I was reading over my manual for this kit and it doesnt give a specific squish recommendation. It’s the newer design with the fancy head and it came with one metal base gasket (0.25mm) and one copper head gasket (0.5mm). When I mocked the piston and bore up today I slapped on a 2mm+ diameter piece of solder across the wrist pin. Dry fitting both gaskets did not compress the solder at all… I removed the copper gasket and measured again. This time it was 1.5mm. Removing all gaskets net around a 1.25 overall squish. I’ve never mocked up a squish test and have it essentially require no gaskets to meet the normal 1-1.2mm squish band. Im more used to my Minarelli and Dio motors requiring 0.75-0.95.
I do not have a timing wheel or want to mess with port timings, I figured the Polini would be good out of the box but I’m leaning towards it needing some work. Should I just use it as is with zero gaskets and Hondabond (3bond) both the base and head. Or do I get the head/bore machined down 0.25-0.5mm and run the base and head gaskets. Another thing of note is that the copper gasket doesnt even fit the circumference of the head even that great. Overall not too impressed with the quality.
