In the NE US here, winter is rapidly approaching. We've had heavy rains for a month plus, and temperatures are dipping into the 40ºF range more frequently. I was treated to an excellent weather weekend last weekend, and a buddy & I made the most of it with a good tear - but those 'gimmes' are becoming scarce. The bikes will 'up' by Christmas, and probably remain so until April at the earliest, more likely May - once the rains have washed away the salt & silt that likes to mucky up our corners. It stinks, but it does give us time to get our knuckles busted without missing any riding time.
So, who else is similarly afflicted, and whatcha got planned? I'll go first ...
The Monster: early spring I plan to send the forks off to Traxxion Dynamics or WP for either stage one or two upgrade - sprung appropriately to my weight & riding style, at the minimum. Possibly revalved, we'll see how saucy I feel at the time. Also considering sending my headers off to JetHot for a ceramic coating. Not so much for performance reasons (although a slight added benefit) but mainly to clean them up and hopefully extend the life of the metal. With 37k on them, they're looking the part and I'd like the exhaust to last. While the forks are off, I need to try & re-route my throttle cables, too. I also have a crankcase breather to be installed. And cosmetically, I'd like to have the tank touched-up and a couple coats of clear shot onto it ...
As for the Paso, it's valve service time, and I'm going to use MBP's collets to replace the half-rings. I'd also like to implement the wiring upgrades everybody raves about but that's after I get jfiore's excellent Weber carb upgrades done. The new battery this season has been great, so I'm not concerned with the electricals, but I'd still like to improve upon what's there. But my current carb jetting has gotta go. Cosmetically I'd like to replace all the wellnuts
, as I lost the first one this season. 
Oh yes, and speedo cable #4 needs to be installed ...
What's everybody doing in their downtime? Doesn't have to be limited to your Paso, all you multi-bike owners ...
