We have used a 35 pilot jet fitted to a EC250 or EC300 when Trail Riding or for Clubman / Sportsman Enduro. It cleans up the power at the bottom end and makes a huge difference to fuel consumption. Most EC models are supplied standard with a 40 pilot.
This air filter cover is a must for washing the inside of the airbox whilst washing the bike. Simply remove the air filter, fit the cover and wash away! This new version fits and seals even better with a stepped lip that prevents it slipping out of place when fitted.
