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.

(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

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





EXPANSION CHAMBER VISUALLY EXPLAINED
(EXACT English TRANSLATIONS have been uploaded to Closed Captions for VIEWERS interested in accurate translation in THEIR LANGUAGE -thanks). I am continually trying to get the perfect version of how an expansion chamber piper works. I may make a few of these little videos until I get the right one. This one looks rough and I may not keep it up on the youtube. I hate to practice or prepare for a video too much, because it ruins the spontaineity. I need to find just the right words to explain this expansion chamber effect.RH
