Yes I agree with Scoobs, turn up your idle and see if it makes a difference. 1500rpm is a good starting point and then see if you can get away with a little less - different bikes will behave slightly differently largely because the carbs will have slightly different levels of tune/sync.

fist day i rode my bike it was stalling coming up to jucntions and clutch in stuff had my tick over set to 1000-1100

this is too low its now set at 1300 and happy :D

IIRC mine's at about 1300 but I'll up it to 1500 for until it's a bit warmer.
I'll let you know how I get on..
Cheers folks!

Someone should design a carb-heat system like there is on piston aircraft to redirect some of the engine heat to melt any ice.

I remember when I was doing my pilot training I suffered an EFATO (Engine Failure After Takeoff) in a PA-28 due to carb icing in the middle of summer. The dewpoint depression was about 10 degrees C at a temperature of approximately 18 degrees C - prime conditions for icing. Fortunately I landed back onto the same runway.

Now that I fly the bigger type of silver birds - all we have to worry about is bird strikes and terrorists. ;)


I suppose one other way of reducing carb icing would be to lean the mixture - as an over rich engine means the fuel acts more as a coolant which increases the chance of ice. From what I've read the carbed SV is slightly over rich - maybe this is for longevity and cooling reasons?

Dont all the carburrated bikes (SVs) have carb heaters, little brass nipple in the bottom of the float chamber from memory and a thermostat in ther LHS wiring loom??????

Yes but they don't seem to work too well.

My bike has been doing the exact same thing since it became really cold, I even had my throttle freeze open whilst going to work one freezing morning which was frigging nasty, so I tried some fuel additive to stop carb icing and that was problem fixed straight away. I use some stuff from halfords called " Dry Fuel" , comes in a purple bottle , costs about £5 and does two tankfuls.
