Good catch evil e, I got it back to normal about halfway into the tank when I noticed it would slow down when braking. It seems to be running great now and I'm on my 6th tank, haven't even tried to tune for speed yet, heck I haven't even played around in 4WD high yet. I'm starting to get some really nice wheelies, there is definitely a lot of power for that in first gear.

One question I had about it was in low going down a straight away it won't shift to second. The engine is *****g out RPM wise but I realize that because the 2nd speed clutch is on the spur gear the gear ratio is not aggressive enough to get the clutch up to speed to shift. Is this normal? Or did it already shift and I didn't notice because it happened so fast?

I'll post some videos as soon as my brother gets back to hold the camera. Thanks for the help everyone!
