PostSubject: Looking to build a 770+   Mon Jun 24, 2013 10:19 pm

looking to bump my grizzly up to a 770 or so, just looking for some input on what else Im going to need to upgrade ie throttle body or electronics? any ideas or help would be much appreciated. Im wanting to stick with a 11:1 set up like I got and keep my stage 2 cam due to that setup runs real good now as is, but Im wanting to step up to the next level

Stroker crank port and polished head/throttle body. Go with ehs for the headwork if u don't have a machine shop already-his work on the raptors and grizzlies is second to none. He also has his own cam that is crazy powerful for the grizzly. You can also go with the 54mm throttle bodies off the raptors from what I have read. Its a lot of tuning too

Yea ive talked to a guy that had eric do his engine build with all the head work, I was looking today and found either a 54 or 47 mm TB that cam with a 550 injector, now I cant belive that a 550 injector would give you more fuel than the injector in the 700. speaking of fuel which kind of fuel controller should would we recommend for my build? I already have the EHS fuel controller but I'm wanting to go to a auto-tune type controller?

I hear the fuel monster is the latest and greatest-I'm saving for the PC V myself just as its tested and proved to work just fine with lots of bikes.

 I think it's probably a 550cc injector . And def go with Eric at EHS , I had him do my head work along with his custom grind cam , +2 valves and +3 tb when I put my 734 kit in . Very nice bump in power . I traded out my EHS controller for a PCV w/ auto tune , runs absolutely perfect now .
