Hey guys and gals!
I need some help figuring out what is wrong with my handeling.
I have an 04 R* and she wanders in the lane. Tire pressure is 39 front and back.
Try a lower pressure especially up front. As I recall, the frame sticker says MAXIMUM pressure up front should be lower than 39 (I think it's either 33 or 35). Rear is 39 max, I believe. Too much pressure can make a bike seriously squirrely.
Experiment with different pressures, it's easier than all the other fixes suggested here and just a couple PSI
can make all the difference. I find 28-30 makes the front of my bike feel more stable. I'm a light rider (160lb) tho, you may like more or less PSI. So far after 6000 miles my front tire hasn't worn funny wit the lower pressure.
