I'm in Vancouver Canada and ride all year round. The weather here stays rideable a lot (as long as you have good rain gear), but I've found that on cold days with medium-to-heavy rain it's hard to keep my SV's engine running. It wants to stall badly if the revs aren't kept up around 4,000. I've considered fabricating some kind of sheetmetal thing to cover half of the radiator so that it doesn't get too cold, but was wondering if other riders had dealt with this problem. Idears?
