stalling with new pipes

Ive had a problem with my 93 Banshee since i got it last march. It usually happens if im following a slower rider, or going down hills. It will stall, and not be able to start back up for like 5 min of sitting. I pull the plugs and they are not fouled. They are a nice brown which tells me the jetting is good. It runs good at high RPM.

It didnt use to happen so much untill i just installed FMF Fatty pipes and PC2 silencers. Now it does it frequently.

Im running .020" Wisecos, mid range porting, milled and rechambered head, clamp on KN filters with outerwears(stock air box not being used) FMF Fatties. At sea level, in stock carbs, i run 380 mains, 32.5 pilots. I run 92 octane with [email protected]:1.

It ran great with the old school FMF pipes, and only occasionally would stall. The installation of the new pipes makes the low end feel weaker, richer, stalls alot more, mid to top is more powerful though.

Im considering taking out the 32.5 pilot jets and installing the stock 25 pilot jets.

Any comments?

Re: stalling with new pipes

Stalls going DOWN hill? Sounds wierd. Dumb Question: Do you have spark during the 5 minutes that it won't start? I had a problem once with the wire harness. A bare spot was grounding to the frame and it wouldn't run. Maybe an intermittent problem that is slowly getting worse, or maybe the new pipe installation moved the wires around to a worse spot. To fix mine, I pulled the entire harness off the frame and added another layer of tape.
Next time it does it, pull the fuel line of the tank and make sure it flows. One other thing that happened to me was a clogged vent line to the tank. Ran OK until there was enuf vacuum in the tank to stop the flow.
Good luck

take a look at your jet needle it might have to be replaced. mine did the same thing and came to find out that the needle started to become square. i replaced it and it never did it again
