Hi,
I wonder if someone could recommend where I could take my bike for assistance with what I think is a carburation problem. With 1600 miles of running in complete the bike has had what I could best describe as a slight stutter/hesitancy on a constant throttle setting which clears when you open the throttle and accelerate. She runs happily up to this point and you can accelerate through it cleanly too. This problem equates to about 55mph in 4th. My rudimentary experience would suggest fuelling is the issue. The bike is running 12 volt electrics, Pazon Ignition and re-wound dynamo - all seems to be working fine from everything I can tell. The engine has been competely re-built but the carbs have not been refurbished - she starts easily, ticks over happily and runs beautifully with healthy coloured spark plugs - just this one annoying issue on a constant throttle. Pipes are colouring properly and well.
I've tried one/two fuel taps open, I've tried full tank/half empty tank and everything inbetween. Air slide levers don't appear to have any effect on the problem. I haven't touched anything on the carbs yet as it may well be beyond my capability and I'd rather not cause any damage! I have thoughts about cleaning the tap filters - but more in hope than in expectancy.
The carbs are certainly elderly, the slides feel a little "sloppy" in the bore.
So I'm thinking that I need a specialist to help me out. I'm in the South end of Buckinghamshire - anyone got any ideas on where to take it?
Thanks
Stuart
