Re: what did you do to your motor bike today?
I put a grip shifter on a few days ago as a clutch. =) Much better than the handle clutch that had to be mounted way up on the cruiser bars and doesn't work on my new straight bars. And it keeps the handlebars clean! It would actually be tempting to use a continuous-style thumb shifter as a throttle for cruising around, but I like my twist throttle for now. =)
Tonights projects; try to set up a choke control with a thumb shifter. =)
