In the mornings on my way to work the first mile is always really rough. Engine chugs like it's stalling and is rather "rocky" nearly came off in a corner because if it and on 3 occasions the engine has killed itself! (once on a major roundabout!) I've only ridden in winter so don't know how summer will be!

Bike is on 3k miles so well warn in.

Is anybody else having cold running issues as the dealer haven't heard any reports of it as of yet!

How cold are we talking? When I leave work at night sometimes it is below freezing and she hasn't given me any trouble at all.

5 degree has been the worst so far! It never does it after work, only in the early morning! Knowing me I've got a faulty engine!

I've had this happen to me as well. I found that letting the bike get some heat in it before riding (usually about 2 bars on the temp gauge) has stopped it. I think it has to do with the air/fuel ratio. Colder air is thicker which requires more fuel which could cause a issue if the mixture is not right.

Yep - if it's that cold, spend a little time on warm-up and get some zip-ties and cardboard (or duct tape) and block off (no more than half) the radiator to help keep more heat in the system. Something easily reversed or modified on the side of the road if you start running hot. Consider the cooling system is designed to be able to dump heat at 120+ degrees ambient. At 50 mph and 5 degrees, you're sucking heat out of the system fast - maybe faster than it can be replaced. The R3 is mapped rich from the factory, so normally cold air is a good thing as far as AFV's, but if the engine is not kept at 185+, it will likely run rougher than it would otherwise.


At 5 degrees, you are operating on the lower end of the 'normal' range, so there will be issues. Consider a winter weight oil, take the time to warm it up, take a little air out of the tires, and be careful.

Try a moroso external hearing pad http://m.summitracing.com/parts/m...c-af8zjT10ycW6nSlLTWyw16mIpky-MEhsaApRd8P8HAQ we use those on our yanmar diesel fire pumps in the winter. If you can find an outlet where you park at work should come in handy if cold starting is the issue.
