RG500 and RD350 base gaskets

Sad to say I had another thrust washer break! So, I have replaced the crank with one that has the thrust washers on the crank and am reboring No. 4, It will get a 57 mm piston kit and new small end bearing. I have cleaned up the rotary disk covers, and will be using a long open phase carbon rotary disk, the clearance is 0,3 mms. Will order a standard rotary disk.

Performance on the 350 was down due to raising the barrels with additional gaskets, so I am going to use thinner gasket material and hopefully find a compromise between breaking pistons and performance.
