I bought a brand new still in the box MR21 B01T yesterday and was wanting to know what size bearings are in this motor. I know they dont make this motor anymore but wasnt sure if you could still get some ceramics for it.

I like that engine, why do you want to change the bearing on the new well made engine?

I'm not going to right now just thought i would put some ceramics in it later on doww the road. Is this motor as bad a$$ as they say it is?

If you dont mind, how much did you pay for it.

is this the one with the white magnesium heatsink? If it is, its a great mill but tuning's a bitch!! I have 3 of these and i can tell you that tuning is different compared to the normal Ninja MR and GRP mills. This mill will run a little hotter than normal.
Also watch the heatsink as its softer than aluminium and will bend or even crack easily!
Lastly, you heard right about not being able to get a single part for this mill. The internals are totally different from the normal versions. I've been looking for the past 2 half years.
If the shop that sold you this has another, please let me know. Need another to break down for parts.

It is the one with the white magnesium head and i didnt buy it from a shop I bought it from a buddy of mine not sure where he got it from I know the guy he bought it from had like 4 or 5 brand new ones but I know they are all gone now. I hate to hear that it's a bitch to tune because I'm not that good of a tuner although I am getting better. I have had both the GRP and the JX ninja and you say it tunes like niether of these huh. I thought the grp was kinda hard to tune it seemed like it tuned kinda ass backwards for some reason. Yes i did know that you could not get parts anymore. not really sure why I bought it I just wanted it real bad for some reason

Well, maybe its the 'white' Mag heatsink that made you swing toward this mill? Looked really cool to have.
Anyway, if you decide to sell it let me know.
