Hello fellow riders, I just got this “project” bike from a guy on the internet. Title says United Motors and branding on the bike as well, however from searching the internet it’s a rebranded GV650 for US market. I have rebuilt the almost all brake/electrical/fuel components myself and finally am trying to attach the air box/fuel tank + fuel/vacuum hoses . These were already disconnected or missing when I took delivery of the bike. Now then on to the problem I am having, there are no direct diagrams for the all the parts I have. I’ve looked into so many parts catalogs/service manuals, and none of them have them listed. I’ve stumbled across a post about the AIS delete and fuel/vacuum line routing for 125/250 but not for my motorcycle, hopefully the pictures can explain along with this post.

So I haven’t had much luck with finding answers so I will just wing it from what I do understand about carburetors and update with photos on imgur. Today’s update has now been added.

Hey,
You can always click “Add Media” on this reply box , so you can paste images directly as you type your replies.
Imgur is a handy backup for sure.
So i read through both links now, first off , nice progress!
The AIS = general consensus is to ditch it , especially if some of us have enriched the carbs or the exhaust has changed , we usually bin the devices associated.
The engine “pipes” , not many in the UK especially 125/250s remove it, they just get a short rubber hose and a bung/roundblock & clamp to the end of metal pipe. basically its bypassed at engine level
Ofcourse ditching the engine pipes with flat blanks is for the visuals 😉
The airbox either has 1 or 2 air ports under it that lead to the AIS device , that can be blocked up too. Now any vacuum related pipes will simply be used to open the fuel tap & pump mainly.
Least there is less pipping clutter everywhere.
See how you get on next!
