Thanks for the feedback.
Getting there..so far ( over many years):
Twin plugged & gas flowed
Moto Israel two into one exhaust with HPN baja ($$$!)
Thinking of getting sachs or siebenrock cluch
Other mods include:
Marzocchi fork inserts & Ohlns rear
Four calliper front brake
Local mechanic thinks I may have a bit of piston slap & valve wear but getting second opinion.
Bottom line, love the bike doubt going modern so considering rebuild for smooth use till I go grey..
