Just broke it in and ran it at pro series. Easy breakin, The power of this engine is like none other I have run before. I have about 1.5 gallons on the engine so far. Most people say it doesn't open up till about 2 gallons. I am really excited to see how it goes. Only making 6:45-7 on a wide open track, but it is still very rich. I will make a review later once it makes it to 2.5 gallons

Break in was a breeze, leaned it a few hours on HSN and it's rip roaring now, strong and smooth from bottom to top. Highly recommend this engine for Buggy or Truggy. Very impressed with 1.5 gallons on mine. Easy to tune and very consistent. It sounds unique with the pipe, really awesome combo!

Should be real good, as this engine seems to have the same Bore & Stroke/ Port configuration as the Sirio CL7B STI engine.
Star engine (Sirio) made Just Orion Branded & Says it has the CRF Crank, different type of Carb and some timing work done to it.
I use a Sirio CL7B & Dyn 086 Pipe in my MBX6 and love it. So I guess I will be loving this engine too ! LOL.

I don't now if its the best but I'm using a P3 plug without issues. Breakin on this motor was not an issue. I'm waiting for clear weather to complete the final tune.
