the valves are one mm over stock dont know name brand,i had it dynoed at hucks racing ,the reason i think it is rich is because i smell lots of raw fuel and has a lil gas smoke out exaust we set the air fuel ratio around 11 to 12 % he thought that was pretty good. but as far as the richness i can run my valves and it helps tremendously with that.i dont understant why they keep tightning back up.i run the crap out of it when we ride ,i also havent had a chance to put my clutch kit in yet ,talked to u a while back and u told me that might help with the busting up at low speed ,i really need to bring it to ur shop and let u get er fixed . its hard to dianose on computer with out actually rideing to see what its doing .i really appreciate any info u have .

yes sir it has the works just standard.last night i let it idle a while and i could hear the clutch doing somthing and it would make the engine hick up for a second .the thing runs great just got to get it dialed in.
