I would like to give a SPECIAL thanks to Monty for the AWESOME HP he supplied me with this weekend at our NCT race in Burlington, WA. I ran his motors in both buggy and truggy and they were amazing! they were the fastest, and got the most run time of ANY motor I have ever ran I'm sold! Thanks again Monty!

I sure can't

I took my bnib N21R apart yesterday for inspection before break-in now I have my comp-heat and my inverter... as with the previous Nova (+4) i got new, there was a small metal shaving dangling from the plug insert (from the threading it seems)... watchout, guys. Interestingly the crankcase "closure" (sorry, not sure about the name) had some internal scratches, no effect on performance though. The rear bearing was greased like crazy, with grease residues on the crankshaft too. For reference, the crank pin is at 4.97mm, conrod isn't R7 though, but looks the business.

Definitely older gen mill, but I've seen them run on the track and they are not that far away from the $350 mills... And from afar, now they have the new big purple heads, they create the illusion nicely

appreciate the feedback Randy , i enjoyed having you actually enjoy your engines and the 10 min pits

viva la novarossi!!

randy ran
p5xlt "houston tuned" w/ 9853ss/41021 / odonnell 87t - truggy
plus 21-4c "team" w/ 9901ss/41005 / odonnell 87t - buggy

they fixed all that stuff very quickly once they were made aware of what the end user was getting , both Jim and myself sent emails to novarossi

the sport conrod is the E1 , still works pretty well but less copper bushing , good strength though

87T?

Monty just wanted to say keep up the great work, the Houston tuned plus4c put in another great sat for me last weekend.

saweeeet!!

i always try to do my best Matt


if you have an engine from me , please keep me updated on here on how everything is goin for you

happy motorin',
Monty

Hello Montey, I am about to switch bearings in my plus4 and 5k, with ceramics "tko" the front is 7x19x6 instead of the 6.3, I believe I have to use a spacer behind the collet? I think I read this some where in here on you thread. Thanks again sir.

the 17011 front bearing from novarossi is well worth the 25$ trust me

Ok, thank you sir, but I already have the front tko's, should I stll use the Nova's? Ahh heck with it I will order them.

you can install the tko front , leave both the seals on , use a shim behind the collet , replace every gallon or two

nova 17011 install , dont use shim behind collet , i'm going on 8 gallons on one

Is the 7x19x6.3 used on the 5k as well? Thank you again.

the 17011 bearing will work on just about every off road .21 on the market

Thank you very much Mr. montey! What type of oil would you recommend to lube the carb neddle o-rings? I know synthetic, but will grease or oil be better?

Oil , rbmods oil
