I got a 07yz450f and the guy that owned it before me busted the waterpump cover and then instead of buying a new one he siliconed the crap out of the busted one and when I got the bike first thing I did was replace the pump cover and the gasket and the y pipe an gasket that connect to ure hoses that go to ure radiators so yesterday I took the bike up an down the road for the first time and about 3 minutes into the ride coolent started spraying from the cap on top of the radiator so I immediately shut the bike down and pushed it home and put it in the shop for the night then when I went to check it out today and I pulled the cap off and there was still pressure built up it also seemed to be leaking from the bottom of the crank case had anyone had this issue maybe it's clogged up somewhere I'm at a loss of what's happening here any advice would be greatly appreciated

Also when I start the bike and run it for about 10 seconds I can spit on the pipe. And it sizzles right off not sure if the 4 strokes generally get hot that fast or what thanks guys
