If its a rebuildable motor, you can cut the comm (which changes the timing), change brushes, springs, hone out the bushings, change the angle of the brushes.
Lots of stuff. But you need alot of time, and a dyno to know if the changes you are making will work for you.

is how we can tune a modified brushed motor but how can we tune a stock brushed motor (like hpi saturn )?

also turn to more rpm first !
when find spring to support torque !
the motor need respond torque & rpm very fast & not heat , will good !

Cutting a comm changes the timing? That's a new one I haven't heard...
Google Big Jims Black Book.....I think its still hosted on hobbytalk. You will find plenty of info on tuning brushed motors....there is plenty of tuning.
For a dyno, look for a TurboDyno 45......can't find one of those, a Fantom Facts Machine can work, as can a Robitronic....

"TIMING CHANGES WITH CUTS
Another thing you have to keep in mind when cutting your comm. is that as the diameter of your commutator gets smaller it will actually advance the timing of your motor. Chad Phillips of Team Trinity says that for every 0.005" of material you remove from a commutator the timing will advance by about 1°. With this being said, if you skim your motor between runs your timing could greatly increase during a single event and you may dump during the main, so keep this calculation in mind and make the proper adjustments to keep everything in check.

While I love chad.....I'll go ahead and call BS on that.....that would effectively make larger comm likes the KR or the new 10mm comm we are using in crawling have retarded timing......trinity was always famous for their timed brushes....another bleh claim....of course by saying cut .005 off and you gain timing, you sure would go through arms a lot faster....
Smaller comm produces more RPM, but its not a timing effect that I have ever heard of or been taught...
