300cc tuning and performance

[EddieSC]

Honestly, I wouldn't mind running a 300cc upgrade on the spare motor I have kicking around just to see if I can do it but the lack of actual info is one of the things stopping me. It would definitely be nice to have an actual guide to reference so I don't grenade a perfectly good engine.

If you want a bigger bike, buy a bigger bike. If you don't know what you are doing, you are building a small bomb. Just my humble opinion.

If you pursue this project, please be careful but follow your dream. Done preaching.

Practical sense or not, it's fun! Then again I'm the type that turned a telecaster into a death metal shred machine just because.

Sometimes practicality can be overrated.
