Greeting all,

I am looking for a tachometer/rpm gauge (I know they are the same thing) to mount on my CR85. I am hoping it will help with my corner exits and staying inside the power band, since it will give me a visual representation of it (the powerband).
Lately I have been having issues on corner exit. When I roll on the throttle I will have either not down shifted enough or rolled off the throttle a little too much so that when I roll on, the bike bogs down for a few seconds, killing my drive and allowing me to get passed.

I know there are technique/ riding skills ways to solve this problem, which I am working on. But I think a tach would be a good piece of gear to have on the bike, to know what's going on down there between my legs. :anim_peep:

Any toughts/ideas?

There was an old thread regarding this that was not very search friendly. It can be seen here: http://www.supermotojunkie.com/showthread.php?9929-Tach-setup-for-cr80&highlight=tach

It's a little old and was in reference to a CR80.

It mentioned the below linked products. Anyone have experience with these?

I have been looking into these for my YZ too.
However, I figured those $50 would be better spent on a track day... :lol:

Not to rain on the concept, but I think putting a tach on it would probably make things worse. You'll be watching a tach instead of focusing on your line...

Just my 2cents.

I agree. I put a lap timer on my bike and looked at it twice and both times I missed my brake marker. I then started looking at it only off the track and after two times to the track it sits in a box in my garage.

Anyone know what the functional redline is on the CR85? From what I understand, 2 strokes don't have a true redline right?

This is another reason I would like tach, to know if I am shifting at the proper time, or if I have more rpms I could use before shifting.

ride it by feel. the redline is when it stops pulling and you wish you had another gear.
I guess I am afraid I am going to blow my motor by wringing it out too much. I have heard of guys doing blowing it up with their 2 strokes due to lack of a rev limiter.

a tach would be pointless. you just need to ride the bike more and get a feel for it. practice makes perfect.

and people blow up there 2 stroke from lack of lubrication, not redlining it.
