Okay so... 61.5 bore, v-force reeds, 38mm flats, made a port from the intake ports to the crankcase, exhaust 195 degree, transfers 142 degree. The head design is toridial, 7mm band width, its 2mm squish now but I may tighten that up. Compression is supposed to be stock, but I still need to check that. I still need to do port work and add holes in the pistons and bring the piston skirt up. Wiseco pistons...the chambers came with the bike, not sure what they are but I won't be using them long.

Is there any info on how to identify who's chambers they my be? They don't really look like any ive seem on google, plus there on a gpz so maybe someone had them made...more just because I'm curious

Will I be able to check compression with no pipe,no carbs, and with a cold motor?

Okay, my squish is actually 3mm now that I've checked it...and I got 85 psi. now when I machine it down to a better squish, will I be able to 140psi? Is there some type of formula for that?

Or do I just get the squish right and leave it? I guess when the pipe come on the cylinder pressure will raise? I know when I did the lift the cylinder pressure was gonna drop.

For the squish to work at all, the clearance needs to be very close to .5mm.

Well that should bring my cylinder pressure up a tad..lol

Well ill get the cylinders machined, see where the psi ends up

Okay...so I did some changes, got rid of the think lift spacers and just put two base gaskets (copper) it lifts it 0.4mm and puts my squish at 0.3mm. I figure ill just port the rest. Better guys?...lol

.3mm might get you some piston to head contact. I don't like to go less than .035"

Here's a question, ex port width and radius. Should I just go by denco 90hp? Or is there a better way to go?
