I purchased a P/P 1260 2019 in april and it was popping/backfiring so i thought it needed re-mapping to solve the air/fuel intake. little did i know that there must have been a hole on the rear exhaust at the header pipe and the lambada sensor was picking up the difference. luckily the exhaust blew all the way around the pipe about 5mm from the weld on the manifold. i renewed the header pipe and the problem was solved,the bike is running much better and no issues with popping/backfiring. hope this does not happen to any of you guys/girls because it was a pain getting access to the 3 nuts for the manifold. i could not believe how thin the metal thickness is in that area,i just hope the front header pipe is thicker. ps, the weld at the manifold looked good quality ,so that did not cause the defect. happy new year to all.
