Hey everyone,
I purchased a 97 Formula 583, this past summer and have been playing around with it. It idles around 4000rpm which is high, but when you give it throttle it goes like a bat outta hell. Recently it has started bogging when it get hot like 1-2 km down the trail it will still idle at 4000 but once you give it alittle throttle it will die. If I let off it comes back. If I give it a quick shot of primer it will go for a minute and die back again.
I have cleaned the carbs 2x, put on anew fuel pump, new carb boots, new fuel line on carbs to pump. Sprayed wd40 down by the clutch (no idle changes).
Any advice would be great.
