Yes all new motors have new rod I never had a motor give me 6 gal before it needs a rod these motors are also turnin some serious rpms

... first of all, Iàm not in for a fight about these things ! Our buggy team`s very cloose to the distributor here. My only interest is in passing on good advise about the problem that these engines do have.

We have had 8 team-engines (Cobra X2 und Mamba X1) breaking down / blowing up with conrod problems, also some using the newer conrod.

We are very into break-in, in the car or in bench. We pre-heat, use higher content of oil, heatcycle and do not racetune before aprox. 1,5 -2 gallons. Conrods should be changed after break-in, because they all show wear. If you go on without doing so, we have bad experience passing 8 -10 liters.

Still after changing the rod, they will not run more than 2 - 3 gallons before they start "eating" the brushing.
The GO conrod seems to take the beating better !

When the Axe engines runs, they are great engines, - but still not quite up to the fuel economy of high-end race engines.

- all this, not to harm, but just inform about our experiences with the Axe.
kind regards JessK

... A Mains have the updated conrod since :

- all our engines had new rods.

We have had good luck out of the Rods me and my Friends but some have not to each there on.

If you are not getting 6 gallons out of your rod i am SORRY i have been and i have one Motor that got 9 gallons on 1 Rod so i must be doing something Right that my be way i am a Sponsored Drive for Axe Rossi.

not to sway sides to this conrod debate, but i had mine changed after run in + 2 race meets... 6L through the engine.

my LHS recommended it due to these rods failing and destroying the engine. they recommended the novarosi engine and claimed that i'd be hard pressed destroying this engine now. i paid $60% off RRP for engine/pipe combo so an extra $70 didn't worry me.

onto another note... last race meeting i had my engine properly race tuned. i can still go a little leaner on the top end, but this engine is creating a serious amount of power.

In my first race meet after run in. i canme 2nd in the B main final running an engine that was way too rich on the bottom end and still managed reasonable lap times on our track.

awesome engine. good run times. was running 8.5min before race tune, not sure what i'm getting now.

So.. Why doesn't someone make a rod out of titanium with replacement

bushings?? Should last a lot longer I would think..

Axe Motor Rossi Takes another Win in the Arkansas Dirt Oval Series Round 4. I Won 2 out of the 3 Heats and Won the A Maine. I was running the Serpe .21 Motor Temps ran 235-240 all night and the motor had Tons of power i could Pull any Car any time i needed to. This is the Best Dirt Oval Motor Money can Buy.

THANKS Axe Rossi.

congrats. my next race meeting is 12th Sept. we only race once a month here.

I have a new connecting rod i have designed and is currently going threw testing so far 1 gallon+ on it no signs of wear what so ever


wonder what would happen if brass bushing were eliminated from connecting rods????? -BOLEY RODS- comming soon

Let me know how the New Rod works out i have been thinking about a Rod with some other Kind of Bushing to. Would Love to see some pic of the Rod you made and some more Info on it. I think the Brass Bushing is Old Tech and we need a Rod with something Stronger with as much RPM and HP as these Motors are making Now Days.

As soon as the latest one completes testing about 3-5 more gallons
I will have one to send out to ??? a sponsered driver ??? and would like a reports on preformance. I am currently looking into a patent i don’t want the engine mfg's using my design without paying to use it

My design will give more overall more performance and run time on there engine then any current one on the market

Every current engine even broken in properly start loosing performance after break-in "really from the first rotation the bushing starts developing play and not letting the piston reach tdc that it was designed for. we are talking hair's here but this new rod will keep the original full stroke of the engine and not delvelop slop

first try: i took a old axe rossi engine that had 8 to 10 gallons "soft chasing tune ready for a change" I installed this rod and it was like a differnt engine more pop/pinch and it's keeping tune
currently on 3 gallon after install and it is running great



i will post more at a later date

FYI "i delvoped this for AXE ROSSI motor in mind i love there engines and would like to help them regain their market share in the industrie

I THINK THEY NEED SOME THINGS TO MAKE THEM STAND OUT VS ALL THE OTHERS OUT THERE

I FEEL AS A SALES AND MARKETING MANAGER THEY SHOULD REVERT BACK TO THERE OLD COOLING HEAD DESIGN FOR THE LOOK BUT MAKE SOME UPDATES TO THE HIGHT MABIE A RECESSS SO THE HEAD SITS LOWER ON THE BLOCK

I sent you a PM i hope we can Work together to get Axe Rossi back to the Top.

I would like to add that 6 to 7 gal on a rod. Or rod bushing may or maynot be common this is what. I have gotten but its always a good idea to change rod every 3 gal to be safe on ANY ENGINE and I agree that changing rod after breakin is good. Also havin a rod made with a better material or a bushing with better material would be nice.

I have an axe rossi speed motor .21 just threw break-in.
Good / Bad
Price if I was to sell?
