Hi Simon, thanks for the introduction. I was living in Bangkok for a while (in fact my MC16 track bike project is still there - in boxes - in storage with a couple of other bikes).

I found Tyga very useful for parts and had quite a few deliveries of bits for the '16 and also the MC21 that I have in the UK. I think it was wise to get Matt to look at the engine - there are very few people I'd let work on my engines, and as the 250cc NSRs were grey imports there aren't many about, and presumably not much expertise.

There are a few Facebook groups for NSRs in Thailand and some of them list spares for sale. I did import a few bits to Bangkok from Japan but it proved quite expensive in the end.

Anyway good luck with the project, look forward to seeing how it comes along!
