powerman350 Posted April 19, 2004 Report Share Posted April 19, 2004 I went up to Sand Mountain, Nevada for Easter weekend and broke a piston skirt the first night. I was just gonna hone er out and throw a set of wisecos in it but I was having nightmares about my buddies piped 450 kicking my ass up comp hill. I want to get my jugs ported and polished and my head milled. I was wondering if any of you have had work done by Speed Tech (Mission Yamaha in Laguna Niguel SoCal). They have an article in the August 2002 issue of Dirt Wheels, Speed Tech modified Banshee. They say they can get 60 hp out of their motor mods with T5's, k&N's, delta v-force reeds with 320-340 main jets, 30 pilots and blaster nozzles. I wanted to see if I could get some feedback b4 I sent my motor off... Thanks Quote Link to comment Share on other sites More sharing options...
