As I'm working on my first bike ever and have limited experience, I have to ask.
My '89 DOHC (6 speed) is currently running quite well, starts and idles nicely since I cleaned the carbs properly and put in a new battery and spark plugs. It's mostly stock, no pods or different exhausts. Air filter is clean.
My problem now is that my top speed is about 110 km/h (which is 68 mph) which I read is a bit on the slow side. I should be able to get to about 88 mph. So my thought is, there has to be something that is not well adjusted.
What is the most likely culprit? I've read about our bikes running slightly lean in stock settings, is this true? And how would I enrichen it? I haven't gotten around to checking my valve clearance yet, would that help much?
Also, I've experienced some instability at certain speeds. It kind of sways left to right when going around 20 mph. This has improved since I've change my front fork oil, but it's still noticable. At higher speeds it's not really there, so I'm not too bothered. I've checked my steer bearing (what do you call this, the bearing between the front fork and the frame) and it's tight, there's no wiggle room. Also my tires have been replaced, and this problem stayed. Where would I start looking for a cause?
Hope you can help!
