??WTF is up With THIS.??

[JohnnyP]

I just bought a 1980 suzuki gs750e for $200. it only has a couple problem, so it was a steal. The guy I bought it from had just cleaned the carbs Before i bought it. One problem that i was not able to figure out how to fix was a starting "issue". When I start it it will die about ten second later unless I hold on the throttle alittle (If i let go it will turn off 10 sec. later). If I try to pull on the throttle more than 50% it stumble and eventually shuts off unless it let off the throttle. It idles at 1000 rpm and the most i can get it up to is 2800 rpm at as much throttle that i can give it. What could be the problem?and how to fix it?

Try the choke Johnny.

clean the carbs yourself. you dont know how good of a job the guy before you did them. seems like some jets are clogged up.

Could be fuel flow issues with either the petcock or a kinked fuel line.

Take apart the carbs and clean all the jets. You dont know how he cleaned them. Some people's version of cleaning is just spraying carb cleaner in the bowls.

You've got a case of the "I-just-bought-a-used-bike,-so-how-do-I-get-it-road-worthy?" syndrome. Probably the most common topic in the Tech section of this forum.
Answer: Verify everything yourself.
The problems you're describing are typical of a bike that's been sitting for a while.
I (and others) have posted a laundry list of items to check/verify in order to avoid hours (and hours and hours) of frustrating guessing games and wasted time/money.
Do a search, follow the advice, and you'll be riding within a week or two (depending on how much time you can devote).

My advice? Start at the fuel pump and work towards the fire in order: Gas tank vent #1, petcock #2, fuel line #3, float heights #4...etc until you get to the combustion chamber.

Check the air filter and exhaust for blockages.
