ok i have an extra set of stock banshee cylinders. i am wondering who to send them to to get a hi-rev port job. i was told duncan is te best and most consistant with their porting. i plan on drag racig too so please consider that. i would use the 35mm keihins.

 

if all your going to do is drag race I would have a company like FTZ set you up from what I have seen in the dunes the Duncan porting is more of a trail port

 

Duncan porting is good but it is not setup for drag racing. It is a mild high rev in essence. It will run and be fast, but not as fast as it could be. I love C&O, but you will probably have to wait a long time. Personly I would send them too port magic. Rudy kurtz is awesome. All of the ported bikes in our classes are either C&O or Rudy. K&T is also VERY good. I havent delt wiht them first hand, but I hav e seen there stuff and it flies. Duncan cylinders would be fast, but not as fast as they could be. Send them to a drag racing specialist. I have heard that FTZ is fast, but I have there ignition and carbs and wasnt that impressed. The carbs are pretty good, but the ignition isnt all its cracked up to be. I would like to see there pipes and porting though. I know there 250R's fly, they are the fastest I have seen, but i havent seen there banshees yet.
