Well after getting my CCT in the bike seems to run a little different. A buddy gave me his old D&D pipe to see if i like it.
So the bike doesnt want to idle when warm, the RPMS just drift lower and lower untill it stalls. Then if i try to adjust the idle....the RPMS with idle normal....but when i rev it....with float for like 5 seconds then fall back down. This sounds lean to me!?!?!
Also i noticed the old owner put a K&N filter on it.
So i pulled the intake boots and didnt see any cracks...i cleaned them up and applied a think layer or RTV to the bottom just incase they wernt sealing. Still doing the same thing....
Does this sounds like a vacuume leak?? or a lean carb contition?
Also i put my hand over each carb while it was idling...and one seem like it want sucking as hard as the rest were on my hand. I hope its not a cracked piston or a bad rings.
Just for a test....I took a sock and jammed it in the air filter and the bike runs perfect. Took the sock back out and its back to bogging and running like shit. Put it back in, and perfect.
Do i need a stock air filter, or is this still a sign of needing jetting?
The new pipe breaths better, to compensate you need to increase the ammount of fuel you're able to take in. The sock limited the ammount of air therby making it richer. A stock air filter only runs a little poorer than a K&N, I would suggest you need to shim your needles with one washer each and turn your air/fuel screw out a turn. I'd still go with a jet kit, you're just hearing it at idle now, when you really wind it up you'll notice a big ifference and a lean bike can damage the heads with too much heat.
