Just got back from the dyno with a friends DS. In march we dyno tuned it to 50.6 HP Put one of the Boms's 14-1 pistons in with noother changes and pulled 54.7 on a fat main jet . Nice gains from only a piston. Looks like we still need to bolt more stuff on though.

 

Congratulations on the gains. What other mods on the bike?

 

that was my bike. all i did was install the 14-1. a 4 hp gain with being off on jetting. crazy said there was gains all the way across the board! and remember we are not racing dynos!!!lol....i might be able to post picks when i get it back, thanks again john!

 

oh i forgot, that was from the 11.5-1 to the 14. and thanks for the help bom.

 

i need to get the BOLT ON raptor on that dyno sometime!
