Quick search showed $115-$180. I could use one for my YSR but I'd want pics verifying it's not a Chinese knock-off (manifold side, near the choke, some numbers like 001.017 w/ maybe a couple letters). Any velocity stack or filter, spare jets?
Could be a 24 I suppose. I'll have to go and measure it. I can send all the pix anyone could want to ensure it is not a knockoff. Just PM me your email. I do not have any jetting other than what's in it (I'll look around to see if I can find any more), but it can also come with a 1/4 turn throttle and cable for a YSR application plus the Yamaha intake boot that makes it fit a YSR. I'm letting go of all my YSR stuff too if anyone has any needs.
