I'm a little bit confuse, what's the difference between
RB Touring 10 RC and RB Concept Touring 10 RC?
are they the same? If not, which is better
for racing in short or long tracks?

the T10rc has more power up top them the T10

They are the same, some times they call it RB Concept Touring 10 RC and some times they call it RB Touring 10 RC.

They only produce one T10RC

The T10 is a different engine, it is less power full then the T10RC

If you want to know something else just post I will help where I can

The technical details are all most the same:

This is the full RB T10RC Spec

RB .12 top range engine, the Touring 10 RC benefits from a lot of new features. Its exhaust port is 0.5mm higher for more top end. The crankshaft comes with the silicon paste orientated at 20�. The inside diameter with conical shape is bigger than it was on the T9 RC. The new venturi allows a better air flow. The most powerful .12 engine ever according to our team drivers during the test session. - 3 ports EFRA/IFMAR homologated - Light machined piston rounded - Hand tuned crankshaft with conical shape - Turbo plug - Turbo combustion chamber with o-ring avoiding vibrations and preventing dirt - 11.5mm main bearing with extra large balls. - Aluminum 6.5mm carburetor with new 5.50mm venturi with very special shape - L2G cooling head with extra fins for a better engine cooling (special shape for INS box) - Aluminum orange anodized wrist pin - Orange dust protection caps.

that is right the t10 is a great motor for short tracks runs cooler them the t10rc

but if your going to run long and short the t10rc is the way to go crazy top end but down low you will have to play with your grearing to get it to pick up and go like the rossis do

but to tell you the truth you cant really see it over a rossis

Does anybody know the specs of the crank between the T10 and the T10RC?
I have the engine apart, so I may as well make my T10 into a T10+
And also, is the exhaust port really 0.5mm higher in the T10RC compared to the T10?

What head clearance should I be shooting for on the T10RC? I'll be doing the solder method.. It comes stock with a .3 shim. Is this okay for 20%? My 9RC needed another .1 to stop detenation. tia.
