Originally posted by rapidray View PostI build 1229s all the time & they are great "bang for the buck"! I build BIG motors also but a 1229 is the least expensive of your choices. It's not difficult to get 150 at the back wheel with a 1229 but it DOES require headwork to do it. You already have carbs so pistons, cams, springs, porting, & a GOOD valve job will get you there. There are other things you will need though. A modified clutch hub, oil pump gears, cam sprockets, cam chain tensioner, valve seals, cam chain, etc... It all ads up but can be a VERY fun package & very durable & user friendly when done correctly. Let me know if I can help you. Ray.Last edited by Guest; 12-20-2014, 11:34 PM.

CP pistons are in my big engine race bike. love 'em. after a whole season I tore down the top end and could not believe how light the wear marks were. ball hone, reinstall, keep on racing. third year and I'll skip the off season teardown.
just to add -I have put together an engine using a welded heli gear small end crank - I am going to run nitrous on a pro street chassis and see if it will last a season. thinking about spraying enough to run 9:50 street fighter index.SUZUKI , There is no substitute

Go to the Brock Davidson Performance website and fish around until you find the 2012 ZX14R project bike Louisville Slugger. I sold the bike to Terron Babbage this year. The bike made 225 RWHP running stock internal engine parts. Stock wheelbase, stock tire, slammed, 0 wt. Ailsyn synthetic oil, ceramic wheel bearings, MR12 fuel, Brock's header & PC5 it ran a best of 8.80 at 160 at Indy Raceway Park. Having a 150 pound pro rider also helped. The whole story is there on video.
