Hi all, thanks in advance for reading the post. I have an 05 1300R with 15k mi. It was mostly stock but was drilled by a previous owner. I de smogged and decap'd it and put in a K&N filter then added the FP 215 main, 58 slow and put the clip on the 3rd groove from the blunt end. I don't remember where the AF ended but it ran great. Last weekend I swapped the stock (drilled) exhaust with a set of Cobra Dragsters with baffles in place. I put a 220 main in and moved the clip the the 4th groove. I set the AF at 2 turns and she fired right up. It runs better than ever and I made no other adjustments. But now I notice after I shut it off there is a strong odor of gas fumes in the garage a few minutes later. I never had that before. I've pulled and replaced the tank twice to check all the vacuum hoses, which are only a year old, and everything is snug. I see no fuel in or around the airbox and no leaks around the petcock. Any advice on what else I could check would be greatly appreciated. Thank you.
