Title: Squish and Band Width Check
Post by: Bio86 on June 01, 2014, 06:59:39 PM

I'm messing with a motor out of an 88 I picked up, has a 73mm piston stock cylinder with what says a 22cc dome. Using .062 solder getting .035" at the cylinder wall with a width of like .525" on the dome side.  Does that seem correct?  I have no clue what the porting is and haven't degreed one before to know where it's at.  Just looking for some guidance there, afraid to throw fuel in it and have it detonating real bad right off the bat.   Haven't done a compression check yet.

Any thoughts?

Ended up throwing it together.  It has 210psi with non-seated rings.. that's 110-112 fuel territory correct?

Has your dome been machined for your bore size?

Yeah it has, the flat surface lined up nice with the top cylinder face around the bore.
