Hi, I've got a bit of an issue with my 94 1100WR in that the throttle stutters heavily between 1000 and 4000 revs. It could possibly still be doing it above that but the frequency gets to a point that I can't clearly tell. Anyway, I've been advised that it could be my emulsion tubes that have worn out to an oval shape and no longer fit or function correctly. How do I check this? It sounds expensive too... Any advice? Cheers SPLAT
