Carb icing issues

On the weekend just gone, I was riding my 2000 ZX9R over the mountains near Walcha on the Oxley and had a similar problem with it seeming to run out of fuel... it happened on the way to Gingers and on the way back, both times around the same area near Walcha. It was cool and it was about 1100m in altitude. Another observation was that the bike was running very cold... and I mean very. Discussions with my engine guru have us looking at the Thermostat and the flat slide carbies are running jets that are very suited to the altitude of Phillip Island and Eastern Creek, where it runs very, very well, but are not suited to the Altitude of over 1000m. I am not sure if icing is the problem, but will mention it to him as another possible cause.

just to clarify..why would u coat ur carbs with icing anyway?? i love a good chocy mudcake, with a thick icing..but on carbs?? ewww...

i guess choccy mudcake is full of carbs AND icing??

Yeah in fact I could go a bit of rich choccy cake but I'd rather stay lean.

Thanks again guys. From what you say Buckets it makes sense. Increased altitude=dense air/higher humidity=more mositure in the air that can be frozen on the carbies given the right conditions. For the next month I'm gonna be riding my bike to work around 30km's across the other side of the city so I guess I'll find out how much of an influence altitude has on the issue. Riding in the coldest parts of the morning on the monash at 80kph> where the humidity isn't as high as the higher altitude regions, should determine this. It has never happened whilst riding around the metropolitan or low lying areas before because it hasn't been cold enough (ie. ridden during the middle of the day). Should be interesting anyway.

I think you mean higher altitude = thinner air = less residual heat in the atmosphere = more liklihood of carb icing.

a search for "carb icing dew point" revealed a few interesting articles including this one, also theres a few gems there in the google images, im still at a loss how two girls licking each other has anything to do with a dew point though

[]im still at a loss how two girls licking each other has anything to do with a dew point[/url] though

come over here and sit down mate, and ill explain it to ya

How about "captain Carbohydrate"????

When my 6 does this I just give it a big handful. I've only experienced this on the highway and it has never caused me any dramas coming back to idle. Not much help am I.

Finally got to do a service on the 9 and took off the Coolant Filter at the back of the Carbies to discover, as we suspected, that it was full of shit and blocked.
