I can re-haul intakes for all 1100 an 1150 BMW boxer motorcycles. After using the bike for a few years, the spindle and the intake bushings get worn, resulting in the spindle play, resulting in that annoing rattle and may leading to bike surging. I can fix your intake if you send it over or I cand send you a complete rebuild kit and do the work yourself. A kit contains: a new splindle(shaft); necessary bushings; set of complete o-rings; the small screws that hold the plate to the shaft. Having the intake full repaired is just like having a new one, but at a fraction of a cost. Just contact me specifying what bike model do you have and the manufacture year. The price is 60$ + shipping. Dan.
