CAST ALUMINUM PRIMARY COVERS
TO FIT "KR, XR750 MODELS & SPORTSTERS
Manufactured in 2 different widths to fit both narrow and wide clutches
These covers are authentic reproductions of the cast aluminum primary covers that were used on the "KR" racers in the 1950's and 60's.
The patterns were made from data gathered using our computer controlled coordinate measuring machine.
They are sand cast in 361 aluminum alloy and heat treated to a T6 condition for maximum strength.
These castings are then accurately machined on our CNC machining centers to a standard that is unequaled in today's repro parts market.
The inspection covers feature re-useable O'rings for leak proof sealing.
The mounting holes are machined with only 1/64" clearance.
AND THEY ALL FIT
The gasket surface is precision machined flat. NOT SANDED
Comes with all mounting hardware and can be ordered with option for electric crankshaft starting.
Both width covers are in stock and ready to ship
