Any one have the part # for the GRP rod that fits the MR21 B01A?

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.

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
