Good afternoon everybody. I've had my GS500F about 5 weeks now, and have ridden almost every day, in all conditions since day one (which is totally not what I expected given how rubbish I was at my test, and that I didn't get a bike until 2 months later). All good. Apart from last night. I stopped on orange where I should probably gone through, but I'd only ever had to stop quickly twice before and it was a what made me fail the test the first time, so I thought it would be good practice. Lo and behold, the rear steps out, which was uncomfortable, but I caught it fine. It took a good kick of the gear lever to get it into first again, but aside from that I thought no biggy, but checked my tyre pressures just to be safe. So the rear was at the recommended 36, and the front was at 29 instead of 33 (which always seems to be the case - slow leak?). Anyway, riding to and from work today, it feels like the bike is moving sideways under the rear brake, but there is no damage at all to the tyre and it didn't lose any air (checked this morning too - front was fine, seems to take a week to get down to 29). Is it all in my head? I've been having a ball, but have been sensible with the exception of last nights impromptu self test, but for the first time since buying it I haven't felt confident and unsafe (traffic has been very good to me - dare I say it the only ******** behaviour was some guy on some black bike on Dandenong rd who passed me in my lane at about 110, standing up and hands off the bars!). Any ideas (assuming it's not just in my head) what might be causing it?
