Blow-by

[humbucker88]

Do you guys feel any air/slight pressure when the oil filler cap is off and the engine is running? Not sure if being paranoid...

If the bike runs o.k. with no blue smoke it sound to me like you'r being paranoid.
Two pistons are going up as two are coming down but there will be some air movement as the pistons thrash about.

Its never even crossed my mind to run the engine with the cap off.......why do it out of interest?

Similar question to "So why did you shag that ugly fat bird"

Same answer - "I was in desperate need of a look"

It's normal that's why there's a breather on the crankcase
