i need help setting my needle jet for 2100 ft. elevation and i have water leaking out of a hole thats under the water pump in the case cant tell if its threaded for a plug ? this is my first zilla

 

i cant help you on your elev., but on your waterpump the nut underneath it is to drain the radaitor. if it is leaking from there, you can just replace bolt which is metric or use some plummers tape or some sealent. any other question let me now. i just redone a 85 lt250r, from the ground up.

 

Thats the weep hole that lets you Know the water pump seal is bad.
