Accelerator pump leaking – 2007 GT125R

[jmull1]

Bike Model = : 2007 GT125R

I’m trying to find the internals to the accelerator pump please if possible? I have fuel leaking out between the plunger and the hex bolt. Is there also a blown up diagram of the carbs? Thanks!

Unscrew it, and place a fuel safe o-ring from a local shop like halfords or something, there is an O-ring usually as it is just a plunger that only squirts a bit more fuel on 0-1/4 throttle twists.   Not critical as GV Aquilas or older GT Nakeds never had it ,  it’s a GTR thing.

And sure here is the diagram  (Press and hold to save image to phone or PC) – You won’t always see the plunger as the diagrams still used the 1st generation carb floats

Thank you kindly. I’ll give it a go!

I was going to say it is the gold nut that usually has the O-RING  , the silver plunger has a spring to it.

So focus on the gold nut to seal,   unless its leaking through the actual silver rod  (would be odd if it did)

I have the same problem, I read something about check balls and the plunger failing so im just going to replace the plunger as it is leaking up the middle not the actual O ring on the brass hex thay goes into the carb itself.

Could use a spare nut from a DIY store that fits (i forgot the size) ,  as a temp measure to get back on the road,  until you both find ways to fix the actual issues or patiently wait for a replacement used float to show up on fleebay
