Check to verify your outer cam chain (cam to crank) isn't off a tooth (advanced). Symptoms would be heat and loss of low end power.
That'll show about 30 psi difference from one to the other.
Have seen this many times, and have one coming in now, to attend to that same scenario.
Several years ago a fracas erupted(when didn't it? hehe) on another message board, as a do-it-yourselfer, installed one of our 95" combos, and the power was off.
He was upset, and we were evil doers.
We sat back and weaved our way through things with him, as we KNOW what our combo's produce.
After EXTENSIVE conversation with that individual, come to find out, he had a cam off a tooth, and the rings in the wrong grooves, and upside down to boot!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ONCE that was staightened out, the little 95"er showed 99 hp and 107 ft/lbs, as that combo was supposed to.
Never ceases to amaze us that this is the same type of guy that'll take his lawn mower in to be serviced, but by God, he'll boldly go, where angels fear to tread, into his Harley.
