Fuel filter is located near the fuel shutoff valve within three inches. It is inline between the shutoff valve and the fuel pump (towards tank).

The fuel circuit is: Tank/Fuel Pump/Fuel Filter/Fuel Shut-off Valve/Carbs.

You first step is to check for fuel delivery to the filter. Make sure the bike is cool and no iginition sources are nearby. Disconnect the inlet line at the filter and turn key on and crank engine (to trigger fuel pump.) Do not try and start at this time (choke off).

If fuel is adequate to the filter, check the filter by blowing through it, it should easily pass air. Replace filter if questionable.

Next reconnect the fuel lines and remove float bowl drain plugs in the back of the carbs (2 per carb). If with key on and cranking fuel pours out of these ports then you probably have clogged fuel jets. If not then the float bowl needles / pipes could be plugged with varnish from dried fuel. You can try spraying carb cleaner into the fuel inlet to clear the varnish and then retest. Careful not to spray carb cleaner on yourself (wrap straw with a rag).

If you have good fuel flow to the carbs and bowls you probably have varnish plugging the jets. You should remove the carbs and clean them thoroughly.

Hope this helps,

Kal

this happens after they sit a while, get her started, get her rolling, put her in second gear, hold the clutch in, get her up to 20 miles an hour, hold a little throttle on and slam on the rear brake, this usually will free up the stuck friction plates. If not try it a couple of times, it has always worked for me, also if that does not work for you you have to take the side cover off of the engine (clutch side) and using a flat headed screwdriver, and a zip tie to hold the clutch lever back to the handle bar, place the screwdriver in between the clutch plates and gently pry them apart from each other, on your bike I believe you have 7 friction plates and 6 steel plates. ( if you have to remove the cover go get a gasket first).

The problem is that your idle is adjusted to low just like mine, you need to adjust your idle

Question . when you say the spark plugs fired , do you mean that you took them out to check ?? or do you mean that you heard the engine crank over.Either way if your fuel tap is faulty,you have more than likely dumped a hell of a lot of fuel in your donk.Blow compressed air around spark plug holes to remove grit,remove all the plugs,put them back in their caps and ground them to the engine away from the spark plug holes in the cylinder head,Crank it over for a while,not too long,reinstall plugs and crank it over.It should be a goer.All the best luck liesel...Tabby.
