Tap next larger size. I don't like helicoils but I suspect you could get a timesert insert in it if you wanted to.

They make two kinds of inserts that I know of..the heli coil and timesert (better). Or you can go the next larger size, although the jug has to be drilled out at the same time. Another option is a aluminum stick that can be heated and fill the hole, drill and retap. This stick melts at 700 deg F. I know MAP gas will get it hot enough and I think propane will also. I replace just about all the cheap Chinese C*AP with good hardware on all my builds..and haven't had a problem. I use red locktite on the cylinder studs.
Time for A up date.1/4 in threaded rod and A 1/4 in tap
no drilling needed. It worked fine. I ran over to lowes 7pm
after reading G-superior thread. No need to any drilling the
tap worked perfect just the way it is.I have A sears torque
wrench I torqued them to ten foot pounds.The inffo that
came with the motor said to totque them to nine foot
pounds put my wernch only goes as low ten foot pounds I
figured whats one foot pound among frinds.

12 inch pounds
.... All kidding aside I use a inch pound torque wrench on these aluminum HT'sIn early 60`s I raced a Jawa in those days we ran 30w oil at 20 to one.
I would put new rings in about mid season and when I would have cylinder 0ff
and check it out it was never as slippery or with as mutch oil on
the fly wheels as I found on my MB. After 4 gallons im going to take the head of and check it out. Ill keep you all posted on what I got.
