What do you guy's do to keep the gas from comming out of the carb overflow when your doing a wheelie ?

 

Never noticed any fuel overflow from the carb's and if there was it had no effect on the P700, I try not to go over 300 feet on the rear tire's afraid I might blow the motor, cause lack of oil standing strait up like that. Unless your on a 2 stroke forget the fuel overflow and think about motor oil and where the oil pickup is.

 

Some bikes have the overflow problem, some don't.....My EX does.

Not sure what the fix is.

Yeah my 300ex has that problem. I just started doing wheelies and I am nowhere near as good as you guys LOL but you tips on one of the other topics helped alot with me getting used to the balande point. I tryed standing on the grab bar and it is alot better THANKS for the advice!

 

also have the problem on my 2002 rancher, i replaced every component in the carburator, still have the problem, something im just going to have to deal with, my buddy's 03 doesn't do it, my buddy's 04 forman does

 

yea my 300ex does that. i guess its normal it keeps the carb from building up gas.

 

All's you gotta do is adjust the float a little. Set it so that it shuts off the fuel a little sooner. Don't over do it. Start with very small adjustments until it quits overflowing. If you over do it, it will cause your bike to run out of gas when you do a wheelie or go off-camber.

 

Im pretty sure the reason is because the honda have carbs that shoot gas in instead of letting gravity work. This forces a lot more gas in. Thats why some quads may bog down when in a wheelie.

 

if u dont go back as far it wont leak out or try givieng it more gas in a lower gear it will use the gas instead of makeing it overflow

 

You're on the wrong track. Most carbs are gravity feed - no shooting gas. I don't know where you got that.

Overflows are used to exuast what it says - overflowing gas. When you wheelie, your fuel bowl spills over the level of the stand pipe - since the carb is now loosing fuel faster than it can burn it, the floats open up and continue the flow.

If you wish to keep it from leaking, run the overflow so the tip of the hose is in front of the carb, so when you wheelie, the tip of the hose is higher than the carb - this will not work indefinetly - it will drip after the weight of the fuel in the tank starts to push it out.

BUT I DON"T RECCOMEND IT - why :
The only REAL way to stop it, is locate the overflow higher than the gas tank, this is not probable.

CUATION: any technique other than overflow falling away from the carb may lead to flooding - becuase fuel will find path of least resistance, if the tip of the hose is HIGHER than the cylinder intake - if the floats were to stick open (by chance) the motor would fill up with gas instead of leak it out through the hose - if you carb drips fuel over night when parked, you shut the fuel off, right?? Well, instead of leaking on the floor, it COULD leak into the cylinder/wash the cylinder/burn rings/cause flooding/mix gas with oil lowering the vescocity.

and for what you said hitman1970, there is no oil pickup on a 2 stroke, or is that what you ment????
