Changed the belt and swapped the rollers for Dr Pulley sliders (bike at 21,000 miles and I think the original belt) used one of the ones in someones post not OE BMW and it has no arrows for mounting, not the Mitsobishi either. Since It had no arrows I installed the belt so the lettering could be read as it went in it's normal direction, all felt good on the test drive, has anyone else ran into this problem? I'll have more information on the belt when I get to work, my phone doesn't handle searches well past 4 weeks and I purchased this 2 months ago while on break so I'll need my computer at work to search the part and supplier.
