    I have a 2004 switch back 700 and when im riding it runs fine for about 10 min but the second it warms up and im hammering on it the det light comes at about 80 then goes off and come back on again around 80 if I let it sit for a se it runs great any idea what the hell my problem is plugs are brand new and run new gas line from the tank to the carbs because I thought that they might be sucking air at high rpm also it does it in powder anywhere last year i didnt have this problem and didnt have it at the first of the year cleaned water traps on carbs and also drained tank completely also check termostat works fine

    Try running a tank of premium and see if it goes away.

    Sounds like either bad fuel, or an air bubble in the coolant system. The det should only come on and retard timeing due two things. Over temp or crap fuel. Had this once or twice on my switchback in the past.


    Cheers

    mine did this also, ended up i was losing coolant slowly, there are 2 retainer clips that hold the antifreeze manifold to the block underneath the y-pipe, one of these reatiner clips was missing.
