Will this bearing work as a replacement for a Mito4 or is the Nova bearing the only option?

Nope, no direct fit due the smaller inner ring. You are stuck with the most expensive bearing there is.....

I have modified a crankcase once to fit a normal bearing:

Well that sucks,lol

Does the Hudy tool work to remove this bearing?

Yes, tko has the bearing, same as keep off bearing

The mito have a 14.5mm crank like the keep off 7 and virtus. Noone else makes that bearing cheapest I have found for a replacement ceramic for it is about 70us

you sure?

thats the replacement for 16002

I'm pretty sure that the bearing that is posted in the link is the one you're looking for...

No that's the wrong bearing. For MITO4 you need a bearing with following dimensions:
Ø14,5x26x5,7x4,7mm - 11 balls

Will be hard to find a replacement.
Original NOVA numbers are:
16009 for steel bearing
16006 for ceramic bearing

Sorry, same as keep off 7,mito = virtus + keepoff technology

warning to anyone runing novarossi engines seems there are some bad conrods
out there
after runing novarossi and novarossi based engines for nearly 20 years i had
my first new con rod fail and novarossi decided they do not warrantry replacment rods or the damage they cause to your engine.

Any further link to this happening on others engines, or forums? What motor, how many gallons? Been running Nova based motors in On-road since around the time Serpent had the Nova/Mega 21's and TX15 and knock on wood, no conrod failures here. Offroad I have only run the P5XLT and a P3XS, Strange.

Please post up the engine model and batch and year from the case if possible.

His story in the Nova onroad topic:

http://www.rctech.net/forum/14774327-post5191.html

Kinda funny, after 3 months of used. Within that period, anything can happened

If I am right he just placed a new rod. Not sure which one he have placed, this motor comes with a lighter new designed R4 rod which I do find it tricky. When a replace is needed I do replace them with the rock solid R7

the engine was a mito 35 on road engine had just about been fully broken in
and was in exellent condition when the r7 rod was replaced to keep the engine
reliable. the new r7 rod bush failed on the 5th tank of fuel.

not 3 months of use, novarossi have had my returned engine for 3 months
before looking at it.

the replacement r7 rod was purchased from my countrys distributor
in the first shipment novarossi sent out after there summer break

On the R7 rod there is also a number engraved, I believe the latest is around 15 or 16.

can not answer that novarossi still have my engine.

where did the rod break ? how old was it ?

Sorry misunderstood ur meaning, dont know about the new rod though

I just purchased the elite 5 and paloma limited edition. Which one should I use buggy and truggy? I run on an medium sized indoor high bite track. Thanks! Michael

The last Nova rod is the R7 (14) ...

I would run elite 5 in buggy and Paloma in truggy. I know the paloma with the right pipe and header is pretty strong. I havn't run it myself, but know some that have.

I think the paloma limited is more a buggy engine, but the blue head extra long stroke will be an excellent in truggy or buggu

the crank end bush failed and brook up the rod was new and shiped from novarossi when they reopened after there summer break.

the newest batch i got not long ago are new redesigned more like the old R4 rods of 2005 or so ... R7/16 it seems as though the aluminum is harder in these newer rods ... not sure yet ... havent had one failures from any customers with em ... soo i am thinking they may be good

the rod is literally the weak link in these little 2 strokers ..... all manufacturers are susceptible ..... too heavy they dont run right ... too light and they are weak and both effect the reciprocating mass ..... whatcha gonna do

warrantying any failure in these engines is a slimy can of worms

once they are fired up the warranty is basically null and void ... the one that there wasnt really in the first place :lol:.... but .... especially since you personally replaced the rod there would literally be no warranty expressed or implied from ANY manufacturer whatsoever ... that unfortunately is the nature of this beast

hope this helps

Which is the best engine for a truggy Mito-7, Paloma, Elite-8, or Legand-7. Any advice is welcome.

mito 7 .....feels better for a truggy ..with 9901 and manifold is up to you after test ...i would try 41005 :)or 41021.....adam drake has a video here i think will be hellpfull for you ...https://youtu.be/Eg2AnKWTPqM

Virtus .21/S
 

Hy. Sorry for bad english.. Is there anybody driving a Virtus 21/S offroad? What is your run time with Nova 9901 in a medium dusty track? Which venturi? Novarossi provides 5.4 to 8 mm venturi....
Thanks

I've run the virtus in the past. Usually a 7mm venturi. Runtime was never the best with the virtus I used to make about 8 minutes with it.

understand this totaly but have never heard of a new rod that is not going
through the stress of breaking failing. so called anwser rc, they said send it in
saying worst cass i would have my engine back in a week so i could fix it up
and still finish the summer racing. novarossi looked at photos sent to them
and desided they needed to look at the engine,they then took 3 months
to say thay do not warranty replacment rods.

Hi guys I used to run the plus 21 4 in 2009 with my Losi 2.0 buggy and it screamed. I'm getting back into it again and buying the Losi 4.0 and I'm looking at the Keep Off 21-4 and not sure which pipe to get either the 9901 or 9886 with the 41021 manifold. I want lots of bottom end for clearing jumps but I want top end for long straight aways.
A friend keeps telling me to get the SH PT-2016 xbg, but I know nothing about the SH motors and I remember how great that Novarossi engine ran and I'm reluctant to buy something I don't know anything about even though it's cheaper.

Thanks

A 41021 will give you the mildest power , a 41033 will do better as would a 41001

Maximo, how would the werks 2058 compare to the mentioned nova combos? I've got the 2058 on my keep off 21-4 and really like it!

And which pipe for the Losi 4.0 buggy. 9901 or 9886?

Also is a 3 needle carb harder to tune than a 2 needle carb.

And what's the difference between steel and ceramic bearings? Which is better for longevity?

Guys got a question on pipes? I run a mito 4 and was wondering what is the difference between and ultimate pipe and the novarossi based pipes? Is the ultimate 2123 a mimic of a nova pipe? Has anybody tried an ultimate pipe on a mito 4?
