New 2014 Honda 400x very very happy!

I finally got my first Honda. After riding for 2 days on her I don’t think its possible to be happier with a machine. Awesome low torque and traction made for great technical riding. I haven’t hammered it yet, still breaking it in tho. You feel spoiled with reverse and it has looks to kill lol. Beyond that one issue is a cold start with the 400. Choke or no choke it coughs until warming up enough to idle. Which isnt really nice. A lot of forums talk about that so I ordered up a larger pilot. 40keihin instead of stock 38. Also I ordered a uni filter, 1 tooth lower front spkt, and the gn4 oil/ filters. I also ordered a 152 keihin up from a 148main jet. My question(s) would be do those jets sound appropriate with a full stock quad except an air filter, and also has anyone used a DG bullet exh. On the 400? What a baaaad looking pipe. Anyway anyone looking at a sport quad that begs for more, look no further. Granted I’m not cranking gears at redline. Thanks everyone on here, for all the useful tips and knowledge/opinions. 1 more thing can I upload pics and post them from a cell phone? I only was able to get a profile pic up.
