you can order it right from the website

Uriah do you still stock modified parts for the novarossi ll3 and also what pipe do you recomend. Application the miami home stead track. Thanks the look of the new site is great.

How often should ceramic bearings replaced? Do they last longer than steel?

Any dyno results from the RB Alpha's? THX from Houston.

duno about the dyno !
But i seen it at the Sugar Bowl sunday and it sure spooled up very Quick!
looked superfast to me and a sound of it's own!
later
Jeff E.
I'm sure Uriah will speak for it soon!

I would like to see some dyno results too.....if you got em you might as well show em... I have yet to see any real dyno results from a Murman Engine.... If you got the power lets see it !!!!!!

Hi. I do not have parts for the LL3 anymore. I recommend the Novarossi 2630 for that engine.

Hi. Ceramic bearings last longer than steel if they are good quality bearings. They should be replaced when they start feel gritty, or have too much lateral play. You can often hear when the bearings are going bad. You will hear a rattling metallic sound.

Here you go.

The #'s may be hard to read so they are as follows

Stock Alpha
HP= 2.30
Torque = 74.33 Oz in

Modified Alpha
HP = 2.44
Torque = 81.38 Oz in


The Alpha can be made faster, but the tendency is for the aluminum sleeve to break, and ease of tune goes away. This has shown to be a good compromise between power, and reliability on the modified Xenon Alpha.

Not sure why the images are not showing up too well. I will try again. Here is the Murnan Modified 35+21 vs Stock 35+21 graph.

Stock 35+21
HP = 2.50
Tq = 79.18


MM35+21
HP = 2.85
Tq = 81.38

The images were too big. These are easier to see.

Stock Alpha
HP= 2.30

Modified Alpha

Stock 35+21

MM35+21

Hey Grinder can you post results for the Picco P9R stock and Modded?

I know your results are not for show but I can't afford either of the above two engines so I'm just curious.

Hey Uriah,

I was wondering if you know this one. I was looking at the part numbers for the piston, sleeve and rod for the N12LS3 as part number 08672. I'm looking to get a replacement set for my MAX SL3 and Max lists it as MX08672. Do you know if they are indeed the same? I know the bore and stroke of the motor are the same. I know the sleeve for the the max motor is longer than the typical NS series motors when Novarossi changed the crankcase. Was this the case also with the N12LS3 motors? I'm interested in buying it if it will work. I know the rod is the standard 07601 rod.

What is the best way to change bearings? Are there any tools available to help?
