  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

All 2st Cold weather engine protection running a lectron?

Just wondering if anyone has tips to protecting your motor from a cold seize? I'm set up to ride the ice but only have maybe three hours on the motor. I run a lectron so jetting should be OK I assume but I'm guessing there is a temp that is even to cold for the fuel rod to deal with??? Anyone know what that temp might be?
Has anyone put something in front of the radiator to block cold air and allow the engine to run warmer?
I don't run a thermostat....thanks for any advice!
 
I cant really help you here other than to let you know these are very popular carbs for snowmobiles as they do well with altitude compensating. Maybe call Kevin at Lectron and ask, he is very nice and helpful. All that said I had mine stick wide open on me last ride. I guess it is not a good idea to wash your bike then ride it in 21 degrees :D

You could partially block off some of the rad, however a bigger problem is carb icing if riding for long periods of time in the extreme cold especially in fresh powder snow. See the following thread: http://www.cafehusky.com/threads/frozen-carb.15486/

Buddy and I went riding in 21 degrees the other day. his engine temp gauge would not get above 83 unless he was pinned for a long time then 97. Might be a good idea to install a thermostat if you ride in cold temps.
 
Having my carb freeze wide open might be the only way I can keep up with some of these ice racing guys lol. A buddy did say they run card board in front of the radiators so that may help engine temps stay up then.
I know in my previous life as s snowmobiler we only got worried about carbs freezing when the temps were just below freezing something to do with moisture and condensation then freezing. Maybe that temp range was more ideal for creating frost can't remember. In any case I'm gonna give it a whirl this weekend!

I pick up your 165 magic machine on Saturday but can't break it in with 20° temps and feel OK about it so I'll be taking the 300..and waiting patiently to pull some wheelies on the WB!

it has to do with the dew point and the flow on the negative side of the slide
 
In snowy Minnesota we use a old inner tube or similar flexible mat'l to basicly wrap around the carb in order to keep the heat in and the snow off!
 
Here is what you need:carb.jpg
Rotax 600 with heated carbs. Carbs are TM rack style carbs though. Coolant runs through the carb body to keep bad things from happening.....
 
So ran the lectron today at 12° F, was a little nervous so I pulled the plug after a little riding and it was golden brown!!! Woo hoo! Ran flawlessly all day! I did install 3/4 length radiator covers and let everything get warm before riding the lake. Everything went great!

Had to leave myself a reminder on my radiator covers lol....

Another thing to mention is that when the weather was warmer the bike never spooged oil when I rode the other day in 12 degree temps it had tons of drool out the muffler. I can only imagine the pipe couldnt get hot enough to burn up the excess oil but just goes to show I dont think the Carb has everything to do with the spooge.

Exactly what is happening. Guys that ride MX never have spooge issues. Woods riders always do as they are off the throttle for long lengths of time.
