Well, here is the deal. I can't get the stupid thing to run with the high flow filter no matter how hard I try. I have a full range of jets from 56 - 88 and none of them seem to work! On the stand, the 74 jet with the 15mm bing SCREAMS... like 12,000 rpms. Winds right up, sounds great, looks great, I figure here we go! I sit on it, and the ped won't break 15mph and takes 3 weeks to get there. I have tried a 70, 72, and 76 and 78. None of them run as well on the stand, and even worse with a rider. What gives? I should add that the 70 jet with the stock airbox was a tad lean in the colder weather, but the 72 with the stock box was right on time and got me running at 28-30 mph.
Any ideas on why the high flow air filter won't work or anyone had this problem before? I really think the stock airbox is limiting my potential.
