coming from car servicing where you only do the filter up hand tight, is it the same for a bike? I noticed my manual said not to but without a centre stand it is almost impossible to get my filter wrench in there. I rode it for 100km on sunday no probs, but after a ride yesterday noticed the distinct smell of oil burning on the exhaust. I did spill oil on the exhaust and enginge block when taking the old filter off and wiped most away (didn't degrease) so am wondering for safety sake should I try and get my filter wrench in there and tighten it more? Next time I will buy a k&n filter over the genuine kwaka one as it has a 17mm nut welded to it and would make life much easier.
