So I have been sitting on my new 1100 classic all winter. It finally got above freezing here so I took it for a rip. The sound is fantastic but she is running lean and backfiring a little. I went to order the jet kit and the supplier recommender hyper drive or at least better air filter as well. Any recommendations would be appreciated. i dont really want to buy a hyper drive i am not a big believer in them as far as improving performance but would love others input thanks.
