I also have a ultima 127, I have tried retarding the timing and running 60 wieght oil and it is still running hot. The oil brought it down to about 230 from 250. Can anyone help. The motor was just installed in a custom, I have only put about 45 mi on it and after a half hour I have to shut it down and let it cool off.

I just got mine going and it seems to run hot. It vibrates alot. Ive only got 40 miles on it. Do these motors smooth out after break-in? If so when..

I got under 100 miles before melting the back of the front piston.  Replaced them with ceramic and added a 14 fin oil cooler, richened it up and got 30 mile s before burning it down again.  This is a hand built engine not a boxed unit. It is back at the builder who is scratching his head.  We will make sure the rear cylinder is not starving the front for fuel and will increase oil pressure. don't know if we have solved problem yet.
