Yes, certainly all that you mentioned was
not helping. I replaced the clutch set up including a new carbon thrust race.
Still problems and a metallic sound when clutch was used. Never got to drive it
on the road. Pull the engine and gearbox out again and start looking at
everything. The 10” replacement kit had burn marks on the release bearing
face. Three heat spots in between the fingers that hold it in place. How did
this happen, don’t know!!
The clutch plate had a very slight “kiss”
on the cage that holds the spiral springs in place. The cicular marks lined up
with the bolt heads holding the flywheel onto the crank.
So, how thin is my flywheel? It seems
29.8mm is very thin, average measurements that I have been able to receive for
s/h wheels are in the range of 32/33mm.
Have just received a measurement today
taken on an original lightened flywheel of approx 33mm. I can buy this flywheel
but is 33mm enough meat left on the wheel?
Lightened flywheels are fairly scarce
around here, this one is said to of come off a special equipment 120, did they
make them for 120/140‘s as well as “S” 150’s? New
lightened steel wheels are available so I will soon have to make the decision which
way to go. We have a 50th Anniversary Rally to attend to at the end
of March as well as my fiftieth year of ownership of my 150.
Thanks for all your inputs.
