Ok, this has happened about 5 times now and the fix is a relatively simple affair.

Symptoms:

The bike starts but as soon as you try and rev it, it dies.


The reason:
White crystaline deposites blocking the pilot jets

The Fix.
Stip the carbs off the bike, open the float bowls one at a time and unscrew the pilot air jet down the tube next to the main jet. Clear it out with a fine piece of copper wire. Blow out tube.
Repeat with the other side.
clean out the bottom of the float bowls with carb cleaner and reassemble.

I haven't traced the white crystaline substance yet but it keeps coming back from somewhere. Even with fresh petrol.

Cheers,
Carl

Update:
The white solid turned out to be old "varnish" inside the fuel system from the bike sitting in storage with fuel in it. The detergents in the new fuel has been cleaning it off the insides of the carbs and tank.

Hopefully it's now cured.

Cheers, C

Thanks for the info.

Maybe you should consider adding an inline fuel filter.

Maybe something like this - http://www.ebay.com.au/itm/310385327525?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648

Hi Brian, wish it was that easy. The fuel actually dissolves the varnish then it crystallises out if you don't run the bike for a couple of weeks and the carbs dry out. Guess I'll have put a switch into the fuel pump circuit so I can run the carbs dry after riding Cool

cheaper than a switch, and if you have access to a visible fuel line is simply clamp it when running to shut the fuel off, even a sandwich plastic bag clamp works, you know the lock and seal clip type Laughing

Cheapness should be appealing, espec when you only need it when storing
