Bonneville America Forums Forums Technical Forums General Tech Occasional Carb problems

Another Question to throw out there .
Every now and then , particully when its damp outside , on first start the engine starts fine but has erratic idle and the carbs (right) pops as if blowing back ? this clears after a few minutes at fast idle . Pretty sure its not the valves , thinking maybe sticking needle ? float ? dirtyjets ?

the bikes an 02 standard air box ,tors , standard jets me thinks and AI kit fitted
ANY THOUGHTS

check for loose rubbers. The oem manifold rubber clamps have a tendecy to be a bit loose and will allow air to leak in. When the motor warms up the rubber expands and all is good again.

Cheers
Ill check it out tommorrow and let you know

I going to hijack for a minuet.
1. would this sound something like purging a NOS system.
2. Would it make my air fuel mix off and more backfiring the usual.

Sounds like you have a vacuum leak.
