No Ben the Darn snow came in this weekend and it's so depressing! I've been cleaning the shop and setting up the ZDZ 40 to break in.
But I am going to try something like I did with the 63 is put the OS91 Pipe and YS 91 Muffler without the baffle on the YS 53 to see what the RPM changes are. So I can tell Chad Northeast.
