Throttle response
« on: December 10, 2020, 03:32:30 PM »
Hello guys and gals
I've just  got a long-stored 350/4 running again.
Carbs cleaned, electronic ignition fitted, new plugs/filters. That kind of thing. Nothing major.

Tickover is nice, but opening the throttle and she's a little bit hesitant. Not 'snappy' like my 550.
Once all the cylinders have 'caught up', it revs out nicely. Sounds bloody lovely btw
Engine lovely and quiet so tappets/cam chain are prob ok.

Does this sound like carb balancing?

Maybe it just needs a good run, but I'm going to put on new tyres first. And wait for the rain to stop.

Thanks team

Unless it was seriously offset to give great variance to balance, then carb synchronisation wouldn't usually affect the speed of response to any degree.

Have a look to verify the idle airscrew settings as they are in comparison to the manual. Where have they been set in turns out from closed?

Then also try it with the screws set 1/4 turn further inward to see if it improves the pickup speed.
