Great low end snap from it

Got this for my 1987 LT250R to make the carb further back and creating more power. Great low end snap from it. Bolts and such are exact.
Great

Great
Reed spacer adds torque!!
By Rsizzle6 on
Recently added one to my son's YZ80 and it now has low end grunt like never before. I let him test ride around the yard and all he could say was "holy cow, what did you do to my bike?" He woke the next morning before sunrise with excitement to ride.
