Stock Phazer cylinder dia.

[Heveron]

I need to know the stock cylinder diameter for a 1997 Phazer, Mountain Lite. New top end might be required since cylinder compression was only 75lbs on both cylinders.

Thank you for this information.

best thing to do is open up the motor first and see what you have and then go from there ...... check for damage and clearances and ring end gaps if pistons are still good
