Ahem: Motorcycle Daily test rider says:

"That vibration at higher rpm levels reflects the fact that this particular Guzzi likes to be short-shifted, rather than revved....

Ahem: How can I say this politely? Bullshit!

I have owned an EV for four years; put 25,000 miles on it; it has taken me though most of Florida and a good part of the Southeast, Mid-Atlantic, and Midwest regions. One thing I can say with confidence is that the author of that article has it exactly backwards.

Got it back from the shop today, after tappet adjust, TB sync, and hotter plugs. Runs slightly better, but it's a solid-mount Guzzi. Sweet spot is at 2,300 rpm. Sure wish there were an aftermarket rubber mount retrofit kit. With the engine mounted sideways, the hammering is a way of life with a Guzzi. Wonder if BMW airheads are rubber-mounted.

If the sweet spot is 2300 RPMs there is still something amiss . AND NO , airheads aren't rubber mounted .

Yeah, in contrast, my Kawa 1600 (rubber mount) is so smooth, it's almost boring. I need meds.

Oh , lots of us need meds ... ;D Seriously , there should be a broad sweet spot with any decent 2 valve Guzzi . 2300 RPMs to around 5500 RPMs . At least everyone in my experience has been sweet , and that is a few .

On most big blocks the really sweet spot is around 4200. :beat_horse

Yeah, sweet spot should be from 3k on up. It's smooth until the bike bounces off the limiter, not that I do that.... often.

don't lug a Guzzi.

4k rpm + on the hi way.

MotoGoosy · « **Reply #76 on:** March 01, 2015, 12:40:37 AM »

I'd have to stay in 4th gear to keep it at 4k at 70.

Fifth gear is only useful when exceeding 80 mph.

the way to know for sure is to run it up to 4k. try it, you'll understand why EVERYONE here keeps telling you your running the engine too low.

ITS NOT A HARLEY! Don't ride it like one! If you are running it at 2300 you are riding it like a Harley.. level ground with light throttle 3k minimum highway 4k is fine. Those who say 5th is for 80 and above are looking for spirited throttle response. 4k in 5th will give you 70 mph. Spin the engine.
Did I say DON'T RIDE IT LIKE A HARLEY?
The problem isn't the bike but how it's being ridden.

The problem is a loose nut behind the handlebars.

You've got five gears, but you don't have to use all of them, all of the time!

My V11 Café Sport would really buzz the bars and shake the seat when I first acquired it. Only gel gloves worked. With two other big blocks in the shed, I knew it was not normal. The PO had been using a shop that, IMO, thought they knew how to tune up a Guzzi. Following the advice and procedures found in this forum, I set everything accordingly. Night and day difference. The engine will trickle down to 2000 or so in 3rd on flat ground but very very small throttle opening is the only way to keep the shudder and shake bearable. I wanted to test low rpm fueling after the re-map. OK, done with that.

Rule of thumb-Never ride below 3K, 4K is sweetness and at 5K is all day smooth. Never higher than 3rd around town. 4th is good from 45 or so to 70 then 5th. Strolling along at 80 sees 6th and the 5K mark indicates 90 and a bit. You may need to recalibrate your riding style. Or buy a Buick.

Yeah. I was just beginning to think the same thing.

Rich A · « **Reply #86 on:** March 01, 2015, 09:20:04 AM »

Something still sounds wrong. I'm assuming the shop also changed the plugs when the bike was in for service. Might be worth doing wires and caps, too, if there is any doubt. Checking the operation with Guzzidiag might not be a bad idea.

No one mentioned U-joint--is the vibration the same at a given rpm no matter what mph you are running?

NO!
I have owned a number of Guzzis. I have ridden a few dozen. One of my rides is a 2004 EV with hydraulic lifters. The torque and power curve on the hydraulic lifter EV means that they actually like being ridden at a lower RPM then most Guzzis. That LOWER RPM, is between 3,000 and 4000. Most normal Guzzis that I have owned or ridden prefer 4,000 or slightly above.
If you think the sweet spot is 2,3000 RPM, the bike is broken OR you aren't riding it right.
If your riding style doesn't run the motor closer to 4,000 RPM, sell it.

If he keeps riding at 2300 rpm if the UJ isn't bad it soon will be.

Semper-guzzi · « **Reply #89 on:** March 01, 2015, 10:05:07 AM »

I'm in 4th on the SoCal freeways, if I got past 80, then I'll get into 5th. Shiiiiiite, I've hit an indicated 70 in 2nd gear. But I'm not the best role model.
