I am trying to understand a couple of probs with my newly rebuilt T500: it was redone last July (pistons, crank, gearbox + modifs) and, as I could nor ride at that time, parked (with no gas) and on a battery tender... last weekend I went through it and found some traces of water in the left spark plug (condensation?)... engine starts ok, idle but does not go other 5000rpm and smokes a lot... I will change the gearbox oil, open the bolts to the pre-compression/crank chambers. But whats next?? It gives me the feeling of a blocked/seized choke plunger, is this possible?
I changed the petcock for a "manual" one cause I am always afraid of the diaphragm ones...now it leaks outside for real

Some more work!
What kind of coils couls I put there? my sparkplug wires are brittle and hard as stone!
Thank you
Philippe
