Post subject:  Maico 490 Jetting

I am just finishing a restore on a 1982 Maico GS490 and need to know about carb jetting.

The carb is a new Mikuni round-slide and I ride between 4000 and 5000 ft in elevation.

I really just need a good starting point, the bike starts but doesn't really run well enough to do plug checks

Thanks for any help you can give me.
