Point well taken. I guess I need to seriously consider if I want to retune the bike or risk a gurgly, goofy detuned situation. I truly don't have the knowledge to tune a carbureted engine. For now, I've ran a fuel system cleaner through it in case there is any water in the tank. It already seems to be running smoother. Sent via BlackBerry by AT&T

When a bike sits up a lot (yours is 15 years old, with only 12,000 miles on it -- indicating it hasn't been ridden a whole lot), the volatile organic compounds in the gas evaporate, leaving behind a syrupy sludge that clogs the passageways in the carbs and prevents them from doing an efficient job. It's a typical scenario for any old bike and probably the reason yours is not idling/performing properly. The remedy is a thorough and methodical dismantling and cleaning of not just the carbs, but the petcock and gas tank as well. The plastic airbox and its filter are less critical, but in stock form they are designed to work together to provide just the right volume of air to the carbs. If you introduce more air -- as you would with a free-flowing filter like the K&N -- you risk upsetting the fuel/air ratio the motor needs, maybe even after rejetting. So, using a K&N, with no other modification, is not automatically a good thing. Neither is rejetting, unless you know what you're doing. Even then it's a fiddly, experimental thing, requiring a lot of tweaking. Not trying to scare you away from pursuing it, just tossing a little practical reality into the mix. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
