Sounds like it is leaning out, running out of fuel. That can be the strainer at the gas tank, any fuel filters it has. Disconnect the fuel line from the carb and see how good the flow is to it, and check for water. A new spark plug never hurts.

You need to check and see if you are getting fuel from the tank into your carbs, if you pull the line that feeds the petcock valve off the top gas should come out. If it doesnt there is a clog in your tank. Now pull the line off the bottom of the petcock valve (this feeds your carbs) and make sure you have fuel at all setting of the petcock valve except for off. If you dont then you probably have a bad petcock valve. If you are getting fuel from the petcock vavle into you carbs then there is a problem with your carbs.
If you take the fuel bowl drain screw out of the carb (located on the bottom). Gas should run out of the associated carb, if it doesn't, then you have something stuck in the carb and one carb not working correctly can make the bike not run. If you find this to be the problem get a can of carb cleaner, take the fuel bowl drain screw out and let the gas run out, stick the red spray wand from the can of cleaner into the hole and flush your carbs out really good.
Then give it a try. Make sure that the connection between your carbs and head is tight while you are there. If that does not fix your problem you may ahve to pull the carbs and take a closer look.

Hello, there are several things as likely to cause this problem, either spark or fuel.
The glowplugs are needed to make a Cold engine start. You can take a testlight to the glowplug wire of several cylinders and it should light when the engine is put to the Run position. The glowplugs get their power from a Coldstart Timer and it may have an additional relay.
The Coldstart Timer is the part which clicks and makes the lights dim when it is cycling. It also controls the dash indicator and makes the dash light work when the glowplugs are ready. The timer changes the amount of time it cycles according to outside and engine temperature. If you have noticed the "Ready" light vary its timing, the timer is working.
Say you have no spark at the glowplug wire, work backwards to the Coldstart timer and see if it is getting power. Power in, none out, bad timer. No power in, work backwards for a Relay or fuse.
Now if you have power at the glowplug, remove several and test them with Battery jumper cables. Put the NEG on the base and touch the POS to the stem. You can melt them if you overdo it. The longer it takes for the glowplug to glow, the worse it is. Once you find a good glower all tests are relative to the good one.
Fuel problem. If the glowplugs test out, check the fuel. Long start times can mean the fuel drained back to the tank and has to be pulled all the way up front. You can unscrew your fuel filter and see if it is topped off or empty. Then you need to test the lines from the fuel filter back.
It is also possible an internal Solenoid in the Injector pump is sticking. A light tap before starting can indicate this problem if it starts better after tapping the pump.
Thats about it. I hope you find my Solution useful.

check manifold, coil pack, tune up, injector cleaner too. Had mine 12 yrs now.
