I like Debbies advice, if its going well keep riding it. However, being a 750 there had to be a reason for a compression plate being fitted. Check for an ID mark on top of the head, usually above the right exhaust rocker cover.
If its C that means the head is a Combat, the highest compression version of all Commandos. These had a reputation both good and bad. Bad when poorly set up and wrecked crank bearings before Superblend mains came along. Good when set up with correct carbs and ignition they go extermely quick and are durable.
C heads are shaved down to get higher compression and technically speaking the pushrods should have been shortend slightly. Where is the this compression plate fitted - head to barrel or barrel to crankcase?
