i recently went to bangalore on my bike completing 650kms under 8 hours.i maintain regular tyre pressures of 30 front and 32 rear...but on long trips i maintain a 35 rear.bike is 1.3 years old with 20k on odo..in bangalore the bike was parked on the open hence subjecting it to cold nights and summer days.it was used for max 4 hours for the whole week.after that i returned to hyderabad under the same time and cruise conditions...after parking my bike in my apartment,heres what i noticed the next day :

1) my bike's oil goes to my airfilter after continuous prolonged journeys of speeds above 115kmph with little or no rest to the bike.from the airfilter the oil leaks to the ground.it has happened before when i went to bangalore and it has happened now too... in fact i was so sure that it would occur again that i cleaned my bike's parking area so i can notice the oil the next day. the last time it happened,my mechanic replaced some rubber component in the right side of the engine.its a small rectangular rubber thing which is lodged inside the right side engine cover.he said that due to continous high speeds and prolonged hours without rest,it has become thin and hence oil has leaked into the airfilter box.on both occasions that is the previous time and now after bangalore tips,that component was changed and leakage stopped instantly ...my issue is does this happen to all 220s ? isnt this a problem if i go for IBA or something like that??


2)when they raised my bike on their platform to change that rubber thing i noticed this on my front tyre...rear is ok...what can be the cause for this?
