No problem. If you have any issues, lemme know...I've futzed with them quite a bit (although not for a while). One thing is that on the 2 bikes I've used them on, I had to set the # of Cyl. to an incorrect setting to get the thing to read properly...no idea why (but dyno tach confirmed the setting were working).
got it all figured.I just did not know how to get inside menu.for reason you talking about.it was reading half of actual rpm's,was set at 4 cyl. I reset it to 2 and it is working fine.
great tach! i have had issues also, but once you get it dialed in, works awesome for the "old" bikes of float bowl era...lol
