Couple of months ago my 660 went bang and sounded like a bag of nails as it ground to a halt. Opened top up and i had to wash the piston out of the crankcase in tiny little bits. New piston and pot kit (was looking bit oval with scoring) and has now been running fine for 2 months.

New problem with my contra/090 project, it has destroyed the new starter ring, anyone else wishing to convert a contra, 1, don't up the compression with a liquid base, 2, always use the decompression button, 3, check the ring quite often! I have been told that decomp buttons save the starter, but on newer models (and much smaller) the engine isn't really a problem to pull over, obviously if its a massive stonking engine and a metal-on-metal friction design, this is very important
