On the right side of radiator the big hose under the rad cap, it seems like it is building pressure and the hose is swelling which causes it to leak out a little....any idea what could cause it?

The bike isn't overheating though, sometimes it leaks around 180 degree's sometimes around 215. Rad cap looks brand new, I ran it with rad cap off at first didn't see any air bubbles, put the cap on went for a 5 min ride or whatever I come back let it idle and it starts to leak out the top of the hose. Shut the bike off, after a minute or 2 the pressure goes down and it stops leakin.

The hose is clamped down tight, not sure what is causing it, I can go for a ride come back and its fine. Then next time I go out it leaks.

maybe a bad hose?

Try cutting the last 1/4" off the hose and putting it on further with the hose clamp in a different position?

thats what did tonight, I cut it where it was clamped before, moved it up and tighten it down on a fresh piece of hose. still leaked.

I had a friend with a gsxr 600 that had head problems and it created pressure in his line. Dont ask me how it done it. thats what the mechanic determined. I hope its not your problem good luck.

Are you sure there are no cracks anywhere?

yea I can see it coming out the top of the hose

yeah I don't think its anything like that, I just changed oil and its clear no rad fluid in it, I wouldn't be surprised tho this bike has been a nightmare.
