Last week I took the clutch apart, cleaned it, inspected everything, belt is good, cleaned and took scotch-brite and brake cleaner to the surfaces, inspected the secondary clutch, replaced the mangled buttons while I was in there…
Quad runs great but it still feels down on power, like it is running at 80%.
It starts and idles fine, it hits redline on the straights. It just lacks the "oomph" that it had the first year I owned it.
I am at about 1,000 miles now.
Now, I do have heavier tires, but they are the stock size. But they are 8-ply STI Rocktanes… They are definitely heavier than the stock tires, but the size is identical.
My buddy has the same quad, same year, similar mileage, but he has ITP Mudlite XL’s, which are about the same weight as my Rocktanes… His are 6 ply, but they are pretty heavy.
His quad rips and peels out and wants to wheelie, while mine just doesn’t any more…
What should I check next? I don’t see anything in the drivetrain binding, nothing seems amiss, the quad just doesn’t seem to have as much power as his, or as mine used to…
Maybe a flunky TPS?
