Ran my first tank of sidewinder 20% with some massive mods run in oil through my new mg66. The engine was tight as hell!!!!!!!!!!!!! I thought I might have blown it up at first. It started, then went straight to shit. So I took it back into the house removed cooling head, everything pretty. I heated it up to 210 with my heat gun again went out there got it going kept it going through it's first tank. Do these ever run out of fuel? One thing I noticed was how it ran with the 2072 pipe that go-tec makes. Runs a lot cooler [pipe not as hot] then the dynamite 086 that I have been using. The engine is staying at 230ish range. I turned the low speed needle in 1/2 turn. I did everything as stated in the instruction sheet that came with the engine. And also followed the instructions on the run in oil. Did everybody's engines come this tight? Does any body here in the states want to buy a new GXR-5port? 200.00 shipped lower 48 only. After hearing the mg purr I won't need the 5 port! Mark,Grizz if you read this and see I am doing some thing wrong let me know. Thank you.
