Fellow thumpers PLEASE HELP! I’m at the end of my rope here I do not know what to do and I have already spent a fortune! BIKE WILL NOT START, well almost with a fully charged battery it will start! But will last only two days on the third day the engine seems to seize up! And I can’t even push start it! I have even put it in fourth gear (the highest it has) and when I pop the clutch the rear tire literally drags!

This is what I’ve done to the bike:
New battery!
New alternator
New pulse generator
New Voltage regulator
Decompression solenoid adjustment 4mm at TDC
Starter motor was inspected I was told it is still good

Lights are bright and voltmeter says my battery has 11.5 V (I should be able to push start it right?) it was at 12.5V when I bought it two days ago, I do not hear the decompression solenoid clicking but it was clicking when I installed the new battery it seems that the engine will not turn over. Is my decomp solenoid fried? Will that cause the engine to seize up?

Guys PLEASE HELP my last few posts were COMPLETELY IGNORED come on guys throw me a line here the thumper is my only transportation to work or anywhere!

Put it in neutral and open the screw in slotted cover on the port side of the engine. Remove the sparkplug. Use a 17mm socket to try to turn the engine over.
NOTE, TURN CLOCKWISE as you face the engine.  While it is gtrue that this turns the engine backwards, if you turn counterclockwise, you will unscrew the nut on the end of the crankshaft. All that you are doing is to see if the engine is seized up or will it turn over at all.
In fourth gear the engine should turn over when you pop the clutch.
That makes me worry that it is seized.

second that on the battery charge. To rule out the battery's low voltage all together, try to jump it (another bike, car, riding lawnmower) to see if it least turns over. You can also try to jump (read: bypass) the solenoid with a screw driver to see if it turns over as well. I think Versy has it pinpointed, though.

Have you stood it up straight & checked the oil?

You may well have an issue with the decomp setup. I don't think the starter motor has the balls to turn the engine over with the decomp closed. If your battery charge is low, you probably don't have enough juice to operate the decomp. After fully charging your battery you say it starts, yes? When the bike is running you should get a reading across the battery terminal of about 14.8v, anything lower than 13v is not enough.
I had this problem myself recently. I found the problem to be at the white connector block under the pillion seat. Check the red wires that come out of the rectifier/regulator, one of mine was badly corroded. I just bypassed the connector block and spliced the wires together. Every think is cool now.

The decomp only fires long enough for 1 rev.
If you think it's the decomp, you could back the bike up in gear till you feel the compression stroke then hit the starter.
