I've got a 1991 zxr jap import just got it about 2 months ago. For some reason its losing power, when it gets to about 8000 rpm it backs off abit then the power band will come in about 9000rpm, has any one got any ideas why its doing this? also my brothers got a Honda VFR400 and it seems alot faster than mine. Is it possible it could be the exhaust because its blowing in about 2 places.
Many thanks
