I took apart my bike to repair second gear. I put the bike back together and it has never ran the same since. I have a stock exhaust and no power commander. The bike is running rich and loading up with fuel. I've checked sensors and there is no warning light on. I put hotter plugs in it and it seems to be doing a little better but it isn't like it was. Do you have any ideas or seen this problem before. When I grab the throttle from idle it like to bog, it blows a little smoke the takes off like a bat outa hell. I also would like to know how much vacuum the hayabusa is suppose to have at idle.
