Hi AussiXS11G. Great looking conversion and maybe one day......
For now and one reason why I brought the XS1100 was because of the shaft drive. No more messy chains and for the way I will ride the bike, the arguments of getting power to the ground and twisting etc won't come into play. The only mod I've made is revert to an XS750 diff to drop the revs.
I have undertaking other engine mods but they were mainly because I stripped the engine down to basics and took advantage of not having to do that once day down the road. just as well as I did as third gear was a little loose so I made a new bush and shim for it, being I think the main beneficial gear.
But like I said earlier, great conversion.
Regards
