front / rear wheel alignment 1/2 inch out

Post by hotrodpearl » Tue May 15, 2018 8:38 pm



Help....Please....Anybody got any ideas on aligning my 2006 GL1800 . It has a weave between 20 and 50 MPH , nothing violent but definatly annoying . I bought the bike from the orig owner with 80,000 miles quite cheap which should have been my first clue....... The body is basically flawless and it runs great but was weaving . I changed the steering stem bearings to all Balls tapered roller bearings , replaced the tires and rear wheel and front wheel bearings and checked the swing arm for lateral freeplay and any loosness. Previous owner had installed a fork brace , Traxion triple tree and upper fork brace and progressive front springs all in an effort to deal with the same problem I believe . So when all this yielded no improvement , I propped it up on jack stands and measured the rear wheel to front wheel alignment and found the rear wheel tracking a full half inch to the left of the front wheel......SO the front wheel needs to be moved a quarter inch to the right to track straight....OR the rear wheel needs to be moved to the left a quarter inch for it to be aligned ....Does anyone have any Ideas or have I missed something.........Can one of the forks be dropped lower in the triple tree to move the wheel over ???? MY REAL PROBLEM IS I CANNOT GET IT TO PASS THE SAFTEY INSPECTION WITH THIS PROBLEM SO I NEED IT FIXED OR ELSE I HAVE AN EXPENSIVE PARTS BIKE............. I'm not a novice but not a pro either and have owned 8 or 10 Wings and never ran into this . Can find no evidence of a crash on the bike or in searching Insurance sources.....Thanks for any help : )

after some assistance and more accurate measurements we determined thet.......I was wwrrrong .....the alignment is only out 1/8 inch so that's not the problem......which is even more disturbing because now again we have no idea what is causing this weaving and still can't get it inspected or licenced.......Ideas....??????????

I know nothing of Canadian laws but I am curious, why is it that you can not get it inspected or licensed? Do they ride the bike as part of the safety compliance? I know of no other way to detect that there is a "weave" as you ride.

Weaving can be caused by having the steering bearings too tight.

Weaving/head shake/shimmy can be caused by a ton of different things - basically anything that is part of the suspension or wheels that can move.

- Incorrect suspension geometry
- Damage causing tracking misalignment
- Swingarm pivot free play/worn bearings/incorrect torque
- Worn wheel bearings
- Worn steering bearings
- Steering bearings torqued too tight/too loose
- Tire runout/wear/defect/incorrect pressure
- Wheel damage/runout
- Incorrect suspension preload
- Fork wear/bushing wear/free play
- Rear suspension free play/wear
- Aftermarket additions altering body aerodynamics, including windshield
- Imbalance in carried load/overloading

Incorrect axle/fork pinch bolt install/tightening can also cause a slight twisting of the forks which will look like misallignment and can also cause weaving, and stiction of the front suspension.
