can i ask u a silly question of mine?what does a choke does?if the choke is on up position,is it ''on'' ??my bike usually leaks the fuel after somtimes especially when i cut off the engine kill switch.or when i shake the bikeit will leak sometimes before i start the engine.thats where i shake the bike up and down on the rear.whats the cause of leakage.i dont unferstand..lol
@Miralis27 The choke richens the mixture of the air and gas, either by blocking off the air, adding more gas, or both. If you have fuel leaking it is probably not directly associated with the choke, probably something else
On my 1983 Suzuki gs550l, I have a carb leak thats really stumping me. I've replaced both needle and seats, and from looking at it, everything seems to function properly. I have yet to test or replace the floats for being poreis. But I am really stumped when the carbs sometimes do no leak at all. I THINK,,, they seem more likely to leak when its cold. Maybe the bowl gaskets?
@jkrlabonte Could be, carbs leak from a lot of different places than this movie illustrates. This one really just focused on overflowing carbs, but they can leak from gaskets, fuel lines, connecting hoses, or other places. First step is figuring out from where exactly the leak is coming, next you can address it
By the way, if your video camera is like mine, it will have variable close focus depending on the zoom. It's counterintuitive, but most zoom cameras will have better close focus limits when set to wide angle. So, if you find that it can't focus because the camera is too close, try zooming to wide angle and you will be able to hold the camera closer. Strangely, the loss you get from wide angle is less than the gain you get from ability to hold the camera closer.
okay so my atv, which is similar to a bike in many ways, died while i was driving up the rams to my truck. it was leaking gas from the bottom of the carb, so i took it apart and dipped it, blowing air threw it as well. it doesnt leak anymore, but the atv will not start. the engine turns like a key in an igniton, and the exhaust puts out a little force that you can feel with your hand. help?!?!
@dwidthekid Oh well you may have fouled the plugs after flooding the engine when the carbs were leaking. Also make sure all of your air conduits are tightened well and that there are no vacuum leaks.
@dwidthekid Are you sure it wont go in? You are not stripping the threads? Look down into the spark plug hole and see if you see anything in there blocking its way, your engine may have eaten a valve
My 93 suzuki atv carb that i cleaned out and had gas leaking in it..I took it out again and noticed there is a place for a screw in the side bottom of the bowl that dont have anything in it... What kind of fitting goes in there..I havent noticed this before now..I guess this is why the gas pours out .. Thanks for more help
@Drumnguy77 That is probably the bowl plug, normally there is a screw there that you can remove to drain the bowls. You'll need to get another one. Go on bikebandit and look up your bike, they sell them for like $3.50
My 93 suzuki atv carb was cleaned by me other day and when i put it back together there was tremendous gas coming from bottom of bowl out of the long nipple with hole..What does this sound like? the float and needle felt ok..thanks for any help!
@Drumnguy77 That does sound like the needle is stuck open, either the float is stuck or the needle got dislodged when you were reinstalling it, or something like that.
hi again, just had a look ive noticed a fat clear pipe in the middle of the carbs and its leaking a lot of gS, IS THAT A BREATHER OR HAS IT BECOME DISLOGDED, cheers
@69kafil Well, without taking a look at a picture or something I cant say for sure. Sometimes the fuel overflows are located there. Or, that is the main fuel intake, and you have your fuel lines misrouted, and you are feeding gas into an overflow which is then flowing out of the gas intake. If you want you can take a video of the carbs leaking and send me the link, and I will take a look.
I have the same issue on my zx9r but it only happens on one car it leaks fuel but last time i put it together it moved up and down fine and my gasket looks ok. Any other issues?? this started happening as soon as I decided to clean the carb so must of been my fault please let me know
@zrultima Check your float needles, if the one carb that is leaking is the side that your kickstand is on, then almost definitely your float needle on that carb is stuck open
@zrultima Remember that both the floats and the float needles need to be able to move totally unencumbered. While you are in there check your float heights (I have another video up for that), which can also cause overflowing if they are off. Also be sure to tighten up all of your float bowls extra tight.
@mrmaxstorey It was working fine before I remove them I just took them off again and check the float needles and bowls everything moves freely...nothing is stuck any suggestion!@?
@mrmaxstorey Yes its coming from the top of the carb cover and leaking down i check the gaskets and they look fine its not coming from any hose because i check for leaks and replace the one that werre cracked so it coming from the carb itself
@mrmaxstorey Yes its coming from the top of the carb cover and leaking down i check the gaskets and they look fine its not coming from any hose because i check for leaks and replace the one that werre cracked so it coming from the carb itself
I like this video, but I'm have a hell of a time when 87 Yamaha just started it up today Jane.all the mission coils. But is doing the same thing as last year runs only with the choke wide open or partially closed. I did a compression check today. All cylinders are 95 PSI or 98 PSI in that range.
I bought it online three years ago have not been able to get it to run. Still, it will not idle for longer than a few minutes then it dies need your help in this matter. Thank you
@memberson It could be a bunch of things, first buy a repair manual for your bike so you can see what those compression readings should be, then watch my video on how to repair a nonrunning motorcycle, it should explain pretty much all of the usual problems which you should check first. Good luck.
Hey man, Me again, Ok, On the 87 cbr1000 project im working on, i did a half ass quick job on cleaning the carbs, now it starts and runs but it will only go about 60 mph max, what could be the problem? could my big jets still be clogged? or is it a bigger problem? it starts to bog down after 60 but runs fine below
@YoshiMan246 It could be a slight air leak, or a partially restricted fuel line. Also, you may r may not be jetted properly, if you have pod filters or an upgraded exhaust, you need to change your carburetor jets. Finally, can you confirm that all 4 of your cylinders are firing? If you have a dead cylinder it may act like that.
@mrmaxstorey No air leaks, Just got done checking that, Stock filters and stock exhaust, so now the scary part, how do i check to see if all cylinders are running properly? only 2 months into my classes so haven't learned this yet.
@YoshiMan246 Its actually not too hard, get yourself a digital touchless thermometer, like $15 on ebay or autozone, and track the temperatures of the header pipes as they warm up. Start with the bike cool, start it, then track the temps of the pipes as they heat up. If one doesnt warm up then you are not firing there, or one warms up way faster than the others, it is burning way too lean. This is a preliminary test but it could let you know wheres the problem. Also, did you synch the carbs yet?
@mrmaxstorey Thank's Haven't tried synching the carbs yet as i didn't think that could cause this issue, I am going to do another carb cleaning here in a bit, and actually clean everything real good. Then see what happens, If one of my cylinders isn't firing what's in store for me? maybe i don't want to know? lol
@YoshiMan246 Typically it is an electrical issue, you may have a fouled plug, faulty coil, ignition wire, something is wet, stuff like that. If you had a serious problem like a severely worn cyl with no compression you would see a lot of smoke, if you had valves which were damaged or broken you would hear a lot of chatter. Most likely this is something which is no too difficult to repair.
What would happen if one cylinder is overloaded with fuel? would it be enough to kill the motor? (im sure I have float valve problems. After sitting all winter my oil was diluted with gas) I have no gas dripping from my carbs though...On blocks even in gear (first and second) it runs great. While riding it dies soon after taking off (smells gassy) could the sloshing caused by the motion cause my problem. Thanks for your response earlier, hope i dont sound stupid, i know nothing bout carbs.
@jdogface Haha no worries dude, glad to help. If your gas leaks into your cylinders, it can lead to a very bad situation. It will foul your plugs and make your bike run poorly, but more importantly it will dilute your oil, making it much thinner, and therefore unable to lubricate your engine. Your engine will wear rapidly and soon the cylinders will scour. You need to change the oil anytime it smells gassy, and more importantly fix that float leak asap. Send a message if you need some more help.
@carlcbx Normally I would have, but I was pretty sure I knew which carb was the culprit. I only opened up #2 for comparison purposes. Anyways, this solved the problem and the bike runs great.
Good Day Mr. Max... can u teach me how to fix motorcycle???
