I had just recently got my Banshee out of the shop after having stock bore Athena nikisill coated cylinders and pistons put in it, adjustable timing plate on the OEM stator, went from I believe 17 or 18 mm domes to 20s, clutch basket rebuilt, v-force 4 reads. The shop had it for way too long and I rushed him to get it back to me after a year and 10 days he said he hadn't had a chance to tune in to carbs and I told him not to sweat it that my brother is a two-stroke savant. Problem is my brother is out of state working for the next 3 months. The bike will start first or second kick and idle flawlessly, but anything past a quarter throttle and it bogs and starts backfiring predominantly out of the left cylinder. I put brand new spark plugs in it kicked it over revved it three or four times shut it off pulled the plugs and the left plug was black and oily and wet. It's got 50 fur pilot jet, and 162 for the main Jets my needle is in the dead center. The timing has been Advanced plus four. Please any help on where to start and how to fix this I'm dying to ride my bike. If somebody can help me out I can take videos of it running or whatnot and I'm very mechanically inclined to follow instructions on what to do.

Wow really? I was told these are better than what I had.

Brand new V-Force 4

My jets are 150 main 50 pilot

Who are some of the favored Banshee shops or builders in Arizona? I live in Payson so Phoenix being the closest.

Is it possible after adding the adjustable timing plate and advancing the timing and bumping up to v-force 4S and triple exhaust ported cylinders I would need to add bigger pilot Jets? Also I have not had the exhaust off on this bike but where my expansion chamber meets the rest of the exhaust where that coupler connection is on the left side is clearly leaking as if I let it idle I see smoke coming out of the coupler. Does that need a gasket or o-ring?

Keihin 33mm carbs as for the Jets they are the same jets that were in the carbs when I dropped it off prior to having the top end and other minor parts added.

How much for a turbo set up for my 01 banshee?

Keihin 33mm carbs and I don't remember what Jets were in it but the same Jets are still in it from before I took it to the shop and the bike ran perfect. It is the left side that is backfiring. And both pipes seem to be getting equally hot.

I just had a local Banshee guy rebuild my top end with Athena stock bore cylinders, pistons and rings, adjustable timing plate +4, reforce 4 reads, also got rid of the K&N filters and switched to UNI filter pod filters two stage. The bike also has FMF Gold Series fatty exhaust, cool head, and I went from 19 mm domes to 20 mm domes. The bike starts first kick but when I go to give it throttle anything past 1/8 of a throttle the bike just bogs and acts like it's starving and is backfiring I believe out of the left exhaust. Both pipes are getting pretty much equally hot and smoking the same. What could it be and where do I start?

Does any one have info on turbo kits for Banshee's? Also the best way to add led lights to my banshee?
