Sorry to leave you guys in the dark for these past few days. I haven't had a chance to even see my bike much less work on it. Darn job getting in the way of my fun lol.

donald:
Yes I have the shop manual
At this moment I'm not too worried about the carbs being the problem
I first did a compression check and found i had 30psi on the #1 #2 and #4 cylinders and 100psi on the #3 cylinder i did a  leak down test and had air that leaked out of the exhaust and intake so i decided to  eliminate  valve timing from the equation and i took off both cams. I then re did the leak down test and had air still leaking out of the intake.

so now that plan is to find a strong friend to help me wrangle the engine out and back up on the stand so i can pop the head off and figure out how i messed the valves up.
