weird clutch problems

I recently upgraded a few components on my sonett and now im having a bit of a problem

I replaced the intake manifold and carb with a weber 2 bbl and ive got it up and running everything seems fine ..... I also lightened the flywheel


the clutch is "disengaging" or something to that extent

when i go into gear i do not get any grinds ... and when i release the clutch under acceleration is fine, but if i accelerate heavily, the clutch dissengages and when the when the rpm's drop .... it re-engages

it does not feel like its slipping it feels like its dissengaging because when it grabs it grabs hard and you can hear it ... makes kind of a clunking noise .... also when i slowly accelerate to say 4500 rpm's and i release the throttle, the rpms drop to idle, and i have to slowly bring up the idle in order for the clutch to grab again


i am completely lost, and hope someone has gone through this before and knows what it is ... thanks in advance!!!

could the flywheel have gotten machined down too far? New clutch at the same time? I've had flywheels resurfaced before that came back with a mirrorlike finish on them that gave a serious lack of friction for the disc. Been a looooong time since I've been under the hood of a sonett, but I've actually got a clutch job lined up on one so this caught my eye.

SOunds exactly like Freewheel a feature leftover from the 2strokes. There is a one way clutch activated by a lever on the top of the gearbox if it is not on the firewall above the shift linkage. It was there to keep the strokers from burning up on overrun. The freewheel is like a bicycle, you can power but then let off and it coasts.

The shock loads with a built v4 can be a bit too much for the freewheel. Just be easy as you get back on it. Let it engage nicely then romp on it. ;)

If you drive in freewheel and have a brake failure it gets fun. Better know how to hit the lever without thinking about it. Went through 2 boosters in my 95 till I fitted a c900 master cylinder w no booster.
