I was out riding the other day and went over a pretty long stretch of very rough terrain at a fast pace and the Cat just quit running. I am assuming that the float in the carb got confused but I'm not sure, just wondering if anybody else has had this problem.

 

yes i have but i haven't found a cure. my guess was floats too but when i took them apart they looked fine had nice spring loaded seats
couldn't see any thing wrong. so if you find a cure other than slowing down ( thats all that worked for me) post up.

 

Have you heard from others with the same problem or am I the first? I guess what I'm asking is ; does this affect most 650's or only the ones we bought

 

my 650 likes to sputter after a long day of riding hard, and doesnt like to idle right aftert that. The dealer checked it over and made it idle a bit higher , he said it was low, hopefully that will solve my problem.

 

ive had this happen before riding woop de doos for long period of time come to find out the check valve behind the tail light was sticking causing the tank not to vent correctly which causes the carbs not to get enough fuel to run and also wont idle needless to say i removed the check valve havent had the problem since

 

i have heard of a few other people with this problem on atv nation but no one seems to have an answer
that works. the check valve is a good one but i don't think it is my prob because i have ridden with the fuel cap loose to let air in and it still happened. i have even pulled the fuel hose when i was having the prob and turned the key off and back on and got a good shot of fuel so i think the prob is in the carbs or like my old 460 ford the pump cant keep up with the demand when you are really gitin it.

on edit
i really don't think that many people ride these big *** bikes that hard or you would hear of this problem more often.

 

Check your air filter, this happend to me, after an oil change, and we discoverd that due to the Hi crank case pressure these machines put out, if you put the oil up to the full line, it will shoot into the air box, and run like crap, until it drains out of the foam air filter. Happen to me, after a hard ride in Jackson county wisconsin.

 

Funny you should say that pigsticker since it happened right after an oil change, I haven't had it out since, but I'll have a look at the filter.

 

yes, you need to split that line in half. otherwise it will keep doing it. I am positive this is what it was.

 

sounds like yall could use a polaris!!!!!!!!! lol
