I've ridden it a few times but I'm experiencing a couple of issues which I'll try to describe to the best of my ability. First issue is the amount of smoke coming out of exhaust its white it's smoking really bad as the RPMs get higher. 2nd issue is when I'm going up a hill Im not talking a big hill just a little hill (has to be under 15% grade) it'll start off fine but then it's like I lose the power I should be getting and it struggles to make it up the hill I can pedal and it helps thats how slow I'm going. 3rd is I am leaking from my air filter not terribly bad just drips a little bit. I do not have stock air filter I have this http://sickbikeparts.com/4-stroke-air-filter/ so maybe this is causing some issues? A person in comments talked about having to drill jet size bigger is that something I should do? Thanks
