hi just wanted to warn anyone with an ar that the oil pump bleed bolt seems to be made of cheese! i sheared mine today, and leisure trail quoted £106 for a new pump! i took mine to a local machine shop who got it out. replaced it with a high tensile allen bolt and all for a tenner!! i have also had to replace my 2 stroke oils sender ( essentially a rubber bung and 2 wire...) which was £40 from leisure trail. the ar seems to be the most expensive trail bike in the world!!
