Can ne1 tell me any info on the power valve in a mito, how it works, how to set it up etc as i don't have a clue. it is worki as when i turn the ignition i can hear it .
Cheers luke
I could be really snotty and tell you to go read the archives, since this has been
discussed any times here. But instead, I'll be nice and give you a brief answer,
and then I'll tell you to go read the archives or do some research on the net
about power valves. Most modern 2 stroke bikes have some kind of power valve,
so there is los of general information about them.

The physics of 2-stroke motors is such that if the exhaust port is big enough to
make maximum power, it is too big at slower engine speeds and the engine will not
run well. The power valve is a fairly crude mechanical device, that simply acts to
partially close off the exhaust port at lower RPMs to improve low end performance.
On the Mito, it is either open or closed (some have multiple stages). No in between.
The noise you hear when you turn the key is the power valve cycling itself back to
the open position. Although not the purpose, hearing it is a good audible check that
it is working. Adjusting it has been discussed here ad nauseum and is laid out in the
manual, so I won't go into that except to say there is only one adjustment necessary,
and that is to make sure there is sufficient clearance to the piston so you don't snag
the piston or a ring.

Now go read the archives or do some research.

Hi !

If you take of for some reason the CTS-cables, remeber to do this:

Remember to do once a Cheking turn for the CTS-Actuator BEFORE you install back the CTS-cables.
CTS-Actuator MUST BE in it's "ZERO POINT" before the CTS-cables are installed, in any other case it will destroy/BURN the Actuator and/-or CTS-Computer unit.

It's easy to make the CTS-Actuator's cable Pulley/disc to move while moving the cables from it in some cases...and that will make problems later on if Re-assembly aint done like it should be.

bye ! and have fun.

Hi !

some weeks ago i opened up 1 of my broken CTS-computer units (model 7250 rpm.) For some years i have been wondering what it looks inside, so finally i decided to open it up. Blody small elecrics inside, no hope for fixing.. ?

today when i was looking at French SC forum once again, i noticed that some1 else had done the same thingy, so here is a direct link with some nice photos
