I'm 90% sure by the way my bike runs that its got bigger jets going on.
Its slightly lumpy on tick over and lowish revs but when i hit just under 4k she decides to pull like a rocket.
Ths makes some of the slower manovers a little trickier.

If i'm to look at the carbs etc how can i tell whats going on?

The bikes a 1994 american import cbr 600 btw

Thanks
