Rear light stays on + backfire - Page 2

That sounds just like my problem - I must admit I didn't really hang around before setting off. The previous times I had give the bike a good 5 min warm up before setting off.

It does have Keihin carbs on it, not sure if that would make a difference. How could I tell if it's got a carb heater kit on it? Looking through the paperwork it looks as if the carb heater kit was fitted under warranty at some stage but with a change of carb would this be irrelevant now?

Thanks all for your replies so far.

Don't think you can fit carb heater with Keihns (you'd see oil lines going from oil-cooler to carbs), and flatsides are supposed to solve the carb-icing in any case.

try giving it a good warm up and see if the problem goes away. Carbs are metal and transmit cold real well to gasoline.....LOL

It does not need to be that cold for carb icing to occur as air will cool to freezing temperatures as it accelerates through the carb. If there is lots of moisture in the air, that will be enough at this time of year to cause icing problems.

And I was giving it some to be honest. I will test again this weekend if it's not snowing.

Just to let you know that all is great with the superlight now. Neutral light fixed, not a single backfire today and fantastic ride out. She does just over 140 on the speedo and I can even get the front wheel off the floor occationally.

Thanks for all your help

Are you using it instead of weights? Must be great on the biceps!
