Ok guys I am pretty sure it is my jetting but i am completly lost when it comes to jetting. My banshee feels really doggy and dosen't feel like the powerband is very strong. My Banshee is pretty much stock and here are the mods

 

Uni Air Filter with Air box lid removed

Older FmF gold series pipes

Stock carbs with the tors system.

Elevation is around 540ft.

I run 93 octane fuel and mix yamalube oil at 3 ounces to 1 gallon.

 

What should my jetting be at?

 

If you need anymore information please let me know. If i can't straitin this problem out i am going to sell it.

depending on your temp, your mains should be 290-300. ppilots should be 27.5 or 30 and the needle clip 1st or 2nd knotch from the blunt end. have you synced your carbs yet?

I am wanting to get it for temps 65 degrees and above. I have not synced my carbs but they dont seem to be out of sync.

So does 290 mains, 27.5 pilots and the needle clip on the 2nd knotch from the blunt end. Sound about what i need....anyone else opinion would be great i really am getting annoyed by this and would really like to figure it out.

i think that 310 main 25 pilot and needle in middle clip is more close to what you are looking for however your carbs do need to be synced anytime your touch the caps

Jeff at farmandsandtoys.com sells carb sync tools for $50. his name on here is FASTOYS. he can hook you up. or just eyeball it but it can still be very off by eye.

Allright, thanks MickNick, i will check them out first. I am still trying to figure out what sizes i need for sure...? i have heard anywhere from 290-310 mains and 25-30 pilots.... My shee seem like she is getting to much fuel because she is a smoker, boggy and running like shit.

haha, you're right. they should. but they don't up here. all i can get is "power jets" and they don't even know what sizes. outrageous pricing, too.

worth a shot, though

If you just plan on doing Banshee carbs yuo can usually find that carb sync tool on e-bay for $35.00

Mine came with the adapters for larger carbs as well.

 

 

Jeffs Snc tool is the very same one. for $50.00 with the adapters.
