I just installed my Trail Tech Vapor last night....so nice! Especially since it's hard wired in and lights up when the DS switch is on. Do any of you guys know what the Rev Limiter is set at on our bikes? I wanted to set the shift lights but havn't a clue as to what RPM's to set them at???????????????

Not positive, but I believe that the limiter is at or near 8500 rpm. However, I would speculate that peak power is slightly below that rpm. I guess if I had a tach I could tell you, as I can hit the darn limiter when I do something stupid on the MX track.

If you have one of the 'rev' boxes that was available for the 650R, I think that those raised the limiter to 9100 rpm.

Rev boxes don't get you much unless you have at least a cam and exhaust. They probably do more harm than good by wearing out your motor faster.

Stock engine doesn't make much power past 7500 RPM. Get a cam and it will go to the rev limiter.

Be carful when riding. If you are looking at shift lights, you are probably not looking for obstacles and corners.

Between the Vapor and the GPS i no longer need to look up when riding. :p

I'm setting the shift light is only because #1 it's there and #2 for long fire roads where I run out of gearing and don't want to bounce of the limiter.......shift when it stops pulling the rest of the time :thumbsup:

I've programed my shift point indicators at
First: 6400 rpm (a little before Max power)
Second: 7200 rpm (a little before rev limiter)

My heavily tuned 650's power drops off after 7500rpm so thats a suitable limit to set it at. The CDI starts to kill the power at this point.
