I can get dimensions of my old con-rod.. if somebody has measurements of a newer rod so i can compare.. that would help me out a ton.
No, some have smaller crank pins. If you know what the engine you have is and post it here I am sure that some of these guys will know what rod to use.

this motor is probably 15-20 years old. The case says nova on one side, and 2000 on the other side. One of the mounting flanges has the word COMPET stamped into it. Here it is before i started rebuilding it. I will snap some better pics and get some dimensions of the internals.

I have the engine sitting on my bench at work, so hopefully i can remind mysefl to do this



It is the dirty old engine on the right

The 2630 was made for the 2008.

Has anyone with a .12 353-09 used the Novarossi Rubber Front bearing (#17009) instead of the standard metal shielded front bearing (#17010)

Opinions?

works fine Mike. probably the rubber is the easier long term option. I think all the 353 09's come with the rubber sealed bearing now. The first batch had a dodgy set of bearings it seems

No, mine is a late 2009 version (fresh from the factory) and it comes with the metal shield front bearing.

To be honest, I never knew Novarossi had an optional rubber version for the 353-09, and it is exactly the same price as the metal shielded standard front bearing....

Default Flash .21 Conrod - Longevity

Hi everyone,

I believe engine break-in is quite severe on conrods - so could anyone advise me as to how much running they would recommend a conrod (R7, from a .21 Flash Special Tuned) to do after having being "pre-run" before sale, and then the run-in completed on the track?

Cheers,

Kronos.

Default Flash .21 - Gudgeon-pin clips

Could anyone tell me if it is possible to use the gudgeon-pin
clips with part number 05000 in the Flash .21 Special engines?

- Although the exploded view for the Flash shows that a gudgeon pin clip
with part number 05001 is required.

Thanks,

Kronos.

Kronos, you are correct that the rod is stressed alot on break-in and that is why I bought two Go-Tech rods that are the same size as my 35+21 and Kangaroo motors and use them exclusively for new engine break-ins only. I also use off-road 14mm or 14.5mm cranks in the new engines as well so the new crank-pin on the new crank isn't worn prematurely. After the engine is broken in and no ill pinch, I re-install the unused new rod and new crank back in the motor and off we go. This was the best piece of mind for me since I didn't want to damage my new stuff on the most critical time of a brand new engine.
