Is the P/S totally wrecked, or can you get by with a re-sizing? RayAracing is one of the best in the biz to bring P/S back to life. All you would need is to pick up a connecting rod and wrist pin.

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.

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.

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?

Ruin? Depends on your definition, but now you're limited to what plugs you can run in it. What plug(s) were previously used?

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.

there is a tapper difference in the ninja plugs, on the .21 that I had I run os p3 plugs in it the tapper is off a little bit but you don't want to try a bunch of different types of plugs in it. 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.
