How long

[flynrider]

I start my bikes at least once/month in the "off-season". I try to ride each one for at least 10-15 minutes each time I start them.

That is a good practice (i.e. riding them). Air cooled bikes need to be brought up to operating temperature after a cold start. When cold, the clearances between the piston and cylinder wall is greater, which allows moisture (product of normal combustion) to blow by into the crankcase. Letting them get to operating temp purges that moisture. Just starting briefly and shutting down is actually worse than not starting it at all.

I think the longest has been a month or so (pushing a month again) as I try to cycle through the bikes, using one each weekend. Weather tends to muck that up a bit.

Two months in the shop after getting knocked off, but if we don't count that then I have gone for two weeks maybe twice.

Longest has been about 2 weeks. I start it once a week if the temp is above 20 or so, letting it warm up to about 195 or so (I check with my pocket IR thermometer), then I let it cool down a while, then run it again for a couple of minutes idling in 2nd while on the center stand.
Last time I was able to ride was Christmas Eve before all the snow came.

Weather permitting I try to take the CB for a short spin 10-15 miles at least once per month during the off season (Nov-March).

Mine has been sitting since delivered back in August. I had some unplanned surgery that went very well a week later and it's taken all this time to get strong enough to handle a bike again but I will ride it for the first time soon, early March. For now, she has fresh fuel and fuel stabilizer and I start her every few days.

I park all my bikes around the first week of November and won't start them again until early-mid April - unless we get an unusually early spring which is not likely.

I love the Cb more now than when i first purchased it. Originally purchased it as a commuter bike but now my triumph street triple is the commuter bike and I ride the Cb on special occasions or if I feel like just crusing and really enjoying the ride. Its been 3 weeks since my last jaunt with the CB...

Maybe a month once a year. My problem is getting to the main roads (1.5 miles) if they dont clear our road.
