Parts compatability with the MR Ninjas for the parts you need are hard to find but not impossible. Look for conrods for the GRP .21, Tecnopower .21, Ascendency g5 .21 and you should be good to go.

hope this helps.

We have a lot of rods in stock.

Word! Thanks Jason. I finished breaking in my Ascendency g5 this weekend, and it ran like a scalded dog. 3/4 of a gallon to break it in to do it right, but it made me miss my old GRP/MR Ninja very much, as I love the power band of the italian motors.

Left postivie feedback on A-Main about the engine, hope it helps others when selecting their engines. :cool:

I just broke out my Mr.28 I bought back in '06
Believe it or not I never ran it until 2 weeks ago
My question is, if anyone can answer. Today I put
A picco plug in it and it leaks a little. Did I just ruin
The button running that plug?

I had 2 ninja plugs which are now shot. Threw in the Picco noticed it leaks

but still ran really well. Not sure if I'll ruin the motor running with the plug

leaking. I can't find ninja plugs anymore, and if I did will they seat right.

What is a pipe for this motor MR .21 b01a?

2053 i see but not sure where to find one. what is close

os 2050 or 2060?

I know it's a novarossi motor would a nova pipe work better?

The Ninja 2053 is the best pipe for that motor or if you can get a Dynamite 053 for it. Loved how smooth this motor was!

I could always get os p3 plugs any where I went so I put it in and tighten & loosen it 3 or 4 times and it seated in and sealed. the new ninja plug is an os p3 cause it is os based.
