Thanks for the help guys. I've been riding for over 30 yrs, anything from a VFR750 to a Honda 250. In all my riding time I've never had such a sensitive throttle. This is my 1st Fazer, the bike is great apart from the throttle. Yes I am a big guy but have been most of my life, suspension is adjusted accordingly, it flies round corners beautifully and I can still scrape my boots on the tarmac. The throttle is not jerky, infact it's quite smooth but perhaps not as progressive as the VFR. I've just been and checked the throttle free play and its 4 mm. I have altered it to see if it makes any difference but it doesn't. Carbs were balanced last month and idle speed is around 1200 rpm. I've looked at the cables and you can turn the throttles by hand on the carbs, it's as though the springs are too slack. I've even tried riding without gloves, ( not recommended) other bikers at work have tried it and said they thought it too dangerous to ride although the MOT guy said it was sensitive but ok. I'm going to attach a spring to the throttle at the carbs to see if I can make it better, I'll let you know. Any other suggestions gratefully received.
