Having just done a Freak and rejetted my 2004 790cc Speedmaster my seat of the pants Dyno says that is the best it has ever gone.

Now I think I should have a Dyno done to see if I am right.

We only have one Dyno in town and seeing that what I know about running Dynos could be written on a postage stamp with a paint brush, help is needed.

I was going to the guys workshop first to talk to him about what he does.

As a lot of you guys have been through the Dyno routine before, what questions should I ask him.

Please bear in mind folks I have only ever seen a Dyno on Youtube.

Can somebody tell me in laymans terms what happens exactly.
