[QUOTE="JakeBoucher, post: 194276, member: 1844"] Oops didn't mean to make 2 posts. I believe I found the real deal! It's not a power valve, it's a Variable Exhaust Resonance Chamber. Like Hondas ATAC setup. Power valve was introduced in 87 on the RM250 called AETC "Advanced Exhaust Timing Control" AETC is commonly seen on the flywheel/magneto covers I think. I'll find out the first year the Variable Exhaust Resonance Chamber was introduced [/QUOTE]
