thanks for your help! id be lost without RU-vid videos nowadays! I actually had to buy a manual and take the time to read it and cross reference to get almost everything done. thanks again and keep up the great work
You guys do the best instructional videos, very precise and clear info, great focus on closeups. Very professional production quality. I wish all tech tip vids were like this! Keep it up!
Fantastic instructions very clear to someone like me who can struggle to understand things sometimes as people go too quick. This a patient good clear instructions 👌👌👌
Thanks for this video - it has been a nightmare to find some knowledge how to adjust the floats of my 1974 Yamaha RD 125 finished resto. It's almost impossible to find any motorcycle service in Helsinki, who can do/ or even know something of adjusting old 2-strokers carburetors.
Yeah,I completely agree,checking the float height is vital,my bike has a 20000 rpm so I think float height is vital,it is a 1987 Suzuki GSXR 4 cylinder,thanks.
I would be happy to receive your help on a problem I have with the carburetor as soon as I start the motorcycle I have a leak from the excess pipe I did a test and all the signs indicated a problem with the float or the valve after countless attempts that failed to solve the problem I decided to replace the carburetor and after the replacement the carburetor was on another motorcycle And it was normal. But my motorcycle again had leaks from the excess pipe, do you have an idea or a solution to the problem
How does float height affect the mixture? I thought the jets and adjustment screws control that. I had always assumed the float height is just about keeping the chamber filled so the jets are submerged during rocking of the bike.
Dang it, I can't refer to service manual because I changed the CV carb on my DR650 with a Mikuni. When I turn the bike of and it sits it leaks gas out of those tubes so I think I need to adjust the float. It runs faster than it did with the cv carb for sure but it doesn't feel right for all RPM ranges like it is now. I say it's 95% there but I think I need to get this float thing fixed if indeed that is the issue my bike has. I can't tell if it leaks when I am driving because I am driving and I don't have spidey sense to notice drops of gas at 25 mph. However, it does smell like gas so it is possible it is leaking even while driving.
Hey friend, I have a VM 22 clone carburetor on my sons mini bike. The brass tube on the inside of the bowl that makes it drip if it’s too high, that brass tube is level with the gasket. I set my float so it is 25 mm below the little brass tube, so when I check The gas level with the tube it sits 25 mm below the seem or the gasket , I hope that is correct. It calls for 25 mm. Please let me know thank you
@@krookedENT No, it didn't help. I now assume the float level is off. Which way do I bend the metal tab to reduce/stop gas from flowing out the overflow?
I adjusted my float bowl and now the manual choke won't work on cold start I have to give it gas to fire up also the plunger has no spring/ nakuru carb 50cc fuel only carb/ idle and fuel air mix screws
Love your vids brother. I took the carbs off of this v twin. I made sure diaphragms, jets, gaskets, needles, and all were good. Put them back on and still dies upon throttle. After checking everything numerous times, and replaced all lines, it still dies upon throttle but only revs up if I spray the carbs. Could a float out of adjustment cause bike to die upon throttle but still idle? Only revs if I spray the carbs. Any help appreciated. Thanks for the vids.
My guess is it could. If the float is set too low it's not getting enough gas in the bowl to handle throttle but could handle idle. My problem on my KLR I'm thinking is the it's set too high and it floods the carb which makes gas go out the overflow.
You dont have to have all that to set float height. Length of see through Tygon tubing placed on drain nipple on float bowl. Never fails, spot on. Finally a video that's shows the correct way.
Please my motorcycle atv sound like the airflow is blocked but as I move for sometime then the speed come back to normal and speed well but If I lowered the acceleration and raised the speed again the same problem come back again please help me
Do you have a pwk 38 carb? I’ve been having the same trouble got a full rebuild kit on eBay but I didn’t get a new float just needle valve. What are you having trouble with?
My bike idles low and then stops when I rest it on the kick stand. It sputters a little in the hills an won't idle on steep inclines. But it runs like a train on flat ground. New carburetor. Could it be the float height?
All you need is a length of Tygon tubing you can see through. Place it on bowl drain nipple, hold hose up beside fuel bowl, open drain screw, the fuel level in the hose will be the same as level in bowl. Make sure there are no air bubbles in the hose. You can move the hose up and down, does not matter, level remains the same. Simple physics. I like my fuel level just at or under where the bowl meets the carb housing. You dont need any fancy tools or gauges. You do have to have a fuel bottle that you can hang up above the carb. I clamp my carbs in a table vise. This way you can leave carb sitting with fuel loaded against the float needle all day to check for leaks and test the float needle to see that its holding and not seeping fuel, flooding. I do carbs almost daily for years, this is the best way and easiest to bench test float level. The more fuel you have in your test bottle the better.
It can, but it's more likely to have something else going wrong. Make sure the you have good compression and spark and the right spark plug. As long as those are good, verify the float height is correct, then work on your jetting. (make sure the air filter is clean and in good condition.) -Charles
Ooh, I forgot , the kits usually came with a cardboard gauge to measure the float height also ..not no more though ..its made by corperate, and they could care less about customers , they already got your money ..
