What is the cost on the new .12's? Are they all coming as a engine & pipe combo?

I've seen some racers blewup their mR21's.. but on mine i never had problems.. for now. i've tried ceramic bearings their good. murnan selln CB for it..

Does anyone know what the needle settings should be or at least a good starting point? My engine today kept bogging big time when i started it up. When the engine came up to temp it was fine but I pulled it off the track today at 270, it seemed to have the right smoke though,I can't tell yet. Still tryin to figure things out. Is it ok to run Ninjas this hot? some people say it is, dunno.

.21A

@Mike S.

What plug do you normally use with the .12 ninja engine? Talking about temperatures about 68F - 78F

Could someone tell what is the difference with A and w/o A version please.

I saw a stock MR12 run yesterday and I have a fealing all the locals will switch to this motor.

Which stores have em' already???

I heard that it could be with the LHS by next week.

Since there seems to be a tuned version of the .12, I'm going to hold off until I see what the price difference is between the two. Too bad the Ninja Web site doesn't have any info on it, to tell us what the differences are.

After the engine is broke in we run them around 230F.

They will be in stores this week.

With the rapidly changing weather we had yesterday, you would have had to adjust your carb settings a few times as the day went on. When you experience a bog before the engine reaches operating temperature, richen it up, run in until you get the temp up then adjust as needed.
270 is fine.

Sorry, explained it wrong.

Which plug do you use, when its outside about 68-78F?

Oh... ähm.. i got it
