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.

I don't really know whats causing you carb problem, but I do see another issue that you might want to address. If you are running all those mods (slip on filter, rejetted, cut carb spring) and you still have the stock exhaust on the bike you are not getting the exhaust flow that you need. The stock predator pipe is way to restrictive for the changes that you have made. Have you tried putting the stock pilot jet back in? Stock is 45 and the jump to the 50 may be to much for it. That could be your hesitation problem when blipping the throttle because the pilot jet controls the idle to 1/4 throttle. I could be way off on that, but I seem to recall reading that somewhere.

My bike did it with the stock 45 in it. Thats why I decided to try the 50. Changing the jet made no real change. Could it be a float issue? I also read some things about the slip on feeding the carb turbulent air, does that have anything to do with it?
