They are a great around town bike.

Can't say they handle 70+ mph freeways though - only rode one in 55 mph years.

I HAD ONE, IT WOULD DO 70. liked it  a bunch, if the right one came along id own another.  but its def a very small light bike, but reliable as hell.

Ok thx all!

That looks like a great deal for 1K.

Ok, guy said he'll take $700. One pipe has a hole near the low end of header, spokes are clean but rims have spot rust. Frame looks good just surface rust under seat. Chain is toast. Starts right up but he just did the top end not seals. If it runs the center seal is probably ok? Said it had a cracked piston so I'm thinking air leak.
How hard are the cranks to split and get back together straight and true? I don't wanna pay for another crank job if I can get the stuff to do it for the same price. I have a steady hand and a pretty sharp attention to detail so why wouldn't an old dog be able to learn this trick? Can the outer seals really come out with cases together? Found the seals on eBay for under $40. There are pics of a basic setup for doing one of these cranks on suzuki2strokes.com, looks pretty straightforward. Is it?

Cranks have to be split carefully , and is actually quite a skilled job ,
a well rebuilt crank is completely different to one which has a bit of runout .
The outer bearings and seals are an easy bench job.
The main tools that are needed are a good hydraulic press and hide/ copper mallets, then V blocks ,centres  and a couple of dial gauges.
At the finish you are looking for minimal runout, under a couple of thou.
I think it's more economical to get the job done by someone who does in every day without causing further damage and problems.
