Oops didn't read the last few posts, man your quick with the credit card! Looks like you got all the tools you need now! The cam bolts are not on that tight, I think your footboard is torqued tighter, make sure your using blue lockright in everything and get your self a torque wrench, if you don't have one check out the pawn shops you can usually find a nice snap on or Mac for 80 bucks

I installed a new set of lifters in my bike when I swapped cams last winter, but that was only because a set fell into my lap for next to nothing. The set I pulled out looks like new with 30K miles on them, so I'll just keep them for future use. The roller lifters don't develop wear patterns like flat tapped lifters, so they don't need to be replaced when you do a cam swap.

Got the cams swapped and the bike back up on the dyno and gave it a thorough tune. Like the TW-555's, the valvetrain with the SE255's is nice and quiet and the exhaust note is very similar. The SE255's actually performed pretty well overall and ended up about where I expected. While these charts show the differences pretty clearly, I was figuring the SE cams would make a bit better power in the lower RPM's as by 2600 RPM's the Wood's cams have the advantage and make over 10 more peak HP, but on the other hand I also though the SE cams would fall earlier than they did, overall the SE cams did OK in my book. Both cams work very well, it all depends where you want your power and how much of it you are looking for. There is no doubt Bobby Wood did his homework with the TW-555.
This was an interesting comparison, and I'm sure more than a few folks were surprised by the results.

Rick, you need both inch/lbs and ft/lbs torque wrenches. If you were a little closer, I'd have been more than happy to give you a hand. This is one job that anyone with a little mechanical aptitude can easily handle. I'm a cheap S.O.B. at heart, and anytime I can save a couple of bucks, or help a friend do the same, I'm all over it. Plus, these motors are very pleasant to work on, most everything is easily accessible. What could be more enjoyable that that, unless it's actually riding?
