I bought a Kawi ZX6R last year in Feb brand new. As some people will tell you on here (probably Fireskull!!) I'm hardly a fast rider! After storing it for a few months over winter and swapping back to a stock tail pipe I noticed power was right down. I had it serviced as the 4000 mile was due but that made no difference. I then had the servo motor replaced as they thought it was faulty and so not opening the valve all the way in the exhaust. This made no difference either I finally had it dyno'd and the graph appears OK apart from the fact it is only producing 70bhp. This coincides with the fact that it seems to pull away OK but doesn't have the "grunt" it used to. It definietly feels like a restricted bike! The bike has been in a Kawasaki dealer for a week now and they can't find the problem externally so are looking at doing compression testing and possibly then removing the engine to check the engine for cracks, etc as they believe oil is leaking into the engine because they have noticed some smoke coming out when reving hard (I've never noticed this to be honest!). Anyone have any ideas what could cause this? Fuel consumption is roughly half of what it used to be too Waiting to hear back at some point so will update this when I get more. Thank god for the warranty, although knowing my luck the part that has broken won't be covered lol... Talking of Warranty, do people know if labour is covered too?!
