For those of you running the GYT-R muffler insert (and GYT-R clones) would you please post your elevation and jetting? I am looking for a good starting point on jetting my 450 with this thing and I know several other people are as well. There are a few guys here that have really got their bikes dialed in with these inserts and I'd like to hear from you! I am at 2700ft. 155 main, 48 pilot, #5 position on stock needle and 1 1/2 turns out on pas.
