Damn another NEW motor.....hmmmm.....if it has the same bearings as the Mito I'm out.....
That stepped bearing in ceramic is pricey!

it has the regular 14.5 bearing, not the fancy offset type

Just picked up a 28-7 to replace my K4.6 in a Savage.

The clutchbell, bearings and washer from the K4.6 won't fit the Novarossi. It seems the crankshaft? is just a tiny bit bigger.

Any recommendation on where to get a new clutchbell and washers. Also, what gearing should I go with? I have an extended chasis.

Finally have my engine installed in an HPI savage.

I had to flip the carb to the other side, but now the exahuast pressure nipple is on the bottom side of the exhaust, is this okay?

I have 2 quarts of Byron Race 3000 plus a 1/2 gallon of break in fuel through my Roma and it just gets faster every time I run it. I did change the pipe today from a Losi RE10 to a Nova 41001 and 9886, what a difference. Its almost to fast on the top end, granted I was just running it up and down the road, and not a track. I am going to try to get to the closest track this week (its about 2hrs away) i know there are a lot of guys who run Novas there and can help me get a good race tune on it, but I think I am pretty close, on a high speed run up the road I am hitting about 240 to 250 degrees, no funny noises, and a faint but noticeable smoke trail. The plug still looks like new, when I pull it and put after run oil in there is a brownish tint around the threads and on the very bottom but it wipes off easily, no burnt spots and its not dripping fuel, just moist.

Now I am torn as to which motor to put in my race 8Ight-t, the Roma is excellent, but I wanted something different, I have a OS .21XZ-B Spec 3 ready to break in, but I might have to get another Nova. I was thinking a Vir-tus 7, Mito 7, or Bonito 7. I am leaning towards the Vir-tus, but any help is greatly appreciated, also any info on pipe and manifold choices would help, I am very new to nitro,and I have allot to learn.

Hmm still no comments on the Mantra....

I'm buying one. I'll report back once I have ran some fuel through it.

I ordered a Mantra also... excited to try something new...my elite 5 is still ripping but I'm ready to see what else is there

Looking forward to hear what you say about the Mantra

Novarossi released a new .21 7 port the Rolling

Any information on the novarossi karma?

Karma is based on the 21-4 from the early 2000s. Similiar to the bloody in the live range but with the better case and cooling head

So with a 19.2mm sleeve as also the Ielasi Tuned or the standard 19.5mm as in many models?

I normally run a Werks B6 Pro2, and I bought a Karma to try out since I had a 9901 pipe. It's a good engine for the money. Very mild engine. I don't care for the carb pinch bolt that it comes with, so I changed it out with the one from my worn out Keep Off 4.

Whats a good pipe for the roma .25

I am running a Losi RE10, i really like the set

Allot of people run the 9886 41001
