All great information. Exactly what I needed, and what I hoped to learn and confirm.
One of the best features of that 790 motor is the cam. I'm not expert enough to say, and can not remember, whether or not that cam was exclusive to the Speedmaster, or common in both models, but without a doubt, it did make it very fun to ride. I don't know if a similar cam profile is available for the 865 motor, and I wouldn't have ever considered changing cams in the 2009, as it was. It seemed to be adequate as it was. Whether or not that 865 motor with carbs is noticeably different than the 865 with EFI, time will tell. I'm sure I'll get used to it, either way.
I'm still looking at the 865 motor as a "loaner". Once I get the 790 out, we will sort out what's wrong with it, and ultimately, I'd like to put it back in where it belongs.
I could get another bike, but the wife and I wouldn't likely agree on what that might be. A big, honkin' Barca-lounger is not on my horizon.
I'm excited to see what Triumph introduces this Fall in the way of new Bonneville-engined cruisers, though, and certainly won't buy anything before they come out next year, anyway. If I ever do buy anything new again. The 2004 might just be the one and only one I'll ever need.
