johncbr1100 thanks fort he advice never thought of that, but sold the scooter a while ago now as the problem did my nuts in lol, but thanks all the same, info may be helpful for others tho.
clean the gauze disk on the fuel pump thats attached to to fuel pump as its there as a breather and if clogged up you wont be getting the full amount of petrol through to carb. the fuel pump is on the left footboard and the gauze disk is attached to the underside of the fuel pump. this part when u find it should be brass in color and i bet yours will be same color as pump black. clean with a little petrol on a cloth just dab it
I know this is very old but mine is misfiring like crazy. It was runing fine and all of a suden it started misfiring !!! What can it be ??? Changed, spark plug, airfilter etc and still doing it.
More likely to be the wire on top of engine that gives the reading, they come lose over time, if you take it off and tighten it, should solve your problem. X9 owners Club on Facebook if need more help

the rev limiter cuts in at 10 - 11 rpm or about 75mph i finally found out what it was.....the problem was a leaking carb at high revs!
I assumed rev limiter but rev limiter kicks in higher than that, it was a leak on the inlet manifold.
its a rev limiter standard fittment on most bikes now
