Who did the work? any timed runs? what all did you have done?

 

My freind just had his 2001 banshee done at Mission Yamaha. Had full boost porting for more bottom end and port and polish and at the same time new top end milled head .070 no air box with K&N clamp ons and a V force. The bike rips hard everywhere. He saw the Mission Yamaha banshee in Dirt wheels called them up and talt to the owner he answered ALL his questions and so he liked what he heard and had them do it and LOVES what it did to his bike

 

Hows it run against your raptor and what is "THE COMPOUND"?

 

i had a trail porting done and it made just as much diff. as the pipes did when i first put them on

 

My raptor is just piped and he will walk away from me and he wieghs 125lbs more then me..

I own a T-REX top end that has been ported by Rossier Engineering in Wisconsin, i also own a stock bore top end that has been ported by 4 Wheel Thunder in Michigan.My next set up is a Cheetah top end with a 4 mm stroker crank all done by Patriot Racing in the state of Washington...Should be fun.

 

Isnt that T-Rex cylinder supposed to produce 140hp?!?? What is the Cheeta? is that Trinitys PVL?

 

The T-rex top end or more commonly known as the FMF PV cyls can produce very big numbers if set up correctly, i dont know if 140hp is reachable but i have seen 120hp with the correct set up.The Cheetah cyls are a creation of Calvin Pollet and right now they are the best aftermarket cyls you can get due to their revolutionary transfer ports desing, they are better desingned than even the T-REX cyls they produce more HP than anything outhere, you can get as much as 140hp out of them in thier most extreme configuration.Trinity along with many others sells them but they didnt by any means create them.

 

my dads got the national pipe and porting kit from duncan racing works good

 

I been looking at this for awhile.....http://www.twistercrankshaft.com/news.htm
