It is probably your jets. I have a hawk. Looks like the same engine. I too have the mikuni carb. I am currently running a 27.5 slow jet and a 115 main jet. Runs like a top.
as far as the valve adjustment. Pull the spark plug. bring it to top dead center. the line on the stator will be in the window on the left side. Both valves should be fully closed now. If they are not you need to turn the engine over again. Ok. Both valves are closed. Take your feeler gauge and try to place it between the top of the valve and the rocker arm. If it goes in and their is a slight drag you are done. If not, loosen the nut on the rocker arm and then move the screw down until their is a slight drag. Tighten the lock nut. Recheck the clearance. I believe the valve setting is .05mm or.002in. I set mine at .003in. loose is better that tight up to a point. |

6000 foot mark. I like to use a #30 slow jet at sea level; it makes it a bit tough to start in hot weather, but it's easier when it cools off. A 115 main should do the trick for you. Show us where those two hoses lead. I'm guessing that one goes to the crankcase vent and the other to the AIR valve, but I'd like to be certain. The video you linked is for a pushrod motor, but that doesn't matter. Just follow the instructions blanc12 provided and let us know how it worked for you. I'll add that it's easier to turn the motor with a breaker bar and socket than it is to use a ratchet. Also, only turn the motor counter-clockwise, as viewed from the left side. When you line up the T mark in the viewing hole, you should be able to wiggle the rockers. If not, turn the engine one more complete rotation.
