Thanks guys.
I have access to any tooling. I've built many car race motors too. Unfortunatly my very good friend and machinist moved to Arizona but there's always shipping and I'll be there in a couple of weeks to visit him. I have a lathe and drill press in my garage. I have another friend that works at HAAS automation (CNC tooling) who has it all. Really the machine work isn't the hard or expensive part for me.
Also some of this 1.5mm can also be worked out some in the rods. I wonder what are the measurements on the rod specs for the KZ650 vs the CB. Anyone know if the journal diameters are the same? Lengths close?
Do you guys see any "I don't think so's that I might be over looking"?
Well i've been looking into a set of rods that are 1.5(min)mm to 2.5mm shorter as well for my '79 cb650....
Heck, i'd even go for 3mm shorter. Could omit the base gasket if i had to.
If you find anything that will work, PLEASE post it!!!
In about a month or so, i'll be getting a conn. rod from a cb550 to check against a cb650's rod..
Hoping that the big end is the same as the 650's, and shorter in center to center length..
Those KZ650 pistons look WAY more promising than the pistons I have.
But I am limited to 1 set of 65mm high comp. cb750 pistons, and a set of 750 DOHC (62mm) pistons.
Either set will need 1.5mm(min) shorter rods....and machining on the DOHC's(if they will accept that big of a valve releif)
Has anyone attempted to re-cut the big end on a set of connecting rods to shorten them?
mill off say 0.045 off the rods mating surfaces, re-bore close to size and hone out the last little bit?
I have toyed with the idea lately...
Having no access to a good hone for that job, I may pay to have it done if I cannot swap in shorter rods from another motor.
