    So my neighbor has this bike, a 125cc, and hes having a problem with the battery draining in 2 days if he doesnt ride it. Replaced the battery twice, same issue. I told him there has to be something draining it somewhere. He took it to a guy who also couldnt find the problem.

    I told him with all the computers and crap on there it would probably be a pain to try and find exactly where its draining and it would be easier to just install a battery switch. Problem is, I cant find a switch rated for more than 10A and Im not sure that is enough to use as a battery switch.

    I have a 16A rocker switch that I used for my 69 T100 as my ignition switch (only wired up to the transistor box for the ignition) until I got my keyed ignition switch replaced.

    Does anyone have any idea what kind of amperage a bike like this would pull?
