Quick question about dual map switch position

Hi, this might be dumb but just got an 07 ec300 and was curious which position on the switch is for sun and for rain. Up for sun im guessing?
 
Just so we are clear. Skinny/smaller part of switch sticking up = rain. Big part sticking up = sun. ??
 
On my 07 you push the switch forward for rain and back towards you for sun.
You will feel the difference in the pick up from stopped to about half throttle. It is a little snappier with it switched to sun.
Cheers Mark

No, other way around. Push the big bit for sun. The only place I can really notice the difference is, on the rain setting the "edge" is taken off the top end hit. This is on a 250.
 
Well, on mine, then big bit is on the bottom, and there is a picture of the sun by it. The skinny bit is on top and there is a pic of a cloud. Even if you were blindfolded, you could tell when you are on "rain" because there is a noticable reduction in top end hit. ( assuming you could ride far enough without falling off or crashing into something...... have you ever closed your eyes for a time when riding? Man, that is one freaky feeling, but I digress..)

Sorry, I just reread your post. Yes, push the big bit in for sun.
 
Big in is sun, little in (top) is rain. to test, get the engine down in the revs and open it up. it will be alot happier in rain then sun.
 
I removed my switch and wired it in the sun position, soft on the bottom with a huge midrange. Just wish I could get a bit more on top for big loose climbs.
 
What intersets me about this is the number of different descriptions of the effect of the 2 settings. Does anyone know exactly what the mapping looks like, anyone have graphs perhaps?
Obviously depends on individual engine setups - port timing, squish, timimg, jetting, pipe etc. but I would love to see a chart of the actual mapping.
 
Its much less noticable on the 250 than the 300, and unless the jetting is clean it can be masked as well. Sometimes I bump my switch and don't even notice it. I beleive Mark or Steve from Gofasters posted the difference at one time, try a search. It was not in the form of a timing curve however.
 
Any comments on what year/ignition came with this option? I've got a 2004 DE 300 (2k2 stator) and am assuming this wasn't on it. The Kokusan CDI is the same for both the 250/300 and is where the 'switch' would be but not sure if this CDI has that option.

On the KTM's the switch retards the advance curve about 1000 rpms; one of the engine builders I've read about actually runs his race bike in the 'rain' mode so his rev-out happens later (more top end).
 
On my previous '07 EC250, the difference was very subtle as GMP noted. I think one mode was regular and the other a placibo. :D

I tended to leave it in sunny mode to be a happy guy when riding. I was afraid of pushing the rain button and ruining a good day of riding if the rain gods let it pour rain. ;)

I may be confused. But, isn't the "rain" mode a completed circuit and the "sun" mode an open circuit?
On my bike, I removed the map switch and left the two wires unhooked.
 
There is no mode switch on the new bikes. Do they match the "rain" (or the "sun") setting of previous bikes? Or do they have a completely different ignition mapping?
 
The new bikes do have 2 ignition modes. I think the switch is located on the left side radiator hose for transport. My 2011 xc 300 has it mounted on the bars from the dealer. If your 2011 is missing it I would find out why.
 
Even if there is no switch, it will still be an option on the cdi, should be 2 short wires that come out from the cdi, connected or broken is either mode, I think plugged in is sun, but iv been wrong before.

Thanks, I just had a look and it's mounted on the rad hose behind the left shroud. I was expecting to see it on the bars.

On my 2007 Pumpkin 300 :D the "Sun" mode is a closed circuit. Mine didn't came with the map switch, instead under the tank there's a connector to change the ignition curve. For "performance mode" socket connector connected and for "soft" socket connector disconnected. Does GasGas also uses the Kokusan CDI ?

Ok. I checked my mode switch.
SUN complete circuit.
RAIN open circuit.
