In my 3 gear V50 L (1967) I'm planning to mount up to 75 cc racing cylinder. If any of you tried a mild tuning of this model or has knowledge from elsewhere, plse help solving the following dilemmas:
- which kit would be best?
- is upgearing necessary, and if answer is possitive, which specific parts should I buy?
- what size of the main nozzle would be proper?
Thanx in advance!
