i plan on rebuilding one of my spare motors(never heard them run, but they turn over)...

anyways my questions...where do i get the lower end bearings, rings etc from..(z-1 dont have them?)

and id kinda like to bump compression up..these bikes have 8:1? or something right
 
Compression is 8.8 : 1. Bearings are available from Suzuki. Higher compression also creates more heat, and doesn't raise horsepower by very much.
 
An 1000G or 1100G engine fits and is lighter to boot.

Might even be cheaper if you find a good one, definitely easier than a rebuild.

You can do any displacement or compression you want with those, anything you can think of has been done before.

I had a 1000E engine in my last 750E, it felt like how Suzuki should have done it in the first place.
 
Isn't the 850 a roller bearing engine? No plain bearings to replace. A good stock rebuild is probably a better choice than trying to raise cr a bit. Degreeing the cams is a good idea for more oomph. If you skim the head for more compression, your cam timing will be off and you would need to degree them.

isnt the 1000 or 1100 a chain drive? is it possible to put the chain swing arm on my 850?

The 1000 comes in both flavors.

They 1100 eight valve engine is a shafty only.

Both fit the frame.
 
There is something about driveshaft parts you need or something, find someone who's done it for info. I've only done it on chain drive bikes.
 
If you are going to re-build anyway and spending the money on all of the gaskets and bits,
why not just find a 1000G engine and 1100 cylinder and pistons and make it an 1100? ;) (1050cc's anyway)
