my bike was revving pretty high once it gets warm with no load on the engine i was just trying to figure it out but i was looking for a diagram on the vacuum and breather configurations if they're handy? or any ideas what could be causing it..
Checked the choke isn't sticking on as that would cause high idle. For the breather hoses you might be able to make out the pictures in the FZR400 PDF's that are floating around.
yeah i thought about the choke initially but it's fully operational and closing fully, i've had the carbs off to check the inlet rubbers just in case they were perished like the cam cover gasket (leaking oil from the half-moon part). thanks! i'll have a look.
