K7 GSXR600.... This is a random problem that seems to happen after a short ride, the bike is stopped and then is ridden again shortly afterwards (so the engine is still hot).
What happens: Between 4 and 4 1/2 grand (2nd & 3rd gear), the bike will suddenly pick up revs & speed (without any throttle movement) and then when I slightly back off the throttle to slow down (I'm talking about a mm of movement), it's complete engine braking & I can come to an instant stop.
Also, when I'm trying to be as smooth as possible around this rev range, it starts to sound like it's dropped a cylinder for a few secs, and has just recently started to 'jump' with the revs (kinda like doing bunny hops when you aren't trying!)
The only thing that seems to stop it for awhile, is if I hit the engine kill switch, coast for a few secs and then jump start it again.... then the engine runs smoothly from then, or the problem will start in again a few k's down the road. Otherwise, I just have to ride through the problem until it disappears.... which isn't fun through tight twisties, when my bike is either all or nothing.
I've taken it back and forward to the dealer/mechanics I bought it through, but they haven't been able to find anything on the plug-in fault reader & (of course), it hasn't happened to them whilst test riding it. I would start to think I was going crazy... but a friend took it for a test ride & confirmed it was happening & that it was blimmin dangerous.
Does anybody have any clue what it could be? Or any recommendations of good Suzuki mechanics in the Akld area? My mechanics have been awesome with trying to sort it out, but are hitting a wall with ideas.
