I got the "6021" - Full Mod Zenoah 30.5cc 4 Bolt Engine

Full Mod - Our top of the line engines.

The full mod 30.5cc has proven to be one of the most popular engines we build. With the higher reliability of the 4 bolt Zenoah engines we were able to achieve more power with out sacrificing reliability. We put all of the knowledge that we have picked up from years of dyno and field testing and came up with a monster. To start we completely tear down the engines and perform the following modifications:

1. Machine combustion chamber for a proper squish clearance without stacking cylinder gaskets

2. Reshape piston

3. Lighten piston

4. Relieve piston to prevent seizes

5. Modify intake port for better flow

6. Adjust intake duration to our specs

7. Resurface all ports

8. Modify transfer ports for better flow

9. Enlarge and reshape exhaust port

10. Adjust exhaust duration to our specs

11. Remove stock crank and install 2mm stuffed crank

12. Install all new gaskets and c-clips when engine is assembled

13. Re-bevel all porting and stock bevels to prevent damage to the piston and/or cylinder

Can't wait to see it in. Do your self a favor and check all your dog bones CVDs and cups. If any of them are currently compromised you will waist them with that OBR. You won't want to tare down the whole truck again. You'll want to be spending your time driving. :D
