GL1800 DECELERATION VIBRATION

Postby targhee dick » Sun Aug 12, 2012 9:03 pm



I have a 2010 GL1800 trike. Coming back from Sturgis, I noticed a vibration every time I decelerated either going up or down a hill. I am at a loss as to what could be causing this. I feel it in the grips and on my floor boards. It is only a momentary vibration right after you let up on the gas. I sure could use some help on this one. thanks

Have someone check out your steering head bearings.

Thanks for the input. I will have that looked into. Never thought about that being a cause of the vibration, but what the heck, it's worth a look see.

Just my $0.02:
In my experience (automotive vibrations diagnostics and corrections,) deceleration vibes can very often be attributed to loose drivetline components...if it were a car, I'd suspect either a front CV Joint or axle (fwd) or a U-joint/driveshaft issue (rwd.) To help diagnose this problem, get your bike up to speed, decelerate...as soon as you feel your vibration, open the throttle back up. If your vibes go away, I'd wanting to have a look at the driveshaft/u-joints.
Keep the rubber side down.

Just had my driveshaft replaced one week ago. All shake deceleration and 40 mile shake gone. the bearing cap on the ujoint
was broke. It has supprised me that all the shakes are gone.

Roger that Jinx, I did find my problem, and it was the splines on the intermediate and main shaft were completely shot. CSC is sending me a whole new shaft and all that goes with it. Putting it in is not a problem at all, about 20 minutes. Hopefully my vibration will also be gone.

Well ****,
I finally got my bike back.Well over a MONTH .I was not happy.They had to redo it 3 times to get it right.Since they did not put out a full recall,I wonder how many people are going to get stuck with the bill on this one.If I had not seen your,I would have just took it in to my shop,and got it done.Prob be about $ 800.I had 3 calls from out of state Wingers on this,that did not know about the recall.Told them to let any others know about it.Also wtote Stu at Wing World About it.I,m not on any kind of a crusade or anything,I just think CSC is being very unfair about this.Alot of people are going to burned for a big bill.Not a warranty issue iether.It,s an engineering failure,and possibly a safety issue.Mine failed in the middle of a busy intersection.What if it happens on the hiway with an 18 wheeler right behind you ? I think those of us that caught this should try to pass the word !!!

Hey Ancient One, you thought that you had a problem at an intersection, check this out. After I got me new shaft, I had to take it to Seattle to have it installed. While I was there, I also bought a camping trailer for my trike. They got it all welded up, and my wife and I started back to Coeur d alene in the late afternoon. Going through the mountains, I discovered that it was still vibrating. In addition, about eighty miles from home and 10:00 pm on a major highway, my bike quit. Long story short, it appears that I had a faulty oil pressure sending unit. They told me that when it reads too low of pressure, it shuts my motor off, which it did. We had to sit in a parking lot from 3:00am to 9:00am waiting for the shop to open. I called the installer in Seattle the next day after I got under the bike and say that you could see the splines on both ends. They apparently did not fully extend the shaft during the weld. I had about 7/8th of an inch of spline on the main power end, and about an inch on the rear. So he came out with a trailer and picked it up, and delivered back when it was done. So now it seems to be running ok, I got to ride it for a couple of weeks, and then had to put it away before the white fluffy starts to fall. I hope that we don't have to write about subject again. Hope all is ok on your end. R.

Glad that I could do something to help the cause. Maybe CSC will see some of these blogs, and have a change of heart and do the right thing. Anyway, hope it all goes good for you. Talk to you in the spring, when we take the bikes out of their cacoons. talk later. r.

HEY ANCIENT ONE. I THOUGHT THAT I WOULD DROP YOU A LINE AND TELL YOU THAT I FINALLY GOT THAT DRIVE LINE PROBLEM SOLVED. I BOUGHT (NOT CHEAP), A NEW DRIVE LINE WITH A CV JOINT ON THE END OF IT. I FOUND OUT THAT THERE IS TOO MUCH STRESS ON EACH END OF THE DRIVE LINE ON THE SPLINES, DUE TO THE OFFSET GEAR BOX. THIS CV JOINT TAKES CARE OF THAT AND THERE IS NOT STRESS AT ALL ON EITHER END NOW. BEST OF ALL, YOU CAN TAKE IT OUT IF YOU NEED TO DO ANYTHING TO IT. CANT WAIT TILL SPRING. ANYWAY, IF YOU KNOW OF ANYONE, (AND I AM SURE YOU WILL HEAR OF SOMEONE), LET THEM KNOW THAT I HAVE A NEW RUBBER COUPLING FOR SALE IF THEY (NO....THEY ""WILL"" NEED ONE TO REPLACE THE CRACKED ONE) MENTION TO THEM THAT I HAVE ONE FOR SALE. LATER. RICHARD

Mine's not a trike, so this will help everyone on two wheels (and possibly those on three). The cause of the nasty head shake that comes on really strong at deceleration at about 40mph is caused by rear tire cupping. When the rear tire is cupped and as you decelerate to about 40 and below, the rear tire is going off and on the cupped and non-cupped parts of the tread. This is sending a shimmy up through the frame, and the front end is the place where the energy shows up and gets released.
