    have same trouble myself. goin into roundabouts etc. tryin to get used to keeping revs higher up using first and second longer and more frequently. doesnt help you much but thought i'd mention it!

    Guess your bike is running stock gearing - Needs a minimum of -1 of the front and possible +2 on the rear.

    Also worth having the throttle bodies set-up properly

    from what the guy said to me when i brought it of him its got one less on the front and 2+ on the rear.

    bike is with a running with a power commander it has been on a dyno for a run but i dont think it has been setup.

    It's a twin. it has two less cylinders than a four, which are at least twice the size. it only fires twice every two crank shaft revolutions instead of four firing pulses every two crank shaft revolutions. that all adds up to lumpier running at low RPM. thats the whole point, its a twin. if you fancy trying something really special try a 650cc single.

    lunatic machines. my dominators 18 years old, looks a mess but what a grin factor! would recommend a big trailie to anyone as a second bike. good for winter blues too. rain or not i'm out on it.

    being in scotland beside Loch Lomond, my back gardens full of back roads and green lanes so be rude not to use em. neighbours got a ktm 450 and he's mental on it! (must be summat about em. gives you a chemical imbalance!) best of both worlds. cant be a fair weather rider up here, only get 3 weeks of summer!!

    As Mr V8 says,

    16 front, 44 rear is the most popular combo. If youve got a brand new standard chain, doubt it would work, if youve got a few miles on it your normally ok
