I have a '93 ZZ-R250 with about 80thou on the clock. Normally a pretty reliable bike and it gets me around. Two issues I have noticed lately however: First the brakes. Back brake takes a lot of travel before it engages. Front brake seems not to engage for the first 1cm or so of travel and then bites very hard (hard enough to make the front dive in an annoying fashion at low speed). The lever almost feels "rusty" in that the travel is not smooth and the reaction of the front brake at various points in the lever travel are different. I'm considering a fluid drain and replace + new front and back pads. Would this fix the issue or could it be something else? The second issue has to do with fumes. If you ride the bike for any significant amount of time (a few minutes plus) you end up smelling like fuel and/or exhaust. The bike doesn't appear to leak fuel (I've checked with the fairings off) and I cannot see any obvious place where the exhaust could be leaking. I know this phenomenon is not normal as the '07 ZZ-R250 I had did not do this. Thoughts?
