Installation Instructions for 60cc or 70cc Performance Kits

!!! WARNING !!!!

This kit is for off-road use only and is not to be used on any unit intended for legal street use. In addition, this kit may produce more power than the moped was designed for. Use at your own risk!!
PLEASE INSPECT ALL PARTS BEFORE INSTALLING! THERE IS NO WARRANTY ON HIGH PERFORMANCE PARTS !!
1. Install piston holes to intake side. Make sure ends of clips are pointed up or down.

2. Install cylinder. Be sure to lubricate the walls - the cylinder should slide all the way down to the block freely. DO NOT FORCE DOWN! If the cylinder does not slide all the way down, file the high spots out of the block and reinstall the cylinder. Forcing the cylinder down may push the skirts in, causing the cylinder/piston to fail.

3. Once the cylinder and piston have been installed, rotate the crankshaft to make sure all the parts work freely together. Then, install the head.

4. Install the intake manifold. You must drill and tap the manifold if you want the bike to use the oil injection system, if equipped. The intake should exit off to the right side of the moped for Tomos, to the left on Puch's.

5. Install the exhaust system. Make sure the circlip is seated in the groove at the rear of the exhaust.

6. Install the choke lever on handlebar and install the choke cable.

7. Install the carburator.

8. The side cover of the carb may have to be cut to allow for the air filter. (Tomos only) Leave all metal that the footboard rubber mounts to in place. Cut out with a jigsaw.

9. Use a high quality synthetic two-cycle engine oil. Mix 4 oz. per gallon during the break-in period. Mix 2 1/2 oz/ per gallon after the break-in period, or use the oil injection system 50:1.
