  • DT200 surging

    I have an 1989 Suzuki DT200 carbs were just done, new water seperator and fuel lines.

    Last time out ran great. Yesterday had a no spark condition, was the kill switch. I disconnected that and it now it fires, after hard cranking for 1-3 mins. Once warm, it will Surge stay at 2200 then and fall to idle of 950. The interval at surge and fall is a min or two each.

    Sounds like the IAC valve. You should have a computer diagnostic completed.
