All about reed spacers -

That's called stuffing the crank case. Some enignes have wasted space inside the crank case. If the fuel/air mix doesn't have to go through or fill these wasted spaces the mixture gets into the combustion camber faster. The kx500 has very little wasted space but some one could stuff the lower end of the crank case. I agree the spacer increase the length of the intake track. If you could shortin the intake track you could make a more higher reving engine. Same goes for the pipes. Longer header pipe can make better power over a wider power band. Shorter pipes will make a short peak power across a narrow power band.

I just installed my Moose torque spacer, can't wait to try it out. I was very concerned as initially when installing the kit, you are effectively moving the carb and the carb to airbox boot closer to the shock spring. I thought for sure the boot was going to be rubbing up against the spring. After everything was tightened down, and properly put in position, there ended up being a small amount of clearence between the boot and the shock, so all seems ok.

Yeppers! She be tight! But she make the grunt power!! :lol: :lol:

A GEORGEOUS day to ride today! Had a lenghtly opportunity to shake down the Moose torque spacer. Overall I am very happy. The torque spacer makes for a far smoother torque hit from off idle right into the midrange. All's I had to do to avoid a huge 20ft. puddle was stand, lean back a bit and abruptly roll the throttle, and instant power wheelie! The biggest advantage I felt with the spacer was the consistancy with the torque. I definately also agree this is a sweet mod to compliment the 5's beastly power. I still need to jet down a bit, but I am running straight CAM II race fuel, and the 5 really likes straight race fuel as far as crisp throttle response. I have an idle dialed into my bike, as I find it much easier to ride trails.

How do you guys think this would work in conjunction with EG mo-better porting I have?
