What's the best sprocket size front and back for a rotax max running at larkhall scotland just need to get a base setting for my son who s just starting
Also main jet size would be helpful

A quick look online says 12/76 Junior and 12/82 for Senior, but not sure how valid that is. I would say give the track a quick call and ask, I'm sure they'll give you a guide.

For jetting all depends on the conditions of the day! I highly recommend this app as a guide. I think you can get it on iPhone too. They also do a NON evo app.

Evo jets you'll need say from 124 - 129. Pre Evo if I remember around 155 - 168.
