about a month ago I tore the bike down to just frame and left the engine in. Kind of a pre summer inspection... ok maybe a little more then an "inspection" lol
Replaced quite a few little parts (bolts, nuts, springs etc) and I did have to replace throttle body with used one from ebay. I stripped my buttery valves on the old one.
I completed the rebuild just a little bit ago. I let the fuel pump prime about 4 times before starting. Fired right up for a second, fired it again and she sang beautifully. I only let it run for a min because I was trying to let new fluids cycle and top them off and 3 weeks worth of PB blaster was burning off the exhaust header.
After shutting it off and fuel cap closed, massive amount of air came gushing past the cap seal. I opened it up real quick to help it exhaust out (it was alot). I let the tank breath for a min, it has been sitting in the corner of my hot garage for a couple weeks so I figured vapors finally found a way out.
Came back a few mins later and closed the cap, raised bike off kickstand to push into garage and instantly started gushing again.
Would I be correct in assuming it's just trapped vapor build up? Or maybe something to do with the used throttle body I should look at?
I'm 99% sure all electrical and vacuum lines are hooked up correctly because I labeled every single line with blue tape and only removed the tape after they were plugged in.
