I have read other members problems with jetting, but still I am not clear on what I should try for my problem. On deceleration my bike pops a lot, I am at 5000+ altitude. I have a 178 main and 42 pilot, the needle is in the stock position and the fuel screw is at 1 1/2. I tried to bump the pilot to a 45, but I could not start it afterwards. I was thinking of richening the needle by one clip, do you think this will help. Thanks ahead of time.
