  1. Engine rattle/piston slap query

    The Rocket is 7 months and 13,000klm old. When cold, at 1800 revs there is a loud rattle noise. It appears to stop at 2000 revs and appears to go away when hot. The dealer is yet to investigate ( 4 weeks booking time). Question - has anyone else experienced this symptom?

  4. Engine Issue

    2014 Roadster. It sounds OK at idle. Off idle to about 2500 rpm there is a distinct miss. It starts smoothing out at 3000 rpm and runs strong and smooth to redline. In addition to the miss, there is an extra noise coming from the exhaust pipe. The pipe is a 3 into 1 baffled megaphone...
  5. Check engine light automatic at 600 miles?

    Hey, my check engine light came on today but I looked down and I was at 599 miles. Is it set to automatically come on at 600 miles to tell you to get your first service or do I need to get more concerned it's something real? Bike is running normally.
