Grinder,

I recently bought the capricorn off-road engine from you. I sent 2 emails but never got a reply. Anyways, the engine did not come with any instructions. So all i need is the factory needle setting for the engine.

Thanks.

The low speed needle should be 6 turns out, and the top needle should be about 5.5 - 6 turns out from the factory. This makes both needles about flush with their housings. ;)

The type of modifications done to the MM+4 are done to add power, but at the least expense of fuel consumption. I have increased the power as much as possible while still running at least 11 minutes in buggy in all conditions. The MM+4 does not have ceramic bearings, although they are an option. The engine is more powerful than stock with almost as good of fuel mileage as the stock engine. I think any more power in a buggy will just hurt laptimes with excessive wheelspin.;)

Marcus-Things are good. The racing scene up here in Charlotte is crazy. I actually have to choose what races to run because there are too many too attend. I could feasibly race 4 times a week up here with the East coast nitro series, NC state series, The Farm, Carolinas, Nitro Valley, and Overcash all less than an hour from the house. I don't know whether to sh!t or wind my wrist watch! I love it. I can't wait for the Battle. You gonna let my squeeze on that Plus 4 when you get there?

4 times?

why so little? :lol:

:rolleyes: Bigtimers...

grinder are you coming to dalton this sunday?if so can you do any mods to a speed to increase run time i like the smooth power but not to happy with run times im getting.

Hi. Yes, I will be in Dalton Sunday morning for the race. I can give that engine better fuel mileage. See you Sunday. I will probably be at the track Friday, or Saturday to practice, and test things too. :nod:

JP- Hey man glad to hear all is well up there. I'm sure we can switch rides for a bit as I want to drive your H9. But most likely after I win the A. Hope you are sharpening up those 8th scale skills for next weekend.

Crash- Just in case you forgot I hate you! lol

all i can say is wow Uriah let me run his plus-4 yesterday ultra smooooth power and more then enough power to over shoot every jump.came off the track running 170deg so much more if you wanted i was not in any want trust me.im on the list to get one of these super motors.Uriah is an awesome person also.

Uriah is an awesome person, always willing to help someone out even if they did not buy one of his engines. It just goes to show the kind of service he provides and the kind of person he his.

Ran at our local track (LA Thunder and Hobbies) today getting ready for the Battle at the Beach in Ft. Walton Beach, FL next weekend. I ran my Murnan Modified JX 21 with my brand new Z-Car, and I TQ'ed and won! No problems with the motor or the car.

URIAH, YOU THE MAN and I will seayya next weekend!!!!!

Just wondering if the either the modified Vspec or JX come with ceramic bearings? Thanks

I am pretty sure they do not, however, I am sure you could talk to Uriah and get a set put in for you.

Novarossi 21+4 update. This motor is STUPID! I have a little over 2 gallons through mine and its a monster. I am running the 5.5restrictor and the trinity big boy pipe and this combo makes crazy yet driveable power and amazing runtime. Definitely worth taking a look at.

hey not to sound like an idiot, but what is a modified motor?

No worries my friend. The only dumb questions are the ones not asked.

Basically, Murnan will take the motor and ask what additional characteristics you would like added to the motor. For instance on the 21+4 I wanted more power and if possible more fuel mileage. So from that point on, Murnan cut, ported, or whatever he does to motors to give me more power than stock and additional runtime. So more or less, just little additions to make the motor perform better.
