Converting Z1000st to chain drive
Posted: Mon Oct 05, 2009 8:57 pm
Not been on here for a while.
I had a rush of blood to the head last week ,and decided it was time to drag the rotting hulk from under a sheet and start to rebuild it.
I then saw a gear cluster for a Z1H for sale on Ebay and ended up buying it. Now this is the fun bit ( or bloody stupid) ! I'm thinking of trying to fit the gear cluster into my ST bottom end . I split the crankcases tonight and found the first problem, output shaft bearing diameter on ST is 62mm approx, H bearing is approx 68mm. I will know dimensions better when I get a new battery for my verniers
It looks like there is enough meat in the crankcase to bore it out to the larger diameter.
I might not be seeing the bigger picture, and I was wondering if any of you more knowledgable folks, could tell me if I'm wasting my time and should just forget the idea ?
As it stands, it only owes me £12 and my time stripping it , so it's no big deal if I can't do it, I just thought it would be different.

when I removed the crankshaft, I noticed that one of the roller bearing locating pins was loose, looking closer at it there are 2 hairline cracks running from the pin hole and the hole is elongated. Have you seen this before, and what could have caused it ? I can only think that the bearing has tried to seize and it has tried to spin the outer housing of the bearing.
