plan is to help people learn how to fix and maintain their motorcycle. We're hopefully going to build a custom in the future too and work out some problems along the way.
I owned a motorbike shop for 10 years and in my day job I'm an engineer

5 years down the line mate youve given my er5 life this is my first project and without your video i mightve given up on it 😂thank you so much
Thank you You're very welcome 👍
Very nice to watvh you video👍 Just a silly question and i dont know if it is the same with the gs. But on my carb f650 from 99 there is a tiny horizontal hole in the head right next to the right spark plug. As i saw on some Fotos in the Internet it is normal and Stock, so the previous owner didnt do anything weird😂 But im very interested in the reason for the hole. Can you explain it to me or is it different with the head from the GS?
The reason for it is to make sure any water that gets into the spark plug hole can drain away Thanks for watching
@@motorcyclefixeroh that is cery interesting. I habe first panicted but was relieved as i saw, that it is by factory and now i know for what it was drilled. Thank you very much 4 your Quick answer👍
This was really helpful. Thankyou!
I'm glad it helped 👍
My tensioner is loose but my chain wont get as loose at yours and i cant time it what is going on its a oem chain
Hey I have a new hot cams timing chain with my new cams and it's very very hard to get onto the cams cuz it's so tight I understand what your going through I had to put my cams in a certain way it was hell idk if I have it timmed right I over tightend my cam caps so gotta order new ones 😭😭😭
Oh no 😪 Best of luck with it
Did you take the tensioner out completely Also check the bottom sprocket to make sure its on there properly
Greats from Amsterdam 👏👏
Thank you
Thanks!
Thank you very much Much appreciated
Hi, I have a Lifan 125. The kick starter keeps jamming. But when I take the spark plug out it kicks over ok. Any idea what causes this. Thanks.
Is the spark plug definitely the correct one If it's too long it will foul on the piston
i have some chinese 125cc pit bike... its started to make like a metal slapping sound when riding, in every gear , but it stops making the noise when the bike is in neutral or with the clutch pulled in. im assuming something in the gearbox is ratting around like a tooth broken off maybe? hopefully its something obvious like that.... it runs well and still shifts and rides fine just that noise of impending doom is forcing me to do something before its too late. ever had some mystery noises like that before only while in gear? as far as i can tell its not the primary chain but possibly could be the cam tension chain
It could be the timing chain tensioner i suppose What type of tensioner is on your engine It could be a few things i suppose. I would start to take it apart and see what you find
@@motorcyclefixer i have pulled the motor out planning to take it fully apart and look for anything wrong, but since the first step is to remove the timing chain and head i guess i should check the tension and see if its sloppy. i know i had this head off before buti can't remember how the tensioner works. theres bolts on the bottom but theyre all screwed in fully so there is no 'locknut' kind of adjustment from what i see. but i have no idea what im looking at since im new to this stuff. sorry for being vague but im wondering if you have any generic advice for me? i guess to start i should figure out what kind of motor im working on(aka which motor china cloned it from, if any) and find some documentation
thanks..but please why the second carburator (closer to fuel tap) has its vacuum hose not connected? according to manual it should be connected to the valve .. i dont get it :(
You only need one of the vacuum lines conected to the fuel tap
torque settings for filter housing?
I don't have the manual but m6 bolts into aluminium is normally 6-8Nm
@@motorcyclefixerthanks mate. And sorry to be a pain but for the love of God I can't find the size of the washer for the sump plug anywhere. Do you know the size?? I have new oil and an oil filter here waiting for the washer lol
Sorry i don't know off the top of my head I would drop the oil and then see what size they are Halfords or someone similar should have them on the shelf
@@motorcyclefixer thanks for replying mate
@@HellRyder18 no problem
Had my 125 KTM duke from new, and only driven 150 miles and the rear brake has the issue already. Is this normal for a new bike? Or should I take it back to the dealer? Wdyt? Thanks in advance.
I would take it back to the dealer and get them to make sure it's ok. And no it's not normal for it to go like that. They could have sheared a seal during assembly or something
@@motorcyclefixer thx. I pumped it a few times and took it out on a run to test, and it started working after a while. I will keep an eye on it.
Hi, my rear brake is firm now and not spongey at all, but it feels like it has no stopping power unless i push the brake all the way down and lock the wheel up. My rotor and brake pads are fine in diameter according to the manual and seem to be in fine condition. Any idea what could be the issue? Thank you! 🙏
it could be the brake linings. are they too hard or have they been contaminated with oil or grease. Are they wearing equally ? Is the brake carrier seized so its only braking on the piston side? Get the caliper off and inspect it
Still got no pressure , did everything in the video still got no pressure
It could be that you master cylinder seals have gone then
Thanks for the video. I’ve seen numerous descriptions of how to bleed the brakes, but this was the clearest and most concise. I’ve bled the rear brake on my 98 Bandit 600, and changed the pads, but still too much travel in the pedal. I’m going to try bleeding again, with this method, and hopefully fix the problem. Cheers!
Thank you. I hope you get it sorted
Hey i just brought a z155 What do you set the valve clearances to? And how many turns out on the fuel strew?
1 and a quarter turns out on the fuel screw to start I cant remember the valve clearances off the top of my head sorry. They'll come up on google though
hello mate i’m getting the same problem with the gears but also the kick start gos solid to, took the flywheel cover off got a socket on there and it freed itself it’s done it again but i pushed the bike and it freed itself up bit baffled to what it could be does it whist your kicking it running fine now but i would like to find out what could be causing the issue cheers
it could be a sticky valve but it also could be a number of other things. i would take it apart to see what's going on with it
Great vid, thanks!
Thank you
I damaged my first gear on my Wpb 190cc my chain come off and jammed around the front sprocket so my first gear is no longer working but im clueless about changing it 🥴
It couldbe a number of things to be honest. You need to take it apart until you find the problem
Hi! First of all, AMAZING VIDEO. Anyway, I bought a F650gs and the starter started spinning 'freely'. Ordered a new bendix gear and the assembly. Opened the side cover and my idle gear seems to be missing the axle, the sleeve and the washer! Is the axle something that just hammers on or do i have to open the other side of the engine up too? Couldnt figure that part out by watching this. Also, i havent been able to locate the part number for the axle. Any idea where i could source one?
Hi Thank you I'm glad you liked it Check out my other videos on this engine I'm sure i covered it in one of them. I cant be 100 % without watching the vids but i think that the shaft and the gear can be taken out seperately
In the uk i bought the parts for this engine from motorworks bmw
www.realoem.com/bmw/enUS/showparts?id=0172-EUR-01-2001-R13-BMW-F_650_GS_00_0172,0182_&diagId=12_1069 i think this is the diagram that shows the pin and gear assembly
@@motorcyclefixer found the sleeve and axle from a bike at local breakers. For the washer. Its available at BMW for order, but I just popped an axle shim that had the correct internal diameter and thickness there. Back up and running. Cheers!
Helped me cheers
I'm glad it helped 👍
my daughters bike rks 125 is overheating i would like to check the oil pump but i dont know how to get to it do you have any videos on that at all
Sorry I'm not sure on this engine how it works and i can't get an engine diagram from anywhere
Your video was informative. Thank you.
I'm glad you liked it 👍
What mm is the flywheel puller? I’ve ordered the wrong one 3x now. All too big…
Hi Sorry I'm not able to measure it at the moment I'll do it when i can but it may not be until next week
Hi Sorry but i would have to take the side cover off to check and the engine is up for sale at the moment so i don't want to take it off. I hope you have success with it though
What was the extra wire going to the rubber cap coming from the stator?
Its for a neutral swtch if you mean the green / red wire
When I kick start my engine it grinds and I need to push the kick start shaft in for it to stop grinding in neutral then when I switch gears it will come out slightly and grind again and will need to push in again for it to stop grinding shaft play is about 1/4” to maybe half inch of play
I would take it apart and look at it. It could be that the circlip has come off the kickstart allowing it to move or the idler gear is loose. Take the clutch over off and have a look
How much for a full rebuild on a 120 pitbike please buddy
is the engine complete or in bits do you have the bits you need replaced? what is wrong with it? It would be 90£ labour for just a standard rebuild
@@motorcyclefixer all together and I think i do
Itll be around 90£ then Email me on [email protected] if you want
I got another one that I think need a new gear box
ok i can have a look at both if you want
Hi my P. bike it keeps on shutting down like it has no fuel or spark when you fuel direct in the spark hole it will start after finishing it will stop .. I changed a carburetor. Ignition coil.plug. and stater coil
It could be a number of things really. Is the timing correct. Do you have compression. When did it start happening?
@@motorcyclefixer I don't have the tester .any other way I changed almost everything to new maybe it's be causes.
Good job. Thank you.
Thank you for comment 😀
Thanks but you didn't say what a bleeder is and where to get one or attach it. I'm a super newbie
Hi Rachel If you google 'brake caliper bleed screw' it will show you examples of it. It's a bolt with a hole in it that is always near the top of your brake caliper. i just put a pipe from it into a container to catch the fluid.
Fix my bike please mate
Hi Connor What bike is it, What's wrong with it? can you get it to me?
My clutch basket isn’t spinning and it’s in neutral, any idea?
with the engine running or not? have you stripped it down or has it just started doing it? take it apart and see if the gear on the back has become detached from the basket.
@@motorcyclefixer managed to do that and change the clutch gear as teeth were missing but when I try kick it over it seems to sometimes get locked up ?
there could be bent teeth on the crank gear if you didn't change that as well
@@motorcyclefixer on the actual clutch basket with all of those teeth there are 2 teeth missing, could it be that?
@@ts7yt yes plus there may be bent teeth on the gear that connects to it on the crank
Great video pal thanks
I'm glad you liked it 👍
thank you
😍😍 thanks
I'm glad it helped 👍
What is the small circle thing with 5 magnets and 4 cords just up and right of stator , i bought a bike but the cords were cut . Is that an electric start ?
It's a gear indicator switch. If you have a display on your bike that tells you which gear your in then this is what controls it.
I gave up on my 426 and hired a pro 😂
Sometimes its better to ask for help 👍
I have a yx 150 that cant find neutral. I have N bottom then 4 clicks up, and even after replacing the clutch hub gear that I found was initial culprit, when I was told motor was blown I'm still stumped, back tire still spins and clutch wont disengage gears or stop back tire from spinning.
If you turn the bike off and put it in neutral, try then to turn the back wheel. Is this turning the engine over or can it spin without moving the piston?
hello mate, i'v taken the air box off my er5 and replaced it with cone filters on the carb and i don't know what to do with the breather pipes. any idea . it's going to be a cafe racer. cheers. good vid by the way.
Thank you The breathers can just be run to air, usually to below the engine A lot of people put a fuel filter on the ends to catch the oil mist
dont suppose your in the swansea area bro?
I'm in tredegar
ps...subscribed boyo
Thank you very much
big help thankyou brother.. ill try all that tomorrow. God bless ya from wet and windy south wales
I'm in tredegar
Mine struggles when I drive in rain
Try changing the plug lead and cap.
I have a question! If both marks line up for the timing , can it still be out if someone hasn’t put it together properly?
Not if the woodruff key is in place on the crank and everything lines up You can check the mark is correct on the flywheel by checking the piston is at TDC with an allen key down the plughole
Do you know what the small clear cup with the black cap on the top is called? It is on the side of the bike and has a black pipe coming out of the bottom.
Sorry i don't know what you mean. What is the end connected to on the engine.? Is a a crank case breather? Carb overflow ?
That's likely to be the brake fluid reservoir.
Brooo my flywheel was rusted out I had another engine so tried to put that engines flywheel and stator on mine but the lil pin to aim you flywheel like the crankshaft lil pin it broke off so now the flywheel is on but the crankshaft is moving but the flywheel isn’t help me out.
The "pin" on the crank is called a woodruff key . You can replace them Measure the width of the slot on the crank and buy the right size to fit it. Sometimes you have to file down the key to have it fit perfectly but they may sell the exact size on ebay
@@motorcyclefixer thanks I thought I was going to have to replace the whole crankshaft lmao
@@motorcyclefixer you got a sub
Wow, how well explained everything! In my case, my first gear jumps to neutral if I don't have it pressed. What do you think is the problem? Maybe is it possible to solve it by changing the spring? Thank you for your time, you have earned a subscriber
Thank you very much It could be that the spring tension isn't enough Have you checked the groove that the detent wheel sits in If the groove is worn the wheel may not sit in it correctly
@@motorcyclefixer I'll check it! I haven't opened it yet
the stator plate on my 110cc pitbike only has one coil pack instead of two coils on his pitbike statorplate.is it unusual to have one coil pack?.there is a space for another coil pack with screws on it so if you want to add another coilpack. dosnt look like it broke off .the 2 screws are still on the plate .should u have to give the flywheel a wack with a club hammer or should it push on easy because on my 125cc pitbike i wacked the flywheel few time with a club hammer not too hard so not to damage anything. the flywheel didnt push on much and the notch thing on the flywheel is still 3 quarters off in line of the pickup point on the stator plate even after i put 2 washers behind the 2 screws on the pickup point so that the magnet on the pickup point is pushed outwards a bit more.
The stator plate with two coils is for the pitbike with a battery and lights etc. You shouldn't pack out the pick up There is a set distance between the pickup and the lug . 0.2mm
Can you help me with something please I was out riding dumped the clutch and my chain got wrapped around my sprocket my front one and has locked my bike up what do I replace
You'll need to take it apart to have a look I'd start by having a look at the stator plate and the cover to see if something is jammed against the flywheel
Morning sir, I have yz426 but the block is damage,it is pit sir the block of wr450 to 426 celinder head ,,wr is 4 stad bolt and the 426 is 6 atad bolt.
If it's a WR then it would be a 2 stroke Do you mean WRF 450 ?
Morning sir,,can I ask sir that block of wr450 ,it is pit to Yamaha 426 and the head of 426 is still remain?
i don't know sorry. there are many things that can affect this. diameter of the bore. stroke of the piston. configuration of the bolts etc. etc. without having them side by side and measuring everything i would say probably not
