how much better is the R carb from stock? Worth the money spent over any other performance item?

IMO you don't need a big carb till you get big motor... not saying it wouldn't help but that money could go towards some porting or somethin of that nature ;) ...

I would have to agree mostly on that ^^^ ;) Im sure ther eis some benifeits but enhancing the motor with a few mods will wake it up as well. I am very pleased with it

The throttle position sensor just gives feedback to the ignition system on a 450r to optimize the timing. It won't change anything if you leave it unplugged; the carb will work the same.
