You aught to get yourself a flow bench....unless...you already do!

Btw, I noticed you had KFX 700 cams in a prairie 700 once. Did you feel any differrence? I gotta pull the damn valve covers off to re-seal on my P700, and was thinking of the cam swap since I can get them cheap, and they shouldn't require spring changes.

I'm not doing any headwork on this setup. this is just bolting in pistons, cams, injectors and valve springs. so headflow machines don't really matter to me now.

Got it all done. Not that thrilled about the RWHP#'s (even though it's the best std bore I've tested yet) it came in at 64 rwhp on average. We did loose 1 rwhp peak, but picked up mid and top end. The bike runs fabulous, no oil spitting and no catch can, vented right to the airbox. This brute 750 can pull a muzzy full system piped and dyno tuned (71 rwhp) can am 1000 outlander by a hair.

The rwhp is far enough off the mark I want (need 5-6 more rwhp), so it's back to the drawing board until I get better results. Don't get me wrong. the kit is killer fast, ultra responsive and runs absolutely fabulous, smoother than stock, but not good enough for what I want to produce.

#1. pistons are a little too heavy, they need .010-.020 more deck height and don't need as expensive ring package.
#2 cams need to get more exact profiles made on the cams. they work great, but I believe can work better IF I can get the profile the way I want them

I know porting the heads and larger throttlebodies will add more power. but that's not what I'm trying to achieve. I want better base #'s from just dropping in the parts.

the PCV from the 2012 brute works on the t-4 for tuning it. but you still need the ECU flash to get by the limiters.

I have yst to try installing a 2012 bf 750 atv ECU on a t-4. I'd bet that would remove the speed limiters.

OR device called the speedo healer. where it tricks the speedo into thinking you are going slower than noted. but then the speedo would be off.


Honestly, I get maybe 1 call a month about a t-4. As time consuming as they are to work on I really have no desire to get into messing with them.
