Ninja MR.21 A-series
First off, I tried really hard to find the motor sub forum with no luck so I sincerely apologize if this is in the wrong section. I'm looking for shimming information on this motor. There seems to be not much support help on line in the way of a digital manual etc...
How many and what size shim am i wanting to run in this motor? I run 30% nitro fuel.
It came stock with two .3mm shims installed which made it nice for break in since the compression was kind of low, but do I take a shim out or take them both out and install one of the .1mm shims the motor came with now?
Thanks for any help you could give guys, again I'm real sorry if this is in the wrong place.
