CYLINDER SQUISH BAND CLEARANCE CHECK

A proper squish clearance can give your motor 10% more power. Most aftermarket cylinder kits are not made to this close tolerance of 0.6-0.8mm proper piston clearance. We check the squish band clearance and usually have to close the gap from .18 -.13mm down to .8mm gap for proper squish band function to work properly.

How to change piston / top end rebuild 2002-2007 Honda Cr 250
Join the FREZ PRODUCTIONS Facebook site! https://www.facebook.com/frezproductions I`ve got many nice comments for making the "Honda Cr 125 piston / top end rebuild" movie. In this movie, I show in good detail how to chance the piston on your two stroke Honda Cr 125. A similar movie for the Honda Cr250 would be nice, and that's what I have made. Hope you like it! The bike used in this movie is a 2007 Honda Cr250. Always use the right manual for your bike! The 2002-2007 Honda Cr250 bikes are very much alike but there are some changes. That's why the right manual for your year is important. Good luck! Frez Productions
