    My Trophy 900 t reg has started getting lumpy low revs, after 4.500 rpm its ok. Was fine when I got it, but its not been ridden much (due to a bad shoulder) but I had taken it to a garage a while back (around a month-6 weeks ago) due to this problem, and it sorted it for a while, but took it out today and its awful. Problem is I have a biking trip to france on Tuesday, so no time to take it back to garage.

    Sounds like blocked carbs with gunge. you would be surprised at how quickly petrol goes off now-a-days, theres so much additives to it.Also have a quick look at the vent on the tank to see if not blocked. You could try and fill it with higher octane petrol and go for a long ride to see if clears the carbs for tues??
