There are front motor mount adapters you can buy (or make if you're handy like that) which will solve that problem.
Only other problem is the front fender. The hanger bracket off your forks will fail in no time (as it will with the back fender). Should that happen, with only 1 support bracket on the back of the fender and connected to the axle, the fender could spin around under your wheel and over the high side you'll go.
Otherwise I think a shift kit would be no problem. Just realize though, once you go with a shift kit you'll be spoiled for life...
That's the bike. I actually did hear about peoples fenders failing and that's why I didn't even bother trying to re-enforce them and just took them off all together. I'm also using a SBP front tube adapter if that helps.
