Anyway a >260kmh fine for the bar room wall with a picture of your 12r framed together will make you smile long after the sting of paying for the fine is gone
Down here in OZ you would get a one way trip to jail for "hooning" at that speed anything 40k over the limit is frowned upon but the plus side the police won't chase you over 160kmh "too dangerous" they just sit and wait at your home for you [IMG class=inlineimg]/images/KawasakiWorld_2016/smilies/tango_face_sad.png[/IMG]


get your 12 sorted out and running correctly you will love her but be warned she has an evil side Craig
Thank you for the orientation

320€ fee and no jail I’m guessing it’s fine by me

I’ll get back @ you tomorrow. Mechanic is top notch but visit him yesterday and it was not very happy this time...could mean bad news. Rode the bike though 3 days ago and seemed fine with no stopping or traffic just 2 km to the shop. Let’s see thank you

Result @ bike shop was a leak on the passage of the water that went to the head junction. That lead to the overheating and overpressure of the motor. A costy repair.
