that sounds shitty, any way to check the head for leakage maybe without having to tear it apart?

My bike runs mint the first few minutes or if I let it sit for a few minutes. but when I slam the throttle it sounds like it's drowning in air and then it kicks in. Also seams to have low idle power. I put lucas fuel injector cleaner and it ran good for that tank but now it's back to the same damn thing. I'm gonna try the injector cleaner again and see what it does.. let me know what you find I'm working on it as well.

injector cleaner is also on my to do list, havent figured anything out yet..
