Can anyone enlighten my understanding of any advantages to be gained by
lightening the flywheel. It would seem to me that this would increase the
possibility of vibration from the engine, as you would reduce the inertia and
momentum that a heavy flywheel produces to smooth out the power fluctuations
between the power strokes of a four cycle internal combustion engine.
Thanks,

Dave,
Same drawing. Lightens by 9lbs [real money]
Well, I think you came up there with the only three possibilities. I'm
tending to think more to the side that the driven plate is binding on the
pressure plate. I'm certain it's disengaging from the flywheel. I can see the
centre of the driven plate moving on the splines. As you say it could be
still binding on the pressure plate. You guys who have also installed sealed
bearings on the spigot shaft and yet to try it should be OK.
Started taking the box out today, but the call of $1.00 beers at the local
brewery on Mondays gets the better of me. No, I didn't install the clutch on
a Monday!!! Maybe I should have done.
I'll have it out and stripped for inspection tomorrow.
More to follow.
