BrockMoto Posted August 9, 2012 Report Share Posted August 9, 2012 Sounds like your float stuck a little... Tap it with the butt of a screwdriver should fix it, if it keeps happening clean your carbs real good and shut the gas off when you put it up Quote Link to comment Share on other sites More sharing options...

Motooutcastxxx Posted August 10, 2012 Report Share Posted August 10, 2012 update ... i ended up taking off the bowl to the carb and there was no gasket... could this be my problem? carb was clean inside Is that where it was leaking from or was it the overflow tube? Either way get yourself a couple of carb rebuild kits which are fairly cheap and rebuild them. At the very least change the needles, seats and those gaskets and you won't have that problem anymore. Keep in mind it's always best to disassemble one carb at a time since some of the parts are not interchangeable between carbs. Also it might be a good idea to get yourself a service manual if you don't have one, you can actually download one in the technical section. Just don't forget to put the choke tube back on once you bolt the carbs back up and you might want to sync them after as well. Quote Link to comment Share on other sites More sharing options...

BrockMoto Posted August 10, 2012 Report Share Posted August 10, 2012 yes, assuming the idling and "air sucking" is a new problem (post bowl removal) sounds like when you reinstalled you missed the choke tube.... That fuel leak should be a simple fix... and as motooutcast said... service manual FTW Quote Link to comment Share on other sites More sharing options...

That fuel leak should be a simple fix... and as motooutcast said... service manual FTW i just took the carbs off again and there is no tube to be seen... i called my local powersports store and they said there is no such thing... i kept on pursing and he said to adjust the floats and look at the needle and seat Quote Link to comment Share on other sites More sharing options...
Starwriter Posted August 10, 2012 Report Share Posted August 10, 2012 If they're stock carbs, there is DEFINATELY supposed to be a choke tube between the carbs. On stock carbs, the choke knob pulls out horizontally on the left carb. The right carb noes not have a choke knob Quote Link to comment Share on other sites More sharing options...
