New guy having some issues

[Guest]

Hey everyone, I'm new to the forum and have been searching and reading a lot on here. I own a 83 gs450 suzukimatic. Got it cheap as a project and have been working on it. When I got it the guy said it ran good last summer. He left the gas set to prime and the tank of gas that was in it ended up mixed with the oil. It got a new oil filter and oil put in it. He said the carbs had been cleaned but who knows how true that is. I pulled them off and opened them up and they were clean. I do plan on doing a dip just to be safe here sooner than later. Long story short the issue I'm have currently is that I started the bike up a couple days ago. It fired right up without issue every time I started it before I took it for a ride. I ran it down the street real quick for the first time and about a mile down the rd it was bogging some so I slowed to take a u turn and head back home and it died. I tried restarting it and it would turn over but not fire up. The battery died and I ended up pushing it home. When I try to start it it will turn over but not start. I pulled my spark plugs and set them on the engine and made sure they had a spark. Both were good. To me it seems like maybe it's not getting gas but I'm not sure to be honest. When I pulled the carbs off again there was some gas sitting on the boots between the carb and engine. When I pull the spark plugs they are dry. Any ideas as to what to look at or what route to take from here is appreciated. I'm no motorcycle mechanic but have no issue trying to do things on my own Sorry this was a long post I was just trying to give everyone so easy insight to what's was happening. Thanks in advance

First thing you should have done was open the bowl drains a little to see if there was any fuel getting to them. If yes, then the next thing is even though they "LOOK" clean doesnt mean diddly squat. They have sat and they have had fuel coagulating in the jets and plugging up all the passages as it turned to varnish.

They need fully torn down and dipped..jets dipped and all the holes poked clean with a fine wire. And pay attention to the pilot jets as there is usually a small hole in the tip as well as the ones on the side. Once they are rebuilt ( with all new orings and pilot jet plugs...if it has pilot jet plugs..) bench sync them and she should run and stay running. In the interu, while carbs are soaking, check valve clearances etc etc. as per the manual.

Maybe get with this guy and see if he can help with the service. He says he has a factory service manual he got with his bike. Some cold ones and some brats on the grill may be a good day if hes willing to come up north. Flushings only an hr and change from The D. I was at I75 and Nine mile in hazel park for 28 years and am from a little town up north called AuGres.

Here your basic CV carb cleaning turtorial. And use new rubber plugs over the pilot jets and just be sure its correct. Leaky plugs = runs rich and it tricks you into thin king the jetting is all wrong or something when its just leaky plugs.

Well I sure do appreciate the responses. I just got back from a ride. I took the tank off and went through all the wiring and connections. Pulled the battery out and made sure it wasn't low on fluid. Pulled the carbs again and made sure I had them cleaned good(still going to dip them eventually) put it back together and it fired up right away. Took it out for a bit and it ran great. Only issue now is it has a soft pop(backfire). Thinking it might be running rich. Gonna play with it tomorrow if I get some time. Again I appreciate everyone responding. I'll add a pic of my bike for those interested.
