35 years ago, the only thing on my mind was how to make my bike(s) faster, and I had a couple that were extremely fast (by the standards of the day). Compared to today, it was much more difficult back then to get any kind of major horsepower/torque gains, it was always a combination of several mods, rather than just a couple. This was before ECU's, limiters of any type, heck, fuel injection was not common until, I think, early 80s.
I remember when Kawasaki introduced their first bike with EFI, it was the KZ1000LTD, don't remember the year. The amazing thing about that bike, (to us), was that one could simply add a 4 into 1 exhaust and gain about a half a second in the quarter mile, no rejetting, no fuss, no muss, the EFI "computer" took care of all of that. We spent thousands of dollars converting stock 12 second bikes to screamin' 11 second bikes,

, and I loved every moment of it. I had a Kawasaki H-2 750, which was king of the hill until the Z-1, they were both mid-12 second bikes in the quarter mile. I sent my cylinders and cylinder heads to a company called Denco to be bored, ported, and polished, installed giant mikuni carburetors, expansion chambers, slicks, wheelie bars, (for the track), heavier clutch and springs, and a few more things I have forgotten about. I probably spent a couple of thousand easy, in those days that was a bundle, (the H-2 retailed for $1200 brand new). My radically tricked out bike was now about a second and a half quicker, (best run was 11.18 @ 121 mph).
Now, like Ferret, I have no intention of modding my CB1100, because I like it the way it is. (This flashing thing does have my attention though,

), even if I were to flash it, I would not change anything else. I fully understand guys modding their bikes, I've been there, and I think it's really cool what a lot of them are doing, it is always interesting to see the results. Go for it guys, let us know how it works out.
Cheers
