Cold weather start - XR650L

31 posts in this topic

Hey boyz,

Haven't ridden the L in two weeks, and I can't get it to start. It's -4 celsius (24.8 Fahrenheit) today, so I thought it should still go. I thought it'd be okay til about -10, even though the manual doesn't say anything about starting below zero. How do I get 'er going? I don't want to choke it too long in this crappy weather.

Easily and expensively solved with a pumper carb.

Back when I was running the stock carb I would have to dribble a little gas into the carb throat when the weather was below freezing- I know dangerous, but at least it got the beast started.

I managed to get it going. I cranked the throttle wide open, then let it sit for 20 min. It backfired once, then started right up. Let 'er idle 20 min. Still, it's better to winterize it, I imagine, rather than starting it once per week.

Don't know why, but the XRL responds well to draining the bowl after its been sitting awhile.

Especially if you're serving it gasohol.

I think I'm going to insulate my garage door and try to keep it at about 5 celsius in there. I thought that the cold might actually slow down any rusting, etc. On warm-up days, I'll bring the temperature back up, then start it.

How do I insulate my garage door? Someone said you can buy strips of insulation that just fit in the slots of the door. Is that right??

Draining the bowl works for me, too.

Try a home improvement store and get some rigid foam insulation. It comes in different thicknesses and sizes. It shouldn't be to hard to install in an noninsulated door.

Is your bike stock, IE stock pipe, Carb etc. I did Daves Carb mods and bumped the pilot jet up to a 55 and the main up to a 165. It starts very easy now. The stock XRL is very lean from the factory and this doesnt help at all for cold starting.

Mine has been rejetted and it can still be hard to start. That's if it sits for a while (2 weeks outside). I found if I do not full choke it right at first, it will fire up pretty easy. I can full choke for a second if if did not fire right away. It a matter of finding the right combo. I think I found mine. It's a 2006 with about 1200 miles on it. About time for Honda semi-synthetic oil.

Off to another subject for a second. Which Clark tank size do you guys prefer?

4.0, 4.6 or some other size or brand. I found out Clark is local, so I would prefer

them. :applause:

Back to cold weather starts - I suppose the Edelbrock pumper is the way to go? How $$ do they cost??

Note: my dealer told me that it's not appropriate to winter your bike by starting it once a week. Said you should do a proper winterization. Is this generally the case?? Will the carb still get gummed up? I suppose cold gas sitting in that carb could cause a few problems....

I always added " STA-BIL " to my gas tank, (available everywhere), run the engine a bit, shut off gas, and let the engine die after it empties the float bowl ... never a problem

This thread has been quiet for a while but I will in my problem today. I live in the desert and it was 34 degrees this morning. I loaded my 2006 XR650L in the truck an met my friends out at the riding area. My honda and a kids CR50 would not start. My bike would not even try to fire up. After taking off the air filter, gas tank, and un hooking the gas line and smog filter it fired up.

Did I have some type of vapor lock from the cold?

Personal choice really. It surprises me how quickly the 2.8 gal tank goes dry. I just ordered a 4.7 Clarke as this should give me 4 whole gallons for cruise, and .7 or so for reserve.

The Clarke 4.0 is only 1.2 gallons more than stock, and stock doesn't last very long, so it just made more sense for me to get the larger one. I didn't want anything like a Baja tank of 6+ gallons as that is a lot of weight/bulk.

I *REALLY* want to get the factory graphics for the tank. Anyone know how/where to obtain the 2006 XRL tank graphics?

I have found the gas loses some of its volatility after sitting in the carb for a while. When it does fire there is the dead gas smell for a little bit until the carb cleans itself out. Combine that with a battery that can't turn the motor over as fast with the colder temps and thicker oil and starting suffers. I am with the guys about draining the bowl to better gas to the engine quicker. :applause:

No doubt.

On my 250R, if I unscrew the bowl drain screw, the gas looks like tea when it comes out, if it has been sitting a while. Once I turn on the petcock, the gas turns from a brown tea-color to almost clear in a second or two. Replace the bowl drain, turn the gas back on, let the carb bow fill, fires up on first kick.

I usually avoid commuting on my 650L when it gets down to 15F. Anything above 20 degrees F is okay though. It did fire up once at -10F (-23.3 Celcius) but I pussed out and didn’t ride it.

The only thing that puts up a stink is my starter motor. It sounds like it has a dried bearing. It makes a lot of noise but the bike still manages to fire up.

I’ve even gotten one of my ATK605’s to fire up in the cold. The starter wouldn’t even turn it over. I had to use the left side kick starter.

So Jayzonk, why would you want to ride when it is that fing cold out??? :applause:
