smackdoogle Posted October 21, 2012 Share Posted October 21, 2012 Put in a new fuel filter and realized that it would only flow gas for a few seconds before it turned into a trickle. This would explain my shitty idle especially when the bike gets hot. How do you clean out the fuel/gas cap vent? Link to comment Share on other sites More sharing options...
Member Contributer gll429 Posted October 21, 2012 Member Contributer Share Posted October 21, 2012 wire! a bicycle brake cable.. maybe compressed air with a good fitting rubber tip.... just wondering.. did you open the cap and see if gas flows faster?

Member Contributer RollinAgain Posted October 21, 2012 Member Contributer Share Posted October 21, 2012 Are you sure it's not your fuel pump? Rollin Link to comment Share on other sites More sharing options...
smackdoogle Posted October 21, 2012 Author Share Posted October 21, 2012 Positive it's the fuel cap. with the cap closed, the fuel flows fast for about 3 seconds then slows to a trickle. Open the gas tank and fuel flows continuosly until the tank is empty. If the pump wasn't working fuel wouldn't get to the carbs at all. Link to comment Share on other sites More sharing options...
Member Contributer Cogswell Posted October 21, 2012 Member Contributer Share Posted October 21, 2012 If you think it's varnished fuel causing the blockage, throttle body cleaner will dissolve it. I had a can of it - I think from NAPA - that had the small red straw on the valve so it could be directed in to tight spaces. The pressure from the can will also help dislodge any blockage. If you get the type that's safe for coated throttle bodies, it shouldn't be too hard on any rubber seals or gaskets. Brakekleen will also do the job and leaves no residue, though it tends to be hard on seals . Be sure to wear goggles - that stuff under pressure has a way of finding its way back to the operator.
