alright so i want one of them tiny tachs biggest downside i can see from reading the specs is that the refresh rate is 2.5s. Has anyone used one, and is that a satisfactory refresh rate? i use a digital speedo which isnt super fast on the refresh and it seems fine, but i dunno exactly what its rate is so i cant quite compare.
secondly, after reading the list of models they have, i assume i want the first one (1 cylinder 2 stroke). correct?
and finally, this is a bit different of a question. i want this thing so i can get exact rpm figures to use for, eventually, calculating dimensions for an expansion pipe. my first guinea pig bike is my friend's puch. he has a biturbo. this seems obvious, but i assume i should take rpm readings with the properly tuned stock pipe as opposed to the properly tuned biturbo, yes? thanks,
