I need to fix my left handle to put it more inwards
doesnt seem align with the right one when I ride

 

I rode my buddies cbr1000rr and my hands went numb in 11 minutes exactly. On the F4i my hands held up for closer to 40 minutes, that was the only reason I got the F4i and not an RR. Since then I put on a throttle lock and that little break every once in a while is all I need to keep my hands working for a long time.

My buddy with the RR now has a neck situation (not from the bike) and he has trouble riding at all from numb hands, so in addition to carpal tunnel, check out a chiropractor.

good luck.
