Hello Motortalker, after my first topic was accepted so well and I was also helped I would like to turn to you again and hope again that you can help me. Now on the actual topic….. I got the above mentioned motorcycle this year with 2 years Tüv and was overtaken or service was made, because I only started to ride motorcycle again (2 years break) I of course always rode gently, but I noticed after a short time, 1. if I on the I found a filter (dry) on the left side, the connections (diameter) are different large ??? 3. Today I removed the battery, get me a gel battery, I noticed the 2 hoses (open, a light and a black) are tank ventilation and ??? and then still a black hose that goes down from the tank , along the engine to the rear , I pulled it carefully and there was no resistance to feel and see there also an open hose (low pressure hose, overflow , ) ?????? I hope you can help me further , could not look now even today because it became dark and I lacked the time / family . LG meinerstermondeo PS .
