Hi this is Kenny, can I get the mileage on your bike, and has this unit been sitting or have you been using it all along ?

The regulator/rectifier is there basically to convert AC voltage into DC voltage, keep your battery charged, however you need to make sure that you start out with a good battery, do you have access to a volt meter, (multi-meter) and want about checking the compression on this engine ? I would like for you to check the compression really before we move on, just make sure that we are not dealing with an engine problem.

Thanks

Kenny
