Help KDX220 Coolant Leak After Top End

[nls2299]

Did my first top end ever. Followed manual to a T.
Hadn't got to installing pipe yet.
Came out and noticed coolant on floor.
Traced back to dripping from exhaust opening.
Quarter size drop on floor after 1 week.
Loosened and re-tightened nuts on head back to 18 ft-lb per manual.
Now waiting to see if that fixed it.
Anyone else ever had this issue???
Thanks guys.

I assume you used new gaskets?. If it’s all properly torqued, it should be good. Were the gaskets you took off okay?

All new Cometic gasket kit. When I first installed I did not check torque spec. Week went by and just noticed a small spot. Went out this morning, loosened and then re-torqued all to exact spec. Waiting to see if problem is resolved.

You’ll probably be good to go. You should probably check your tranny fluid if you haven’t already.
