Well today I got my shee out warmed it up and tried to take off and it bogged way down and almost stalled, I had to rev it pretty high to keep it movin. After a slow lap around the yard and a bit of sluggishness at about 1/4 throttle, a grinding noise started (Sounds like metal on metal) from the engine area. It only seems to do it at a low speed and RPM and its only every so often, part of me wants to think shee's gettin ready to blow since it's a 95 and still on the factory bore and pistons but another makes me think it's the clutch because of the way it bogs when i try to take off from a stop. I have a compression tester but its from Harbor Freight so i don't know how reliable it is, the last time i checked it had 115psi in the left and 113psi in the right and that was about 3-4 rides ago.
I'm running 320 mains, needle on 3rd clip from top, 27.5 pilot and 2-2.5 turns out on air screw (not exactly sure how many) about 650 ASL
If anyone has a clue as to what this horrible noise could be, let me know
Thanks
