Opinions please. Im leaning towards the throttle shaft seals.
Bike cranks and idles ok. Occasional pop/suck from carb and bike will cut out. I think i have an intake leak.
When i bump the throttle, I get a "Pssss" sound from somewhere near the carbs, havnt been able to locate the exact spot. If I hold the throttle its still there but its covered by the Revving engine. But the initial throttle bump results in a Pssss sound. Its audible. Dont have to listen too hard to hear it. Not a phantom sound. Its consistant and repeatable.
New boots and gaskets 6 months ago. New blind plugs on the stems. Tightened the boots and clamps, no change.
Gonna check my plugs later tonight for rich/lean - ness. I think the sound was always there, but the better I get her running the more these little things are able to be heard.
Thanks everyone !
