Is the drivetrain free rolling? Brakes or bearing issue maybe not the motor at all.

Well, it's sounds like it's starving for something.....either AIR + FUEL + SPARK.....have you checked ALL of these components and their respective functions?....take the air cleaner right off....take the gas cap off.....

What is different from when it ran fine to now? Did you change any parts or settings? Anything strange happen like run through a puddle or some extreme heat/cold?

The worst thing to troubleshoot is a worn crankshaft seal. Try wiggling the flywheel and clutch side to side. If they is ANY play at all then I'd bet my first born that you got a airleak at the crank seals. Those are pretty dangerous since once they go you get all that clutch dust sucked up into the engine.

I Will Try That When Iget Home .ill Let U Now This Weekend ,i,ve Git 4day Off To Figer It Out.

its the brake, mine did the same thing, once it cools down it will not drag, when you run it it gets hot and drags, i see this on 3 out of 4 redcats i set up, simple fix, spray wd-40 on it , it will break in,
