Bounty Hunter, appreciate if you can provide me some guide to break in the engine and to maintain it.
Well first off I use Odonnel 30% and RB Plugs. I use a #4 which is a Med Hot plug (different plug manufacturers use different scales). I have found this plug to be equivalent to a Mccoy MC59. The Mccoy however does have a wider temp range that it can handle. Anyways I use a #4 for break in, about 4 tanks idle on the starter box. Just leave the factory settings on the low end the same. Always remember to look for lots of smoke from the pipe, and the pipe should be spitting plenty of oil. After 4 tanks ont he box you now move to the track and do another 4 tanks at the same settings. Remeber to not run at any one given RPM for any extended period of time. Just blip the throttle around the track. After you have done that, I then move to a RB #6 (Med Cold) and start the lean in the top end needle. Remember to only lean in an hour to 2 hours at a time. I would get the engine running to about 220 and run your entire gallon through it. Once your gallon is done then I bump it to race temps (260-270). For the price the motor screams. The only drawback is the time it takes to break the sucker in.
