IF you do find any info would appreciate sharing. I just pick up my NEW RL yesterday. The kickstarter lever seems to be a bit worn out as it hits the foot peg on the way down. I going to work on that today.
My guess on the headlight is you may well need 6 volt products. I have a TS185 and it is 6 volt too.
Seems like there are enough RL's out there with folks who need help to start a folder or thread.
I have collect a lot of files on the RL.
