Yaxy Posted January 27, 2006 Report Share Posted January 27, 2006 PSi is one of the elite few when it comes to design and the manufacturing of high performance engines. Unfortunately they are 99 % sleds and not really big into quads, However I have a PSI ported shee and I kick alot of ass at the drags and the bike just runs incredible. Last time I knew there adjustable heads ran about $500.00 and for most an adjustable head is not necessary. Chris Quote Link to comment Share on other sites More sharing options...
Fireroad Express Posted January 27, 2006 Author Report Share Posted January 27, 2006 looks like they are making banshee monoblock cylinders(w/ power valves). no dial-a-dome heads though. www.psipowerinc.com Quote Link to comment Share on other sites More sharing options...
