I had a custom map done for the busa when it only had the R-77 slipons. Now I am headed back to the dyno with the full R-77 4-2-1 system. Is it ok to ride it to the shop (about an hour ride on the interstate) with the current map for the slipons or do I need to get something close to right for a full exhaust even for the ride to the dyno?
