What weight of oil do y all use I bought this bike the previous owner used only 20 50 I went back to 10w40. Now I have a oil leak from my exhaust I used high temp gasket maker to try and seal it there was no gasket in there. I was just wondering if I should go back to the heavier oil would that make a difference bike is old with 14000 miles on it?

Pumping out around the exhaust where it bolts to the cylinder head no gasket between exhaust and cylinder head.

I run 20w50,especially when I lived in Texas.General consensus around here is 15w40 rotella(diesel style oil).
DO NOT!!!!Run car oil.Too many friction additives.They will make your clutch slip.

Is it safe to run with head plug leak if I bring extra quart of oil  until I can fix ? Will heavy oil leak less?

I ride 65 miles to work one way. Should I go with heavier oil and keep adding some when it gets low. Will the heavier oil leak less than the lighter oil?

I'm going to fix it but the plug will not be in for a few days.  I still will have to get to work.  Any suggestions?

We had one member who thoroughly cleaned the area to get all the oil off the parts, and then applied high temperature silicone to the bottom of the plug, and had good results on a temporary basis.  We have not had an update on how long it worked.....

There is a local forum member here with a plug leak that I might try to talk into trying this approach......so we can see it it works.

A tiny bit less....but hot oil of any weight will still leak.
