just been looking at my dismantled,semi polished(im workin on it,just waitin for new fingertips to grow back)cases, and if Kawasaki managed to get 4x 6306 crank bearings into 'standard cases',im a godd**n chinaman.anybody got any thoughts? the cases in the feature dont look any wider, so the only conclussion i can arrive at is that they had thinner width bearings in order to double up,but unless that increased the total bearings surface area,(more durable,more area to spread the load but also increased friction)i cant see the point unless they were suffering mains failures.
this should be good....

If its the same Dave King from Vegas.  My uncle has been a friend for 30 years.  Owned a flight service to the grand canyon for years.  Uncle used to tell me to meet him as he was into bikes.   Never met the guy ever.   Fast forward to now.  A buddy met him on street bikes one day.  Went to his house to see his dirtbike collection.   Guess he has a s**tload of rare bikes.   And reportedly a few Kaws....

thankyou! yes, that is the one! i bought it last november. i have always wanted a 500 motocross, road legal. it started with me buying my mates 1992 bike in bits which he had for 10 years. that was 'going' to be my motard then i seen this bike on the bay. i had to have it. i didnt know anything about the bike until i started searching on this site. for some reason the powervalves have been pinned fully open which leads me to believe i only have bits of thorpes engine, it goes like a rocket ship tho! i now have nearly 4 kx5's! once i start i cant stop! i have fully rebuilt the 92 engine, replacing every worn part in the process, not cheap! but its the way to go if u want reliability. this is my spare engine. this site has been a wealth of knowledge for which i am very thankful! i have been a member since november but have not posted til now (reading and learning b4 i open my mouth)!. the bike is now black, everything is new. i will be taking it back to the brittish hillclimb scene at some point in the future, i cant wait! demographic, u know about this machine! i am a geordie, we should meet halfway some time!
