Hi all
i haver just purchased a nsr 250 r mc 21 the guy that owned it before me said the standard pgm failed so he had a hrc pgm 4 wired into the loom. everything works except the rev counter could this be beacause of the pgm? he could not tell me if the rev counter worked before so maybe a faulty rev counter? your veiws on the modification would be greatly appreciated.

Thanks
