Are you sure you want to get that involved? I dont know of anyone making a weld on hard tail for that wide of a wheel. I cant remember if it is a 5.5" or 6" wheel. So you would either have to build your own or have it made. A jackshaft or idler box would have to be manufactured. I think it is abou 3/4" farther out on the sprockets. Which would work well in figureing out the gear ratios ( which I already have done). fzr 1000 has a large rear sprocket. The botttom of the neck post would need to be turned down to use a stock set of xs tappered timkin bearings for the forks. From there the bike would have to be owner designed. I was going to go with foot hydrolic clutch/ tank shift, with 3 gal harley davidson fl tanks, car eye dash with yamaha speedo, vintage 50's-60's stock sportster solo seat on honda 70 shocks, forward controls, Stock late 50,s fl headlight 6" risers and stock 75 650 western bars.
