Hey guys I'm having a little bit of trouble with this. I got this 02 f4i off of a friend for 200 he said it was the water pump. Put one on realized afterwords that the water pump is not the issue. Run a compression test on the heads got good results. Took water pump back off and could feel the coolant run over my finger as the coolant was being poured through the radiator. Is there somewhere else that could possibly allow coolant to pour in like maybe the oil cooler or some kinda of "plug". I'm not familiar at all with liquid cooled bikes. This is my first, normally I ride my katana that I built. But I'm anxious to see how much faster fuel injection is. So please help.

 

If the water pump is off and you're adding coolant, it will definitely come out.

What's the issue with the bike?

 

It has coolant in the oil. Replced water pump bcuz that's what I was told the problem was. Turns out that with the water pump out I can see it pouring into the crank case. Not through the water pump. Been doing some reading and it says its pretty common for the oil cooler seals to go out so ill try that before I do anything else

 

F3, but similar thing going on....
