What are the main diffrence between the Plus 12-3 and Plus 12-3 SC.

I only recognized that the SC have ceramic ball bearings and a 11.9mm crankshaft.

I know C = Rear Ceramic Bearings, T = Turbo Crankshaft, but I don't know what S means ?

I soak and gentle wash my filter with highly concentrated detergents, about three times cleaning process. After complete drying, I right away give filter oil and keep them in clean containers, ready for use anytime I want. Mostly they could last about a year.

The main difference is the .4,, increase in crankshaft diameter. Nova also added an O ring to the head button. The Exhaust ports are constantly changing from Novarossi. This is also different depending on which +12-3CT you got. On the brand new batch of +12-3SCT's the transfer ports are a slightly different shape for the better.

interesting to see that they went to 11.9mm rather then 12mm with the crank, i guess it makes buying replacement bearings hard without getting genuine ones.

Default Is this ROAR/IFMAR legal

Does the 353 have too many holes in the cylinder to be legal?

As far as I know, they consider holes below the top of the piston (i.e. that are not opened to the combustion chmaber during the cycle , as cooling holes. Don't nail me on it though.

Actually, better don't nail me at all

Hi guys:

The new 2630 pipe is good for the old NSR12s5 engine?

i know orion had protests at the worlds from the other manufacturers regarding the slits they had in their liners on the wasp rev, i'm sure it got over ruled because they were not extra holes, but a hole with a slit so not technically extra holes in the liner...

the extra holes in the nova while technically not part of the combustion process are extra holes in the liner because they are holes, this could be a very grey area on legality indeed.

I have a JP Mod Plus 12 - 3 and have been told that the "C" designates 11 ceramic bearings. Without the "C" there are 9 ceramic bearings.

Can anyone confirm or deny this?

Thanks

Hi All, I was wondering if you can put a 7 port Plus-7 p/s into a 5 port Plus-5? Like the older 7 ports in the p5. Thanks.

THIS IS THE NEW EFRA RULE CONCERNING .12 ENGINES
5.1 Appendix 7
The engine may have a total capacity of not more than 2.11 cc.
They shall be air-cooled, with front rotary valve, two-stroke induction.
The engines may have e maximum of four (4) ports in the liner, including the exhaust port, seen with the piston at lowest position.
No form of forced induction is allowed.
No form of variable port timing.
Only glow plug ignition is allowed.
One additional gap in the bottom (skirt) of the piston is allowed.
Additional slits or holes in the liner for cooling purposes are allowed as long as they do not reach the top of the piston at lowest position.
Standard and conical glow plugs allowed.
Where ever we say hole in this rule we mean a hole that is surrounded completely by material.

and i also know that because of the protest aver the Orion engines at the Worlds, IFMAR also ruled that slits or holes in the liner, below the piston at BDC are legal

Thanks AFM. I guess Stefan was correct. I like these rules.
