is everything good with the switch? bypass it and get 12v to it to see if it works. i bet it does


if your rear brake actuates the brake light, there's absolutely nothing interfering with it like the turn signals...

 

hello, could you tell me how to install the RPM of the trail tech vapo computer on your cbr f2 if the motorcycle has two ignition coils thank you I need help please.

 

Hi ,never done one of these before and I'm sure someone will correct me if wrong, but don't think it will matter which coil as its wasted spark, so would wrap sensor round #1 cylinder spark lead (5 or 6 times) and adjust display as laid out in the Vapor Manual, for 4 stroke, not sure how far the RPM goes up to on your instrument, but remember the bike registers 15000rpm
