Note:

1.  Make sure your engine has a 69mm tall cylinder before ordering

2. We recommend you test fit the cylinder. The best way to do this is to initially test fit the cylinder without the piston installed at all.

3. Test fit the piston WITHOUT the rings on the connecting rod with the cylinder installed and check the deck height to make sure the piston does not stick out of the cylinder at top dead center.

4.  Double check everything with this advanced engine build TECH LINK:
