te310 - 2012 - cold start lever

Hi Guys,
Is the red lever on the TE310 2012 a cold start like a choke or a hot start? What's it purpose and how does it work? I notice it's not on the 2013 model.

The reason I ask is that mine got stuck on the weekend and the bike was reving too high until I worked out what it was and moved it in and out a bit to loosen it up. Obviously I'm not a mechanic, but I do like to know what I can about my gear and have gotten familiar with most other parts of the bike by now.

I've never needed to use this lever, it always starts without needing it.

It's part 29 from the manual - screenshot attached.

The description in the manual for 29 is 'lever' and part 5 which looks to be the cable is 'Starter trasmission'. I'm guessing this is typo, as you would know the English in the manual is a bit broken.



Cheers

Yes, it is a cold start lever. Used to warm up your bike when cold only. When warm it will make it idle high. Like a choke for fuel injected bikes.

It's basically a high idle lever. Not exactly a choke. I don't think it makes the mixture richer at all. The temp sensor determines the mixture.

For a cold start, It's best for a cold engine to idle high for a while.
It pumps the oil through a dry engine quicker and keeps the cams from galling in the dry plain bearings.

It is sometimes useful when starting the bike after a pop stall too.
Clears out the unburned fuel in the system.
Works when you bust a throttle cable too.
You can ride home on it.

Thanks guys, some good tips there R_Little, much appreciated.

Hello !
Any idea how this lever works? On my bike ( 2012 TE 310) I found that this cable was broken, and have no idea how it previously was attached. I've bought a new cable, shortened it, but I'm not sure where I have to make the end nipple on the bowden cable. I've saw that it has a spring that pushes a bolt, and when the bolt is open more air comes into the mixture and the idle is higher. The nipple should be installed before the spring?
Thanks
