throttle assembly

[usp4u]

curious as to what thumb throttle assy everyone is using. my walsh yz450 has what appears to be a throttle housing from 250R. it is stiff, especially 4-5 laps into a moto. is there something with a better leverage ratio? i'm running a stock FCR with a single cable. thanks.

I run 400ex w/ TRX450 cable to FCR carb...its like butter.

i've heard to use 400ex before, guess i'm gonna have to pick one up.
