Hey guys, I have a 98 FIII600. *We've been out on the lake playing around and occasionally when I would pin it from a dead stop the RPM would only tack up to about 6500, and there is no power. *You let off the gas then hit it again and boom it comes back up to 8500. *This has happened to me twice now and its alway's when I'm starting from a dead stop draggin someone. *We pulled the carbs and then look extremely clean? *Stock Jets, Minnesota, 25degF. *Plugs look normal. *Any idea's?

Throw in some new plugs. *My machZ did this once, it wasn't really noticable until I pinned the throttle. *I guess the plug was partialy firing. *I Put in new ones and it fixed it.

I would check your raves also, make sure they are clean and working properly.

Make sure carbs are synced, rave valves clean and make sure its a good belt, should be about 1/8 above in the secondary clutch, that will make it bog if its dropped down in there.

How long has it been since your clutches got any attention? Something binding maybe?
