MYTH #1... The 860 (800 cat) piston skirts are too thin...
A) This piston is designed to run at .0045"-.005" clearances...if you install them at .006" or bigger (like most do) they will fail early...SHR sets them at the proper .005"...record SHR860 mileage is OVER 5000 miles on the same pistons.
MYTH #2... The 880 bore is too big and the cylinder walls are paper thin...
Lets start with a little math...
what is 1 mm in thousandths? .040"
what is half of 1 mm? .020"
what would the cylinder wall need to be bored to change bore diameter .020"? .010"
A) a .010" thinner wall thickness DOES NOT make it ANY less reliable...period.
MYTH #3...you cant weld the aluminum SKI-DOO cylinder due to some coating???
A) this is easy...PROVE IT!! ...while we are at it, I have some SLICK 50 for sale.
This post is for your information...ALOT of DIS information out there...BJ
BTW, SHR can/will/does FIX all brands of BBs out there...just saying.
