I will make that call, I know I can still find a Con Rod but even if I could just find a piston will be great, I never pinched a sleeve before so do you know if these would be a good thing to try on a motor with 3 gals gone threw it ?

The C10's I am running now I break in for 2 gallons , then change the rod and race them for three gallons before they need a P/S.

Thanks again Bro, this is some good info mind you that this is my 1st time ever owning and running a RB Motor.

Yes, no problem.
For bearings I would advice you to stick with the RB ones, RB uses 9 balls for the rear bearing and they are far better as the 11 ball version which nova makes.
Basically the Rb 2604 '2009', Nova 2660 or the 2662 from Capricorn.
The 2604 I would describe as an allround pipe, it gives a good amount of mid end power and makes for a nice linear engine. Also easy to tune and easy on the fuel milage.
The 2660 gives the engine more top end power, and uses a bit more fuel.
The 2662 gives the engine heaps of mid and top end power but uses quite a lot of fuel and made it a bit harder to tune, but the most overall power.

You might have better luck finding the C6 set. I got mine from Ashford hobbies.

Hey Bro's
I just got my hands on a used Rody C5 .21 On-Road, it has about 21/2 gals gone threw it. I have place it in my MRX4-R and ran it till it reached 195 degrees but it seems like it dont want to hold at idle or seems the high rev are cutting out. Do anyone knows where or what should the Carb/Needle settings should be at ?
Thanks
p.s this is my first time every running a RB motor.

guys..after a full day race, i disassemble my engine. everything looks fine except the top surface of piston head which had quite a few small spots ( feels sandy ). it also appears on the bottom part of turbo button ( the area around the glow plug.) , has anyone experience this too? so what could be the cause of these and what should i do to prevent this from happening again.
and how do i remove this sandy spots stains, ? thanks

This causes pitting on the piston, head and glow plug. If you see pitting it means you are running too lean, you need to richen the mixture slightly.
Also Bro I would to be in the PI's !! some beautiful woman out there.

Bro I believe your motor is starting to Detonation happens when your mixture is too lean, This is when the air and fuel mixture ignites prematurely. It happens in different places in the chamber all at once, you can normally hear it when it happens and your can will loose some power, but it’s not a major problem unless you don’t pit. If you continue to drive you will damage your engine.

( u see i ran a 45 min final with that mixture, my pitcrew must have not notice it was getting lean) i did not notice power loss during that final. anyway i agree with u . thanks again
