Brown Gook and why?

[OB_KawAbuser]

Some of us have had problems with engine cut out and Suzuki answered our trouble with Service Bulletins 108 and 109 to remedy this.

First off I thank you Suzuki and the members of this board for supporting a complaint that has been rendered an effective solution.

Ok where does the bown stuff come from?

Why does it not affect all bikes (regional gas supply)?

Which group of bikes (serial #) most affected?

How many miles before the symtoms are noticed?

Fuel additive from fuel mfg.?

Tank anti corrosion coating from Suzuki?

Why is there a coating on the throttle bodies butterflys?

Why is there a coating on the intake valves that looks like burnt oil?
