Reed function 101...........

[LivingSlow]

I agree with LS....reeds can last a long time. I have 214 hrs on the original reeds on my 00 GPR. Rebuilt it a few weeks ago just due to hours. Reeds looked great. Reused them. Engine runs great now.

Hey ButterBean did you put any sealant between cages and case, reed plate and cage? It didn't look like there was anything sealing the two on my 800 I'm just wondering.

Thanks LS and Butterbean! I will inspect and if needed replace. I will document my rebuild in this thread:

Interesting to me and somewhat related, even though it is the enemies technology. Rotax Rotary valves remove reed pedals and is in fact completely different than reed systems.

There is a geared-to-the-crankshaft semi-circle disc that blocks the intake ports to the crankcase. You can imagine as it spins, it reveals the intake port for the intake stroke, then the disc blocks the port during the rest of the cycle.
