When my suzuki gsx 750f gets hot from riding it and i shut it off it wont start back up even if I put the choke on I have had problems in the past with my gas tank not letting air for the gas to flow but then it would cut out like it wasnt on all cylinders or running out of gas. My valves are right on and so is my timing. Could it be my coils or plug wires? It does have 25000 miles on it. Could it be jetting.

I have a 92 Kat 750 motor... don't think it's a kat-specific issue. More likely, it's a fuel or electrical problem.
Questions:
When you say it doesn't start, you're turning it over and over, but it doesn't run?
How long after letting it sit does it finally start back up? Does it ever??
You might want to do new plug wires just for good practice, but if you have had this problem in the past with fuel flow, chances are really good you still have it.
Try this: with the bike still hot, turn the petcock to prime for a bit (30 seconds, say). Turn it to On, and THEN try to start it.
If it starts - check vent tubes and petcock, like Steve said... it's a fueling issue."Men will get no more out of life than they put into it."

Thats what i did to run down my fuel issues, turned out it was the petcock was all crudded up and wasnt flowing gas on the 'ON' or 'RES' positions.

He didn't say it won't turn over -- he said it wouldn't start (catch).
That causes me to believe it's a jetting issue with the idle circuit or valves way out of adjustment or incorrect start procedure...
(A) Too Rich. When the bike is "cold", the fuel doesn't evaporate/vaporize as well, and the mix is right; as it heats up, the mix gets too rich to support starting.
(B) Valve growth due to heat and really bad valve adjustment...
(C) User trying to use the choke even for a hot start.
QUESTION: How long does it need to cool down to start again?

it could be my jets I pulled the aftermarket pipes off and put the stock ones on. It turns over fine but wont fire up. I havent waited for it to cool down to start it back up or see if it will. I know when I bought it it had aftermarket cams, filter and supposed jetting too. Ill mess around with it. Which is the vent tube?I put new Plugs.MY timing and valves are right on. Its weird itll start right up when its cold.Last edited by Nick_08; 04-09-2008, 09:56 AM.
