2015 V7 stone vibration

[Kev m]

OK, let's assume it's just plain normal.

Let's take the position that IF Dofin wants to keep the bike, he's going to need to deal with the vibration.

How about a play from Harley's old handbook - could you find or fabricate some rubbermounted risers to help isolate the handlebars slightly from the vibration?

Similarly - larger or softer grips and footpegs with more generous rubber?

[Dofin]

Yep, already thought of isolater mounts, have installed vibration tape on grips and will be checking into gloves. 

Hey, 2 liters is two lts.  Sump aint over filled, oil levels has stayed the same over last about 1K miles and no oil in the air box, also I have been at higher RPMs +7K.

I read 2000 cc/122.05 cu oil and oil filter change on page 192 in my Guzzi Use+Maintenance book  Ed. 01_03/2014.  It's a V7 stone 2015.

I think you'll find that the V7s already have rubber mounted handlebar risers.

I assume you're referring to 24 - Rubber Spacer:



Crap, guess I ASSumed they were solid mounted.

Maybe a different material? (I'm probably stretching looking for solutions). Dofin probably has it right, gloves might be part of the answer.

[Dofin]

Nope Mine definitely does not have rubber isolated handle bar mounts.  My GT500 does and that reminds me that I might not want to add them to the V7  the GT handling is VERY rubbery in hard turns, do not want my V7 the same way.

[Dofin]

Well, what ya know!  the handle bars sure feel solid!  Gotta go, work calls.

The bolt that holds the riser to the triple clamp floats in rubber. 

Trust me.  I'm not talking out my arse, and I actually had mine apart a couple weeks ago...

use 2 quarts with a new filter or it will be over full. and that's a bit too full.
did you ad a crash bar or any thing else attached to the engine or frame?
80 on the speedo is 76 at best and that's about when to shift into 5th. keep the bike at 4000 RPM min. 4500 is perfect.
you shouldn't feel any real tingles until about 6000-6500. that's your shift indicator.

Good point.  I put an Agostini's crash bar on my 2014 V7 Special.  For a short time.  I rode it to Tulsa and back, a 250 mile round trip, and removed it ASAP upon returning home.  The darned thing magnified the vibrations to the point where they were almost intolerable at 80mph tollway speeds.

My 1TB V7 Special vibrates.  I don't believe it's because something is "wrong", just that the engines aren't well balanced.

So does mine. Enough that my feet occasionally start to tingle after a couple of hours.

[Vagrant]

wally world has some cheap foam for bicycle H bars that will slide over the foot pegs.

[Dofin]

Firstly, got it the handle bars are mounted in rubber bushings. 

Interesting about the crash bars, I have not added crash bars but did add a center stand.  The Thump was there before I installed the stand. 

4.5K would put me pretty close to 80mph.  Dont want to run that fast.  Again I want to be sure you guys with recent V7s run 70mph in 4th gear on the highway??    It doesnt matter if I am in 4th at 70 or run 80 in 5th I still have the uncomfortable thump in the bars.  The buzz type vibration is acceptable in all operation speeds.  I think it is odd that I would have to run in 4th gear at 70mph all the way to Alaska from Pensacola??? 

Can we switch the oil conversation to the oil post I started?  thanks

I've made plenty of isolation mounts for motorcycles, mostly handle bars. Here is one way for round tube type bars.

Those #24 in the drawing are half measures, they could be made far better and work much better too.

Two places to put them, as isolation mounts for the bolts going into the top triple clamp or spanning the tube as it is captured by the bar clamps.

There are other ways though.

For the bolts holding the lower bar clamps going into the triple clamp. Drill the threaded portion of the triple clamp (where the bolts go through) or enlarge them if they are through holes with bolts held by nuts. Before you drill them out get bushings the diameter of the original hole. Drill the hole out to a greater size.

Cut the bushings to a slightly longer length so that each end of the bushing extends past the top and bottom of the triple clamp. Insert the bushing into the hole keeping it centered and the bushing end slightly above and below as described above.

Fill thegap between the bushing and hole with a rubber of appripriate durometer to give the isolation you need. It must be a very tough material, not soft. Allow to cure. Alternatively just fill the gap and bushing, drill out bushing afterwards.

Now when you insert the bolts, the component (bar mount) get tightened to the bushing, nothing above the bushing touches the triple clamp. The bar holders ride effectively in the isolator.

There will be some flex but how much depends on how much wider the hole was made than the original and the type of rubber used.

They can be made very thin yet effectively reduce most vibration.

BTW, this is how Moto Guzzi does it, in essence but they might press fit their mounts (Norge 8V)

The other way uses the bar tube where it is held by the top clamps to do the same thing. You need an extra set of bar mounts. Treat the tube as the bolts in the above example and use larger bushings inside of the larger bored hole ofnthe top and bottom bar mount. You can use split rings to do this. Much easier than splitting a bushing.

This way you aren't boring larger holes into the triple clamp. The big difference is how the isolators affect the feel of the bars and how easily you can experiment with different durometer rubber.

3M makes suitable materials for making isolator mounts.

The same ways can be used for footrests.

Done properly, the bars don't get that flexible feel to them but vibes can be reduced to nearly nil over much of the engine rpm range.

But then it won't feel like a V7 anymore either.   

Oops, back to the oil.

 :Beating_A_Dead_Hors e_by_liviu       Okey Dokey, thanks everyone for the inputs.  I think much like Rocker59 and RSS29 the the V7 just thumps cause it does not have the additional internal balancing that some of the more refined new bikes have.  I like them now believe they were not ment for LONG distance, I will figure out what I need to do ether way.  Thanks so much for the input and interesting opinions. 

Time for me to move on and let you folks help some other need person?    

Woop, Woop!  going riding in the morning!!  Oh yea, Last Saturday I took my brother out for a ride with his new to him 2013 Yamaha 1200 Tenere.  start at 7am breakfast break at 9am road all around lower Alabama, stopped at 1pm for bbq lunch. got back home at 4pm, 320 miles.  Great day riding, very seldom over 65mph on the country roads, he fell behind the V7 in the twisties but of course caught up in the straights!
