My thoughts exactly. Did you deck the heads at all to bump compression? I read your thread but can't remember. I believe you can take a few thou off without hurting to get a few HP. That with the modded pipes and Murray's carbs, you need to upgrade your brakes for sure LOL
No, we decided not to bump the compression. It's already something like 10.1:1. Didn't want to have to go to premium fuel. The guy that owns the bike is a daily rider. He rides it to work every day, (when the roads are clear of snow and ice, of course.) If we had to bump it up to premium fuel, his annual cost of ownership would go up quite a bit due to how much he rides.
Yes, the front brakes were updated. Tony, (the owner,) did the research. He got a caliper off of eBay that was dual piston. Required a different mounting bracket, too. I didn't do the research, so I don't know what combination of caliper and bracket it was. We rebuilt the caliper and the master cylinder. Bead blasted them while we had them apart, and powdercoated them. Also did braided brake lines.
Forks were updated with Progressive springs. Tried to install emulator valves, but the ones that Tony got didn't fit. Still, with the right preload, and 15 wt fork oil, the forks worked quite well.
The bike got a thousand other things, too. We pulled the triple trees, installed All Balls tapered roller bearing upgrade, and installed a grease zerk fitting in the stem. Powdercoated the triple trees, too.
The exhaust "H" pipe was removed, and we made them into true duals using Murray's pipe mod and glass pack megaphone "mufflers." I would like to try the Mac 2-into-1 pipe on one of these bikes sometime.
