My '02 is acting weird

Hey, Last two days i have been driving and someting strange have occured to me about the behavior of my r1 02. Just sometimes, maybe once in a 10 miles, when I am driving and mostly when i just have or am pulling the trottle, the engine makes something that feels like a misfire. I open the trottle and with a given rpm the engine stops pulling and also seem to block the back wheel a bit. It once happend in a corner and it felt i was breaking out, but i felt the engine holding in. It just takes a split second but its significantly noticable. It happens when I am revving, or when i was just revving. It seem not to happen when I am driving slowly. I hear something like a "burb" when it happens, but the noize is hardly noticable. In the last 50 miles it happend maybe 7 times. The bike has done 18.000 miles and has a Akrapovic slipon,BMC sport filter, PC and a home made ramair mod. The PC has a stock map for the slipon and filter. I hope maybe someone is formiliar with this problem, I didnt check anything out yet. I also hope its not that kind of problem where you have to check every part out. Any help is very welcome !! Thanks, Tom

it sounds like your not getting the fuel to the engine, check your filters or spark plugs

it sounds like your not getting the fuel to the engine, check your filters or spark plugs OK thanks, Ill check the filter and then the spark plugs asap.

if that doesn't help, pay attention to the throttle position and speed it happens. If it around the same, you may need to adjust your fueling in the PC. You may be leaning it out. Also, check the PC accelerator pump settings, especially if it is directly driven by transient operation. That does some weird stuff, but it is designed to help alleviate leaning out during transients. Good luck

Yeah I thought it could be the pc, i had it installed a few months ago and uploaded a stock dynojet map. A few weeks ago when i checked the map; it wasnt installed on het pc, so I uploaded it again. The problem exists probably since then. Im going to take the map out and have it custom dynoed a.s.a.p. thanks for the help! Tom
