I had 8000 miles with the 197 and even though the engine opened up good I get this feeling that it doesn't like to work hard and reluctant to rev high. I rarely get it above 6500 and I used to hit shift light every ride. The engine tone itself has noticeably changed as well and it is much more quiet now then it was before.
My uneducated guess is that the original air intake filter probably got too dirty. Could this be the reason? For a relatively dusty environment, how often should I replace the OEM filter? Also, is the OEM filter bad enough to justify getting an aftermarket one?
