CRF dirtbike chain is what you need not the TRX chain, and yes I would recommend a new heavy duty cam chain.

I would also recommend an 8 plate clutch setup and new stronger basket of your choice..:cool:

A strong motor and weak clutch don't mix to good.

crf cam chain and sprockets or just the chain thanks joe

[sampleez]

i just used the chain. the sprockets are prolly totally different, and for sure geared differently.

Chain only...

haven't checked but i would beileve the CRF and TRX to have the same chain. not positive though

I put a CRF dirtbike cam chain in my 440ex and I also bought a new 400ex cam sprocket just to be safe.

Sparks Racing, GT THunder also offers the 8 plate setup. IT's a LOT better than stock and was money well spent.

Sounds like Im going to get one of those because my 440 will eat up stock cluches if you let it.:)
