..for carb icing. I mentioned carb icing on the Ural previously. Well
today I thought for sure that I'd encounter it and would now know for sure
that it's the cause of some of the problems I've been experiencing.
I got ready for work this morning and started to shovel the driveway but I
didn't get far. I was dressed up more than normal, even have a tie on in
order to go to a funeral later today, and the last thing I wanted was to get
all sweaty from shoveling, and the snow was damned heavy. So, after a very
brief go with the shovel I backed Earl out of the garage and started her up.

The night in the garage melted all the snow from the previous nights ride
home. The humidity was high, the roads were wet and it was right around the
freezing point. From what I've been told it's the perfect conditions for
carb icing. Lately I've been taking a back road halfway to work before
getting on the highway, rather than just hoping right on the highway like I
do in warmer weather. After about 10 minutes the left cylinder started
cutting out on me. I pulled over and let the bike idle for a bit until the
left jug started going again, but it didn't last long. I was coming up on
my on ramp so I had two choices, hop on the highway and baby the thing the
rest of the way to work, or point it downhill and stop at the nearest Tom
Horton's for a coffee while I test the theory that the heat from the engine
will melt the ice and it'll run again.
This might be a good time to grab something from Shirley.
I choose the later and headed downhill to the nearest Tim's. After a large
double double I went back out to see if I could get her running right. It
was a struggle to get it started and keep it started. I suspect this is a
result of the after affect of carb icing, water getting into the system from
the ice melting. I managed to get it to idle on one cylinder and after
about five minutes it must have worked the water through and both cylinders
started running strong again. I ran strong the rest of the way to work, so
I suspect that it is indeed carb icing that has been giving me grief on days
like this. Oddly enough, when it's colder I don't have the problem,
probably because of the dryer air.
So now that I know that carb icing is causing some of my problems, I need to
find a solution. I've been told to reroute some of the exhaust into the
intake to heat it up before it hits the air filter, which sounds like too
much work to me. I've also been told the HEET, a fuel additive, may help,
so I'll be on the lookout for some to see if it helps.

Thanks for the tip, I'll check with the wife this evening. Any guess on how
much to add, tea spoon, table spoon, cap full, shot glass, or trial and
error?
Thanks Kuda,

Or just fill up at Mohawk stations (if you have them out there)
Gasohol seems to cause a drop in mileage, but then, so does very cold
weather.

No Mohawk stations out here, do they put the addative at the pumps?

Most (if not all) of the pumps at our local Mobile station in Ayer, MA
pump 10% Ethanol.
