Scratching my head with this one... I swapped out the Mikuni that came standard and inserted Keihin 38 PWK. Fitted a JD jetting kit and have arrived at : blue needle on 3rd clip, main 172, pilot 45, a/s 1 1/2.... running Klotz R50 at 60:1 with 95 octane. I have gone the rich pilot in an attempt to cure pipebang / deceleration chug.... better but not cured..... looking to clean up decel and have the power smooth to perky top end.... ageing bush bandit on weekend forest jaunts..... any help gladly excepted
If there are a lot of hours on the bike, replacing the silencer packing, having the exhaust seal at the header, fresh filter and top-end, stock cylinder head are all important.
Lots of guys throw performance mods at their buggered used bikes and wonder why it doesn't work out.
