Was just on a ride with my Windy Head (this one is old picture). It ran ok even though one bulp out of four is now in place with plastic pudding and exhaustion recovery stuff. Filled the whole place with that stuff so only the white part of the bulp sticks out. So far it has hold about 400km. Hoping it will last the whole summer. Carborator I have tuned with eyesight agains light and and air/gasolin screws are in a continuous change, trying what would be the right position for them (can't now check from that one bulp is the mixture right). Lifted the carburator needels to highest and opened the air screws 4,5 full turns.
