Tuning MR12T10A
 

I'm having problems tuning this engine. Does anyone know the factory setting's?

I can check when I get home on mine and let you know. What is the engine doing or not doing?

Hi,
I have just bought a second hand Ninja MR.12 T01A and was wondering what plug I should run with is as it came with a 5,6 and 7. I asked at my LHS an he said the 5 was too hot to run in it. Thanks

I've run 5's in mine since I got it with little problem. I know quite a few people run 7's though, which the motor seems to like once it's tuned.

ninja 12 jx
 

i believe that ninja is releaing the jx series on road engines is this true or not:confused:

I heard that as well and look like it is going to be O.S. Speed base

Ive been running a MR-B01A in an MBX5T this season and it has suffered from a lack of bottom end. I have used a 2050 and 9853 pipe on it. I switched to 1.1 spings and it helped a little. This past weekend i tried a JP-1 pipe and it really came alive. It definitly lowered the max rpm but im ok with that for now. I ran a 10 minute heat and still had some fuel in the tank without a pit stop. I have heard that the JP series pipes are fuel hogs. is there a better low end pipe i should be using?

thanks, Steve

Mr. BM, what do you need?

Hi Jay, I'm looking for a piston and liner for my MRT 12 but i don't like my chances.:cry::cry:
I thought someone might know of a shop that has some old stock but no such luck:cry::cry:
Looks like i'll have to run the Sirio EVO4 and the XXX and put the GRP on the shelf in the shed.:sneaky::sneaky:
