I have a 1983 suzuki gs450 ran great till today. Started fine and was letting it warm up and it died, went to restart it and it wouldnt stay running unless I gave it gas didnt think much of it till I went to ride it an then the fun started. it was idling fine but when I got going no power till 4000 rpms then it surg to 6000 rpms, then i stopped and started out and did it again. took it home check the air box ,fuel line and spark plugs they all look good. I thought maybe carbs need cleaned but it idles fine and if I have it on the center stand and give it gas it will run fine and will go thru the gears and will rev to redline no problem, any idieas ( carbs where rebuilt about 350 miles ago)
