Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

Front end bent !?

Post by ZekeVal on Sun 10 Sep 2017, 9:01 am

I've noticed over time, especially on longer rides and straight roads that my left arm felt more "elongated" than the right. I really became aware of it on my roadtrip where I could actually see that the top yolk seemed off, with the left fork cap looking to be above the right one (yolk tilted to the right) while going straight.

It hasn't stopped me from riding 18,000km with the bike, but it just gets annoying, especially since the bike didn't have any major accident (few drops at standstill, and a light rub with a camping van). 

The visual impression suggests that the handlebar is not bent and that the issue lies somewhere else (which is all the more worrying...).

Here are 2 pics to illustrate a bit:

The first one shows how it looks like when it feels straight (from handlebar feel and visual impression)



And the second one shows the front end when the bike is going in a straight line:





My only explanation is a bent fork or worse, the frame?

Any input appreciated.

Don't despair. It is probably just that your forks have twisted in the yokes.
Loosen the pinch bolts holding the forks, the wheel spindle and the mudguard bolts. 
Make sure that the bike is supported ideally on it's main Stand with an assistant sitting on the passenger seat to take the weight off the front end. 
Tightening up the bolts starting with the wheel spindle and working your way up normally straightened everything up.
Sometimes it needs a bit of persuasion by holding the wheel straight between your knees and moving the handlebars until it's all straight.

Thanks for the advice! I've done a version of that but I just loosened the yoke bolts. Will definitely try loosening everything.

Also, I didn't mention that I changed the oil seals and some internal components on the fork recently; I may have failed at putting it back straight ><

Hopefully I'll be just as simple as that.
