Gs250t Vacuum Leak Bike wont catch

[Nessism]

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.

Check out the link above. I recently upgraded the regulator on my gs250t. Sounds like you need to do the same.

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.
