Solved - rough running on 05 Gen 1 1000

Thanks for write-up, Nellog. Good to hear stories. What precisely were the conditions and symptoms of your fault? My fault is this - under heavy acceleration the engine produces less than full power and then there's a step-up as full power comes in. I can't honestly say it's running *rough* as it doesn't feel or sound particularly rough. But I know there's a fault because of the surge in power after 0.75 seconds or so. And the surge is so digital (binary - not gradual at all) that it seems to me most likely to be electrical. However, when I checked my records it seemed the bike was in desperate need of a service so I stripped her down and I'm currently doing a full service - valve shims at the moment. But carb balance next. You've got me thinking about the EXUP too though - I suppose if that were sticking it would explain the sudden step up in power when it flicked into the correct position... do they actually move that quick?


Still, I'll get her back together and go for a test run - if it's still there I'll have a look at the EXUP.



Cheers,
