I was curious whether the weather impacts performance after a Dyno tune. I had the bike tuned with an stage 1 upgrade in November. Used all HD parts and tuner because of EPA settlement. I think the bike is running rougher now that the outside temp and humidity are different. Do I have to go in for another $500 tune to make the bike run smoother? I do not want to buy an after market tuner because of warranty concerns. Any thoughts or suggestions? Bike shakes more at stop lights and just sounds rougher. (Of course, that may not be a bad thing:wink: Thanks.
