mps, have you tuned yet? what kind of numbers did you get? At this time, I'm going to try the HD down load for that configuration and have them rich it out a little. They are going to cc the heads and mill accordingly (keeping the compression at 10:1 or lower).
Carefull on the chosen compression. I am no expert, but most of the info I read here says to stay at about 9.2/1 with the 255 cams, they close VERY early, building a ton of cylinder pressure.

Default Compression

Thanks, I'll have to ask my builder about the compression with the Se 255s. I think I saw on a couple of other posts/forums that 9.6-9.8 (may have been Joe Minton?) was a good number to shoot for.

HD claims you can go to 10:1 (e.g. flat-tops in the Stage II kit) with the 255's, but there are some Stage II owners who've had starter problems with this setup. Some opt for compression releases, and if I was going with the Stage II I'm not sure what route I would go. Adding CR's is really getting too complex for my taste, especially manual CR's that require you to activate every time you start the bike.

As for your question about loudness, there was a noticeable difference on my TC96 with Jackpot mufflers. I went with the smaller baffles but it is still louder than before, though tolerable. That is the only downside to the 255's, IMO, but with all the virtues of this setup I would definitely do it again.

One of these days, they're gonna have electronically operated valves instead of mechanically (=cam) operated ones. Then we'd end all cam choice arguments as they can be programmed to vary indefinitely.

How about an intake that closes near bdc at idle and doesn't close til like 70* to 80* afbdc near redline with no intake/exhaust overlap. Max tq all the way from idle to redline. Heard F1A cars will have those in a few years time as a substitute to the long disallowed boosters.

Then we'll be talking about programming our valves instead of choosing precut cams. Ain't that gonna be fun? Cheers.
