So I just passsed 100,000 miles on my bike and since then the last 500 have been a nightmare. Lots of minor things, until last Friday. I went to get a new oil pan darian plug, as my old one was weeping. When I got home I threw a drip pan down and grabbed a 17 mm wrench. When i looked down I saw green in the pan not brown. I looked and found a crack in the water pump cove bolt. However that was not the only leak I have one higher up on the left side, I haven't pulled the radiator yet, thats tomorrow, Thoughts. I am due for a timing belt, well past due and need to replace the clutch. Though about takling thst myself. I woud lsame I am competent as a mechanic, do 85% of all the maintence.

This sentence does no compute... 🤔

before pulling the rad I'd look further up:
- overflow line
- rad-cap
- internal bypass line (underneath carbs, behind t/belt cover)
- internal passages + elbows (underneath carbs)

Considering it's a '93 failing w/pump seal might also be possible, but I'd eliminate the simple things first...
