2014 Buzzy Bars

[DHS1981]

My new FJR gets really buzzy in the bars in 5th gear at about 4000 rpm -- around 70/75 mph. Coming from a V-Strom 650 and a GSX1250FA, the FJR is significantly more buzzy at speed than either of those bikes. Is this just an FJR thing that I need to get used to, or cause for concern? I put on grip puppies hoping to dampen the vibes, but without much effect. The only mod I've made that could possibly impact vibration is the installation of R&G frame sliders. Since I am still breaking in the bike, I haven't gotten it up to 5000 rpm and beyond, so I don't know it it smooths out at higher revs, but the 4000 - 4500 range is where I will likely be during most of my highway riding. If this is just an aspect of the FJR, is there anything I can do to lesson the vibration in the bars?

If your frame sliders mount to engine mount bolts it is critical to retorque these bolts to spec. Also, I believe I have read on this forum that one side should be torqued before the other.

Search the forum for info on this, or maybe a better informed brother will comment.

Take a look at this post - https://www.fjrforum.com/forum//index.php/topic/127669-buzzing-foot-pegs/?p=725958 for the definitive "how to" to correctly, AND IN ORDER, torque your engine mount bolts.

Poorly/improperly set/torqued motor mounts will definitely cause some buzz. However, the FJR DOES produce some high frequency buzzing in the rpm range you're talking about. Has actually driven some folks away from this platform, while others, such as myself, couldn't give two dukes about a little vibration.

pretty sure it's the engine mounting bolts...installing the sliders can cause problems. Torque is critical on those bolts. I learned that the hard way with 2 different FJRs. Be damn careful torquing the bolts, as they will strip quite easily.Good luck.

Thanks all -- I will take care of the sliders. I torqued the bolts as prescribed by the slider manufacture, but in no particular order; maybe that's where I went wrong. As I recall, it was 30 ft lbs. Do you know what Yamaha says the torque is on the engine bolts?

 

[DHS1981]

Great info at the link -- thanks RadioHowie. I see that the torque is supposed to be 35 ft. lbs. -- I think I torqued the frame sliders at 30. I'll loosen everything up and do it again, with the left side first.

 

[RadioHowie]

35 lbs/ft.

Just remember, on the right side bolts, loosen the pinch bolts on the frame spars first, tighten the big 'uns to 35, THEN tighten the pinch bolts.

If the vibrations remain there,uninstall the frame sliders for a while,and ride your bike to see if something has change.

Heavier bar end weights are one way to help with bar vibes if the slider fix does not work. I had them on my 2004 and it helped.

 

[DHS1981]

Will do. Thanks all for the great advice. Has anyone installed hand guards, and if so, did that dissipate the vibes any?

The V Strom guards are the most common it seems...and I don't see how those would dampen the vibes as they are too light (I have them). The bar-end weights are probably your best best, but vibes are somewhat normal in the range you speak of.

My bike had Throttlemeister bar ends on it already when I bought it used so I don't know the difference over stock since I've never taken them off. I notice very little vibration in the bars at any RPM with this setup.

+1 on the engine bolt torquing.

Doesn't TBS affect engine vibes? Haven't I heard guys sayin' that synching the TBs smoothed things out? Any chance that throttle body synch may be out on a new machine?

Took off the sliders; put the stock bolts back in and torqued to 35, left side first. Will ride and compare. Looking into heavier bar ends. Also, has anyone had recent experience with the Vibanator bar ends? I've read a lot about them on the forums, but nothing really recent. Some people swear by them.

Oh slap.. Yet another failure of a once thought highly platform..


Come on mama Yama.. R U ever gonna fix this hunk of ****?

Has actually driven some folks away from this platform, while others, such as myself, couldn't give two dukes about a little vibration.

I also decided to re-torque the engine mount bolts as I too feel pretty remarkable buzz on footbegs, the same way as stated earlier, at around 4000 rpm. I also consulted the Yamaha Service Manual (pg 5-6, 5-7) and the tightening order was a bit different there. According to it you should start

1. The upper left side frame spar bolt, 35 ft.lb

2. Right lower side bolt above the foot peg, the torque is 32 ft.lb, not 35 as for others

3. Right engine mounting nut on the bolt which goes through the engine, torque is again 32

4. The lower left side frame spar bolt, 35 lb

5. Right side upper frame spar bolt, 35

6. Right side lower frame spar bolt, 35

7. All 4 pinch bolts, 17 lb

By the way, when taking off the right side fairings, I found a plastic piece which seemed to be loose from a metal thingy. Any idea if there should be any screw or something? I zip-tied it just in case.

The vibrations come from the engine,i believe that all the fjr have these vibrations.I rode five fjr until now,all they have the same vibrations.I strongly believe that the problem become from a bad design in the two balancers in the engine,as a bad design in the clutch house...(dry clutch plates).We must live with those vibrations..!And with the dry clutch plates...

Really i don't know why the mama Yamaha she didn't improve these problems....

I've had three FJR's (one of each Gen) and I think your accusation of bad design is complete BS. Get your bike up to spec on the balancers etc. or buy something else. Of all the things it might be, bad design isn't the cause.
