i have got a 375 powervalve banshee but i need more speed for some tarmac racing, any advise on engine alternatives

 

+2 or +3 swing arm and tires help alot too

 

yeah tires definately help... j/k
what about those boost bottles? I'm not a 2-stroke guy so do boost bottles do?
BTW I've seen some boost bottles in catalogs and the ones that say FMF are a lot more $ so they probably make you go the fastest [img]i/expressions/face-icon-small-wink.gif[/img]

 

portwork, tires, milled head or coolhead, lower it some and a longer swingarm. What are u gonna be running on(dirt, sand, asphalt)?

 

i really hope you ported it after you put your 4mm in it. If its not your just hurting yourself more. And CPI's WOULD run better on a 4mm then toomies

 

what about nos i went to a 300 foot drag wasd in west virginia and the fast bike had dual nos bootles or mabye they were boost bottle with nos stickers! dotn kno much aobut that area just an idea

 

yeah they ported it after they put the crank in.

 

the raptor motor owuld be a giant leap in the wrong direction

 

Cant tell if you guys are serious or not but boost bottles dont do $hit. Your better of trying to buy one of those colored powerbands. HAHHA.

 

They gave my banshee the performance needed, check the sig, lofl.
