What do you mean, you tune by ear?

On a my bike is it ok to cruise in say 3rd or 4th at 5k RPM (redline 11k) or should I keep it lower around 3k RPM? Hope that made sense to everyone. Thanks

Without knowing all the details, I think a general rule to use:

keep the RPMs between 20-80 percent of your redline. (for 9,000 redline ==> between 1,800-7,200 rpms, I'd use >< 2k - 7k rpms for easy to remember numbers)
regular cruising I would think about 50% of the redline. (for 9,000 redline ==> about 4,500 rpms)

This will help keep the engine from lugging (too low rpms) or being too stressed (too high rpms)

This is similar to what Wrider said but in more words.

I'd like to see him try that with a desmo

Back in the day, a friend tuned my Kawi two stroke triple by ear. When I took it to the shop a couple days later, they said it was right on the money...

Good to know Scooter12.....now what does that have to do with the thread topic?
