Hi guys,
I have relocated to muscat, Oman and found a 1990 mc21 SP in cabin racing colors for sale in Dubai.
I emailed the guy and he says he bought it from johnnyMac and motor was rebuild by gt engineering in the UK. He said the only thing wrong with the bike is it needs new fork seals (nc30) and a PGM. My questions are: what causes the PGM to go? Is it a simple task of buying a new one fitting it and that's it? And does Mr JohnnyMac remember this bike?
He seems like a genuinely honest person and if you are reading this I do apologize if I'm offending you but I have been stung before and I just want to be sure that it won't happen again.

Thanks for your time

Jono
