Maximum sustained cruising speed?

No one has said it yet that I can see, so I will. I've got a '94 Dyna Convert, the 80 ci evo will run all day at 75-90 BUT, it's a rubber mount. The '93 rigid mount softy may put your hands and feet to sleep, since they start to buzz pretty good at around 75, as I recall. I don't know if the '00 is the balanced motor yet, but if not, it will feel the same way. The evo softail is a completely different ride! Either way, you're not going to hurt the motor riding 80 mph all day, it's certainly capable.

Thanks for all of the replies and suggestions!
I have the most unobtrusive throttle lever I could find on order along with a right side Throttle Rocker. If I like it well enough, I might even order one for the left side before we leave.

Hi guys!
Thanks for the info about Crambuster and Throttle Rocker, didn't know about them.
Also, glad to know that 80-90 mph cruise speed is normal for you too on an EVO, and that it doesn't hurt the motor running this "light". :-)
I ride a 1993 Heritage Nostalgia (EVO 1340) and usually get those sustained speed peaks when riding, but was wondering if it would be healthy for the bike.
A few months back, I got one hydraulic roller tappet blowed and wondered if it could be speed related. The mechanic told me it's a typical issue that sometimes fail on Evos, one of them (don't remember the location on the motor he told me) can fail.
I ended up installing 4 new push rods, 4 new hi performance Crane hydraulic roller tappets, a Torrington inner cam bearing and an Andrews EV-13 cam. Rides great and want it to last trouble-free as much time as possible! :-)
Cheers,

When on a small group ride such as this, the most important item to take is patience. If you get annoyed with other members of the group, it will taint the experience. So just go with the flow and enjoy the ride.
You can run an engine at whatever rpm you want,as fast as you want all day long. More rpms means more oil pressure which means the engine is properly lubricated,so what wear exactly are you concerned about.
Once a motor is warm and the fluids are at operating temp wear is minimal. Every moving part has a thin layer of oil separating them. Hydrodynamic I believe is the term. Anyways as long as you have airflow across the cooling fins and oil pressure running it is a non issue.

When Im cruising at 80mph my rpms are just about at 3,000. I like getting up to 80-85 sometimes (its just fun) but will normally cruise at 70-75, its just quieter and I can still hear the tunes.

Cheers,
PD. No idea of the rpms, I just have speed-O-meter...

I have an 86 Honda 750 v-twin. That bike will rev at 5500 rpms all day long and not so much as burp. It has ohc but it's still a v-twin.
Now I'm not saying run the bike at just under redline but what I am saying is that a properly running engine,once warmed up to operating temp,can run all day long at whatever rpms you want(within reason) as long as the oil pressure is sufficient and it is being adequately cooled.
It's not the rpms that will kill it,it's a failure in either lubrication or cooling.
If you are going to ride around all day at 4000 rpms an oil cooler may be a good idea since the oil and air cool these engines.
I'm sure someone will tell me I'm wrong though.
