Exactly right! I never did like the disconnect with cv carbs in many of my bikes. My 88 superglide back in 2000 was upgraded with the mik 42 along with pipes air filter and hot coil. Instant throttle response loved it. You can almost feel every power pulse of the engine. A friend has the bike now and his brother with a newer fuel injected Harley tried it out not expecting much with the old technology bike. He was speechless afterwards.

Thank you for this clear explanation, of both, operation, and benefits of both!

Your videos are very well thought out and informative, keep up the good work

Nice, found this when wondering if I could replace the CV style carb on my 70cc moped with a slide style carb meant for a small ATV. I had always wondered why 50cc mopeds had such weird carbs. In mopeds, the extra moving parts and smaller jets means it can get gummed up with bad fuel pretty easy if you don't run them on a regular basis. I will be switching to a slide carb on mine just to see how if feels.

Great video, Thanks for putting that together. Very clear and easy to understand. :)

Dude, this video was awesome. You have made it so clear about the difference between the two, Thank You bro.

Great information! I have hsr42 and been thinking how good it really iş compared to CV. This video gave me the answer. The extra noise of hsr iş something I don't like and also noticed the tender əs of throtle control, especially on low speed (in town). But as told in video it really reacts quickly when needed. One thing that wasnt mentioned in video iş the benefit of idle control on HSR. İt really helps the cold start as you don't have to use throtle for it.

Excellent dude!! Larry

I had a lot of issues with my Mikuni42 and I ended up pulling it off and putting a CV back on the bike. The Mikuni was a noticeable difference but my bike never seemed to like it and the float jet constantly moved out of position and would overflow the carb. Put the CV back on and the bike sounds and feels much better (it's like those engineers knew what they are doing).

yup any aftermarket slide will be worse than oem one if can't play with carb

It’s all about itemization , the flat slide does it better . We had big performance gains through the off idle to mid range on 2 valve Ducati motorcycles . Not only did it increase the mid range significantly but gas mileage was increased dramatically .

A great help to me. Now I am clear that in some carburetor you can control the idle speed by controlling the fuel by turning the screw where as in some carburetor you are allowed to control amount of air to the carburetor for controlling the idle speed.

Wei used to run the keihin FCR flat slide on the R6 back when they were carbureted. It gave you about 3 horsepower but required different jetting from 80-100 70-80 and below 70 degrees outside temp. If you got the needle position and slide cutout right they ran great. They don’t make the bike jerky or anything down low, if you crack it open at low rpm it just bogs the engine. If you like screwing with jets all the time have at it.

Could you post a link to the air intake that has on it. That looks pretty sick

Thanks for your video. I think you may be referring more to these on big street bikes. I have a 1987 Suzuki DR200 dirtbike that has a Mikuni 42A21 pumper or Mikuni TM28-1 (the part #'s I have found but not 100% sure)....it's definitely a Mikuni flat slide w/accelerator pump. I bought the bike used with carb apart in a bag. I had no idea it would be so difficult to find parts for....lol. I have found CV carbs online that say they will fit/work but was unsure if I should even try? I will be just trail riding and to me it almost sounds like the CV would be better for my situation. What do you think? I know the flat slide is missing the pilot jet and extremely dirty. I just want to get it running and have no idea about engine , clutch, etc. I can "usually" tune a carb fairly well but never worked on these flat slides with the pumper. Thanks in advance for any help.

Outstanding!

Sir how did you make this video on which software ?

My bike came with a round slide carb and the bike stalls if I give it too much throttle off idle any advice

Hey man. You seem to know this stuff better than anyone else. I"ve got some old Mikuni BS32SS carbs off an 86 Katana 750 that I'm fighting with, and I'm not at all understanding the pilot screw. It's on the engine side, but as far as I can tell, the pilot screw is metering the total air/fuel mixture being allowed into the engine at idle, not actually affecting the AFM. The only air passage to get past the butterfly, first passes the pilot jet before going all the way to the top of the carb and then back down just behind the butterfly. Then, there are also 3 other small pilot ports just behind the butterfly, which cannot be metered in any way, which seems crazy? My problem of course is that while I seem to be able to tune the idle system just fine, I have no control over what those three pilots just behind the butterfly are doing. So as soon as I crack the throttle, I end up super rich and boggy at low RPM, low throttle. Presumably this is because either those 3 pilots are too rich for small throttle openings or for the air being drawn into the system at low RPM. Or perhaps my needlejet is coming into play very early? I love your animations as they make this shit super clear, but none of them show what I've got with my pilot. Yours all show that the pilot screw is clearly metering either the air or the fuel individually.

Great video man. I'm about to run dual Mikuni 38mm flatslides on an Intruder.

Wow my Harley chop I have owned for 3 years came with HSR fitted and it pulls away like no other bike I have had. It jolts away at every set of lights, not smooth.

@thakery5720

4 жыл бұрын

Depending on what other mods you have made ( airfilter/pipes or engine), the pilot jet may need changing (richer) and the needle lowering to weaken things off. Lowering the needle will make the bike run weak at 'closed off' throttle positions so the pilot may need enlarging - don't forget to adjust the air screw. The main jet rarely needs to be much bigger than the standard one for the size of carb. The notches on the needle will raise or lower the needle about 1mm each notch - this is a very big adjustment, you can also get thin washers to put under the needle clip so as to raise the needle just partway between notches. The pilot jet supplied with the carb is good for standard engine/air filter and pipes but may need to be richened. The extra fuel it gives the engine is always there throughout the opening of the carb and so the needle may need to be lowered to weaken things back down again, so do not be tempted to make the main jet bigger. The needle being too high can mask the need for a richer pilot jet - this can be seen by the bike's engine overheating if you ride with the throttle closed a lot in traffic etc. You may then lower the needle a notch but find it needs to be raised a little from the lower setting with a thin washer or two so as to effectively only lower the needle a half a notch or so depending on the thickness or the washer(s) used. Highly tuned (altered) engines need a bigger pilot jet to allow the engine more fuel at low revs (throttle openings) as the suction is lower ( - the engine is 'off cam') and finds it hard to suck enough fuel through a small jet making it a weak mixture. As the throttle is opened and more air is sucked through the carb (more air than a standard engine/ airfilter and pipes would allow), it starts to suck too much fuel through the needle and needle jet combination and that makes it a rich mixture, so you lower the needle to weaken it a little. Pilot jets to go to may be 27.5, 30, 32.5 or maybe even 35. The strong pull you mention as the carb is currently set indicates a needle that is too high as the mixture is rich and gives excess torque - my sportster with Hammer cylinders and cams along with a flowed heads and open pipes has an HSR 45 fitted with a 32.5 pilot, needle is lowered one notch but raised a quarter notch with a thin washer, and it has the 175 main jet that the carb came with..... That is just an example not a recommendation...... hope you get it sorted !

New subscriber KaMotoFriends and Thanks for sharing 😉

Excellent. I'm familiar with mikunis and I love the adjustability. I find these videos cause I got an old Honda with a muddy off idle/ acceleration until I hit about 5000rpm. Then it cleans up and the power disembark is very noticeable. Makes me thing pilot jet or ckt is clogged. Or possible my slide and diaphragm are trash Well see. If a cleaning and adj don't fix it I'll just get a mikuni kit .

@HighGear7445

The potential is there ( as it can support more power ) if you wish to go with hotter cams ect. Personally I would only go to stage 1 for longevity. Harley engines have long strokes and piston speed comes into play here with hot upgrades. You can only rev them so high. Great engines for cruising and midrange torque

Please do one of these with the FCR carbs!

@@samstinkeringaround8961 basically from what I got from this is cv is more fuel efficient, flat slide gives better performance. If you are wanting more horsepower you might be disappointed with a flat slide carb. If it was me I would buy a big bore kit before a carb. That way you have more power and the acceleration is smoother. If you buy the big bore kit and still need more power, get a performance carb and make sure your pipes arent smaller than the diameter of your exhaust port. The more air you can push in and out the faster you can go in simple terms
