There is a mamba .25

Iam sorry no there's not a mamba 25 I was thinkin blackmagic 21

That's ok ,any one have specs on cobra .25 sleeve outer diameter . I think they are the same . Have a monster .25 got off of juskirc year or so ago and want to rebuild

I can tell u that the bore on the 25 sleeve is 17 mm

I have a cobra X2 In a XB808. Love the engine. Temps constantly run around 280 degrees. This seems to be where it wants to run with out bogging rich or lean. Thoughts????

ALL THE AXE ENGINES I RUN TEMP AROUND THE SAME THEY SEAM TO RUN VERY WELL 270 -290 F

HOUR LONG MAINS I HAVE CAME IN AT 300-305 F AND THE ENGINE IS STILL READY TO GO FOR MORE

BLACK MAGIC .21 THE BEST ENGINE I HAVE RUN.

Thats the temp mine wants to run at. It's a beast at 290

Any recommendations for fuel. What oil content to help with temps but not burn it up.

Cold Fusion 30% Majic is the BEST fuel you can Buy. I have been running it with my Axe Rossi motors for 3 years now and Just Love the fuel.

We have like 10 guys around me running the fuel now a lot of the guys came over from Bryon's and pay the same price for Cold Fusion so that tell you its a better fuel when some one pays the same price.

Yea coldfusion 30% is good when I started with coldfusion I noticed lower temps and more consistency in the tuning with the engine

I don't know what this is but thought someone might want to look at it.

Axe Rossi motors have fallen out of favour in Australia due to them constantly flogging the bottom bush out of the rods. I have personnely had 2 fail and have seen at least 10 others. It has got to the stage in Australia now that you can pick up a cobra evo for $229 at Ultrahobbies as no one will buy them. Unfortunately the new updated rods seem to be failing just as much as the old rods. They fail in all motors but if you have a .25 cobra it is a given that you want make the 7 litre mark before it fails. I love the motors and still run them but not with the axe rod. I use the nova rod or a go tech rod in them and they don't have the issue.

What we have noticed is that the machining of the tapper on the intake side of the lower bush to allow it to slide over the crank pin is the issue. If you look at the tapper on the rod you will notice that the machining of the tapper is never poor and you can actually see 4 machine marks on the face of the tapper. These have an associated step in the material and over time these lines/ridge develope into fatigue cracks and the bush brakes appart.
What i have tried in an old .25 cobra is to take a tappered grinding bit and manually grind down this poor machining to remove the ridges and hopefully solve the problem.

Don't get me wrong i love the engines and will continue to run them but not with the axe rods in them. If signs of the probems are flame outs and poor idle if you are haveing these problems pop the back cover of and check the bush.

Good luck.
