I've never had a bike on a dyno in 44 years of riding so I can't say for certain; to me it seems the dyno is for high performance tuning or bragging rights. If you get so far off in your tuning that you need a dyno for a daily rider a good mechanic is probably a better investment.

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
