Rear wheel swap.

I need your help....I blew out my rear wheel twice in four days on my 1978 kz650b model.the tire is fine but the tube has blown(got a new one and it blew again).and from what I've seen new spoke sets aren't cheap.I think it may be a spoke popping the tube....the spokes are original as far as I know...

But anyways...swapping out the rear wheel will be cheaper than new spokes and I want to go to a mag wheel anyways...what can I get to use with my stock swingarm and stock axle?I'd like a radial rear if possible.

I need to get this done by tomorrow night so time is of the essence.thanks!

Where spoke is protruding into wheel area and damaging tube, may grind down any excessive protrusion, and then use a layer or two of duck tape around the wheel inside the rim or go first class with a rubber rim strip (if not already using).



Good Luck!
