do you gain top or bottom end with spacers. was wonderin cause i just installed a new bills pipe with carbon pro reeds and it seems like i got alot more upper mid and high now. im runnin 13/39 gears with 18 tires and would like a little more low end.should i switch to a 40 in rear. was running a 42 and seemed way to tall geared for mx ridin. thanks for your help guys....

 

spacers are supposed to give u low to mid power.
