newby On the verge but 1997 1500SE

New to the forum and the Goldwing but not cycles or mechanics/electronics.

Looking into buying a 97 1500SE well maintained and with records. 80k on the odometer.

Owner states " runs great on a full to half tank of gas but when lower than a half the engine starts to run rough".

Need a little insight...... something minor or Time to run away. Take off on a cross country or fix before leaving?

Thanks for your time

It sounds like a fuel delivery problem. There are classic problems with the fuel pumps and vacuum fuel valves. There are rebuild kits for the vacuum fuel valves…. ebay under 'rebuild fuel pumps' will bring up the rebuild kits.
There used to be a rebuild kit for fuel pumps also but they seem to have disappeared in the last year or so.
Wouldn't be a bad idea to replace the fuel filter…. just because it's new to you and you don't know when it was done last.

Thanks for the input..

In the past I've had bikes that had the same type of symptoms and it turned out to be a plugged vent in the gas cap. Possible?

From what I can gather this problem shows up at about the same tank level no matter the outside temperature, how long the drive, road condition, back road or freeway.

Again thanks for your time.

Fuel caps are cheap, replacing it would be a good place to start.

The clue is in the warning ...runs fine to 1/2 tank then poorly....

The GL1500 will gravity feed the carbs with little help from the fuel pump down to this level (1/2 tank)...then the fuel pump needs to help ...the weak pump syndrome is common to the mid-90s bikes ...mine was replaced at 85, 000 miles .a new oem pump will cost near $300 if you install it yourself....

Not adeal breaker ...but a fix may be in order...

Just my opinion..of what it may be.......

Thanks to all for your input and the advise I received on this site is Great...looks like the rig is in need of a new fuel pump.
