EVO cutting out on acceleration
1991 EVO (FXR)
24,000 miles
Andrews EV3 cam
Screamin Eagle adjustable pushrods
Screamin Eagle igintion coil (New)
Screamin Eagle Ignition module (New)
Magnecor Wires (New)
stock ignition
Just installed a thunderslide kit (175 main jet, 42 slow, needle in #7). Been going to/from work which gets the bike up to around 75mph with no problems. Then this weekend I opened it up to 100-ish mph and when I got back to town the thing has started to cut out really bad on acceleration. It cuts out at all speeds (putting around town at 25-35 mph and on the highway at 55-65mph too).
I checked the plugs and they seem to be fine. they look a little "fat" but still have a nice tan going on too.
Any ideas?
Gunk in the carb/jets?
Float situation?
Intake leak?
Could it be a damaged intake/exhaust valve?
Valve springs?
