Hi guys. A little help needed if poss. I’ve just got my new RB200 back. Been tuned and ported a little also. Running varitronic ignition at 17 degrees and Technigas pipe. I’ve decided to go with a Mikuni TMX35 but can’t find any jetting/needle info as to where to start off from for running in. I’ve got a full jet and needle kit with the carb. Up to now the carb is totally standard but don’t want to run it until it’s jetted somewhere near albeit on the safe side. Anybody got a starting point for jetting ?

Needle : 6FJ6 highest (richest) position
Needle jet: Q 0
