Knocking from front end
Hi my wifes 250R has developed a knock from the front end that you get over bumps and feels like the head bearings or front forks When it does it, it feels like something is broken or missing I put it on the front paddock stand and checked the front wheel bearing but that seems fine. I can't feel or see anything obvious. Has anyone had a fault like this? Her bike is an 08 with 4.5K miles on it, she has had it about 6 weeks.

with the bike up on a front steering stem type stand, grab the front forks and try to wiggle them front to back and side to side to check for play.
have you checked the fork bolts that hold the forks into the triple clamps? |

Thanks for that. I know I need to do it but it's getting round to it all I usually do is have a quick look at the site a couple of times a week and that's it

Hoping to get a chance to look at the bike tomorrow evening all I have though is a standard front and rear padock stand. A mate might pop round as well so we will see if we can spot anything!!

if you don't have a steering stem type lift, you can lift the front end of the bike by some rafters of your garage roof, if you have some, using the handlebars as attachment points for hanging.

Good news the knock is cured. The centre steering stem nut was loose, torqued it up to 40Nm and its nice and quiet. Hopefully the head bearings haven't been damaged

okay, thanks. how loose was it? any idea why it was loose? had the bike had work done to it previously?
sorry for all the questions... I think this is the first time I've heard of the stem nut being loose on the 250 plus I have a front wheel wobble that I'm trying to track down on my bike. |
