Front Fork Noise and Wobble
Ok, here's the deal.. My 2011 runs great, love it, couldn't be happier. However there is a small leak in the front left fork. The mechanic said it wasn't a big deal and not to worry about it. Having said that, when I hit a bump the front end makes a pop noise and the bars shake a little. Under semi heavy breaking the front end shakes a little. I'm wondering what may be the issue here? There are no problems when riding, only the loud pop and wobble with bump and wobble with breaking.
Any Ideas? Side note: the wobble/shake isn't from left to right, it's front to back. If that makes a difference. Last futzed with by NinjaNoob23; May 21st, 2014 at 10:06 PM. |

Could be that your steering stem bearings are loose. You'll need to remove your top triple clamp and get a spanner wrench or a flat head screwdriver and hammer to tighten it up if that's the case.

Could the noise be from low oil in the shock itself? |

Yes it is an urgent fix. If you hit a bad bump at speed you might get a tank slapper. You don't wan to chance it.

I took it all apart last night and found the problem. The bearing nut was a little loose but not enough to cause a problem. The leak in the fork seal has gotten a lot worse since the last time I checked it (less than a week?). Sooo now I get the pleasure of tearing the front forks apart to change the seals
Here is a good DIY write up on seal replacement. https://www.ninjette.org/forums/showthread.php?t=23200 Last futzed with by NinjaNoob23; May 23rd, 2014 at 06:02 PM. |

You could try this out first. If its just dirt trapped between the seal and the tube, this would work. Or you get clever and make your own.
