Well Im right now looking to getting a Trail Tech Vapor Computer which will tell me the rpm, speed and temp. The stock speedo and tach have been done away w/ since I have a '06 gsxr front end installed. Does anyone have any experience w/ the Vapor gauges, good or bad?

I've never used one personally (although I do have an Acewell on my GR). But I've heard of plenty of good reviews. I think the biggest issue was the initial setup - sensor for the speedo, tach, wiring, etc.

Using one on the pig. my goped gtr40. every time you add a sensor, you must reset it. (( easy to do. reset button on rear)
