Hello all new hear and in need of a little help my 97 xj600n has just started pushing out what i can only describe as water oil mix from the breather pipe also oil filler cap has the same white gunge on it bike is running fine any body any ideas ?

head gasket gone

cry, take it to a garage and sign over a substantial cheque

or...

buy a haynes manual and do it yerself. make sure you have a knowledgeable mate called dave (can be called other things, but dave seems to work best) within easy reach

first time tho, or mechanically unsure, pay someone.

problem all sorted now turns out was jusrt a simple airbox problem and alot of condensation local yamaha dealer first class for help thanks all
