Since this woke up...... 1992 FLHTCU, 100, pretty much the limit. I have no idea what cam is in it now but I did put fresh stock compression pistons when I went through it a year ago. And I did change the back pulley to a 65 tooth.
The fastest bike I ever owned was a Suzuki DL-1000. That thing just had gobs and gobs of go in it. Easy, relaxed power, even at crazy speeds. I ran an hour straight at an indicated 120+ (which is probably 10% or so faster than actual) in Wyoming on that thing once. It never felt strained.
Back in the day, I had the chance on occasion to ride some truly fast bikes. Liter class sportbikes are in a class of their own. Just insane, and they have the chassis and riding position and suspension to deal with ridiculous speeds. When you're on a Hayabusa and it is still pulling ferociously through 150MPH, you know you're in a different world. Riding those things at anything like legal speed seems like a total waste of time.
I haven't found the top end on my recently rebuilt ElectraGlide yet. I've only got 300 miles on the motor, and want to give it more miles before really getting after it. I can tell, though, that she has a lot more left in her at 80 than she did before. The only thing I know about my Sportster is that she will go way faster than I want to. With the tall bars and upright position and lack of suspension, anything over 80 is too much of a thrill ride for me.
When I first got into Evos a few years ago, one of the things I liked most about them is the real-world performance envelope. I like the saying "Its more fun to ride a slow bike fast than a fast bike slow". That's me.

I still got my '91 fxlr I bought new. I was 33 then. I DISTINCTLY remember having seen 120 on the speedo 4 or 5 times. Scarey as hell to think about it. Stock! My first HD was an 883 in 86. First year. Not a big performer, lol. That first year of the fxr, I went with 3 other dudes to a huge party here in Ohio. Called Wetzels. Seen **** I never seen, lol, that's another thread. One of those guys had a late 80s fxr with mikuni, cam, pipes. He couldn't hang with me when we split for home late sat nite. When we stopped at a stop sign he asked "wtf you done to that thing? I can't hang with ya!?". My bike was completely stock with slippers. Felt great for a newbie. Lol.

So, Just as the title states.. Top Speed.. What is the round about top speed of this engine. I get up around 80 and the whole world begins to vibrate. It seems that it wants to pull past 80mph but I don't want to do any damage if its not meant to handle it.
I have basic mods if it makes a diff. V&H pipes, KN air-filter, stock carb. 96'fxstc
*disclaimer* I dont normally travel at these speeds, but pulling out on to the hwy the other other day I had to get on her to beat the traffic.

If the stock carb isn't jetted, then about 110 is all you're gonna get. A jetted one should see a buck twenty. Give or take...
You gotta tach on that bike of yours?

I doubt if Buttercup my Buell Firebolt with 100HP will exceed 130mph and that is as skinny as a lath, compared with any big twin. What kills horse power and speed is drag, mostly wind resistance, so a static rolling road is no judge of what a bike and rider can actually achieve out in the real world.
