I have been having carburation issues ever since I got my KZ13. Cleaned , cleaned and cleaned agian and still no joy. Desparation setting in as Rally coming up fast, what can I do. Then at our recent Kettle Clinic Rally I remembered seeing mizzy had aquired Scotches Carb cleaning tool, so I asked if I could possibly borrow it. Like the true gent that he is he agreed and sent it through to me. So off come the carbs again and methodically follow the instructions. Rebuild the carbs and fit. Start up and balance and colour tune. Well didn't get chance to road test until today. WOW I'm blown away. Smooth instant pick up, no stuttering and idles perfectly. Also fuel consumption much improved on our 200 mile round trip. So all I can say is you've made a fantasic tool that does exactly what it needs to and I'm ecstatic thank you
