    You can also add the map switch, helps when conditions are greasy takes the top end off and puts the power lower in the rev range.

    As for gearing i run 14/49 everywhere From the mountains to dunes and all in between, with propper jetting the right pv setting and adjustable mapping the 300 is the best all rounder.
    Hope this helpes
    Does the red spring and adjusted out work in tight woods?

    Personally i run the red spring everywhere, I ride a lot of tight single track. 1st, 2nd,3rd gear stuff. I find the red spring with pv wound out one turn before flush gives great power and drive out of corners. It really depends onyour riding style. I tend to attack s/t half clutch brake slide to flick the rear then accelerate hard out. Winding the adjuster out brings the power on sooner.

    Ben running the red for a while with the adjuster half way in. Never thought about having it set to full power straight off. Anyway just bought a green one to try this weekend, think I will miss the hit, but it may keep me on my bike more

    Personally can't see that being a great setup for very tight woods, but I will give it a go?

    Thats what I want the 'power on sooner' I know its not a 4st but the power does seem high up! i noticed some of the marketing blurb says the 2011 bike has a new clyinder for more grunt!

    Changed the spring in my bike from the red to the green and to be honest I didn't notice any difference?

    Thats odd, on mine it makes a noticable difference between the three.
