Bike Model = : GV 125 carb 2000
hi everyone, i have come into possession of a 2000 gv125. i am putting it all back together and im in need of some advice. it was in pieces when i got it.
im having issues with it running and i think most of it is stemming from vacuum lines not being in the right place causing the carbs to become starved of fuel.
would someone please show me pictures of where each hose goes. what i know, pet cock to pump, pump to carb. vacuum from pump to front inlet manifold.
what am i missing? where do hose go to from the left side of the air chamber?
any and all help is greatly appreciated

GT uses more vacuum hoses due to it having a vacuum petcock,Ā but GV has a manual petcock,Ā only worry aboutĀ Front & Rear engines sending air to the fuel pump. That’s all you need to worry about.
Now,Ā the other pipes like EGR (if present on the bike,) throw them away, the bike wont miss it , infact it will be glad as those things are parasitic (robs vacuum energy)Ā and blockĀ the metal tiny pipes at the engine side and then block the airbox’s extra ports.
(I would doubt it , if it is a genuine 2000 engineĀ it wont have egr ports , thats something added to later 2005+ engines to meat the silly Euro3 laws)
(UK for now doesn’t care so to speak as MOT testers don’t check emissions on carb 125 bikes.Ā Ā Just exhaust loudness that’s all.)More on that here:

For fuel (liquids) , here is a specific tutorial , follow it exactly.

The Carb Float BOWLS = Have extra hoses on them that are basically overflow & drain ==== guide them down towards the road.Ā (if you have V1 carbs)
If you have v2 carbs their overfow & drain pipes will be both on top of carb and bottom of carb ==> guide them down to the road.
If still stuck , post some pictures so we can where you get stuck.
Good luck!
