For gas run the BR8ES. You can get them for like 2 bucks each at pepboys, autozone, ect. dont get them at the dealership, they rip your shit off for them.
For the gap i want to say its like .023 but I could be wrong. depending on what mods you have is going to depend what jetting but you should be around the middle clip, 310 main, 27.5 pilot, air screw 2.5 turns for a bike with aftermarket pips and the airbox lid off. it might be a little off but it will get you very close.
