It is gear driven off crank. The blaster has a fixed Exhaust port.the only way to raise it and the power band. Is to remove material an raise port height.this power valve
The blaster has a fixed Exhaust port.port height will not change unless you remove material.the power valve gives you a broader power band. I will take pictures tomorrow and explain .it will be easier to understand

Well then someone decided to remove it on my old YZ. Now wonder that thing scared the ever living crap out of me...I could never predict when the powerband would hit.This is power valve shaftView attachment 34365 just moves up and down according to rpm.View attachment 34366 you can see power valve in the down position it the exhaust port(low rpm)View attachment 34367 upper position(high rpm) wfo how i ride. Notice exhaust port is higher(higher rpm power)
Next time I pass the Boyesen factory, I'll have to take a picture.
That place is small, like mom-n-pop small.
That would be cool to get a picture. Just staying with same type of reed that was in it .replacement petals ate cheaper than going vforce
I can tell you having had a set of VForce Reeds, you're better with the Boyesen. I mainly used the VForce because of the expansion chamber they used on my bike.
Like the vforce run them on the blaster. Didn't feel like spending the 150. On them. It's a spare trail bike boyesen work well
put the two bolts in for csae saver. Should have motor in this weekend .Similar threads
