i have a 2002 raptor with yoshimura headpipe & muffler + open airbox + k&n
160/155 main jets
it runns perfect but i want more power (trinty 686 or 727)or curtis sparks motor
i want to run pump gas 92octane
i ride mstly at sea level & sand mountain in nevada approx 4000 feet

 

I think both the Trinity686 & Sparks690 are excellent choices, their both very powerful and reliable. I've never been on one of Trinity's 686s but I know a few people who have them and they have yet to complain. I guess it comes down to whos cheaper and who has the best track record. Hope this helps.

 

approx what hp do they have ????

 

both make a good engine kit, but sparks may have quite a delay in getting the job done. check out trinitys site (www.trinityracing.com) lots of good info there, octane level will depend on the compression of the piston 11:1 calls for 93 at sea level but should have no problem with 92 at 4000'

 

what hp are we talking on a 686 trinity ??????
hp on a 690 sparks?????????????????

 

Jraptor- trinity 686- 63hp, sparks 690 65plus.
