FYI
Go to "Tractor Supply" and look at the size 50 chain. Its the same size as a motorcycle 530 . The tractor supply chains come in 10 foot lengths for about $20.oo
, and they last a lone time on heavy equipment or motorcycles. They have master links , half links , and sprockets of all sizes . All their sprockets have a two inch hole in them so you need to cut them to fit your application.
The size 40 is the same as the bike industry's 428. If you want "HEAVY DUTY" check out the size 60 chains !
I use the spray white grease on my heavy equipment and it stays on good , but have used the spray wax made for chains with good success too .
I haft to wonder ??? Why would anyone want a chain when the belts are so much more trouble free and cleaner ??? The Kawasaki pulleys will gear the LS650's up as much as needed even too much for stock engines. Some times I'd like to go lower geared a little (parades and such) for ultra slow speeds.
