I eventually started my wifes VFR after 3 months of not running, bike is running fine but the exhaust is popping at high revs, almost like its missing but the engine is running fine and during a 20 minute run today was pulling like a train.
As it was running fine before it was laid up i dont think its a jetting issue
As its running and pulling strong I dont think its electrical issue
Any suggestions at all? bearing in mind the bike is running fine
Popping after lay up

Top the tank up with some fresh petrol & take it for a long ride, should clear it out...

20 minutes was more than enough today as it wasn't exactly warm and the roads were in a right state!
If it's half decent tomorrow I will get properly toged up and go a decent run
