Hi all,
My rotary has developed some odd symptoms and I wondered if anyone else had seen this.
When I start the bike it runs fine for a minute or two and then seems to intermittently drop the revs down as though one rotor is not running right. Once fully warm it is OK again. I have also noticed that opening out the bike a little harder in the first few miles of riding it causes a bad, clattering misfire. This misfire goes away when the bike has been run a dozen miles or more.
I remember the idling issue a couple of times previously. I fixed it by changing the plug once and on another occasion the bike was put into storage at the end of the year with oil in the rotor housings – there was no problem when I started the bike the following year. As I’ve tried the plugs I suspect a sticking rotor seal. I remember being told at Shenstone back in the day that it was sometimes possible to free stuck seals by leaving the engine soaking with oil in the rotor housings, which may explain why it went away previously…
Bike had been running fine prior to this issue.
Anyone met this before and if so how did you resolve the issue?
Thanks!
