Thanks 2 stroke maniac,, hey you were unlucky with the rugby btw.
The problem here is parts availability since the nsr , as far as I know , was never sold here new.
Nsr jb. Thanks good info also. I guess if I have the barrels off I may as well replace pistons and rings rather than jut rings, what would you say?
Any idea how to determine which pistons are required for mc 16 or is it matter of removing barrels and measuring them ?
Thanks again.
We still have a month or so till the better weather arrives
