I have an 89 zx7 H1 that I have been working on. It sat for about a year until I bought it. It had old gas in it and needed a tune up badly. I started by getting new spark plugs, changing the oil, and changing the coolant. I then cleaned the carbs spotless and cleaned out the fuel tank. I have got to a point now where the bike runs pretty good but it still isn't quite up to my standards. It idles great, if i turn the throttle slowly it will rev up fine. but if i try to really gun the throttle to go fast, it bogs down quite badly and my overall throttle response is horrible. I have the pilot screws set at 3.5 turns out. And I have the needles set at the 4th notch from the top. The bike runs better and better as it gets hotter. Am I running too rich or too lean? It's very hard to tell as the spark plugs are brand new and don't really show any signs of discoloration yet.
