Mantis Manometer

Recommended Posts

I just balanced the throttle bypass screws on my M635 with this tool - it really does live up to the hype and has noticeably improved the smoothness of the M88 both at idle (obviously) and as the revs rise.  It's made for the S38, but the bypass arrangement is exactly the same as you'd expect. 


Will post this on both the E28 and E34 technical forums 'cos it's ace!
