I do see rims on ebay, but they are 5 or 6 spoke..mine are 3..are they compatable??..dave
No.
If you are looking at what I think you are, the wheels came off a CBR600 f2. It is possible to fit the rear to a CB-1 with just new spacers (but you need the sprocket and carrier) and you would get a wider tyre but the front rim, no way. You would need the whole CBR600 front end to make it work.
That guy is breaking someone's race bike, or quite heavily-customised street bike. Steer clear if unsure, as much of the parts won't fit a std. bike.
If you would like 6-spoke wheels and wider tyres, I will soon be doing that mod and will put up a how-to. I will use CBR400 wheels but I believe they are the same as CBR600 f3 wheels which you could get hold of easier.
If you are really stuck, in about a month I will be looking for ~£150+shipping for my used pair of wheels with good avon tyres, new rear bearings and used but useable front disc and rear sprocket. But I say again - shipping will be high, maybe verging on the ridiculous.
