suzuki df50 will not rev/keeps stalling

[andyviper]

HELP!
Suzuki df50, 2003 efi, 20 hrs run, only bought this week. Ran fine at dealers, is now running really rough, misfiring, revs will not increase. The only work i`ve done is to shorten the fuel line slightly.Checked both fuel filters, cleaned and drained. I`m thinking maybe an airlock somewhere in the fuel injection system? or maybe water somewhere? or maybe spark plugs. It is under warranty but the dealer is 300 miles away and i want to fix this quickly.

Re: suzuki df50 will not rev/keeps stalling

i am no mechanic, but i have had my share of problems like this... the one thing i've found that worked was to drain the fuel, put in a little gas treatment that disperses water, slowly crank it a few times without starting it, put in fresh gas, say a quick prayer and then try starting again.... it has worked the last two times i had a problem.

since it is still under warr. sadly, your best option might be to drive the 300 miles

good luck!

Did it run OK before doing this?
