For about 3 years now and some 25k miles I have been trying to determine why my '99 LT runs rough when the bike is leaned even slightly left. It's most noticeable at idle, dropping about 100 rpm's, and it can also be felt at road speed. It runs perfect when it's straight orleaned right. It's not affected by the fuel level. It has 71k miles and has been well maintained. No other issues. I've asked 3 dealers and have been told they have not seen this problem on another bike and it's not so bad that I want to spend a grand on diagnostic service. I've test run other LT's and they did not have this problem. I'm wondering if anyone else has noticed this problem on their LT and if there are any takers on what might be causing this. It's not a major thing, more of a curiosity. Could something be going on with the oil or oil pump? The level is where it should be - never over or under.
