I'm going to be riding my brothers 1993 Ninja 500 for the summer. I rode it last weekend, and am going to bring it home this week.
Heres the deal:
It has a leaky tank/petcock which has been dripping gas down the fairing for a couple of months (eating the paint). It ran fine and was not leaking in March when he rode it last. I rode it on Saturday (my first time on a street bike) and I thought it ran ok having never ridden it before (or a multi cylindered bike, for that matter.
After getting used to it a bit, I noticed it starts to pull really well and smooth after about 8000 rpm. untill 8k, it seems rough and powerless. If I roll on the throttle at 3k, it is rough untill 8k, where it seems to catch (almost like I turned the choke off or something) and start to "scream".
I didn't notice this at first, since I was getting accustomed to riding again, but now I am sure there is something wrong. I was wondering if the leaky petcock has something to do with it. I havent looked at it yet, but the guy at the motorcycle shop said it was vacuum controlled. I have no idea how it works, but it seems that this would be fuel or vacuum related. I tried searching the posts but could not find this question answered. Also, the bike starts and idles fine.
Thanks in advance for any help
