If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

Gs250t Vacuum Leak Bike wont catch

Sounds like the charging system isn't working. There are literally thousands of posts here on how to check the system and fix it so please do some research and tests.

It also sounds like you have air leakage issues; the airbox must be 100% sealed to the carbs or the mixture will be off and the bike won't run right. Please don't monkey around with tape or the like in an attempt to seal this system. Get the proper parts. New boots that attach to the head and new boots for the airbox too that attach to the back side of the carbs is money well spent.

I'd buy those and install them, and go through the carbs properly, updating the O-rings to assure good sealing. You can do the job right one time or shortcut and have to redo it all again later.
 
Hi Nessism

Thanks for your insight, I recharged the battery and discharged about 3-4 times and on the 4th go the engine started up again. I tested for vacuum leaks using carb spray and also using starter fluid and saw no change in the rpm of the engine, I presume there is no airleak. I tested the battery at idling speeds and saw that the voltage was 15.4 at 1100 rpm... which seems very high, especially for idling. I think the voltage rectifier is gone. Original rectifiers are seemingly very expensive, I am hoping to wire up a more universal connector to use with newer rectifiers. I will do further research, but if anyone has a diagram or a quick summary of the wiring as a guide, it would be much appreciated.

Many Thanks.

Jake.
 
Also, sorry to bother you Nessism, I was uncertain about the seal between the airbox and the carbs, the boots were in a good position. I do not know where I can pick up a "new" airbox to fit more snugly, If I could be put in the right direction that would be great.

Thanks,

Jake.
 
The culprit is either bad fuel or ignition problems, judging by what you have written so far.
Water in the kill switch is pretty bad, and will make your bike a no start even with starting fluid. It sounds like you got a lemon.
 
Hi fbody_mike

It seems that I will indeed have to upgrade regulator. Thank you for linking your thread, it is very useful.

Many Thanks,

Jake.
