Well, we had some rough weeks over here in Pays-Bas. Due to my ignorance using 10-year old yellow Aspen 4, the 4 carbs clogged up totally (on the left 'Aspen', on the right fresh '98).
We renovated the carbs completely; removed all the parts and frame, cleaned them and ordered some spare parts. With some help of our local hero 'Danny's Motorservice' we put everything together and finally today: white smoke! (not literally.........)
This weekend we will post a video with the Yamaha back on the road, exact a year after starting the renovation.
