Hello, sorry to play out the classic forum trope, but I am new to this site and i have a very specific problem. I have been working to make an 82 GS450T I got for free road worthy. After cleaning the carbs and I attempted to get the bike started. Here's the problem,
The bike will only turn over with starting fluid. The petcock is somewhat leaky, and I plan to put some gasket maker on it to seal it tomorrow. The carbs are getting gas (i checked the drains at the bottom) and the vacuum lines appear to be in good order, no visible cracks. It has the mikuni BS 34 SS Carbs with 22.5 idle jet and 130 main jet. This is to accommodate the pod filters and drag pipes that it has (someone on reddit had a similar setup and claimed to have success with this jetting). Im guessing that it could have something to do with vacuum although I don't know what, because like i said the lines appear to be in working order. Once i started it with fluid with my thumb over the line that would have led to the petcock and felt light pressure every time one of the cylinders fired. Its my first time rebuilding carbs so there is a real chance i messed something up. For instance, I realized that i didn't connect the vacuum lines between carbs, had the mixture screws way too far out, idle adjust screw too haven't synced or balanced them either (I only realized one had to do that after troubleshooting earlier today).
I am stumped. Happy to post pictures of the bike/ manual that ya'll think would be relevant. If you have any knowledge on carb adjustments/ setup after a rebuild or know any threads that would be helpful I would love some assistance.
Also, unrelated, I was looking for a PDF of the manual for my bike and found Basecliffs website (I Think) but it was archived and i couldn't get anything to download. So I tracked down a GS450 Manual and made a PDF copy of it. If ya'll know a thread that these things go in I'd love to post it because Im sure someone could use it as much as I have. Thanks for reading! Much appreciated!
