I thought i found a good deal block and pistons but after doing a search i found the info about mixing blocks. Im back to plan A
That's a nice bike. How's that baby handle in the snow?
If you want to mate two different cases it's not a big deal. It would be to your advantage to stud the mains ($120.00) and you may as well plan on running bigger bearings while your at it (there is no other option). If the cases are mismatched your only option is to bore them. It's not a big deal.
A set of little kawi mains are $90.00, a set of clevite H series are $90.00 (because you need two sets).
The kawi's are .058 thick. It's a weak stab at a TM (tri-metal) and complete bullshit for a high rpm engine, #2,3 and 4 are wider than 1 and 5. For some stupid reason kawi chose to run full groved shells on all 5 journals plus cross-drill every crankpin? Fucken idiots.
#2 & 4 main journals are the only 2 which need 1/2 grooved shells in the lower case. #2 main feeds rod 1&2, #4 main feeds rods 3&4, both main pins are crossdrilled.
#1,3 and 5 are nothing more than big stupid bushings that require minimal oil.
The replacements that I would recommend are Mahle .075 TM. Your other option is an old Vandervell shell # that has been reserected by C&A, which are a BM bearing (aluminum silicon) .095s, and a $75.00 set.
Either one is fine.
Sorry if I offended with that prior post.
