Hey all,
my malaguti phantom is liquid cooled and it's always been a little shaky before it heats up. But now when the weather is cooling down it's getting a bit out of control. It takes it over 10 minutes now to stop bogging down when I give it gas, and most of my trips are less than 5 minutes long so it's like a permanent issue now. It's getting embarassing in traffic as I can't count on it not almost stalling whenever I try to accelerate.
Any tips or tricks?
(I got this bike in May so this is my first cold weather experience with it)

You could try to richen up the carburetor's pilot, main, or needle position. That may work, may not. I know my scoots are sluggish if I don't let them warm up for a few in cold weather. They're all air cooled though, so it isn't as much of an issue.
If it can't be solved with tuning, one trick that I see a lot of folks use for cars and trucks is to block off part of the airflow to the radiator. I'd be very careful if you resort to that. If you have a temp gauge, watch it close.

If you have a temp gauge, watch it close. Thanks for those tips! Another idea I've understood is to replace the thermostat that tells the liquid cooling system to kick in at a certain temperature? Get another one that's a little more liberal, and doesn't kick in so quickly? By the way - after switching to 6.5 roller weights the problem is less apparent, so the issue is no longer so glaring. Maybe I should just buck up and live with it until spring comes and solves it  |

A higher temp thermostat may help, but I don't think it would be a total cure either. It might make the symptoms last less time because it would let the coolant reach a higher temperature in the engine before it begins to circulate it to cool it down. The main problem is just getting the engine warm on the initial startup. Your best bet is pretty much a free fix (does cost a tiny bit of fuel).... let it warm up for a few minutes before you ride.
