Big test of the new R80 disguised as an R90S revealed the need for a pair of new throttle cables plus the usual service. No problem there.
R100R needs a basic service and a new front tyre. No problem there either.
I'm looking at a nice B31 next week.. plenty of fettling potential there. I do like them, one of the prettiest timing side cases imo.
I'd like an Interceptor...
