RE: RBMods SureFire 32R break-in
If you are running the exhaust deflector, you may have way more fuel pressure than normal, thus more fuel forced through the jets at a lower setting. Little restrictions in the exhaust make a huge difference in fuel pressure. BB
Edited to add that when I switched from the Hpi pipe to the 086 or 053, it was really rich, barely able to pull itself rich, over the tuned setting on the Hpi pipe. Mine's not modded, but I would imagine the carbs are still the same.....
