OK here's the deal. I have a slip on K&N, stock exhaust, dynojet kit(170 main jet, needle on 2nd slot from top), and I drilled my slide and cut 5 coils off the spring. I have the 50 pilot jet on the way. Well this is my problem, when I wheelie the bike real slow in 1st gear it hesitates when it get it stood straight up in the air. I'm takling about doing a wheelie at like 2mph just burping the gas to keep it up, as soon as it gets all the way up in the balance point I blip the gas and it falls on it's face then once the wheels are on the ground it's fine. Rippin in 2nd and 3rd I can stand it up for miles it seems with no running problems at all, it only does it when I'm in 1st trying to go real slow. Can anyone please help? Thanks in advance.
