Here goes:
I rode it for two weeks and only the second one I had problems.In the first one I guess I rode it through all gears and I revved it through all the scale regularly.I wouldn't say I rode it hard though .I stayed in the 6k area mostly.
If I remember right (most unlikely) the the jetting is stock.(It isn't accesible at the time so I ll get back on that later)
Wire splice(1st and 2nd gear run to 3rd)
The airbox is fitted normally and the filter is a new Daytona one.(I think it doesn't fit perfectly though)
The carbs were cleaned with the proper fluid and procedure and the levels were checked.
The spark plugs are the NGK's (new ones/don't remember the exact type)
I topped the oil tank 10 km before the seizure.There is plenty of oil left although I noticed later that there was some spilled over the general area of the oil tank.(i did not spill any during the topping up).There is a possiblity that some oil was spilled during the transportation from the street to my garage though.
