I like to use a pipe intended for topend during breakin, and up to a gallon on new engines, this will almost always give you very rich settings on the needles and keep from bogging if people tend to go a little far during this process, i have seen the GO engines have a lean bog if they where set for a race tune to earley, they need at least 1/2 to 3/4 gallons on them before going from concervitive to full race tune.
When you are going to start leaning the needles, be sure the HSN is flush, and stsrt going in on the LSN first, the GO engine has the HS set very close to what it should be at race tune, so i like to turn the LS in and fine tune with the HS, after full breakin the HS may go in 1 to 3 hours max, but the LSN may be in 2 to 5, it all depends on plug,pipe and air. If your breaking in a new engine with a bottom to mid pipe, a bog may show up faster when leaning because the fuel is not scaveging back to the engine like it does with a topend pipe, this is also why bottom end pipes get less runtime, it needs a fat needle setting to keep fresh fuel flowing, since it doesn't scavenge like a top end pipe.
Just give the engine some time to seat, and if you can get a hold of the new GO 0801, this pipe offers better bottom and top than the 2047, and has just as much top but more bottom than the 086, you will like this pipe alot, and the runtime is very nice with this set up. Good luck
