hi all, just got the bike running again and although it doesnt cut out, an revs up smooth, it ticks over unsmoothly, it did this before i rebuilt it, and all ive done since is put 120 mains in on the advice of rick oliver, so what, carbs need balancing maybe? opinions and advice please, thanks, sean

Sounds cool.

How warm was the bike and does it make any difference if it gets hotter?

It sounds a bit like mine..and I reckon mine is too rich. Hates to idle when cold and loves a healthy 2k idle when warm.

A sure sign of carbs needing balancing is an uneven idle if everything else is ok.

Your idle mixture may be out, this is adjusted with the pilot screw on each carb. If bike starts cold without choke its prob running rich at idle and may need a 1/2 or 1/4 turn out of the screws. Standard setting from factory is 2 turns out. Check you plugs to get an idea, let the bike idle for a good while and check colour, if dark black then its rich & this may be causing the uneven idle

Although mine does run rich, and i have turned out pilot screws (though not tested it yet coz its only got one caliper on the front) balancing them was pretty easy using a bit of paper as opposed to the small drill bit. Made my tick over much smoother, and the power seems smoother when i roll on the throttle :D

It was warm m8, and was the same from cold?

After i did my valve clearances and balanced my carbs i found my tick over to be alot steadier.

wish id have done the pilot screws when i did the main jets, looks like my first job for saturday! oh, any recommendations at what to set the pilot screws at from fully in with 120 mains, tyga system and k&n? cheers all, sean

I bought a carbtune and an angled screwdriver to do mine.
