so ...
8.1" = 205.740 mm half the stroke = 37mm Cr 500 rod = 144mm MTC-K1327H compression height = 24.8793 205.740 mm deck -205.8793 assembled height +0.1393 mm or 0.0054" Think I'm close enough to worry it into spec with head and base gaskets ? :-)
8.1" is the distance frome crank centerline to top of the XS650 cylinder
The 1/2 kit price is $255.73 as these pistons were originally meant for a big arsed 1300+cc over bore of the Z1/KZ 903/1015
I think that beats the hell out of $400/pr don't you ?
Then again it took me countless hours to track down the information on the interwebz and on the phone
I am not soon going to forget that brain dead 20's something at Wiseco that told me the compression height was "proprietary"
Or Ross and J&E both wanting minimum orders of 8
Or the nameless ID10T that kept telling me " they have different pin diameters it won't work " no matter how many times I told him it was a CR500 rod with a different small end diameter " That's a two stroke rod " , well yeah , sooooo ...
So my machinist answers the email with the dimensions with " And what was so hard about that ?"
I get him on the phone and the voice of reason tells me " Dennis , not a whole lot of people think like you do . You're just going to have to accept that fact and learn to live with it . I have "
Get it from Mike or do it yourself the price difference isn't enough to quibble about . Any real savings will be from your machine shop of choice and or your assembling the pieces . I will stress for the novice that these discussions are all hypothetical until the assembly is trial fitted and the dimensions/clearances verified .
many thanks to Brett ,Greg , Dick , Bubba , LarryC , APE , Cliff @ MTC and Google Calc for the conversions .
