Scooterotica

Muggelo 200 small block kit
Franspeed super tourer
Mikuni 30mm flat side with power jet 50 open mouth
60mm long rod

Carb was running 230 main
Second clip down on needle

It's running to lean on plug chops I've dropped down one click on needle but bogs down now . Any ideas up main jet ?

Is this the same setup where you have already asked and answered your own question re a dyno?

...we do have best results with: pilot 25-27.5, main 260-280, PJ 40, standard needle with 2nd oder 3rd clip position
