Hi

I bought a highly modified NSR last year and a bit ago, and succesfully managed to blow it up.

I have had the barrel off and the piston is mullered, got a fair idea what i need to do to sort it, but my predicament is that i thought it was a mc21 but the numbers on the crankcase say mc16 - did they share cranckases or is it a mc16

any advice would be appreciated as i need to buy some bits.

Lastly are there any owners in and around Harrow in North West London

thanks

Bren
