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.

OPENING THE INTAKE PORTS BY 10%
I am enlarging the aluminum crankase intake ports by 10% to see if it will increase performance at FULL POWER.





(3)- Mating the 54mm cylinder to Stroker Crank
This is the tricky part of compressing both rings while trying to manouver a 4 kilo iron cylinder above them. It does not help with my slightly stiff, 50 year old hands. It should be a snap for you young guys. RH





DIO MONSTER RACING PISTON PROBLEMS
54MM piston is too tall and will hit crankshaft. The skirts must be shaved to supply clearance for full piston/crank rotation.





(1)- Two Stroke Piston Problems
Piston failure happens alot. Knowing what to look for in the damaged parts can tell you Exactly what went wrong and how to correct it for the future. This 3 part series explains my take on why and how pistons fail in two stroke motorcycles.

Blueprint 106 - Cylinder Bore Inspection
We're close to the end of the 100-level series. In this video I show you how to measure the cylinder bores using 2 different tools. I compare the results and illustrate what to look for to determine whether or not your engine is in-spec. The block I'm using is a 6-bolt turbo 4g63 from early '92. It has 150,000 miles and this video also serves as a testimony for the durability of Mitsubishi's cast-iron solid-decked Sirius I engines. This engine will be cut for a new set of pistons, so these measurements are needed to determine what size pistons I need to get. .030" is as far overbored as you should ever take a 4g63. Boring larger than that will take too much off the side clearances between the cylinder walls and result in compromised strength from hot spots. The only time you'll ever need to cut a bigger hole is when an imperfection prevents you from using the pistons you have, or if you're changing to a larger piston. If you cut the block to its service limit, you have no room to fix an imperfection should one develop... so it's best to cut as little as you can get away with. Boring a cylinder .020" over does not significantly increase its displacement.

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
