I just installed some Yoshimuras and they are fairly loud at cruising speed.

A wide rear tire my increase your testosterone levels but the bike won't perform better. I like to replace tires that match but a different front tire won't put you in a ditch.

1. So if the slip-on is louder than I prefer and I go with a stock setup would I need to possibly rejet then or could I potentially remove the snorkel and allow the rejet to stay? (Rejetting just so I know what I actually have is an option as well)

2. I'm not much of a "hey, my tire is bigger than yours" kinda guy. Since the bike came with the 150 I guess my question should be "is the performance/ handling of a stock bike worth throwing out the fairly new 150 tire?"
