I have a RevTech 110 Evo style engine. It is in the break in period and has run fine for about 300 miles. The last 2 times I've used it, after about a half hour one cylinder cuts out. On my last ride I had to limp home about 5 miles on 1 cylinder. After the bike sets for about twenty minutes, both cylinders run fine. I changed the plugs, and wires, and it still happens. If anybody has any insight into what to look for, it is greatly appreciated!
Thanks for any help.
