Would the GB vibrate a lot?
The engine is essentially a sleeved-down version with the same stroke as the XL600R enduro bike and it has a gear driven counterbalancer.
I would like to have one and do some performance mods to it;remove the stock engine and exhaust,then build a hi-perf. XL600R engine for it while keeping the same stock 75mm stroke as the XL600/GB500.
The member here 'dunk' has an XL600R that he's done quite an extensive rebuild/mods to in a thread.
I imagine they're aren't many owners that would do this because it would take away from it's collector value of the GB500,but I would love to.
It would be quite a sweet thumper with the mods.
I imagine there's a used GB500 somewhere..
that had been ridden(rather than sitting)as a normal bike, or one that was in an accident that could be bought for less $, then a person could purchase it for less $ and fix it up/do what they want with it. The one I describe may take a while to locate.
