end of season checks for the C110

the racing season is over now, so time to check the bikes and store them for winter.
At the last event the C110 started shifting a bit less smooth, so I wanted to open up the motor to see if I could find anything.

couldn't really find anything with the gearbox except for normal wear, well, not even normal as the bike is about 50 years old and all I could find was a small mark on a shift fork. Made some clearance there and that was it.

Then wanted to clean the clutch, as it acts somewhat as a centrifugal filter and found this:

oops, although I've seen them worse in pictures.

luckily I had a spare engine by now that still had a good clutch center, so this is going back together as it worked fine up till now with the extra preload washers with heavy duty springs.


Just one modification I wanted to do to the gearbox, I replaced the standard stopper arm with an S90 part, these have a little roller on the end, that might just prevent the selector to stick between gears. I've had this happen a couple of times so hopefully this helps, or the fact that I now swapped the old style shift arm for a more modern type, eliminating about 2cm of play in my pedal.
