2003 BMW F650CS (great commuter)

Anyone have any sage advice for total loss of power?

One fuel bowl (of the two carbs) had obviously bad gas (smelled awful) some grit in it, so obviously clogged carbs...easy right?

Right...I have taken the carbs off twice and soaked and cleaned...pretty certain all the jets and passages are very clean at this point - there was no varnish, just particulates in the fuel bowl... Replaced the now fouled and abused plugs - bike starts fine, idles smooth, but NO power!!! seriously, worse than a 25cc scooter. Vacuum leak? I checked the lines etc., but nothing obvious....any suggestions?

Love to hear from everyone - advice or rides!
Viagra will help your "total loss of power", but only if you be a guy.

Your carbs may be a "CV" design (constant velocity), where a thin rubber diaphram is used to lift a slide to let in more air. A vacuum leak will prevent the slide from lifting, meaning no power, but it would idle fine.
