Not that much in 20 years of biking... i usually end up talking myself into trouble at roadside
twice for wheeling, and given usual sarky lecture at roadside 'so how many wheels has your bike got', 'err two officer', 'and how many were you riding on', 'err one officer' lol
overtook unmarked police car at 90 racing a R6, we both got pulled
got pulled on R1 by some copper who was on way to work, the unmarked (his home car) kept coming up behind me flashing lights on main road through devon.. I thought it was road rage and kept speeding up to get away from the fool. In the end I did a couple of miles at about 150 only to then have him next to me signaling for me to pull over. He then gave me some half arsed lecture about 'you were doing over 110', if only he knew

...still he couldn't do nothing as he had no equip in car.
got cut up by car on entry to dual carriage way and i was so near death and mad I wound on bike to silly speeds, only to then have the fool who cut me up come up behind and turn on flashing blue lights... they pulled beside me and passenger held cap to window and mouthed 'sloooww down' phewwww, guess he felt guilty at nearly killing me
got followed into work and issued ticked for crossing pavement on hayabusa, I got cocky when they lectured me in car park explaining 'I bet you wish you caught me at 200 down local dual carriage way other night', didn't do down to well...
pulled a couple of times for noisy pipes, and also once for 'indicators to close together', the fool got out his tape measure and said they were 10cm to close together. got fined £400!!!!!!!!!!!!!
