Hey everyone, been awhile since I could get on due to lack of Internet accessibility. I was wondering what ways I could get more horse power out of my 2-stroke 49cc mini chopper and if so how without ruining my engine or other parts. I am aware of muffler modding but not sure how exactly. Thank-you in advance for any comments

Portin the head and blueprinting the engine with a HP clutch an rocket key. CAM2 made threads about porting and blue printing also about rocket keys. Look under 2stroke how to's and 2 stroke midbikes.
