04bluyfz Posted January 1, 2012 Report Share Posted January 1, 2012 i am having a problem with my bike. if i drain the carbs out and then just fill system back up, the bike will start on first kick, but if i let the bike sit for a few days and not start it it will not start. if i squirt some fuel in the carbs with filters removed it will fire up. They are stock carbs that have been cleaned and rejetted correct specs. the bowls are on the correct carbs, slides are in right, just cannot figure out what is going on. If i start it everyday after refilling them it will start first kick. when it is running it runs good. By refilling i mean i just shut the fuel off at the tank drain the lines and carbs and then hook them back up and just turn on the shutoff. Thanks for any input and help Todd Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 1, 2012 Report Share Posted January 1, 2012 (edited) Sure your fuel is good and you have good oil? Maybe you have a float sticking and when it sits for a while its filling up with gas and flooding it... Maybe try some different plugs. Checked your compression lately? What do your plugs look like? You could pull the carbs off and clean them real good. Check float height, etc. - Jared Edited January 1, 2012 by BigRed350x Quote Link to comment Share on other sites More sharing options...
04bluyfz Posted January 1, 2012 Author Report Share Posted January 1, 2012 Carbs are clean, plugs are new, gas and oil are fresh. I have thought about the floats sticking open. I need to pull them out and check the float height. Motor is new compression is good. Other than when it sits it starts and runs good.

Daniel Gottschalk Posted January 1, 2012 Report Share Posted January 1, 2012 I'd check ur float level. Mine stuck open and filled my entire motor up with alcohol. Seemed like it blew 2 gallons out the exhaust once I finally got it started. Quote Link to comment Share on other sites More sharing options...

alky350banshee Posted January 2, 2012 Report Share Posted January 2, 2012 When u spray fuel in thru carbs, does the carbs already have fuel in them? Quote Link to comment Share on other sites More sharing options...
04bluyfz Posted January 2, 2012 Author Report Share Posted January 2, 2012 Yea, for instance, right now the bike won't start, but if I squirt fuel in the carbs it will start. Quote Link to comment Share on other sites More sharing options...
alky350banshee Posted January 2, 2012 Report Share Posted January 2, 2012 Sounds like its not gettin any fuel. Id clean n check floats n go thru all the carbs again. Quote Link to comment Share on other sites More sharing options...
monstermike Posted January 2, 2012 Report Share Posted January 2, 2012 Make sure the float is connected to the stopper. If not it will not let any fuel in. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted January 2, 2012 Report Share Posted January 2, 2012 My son's does same thing. It can sit for an hour, day or two (with fuel off) and it will start just fine. At about one week it takes a snort of starting fluid to fire off. My thought is that fuel is refined for closed systems on road vehicles and the "high end volitles" evaporate out of the fuel in the bowls, then it's not good enough to fire off. A friend had a quad that wouldn't fire off with 3 month old fuel. Fresh gas good to go. Quote Link to comment Share on other sites More sharing options...
04bluyfz Posted January 2, 2012 Author Report Share Posted January 2, 2012 Thanks for the help guys, I will double check the floats and get some fresh gas and see what happens. The bowls fill fine when I first hook it up, so the floats are opening. Quote Link to comment Share on other sites More sharing options...

The bowls fill fine when I first hook it up, so the floats are opening. If it starts when you spray whatever through the carbs, you're not getting enough fuel to the cylinders. I'd yank the carbs off and clean them good and go up a size or two on the pilot, if it starts then, go back and adjust your jetting. Sounds like its a carb issue...

04bluyfz Posted January 2, 2012 Author Report Share Posted January 2, 2012 I've thought about the pilot, but if it was the pilot why does it start fine if I drain the carbs do nothing else but turn the gas back on? Some things wrong its just not making sense to me. Quote Link to comment Share on other sites More sharing options...
