Upgrade stock engine

[Jonstewart1979]

I am wondering if I can increase the displacement of my stock MT (30cc) by simply bolting on a larger top end. If I can, who is the stock engine manufacturer and what style (number of bolts)?


Thanks!

The stock is 30.5 cc and made by HY. You can use any of the CY upgrades for a HP increase. A ported head will get you a large increase in power very easily

Count the number of bolts in the cylinder to see if you have a 2 or 4 bolt.
