A dealer near me is offering free dyno runs. I always thought dynos cost a pretty penny.

I'm going to do it, because I've been thinking about it for a while, and most people here in the forum say it does wonders for their ride.

Anything I should be looking for?

I'm sure it's a lure, but what the hell, it's free and a good excuse to ride.

 

It's not a tuning dyno. It will be a free pass on the dyno to tell you what the tq and hp is.

 

Yeah.. that. At rally's like Daytona, Wildwood, Myrtle Beach, etc people bring their mobile dyno units and let guys put their bikes on them for a run, then will give you recommendations on tuning and such, but won't actually do the tunes.

 

Yeah, it's a lure alright. They will let you run your bike and then tell you, "for $100 per hour we can adjust your tune and get those numbers even better"!

 

Do it - at least you'll have your base numbers

 

I'd say skip it unless you need it for a couple reasons - first, dynos can cause excessive wear to your tires at an alarming rate and in an un-natural fashion (a flat center strip where the wheels meet the rollers). Even tire manufacturers recommend against it - see section 10 at this link. Second, subjecting your engine to the range of rpms that a dyno needs to see there is always a chance that a dumb dyno operator could blow your engine - especially if it has any issues you don't know about like a bad cam tensioner thats about to go. I'm not saying dyno testing is the worst thing in the world but why chance it if you don't need to? I guess the litmus test for me would be asking the operator who pays if something goes wrong.

 

Sure as hell does say that (about the severe tire wear). I did not know that. I guess I'll skip it. I just put on a Commander II. Thanks for a great tip!

 

Unless it was a professional tuning your bike I would just skip it.
