Well i know my jetting is screwed up know but it was perfect i started with i belive 270s when i got my pipes then i for a k & n and bumped up to about a 275 or so well now ive been trying to figure out which is better air box lid on of off..... now i have it off and am running like a 305 jets i belieive i may try putting 27.5 pilot jets in.........will porting make it harder to start and shit though.......

It may sound stupid but I would really like to try it myself, my dad owns a Yamaha Dealership and he could help me im really just looking for someone who has done it succesfully or can help, there are many people who have done it I know but there are different ways to do it do you bevel the outside edges of all 4 Intake ports? If so do you bevel all 4 sides of each port or just the top side of the ports.....I really need a diagram or something...I will look around on the net somemore All im pissed about is all the damn 4 strokes like the damn 450's and the raptors and the v-force......although I do respect their awesome torque in the trails and the track. I want information on how to make my banshee (the bike ive loved for years) run good and strong and not constantly bog out or overheat.........on a gravel road wrapped out in 5th gear on the powerband when i hit 6th it bogs out.....im tired or constanly playing w/ jetting and shit....ya know? Also what is the best Way to acheive more torque boggin out then shifting down and wrapping out is annoying..........

I have a 2003 Banshee with pipes, K & N Filter w/ no lid, and jets.....My friend has a brand new Yamaha 450 with pipes and a filter. He still cannot beat me in a drag.. but on the track its difficult to keep up w/ him

Boonman you sound knowledgeble i just posted a new message under tips and tricks : The Low Down on Porting and Polishing> i need information if you know anyone who is educated in this or if you are please reply

I have been reading alot on porting and polishing, I have a Buddy who has a dyno for fourwheelers and such...anyway i saw all the Banshees that were all modified as hell and only cranked out 46 + hp., then out of nowhere a Stock looking banshee gets on the dyno and cranks out 70 some, What i need to know is the pattern you port the 4 intake holes in the back of your cylinder. Please Reply only if you know what you are talking about thank you........

Hello I was reading your message when you said that a Vitos +4 Degree Key would be better for the woods than a +7 why is this..........? what do they do....
