Nice like to see torque specs and if it needed to be locked up when tightening the sprocket so that the rotation wasn’t going backwards?

Ive watched this video about 10 times a day over the last week prepping for some top end work needed on mine. One thing I may have missed but on the new head did you have to do anything to the cam to adjust the timing? Thanks again for a great vid!

It’s been a while since I’ve done one, I usually check to see what position they are facing before I disassemble, but I believe the cam lobes should be facing down toward the piston when setting up the timing

Did u have oil leaking into exhaust ? Was that the reason of getting a new top end? That’s my issue on my sons atv smokes and took off exhaust from head and a few drops of oil came out

im not really familiar with this motors , but i presume its like a lifan right? you should most definetly at some point do a 53mm piston on one of these things , they come stock at 52,4 (at least the lifans do) and you would think that ,06 is like nothing , but flat pistons do really suck , thats why they feel slow from factory , even the 125's . Oh and it wont cost you anything , these kits are like 50 bucks for the bore up , and you can get away with using same head , also there are the big head caps and the small ones ( i dont know how they called ,hope it makes sense) big head caps (the one that covers the timing sprocket in it) means that you can also use a stage1/2/3/4/5 camshaft

@@KGRowlo they are kinda tricky motors and supposedly "weaker" from the 110 wich poroved itself bulletproof , the 125 can get biger cam (certainly) , i think that the 125 has 14mm piston pin , i made one back in the day but the strugle was real cause i couldnt fing big bore ups from a well know make i soon found out that the yamaha t135 pistons have 14mm pins so i went to the machine shop with a brand new piston (62mm)and the stock cylinder and made it work(used cnc flange to lower compression) . however the small crank is not known to hold big power and i f'ed it , the rod almost killed me LOL it went straight out of the casing , while disassembling it i found 2 crank pieces instead of 1 .Looking forward to the vids

Sounds like it

2018 DB-34. Curious as to why I have an issue in top-end. Bike sounds like it's bogging at top-end, yet this thing fires up one kick, damn near every single time. I have changed my Main Jets all the way from 92 to 140, every size in between, and have never been able to get it tuned to a point where it won't bog down on top-end. I have even adjusted needle both directions, checked spark plug. Any idea what is cause the bog at Top-End. Also checked Valve Clearance. Tried without Air-Filter off as well. Any idea, anyone, what my issue is. Nibbi 19 Carb.

@@KGRowlo I think my pilot is at like a 32, it fires up amazing and idles great, hence why I never tried smaller. I think I will go that route, till I get correct Mikuni.

Great video. I did this on my kids quad because of low compression (70psi). Leak down test, heard air in crankcase. Did piston/rings/gaskets (cylinder still has cross hatching and not gouged). Did compression test, still 70psi and still leaking air into crankcase. Ever had this issue or any ideas on what to look for? Thanks
