I has a "new to me 1997 Indy 500" It seems fairly non responsive in the low RPM range. Idles not too bad but dogs from throttle input- up to about 4500-6000 RPMs than runs fine @ about 7500RPM. even before clutch engagement tapping the throttle doesn't seem crisp and responsive. The local shop claims they had the carps all apart yesterday and checked the clutches and they still can't seem to find the prob. Occasionally if under load (heavy snow or starting going up a hill) It will bog to a point of not even moving unless I keep the RPM's up. Machine starts 2nd pull and doesn't seem to flood. any help would be appreciated greatly.
