Yz 250 wont kickstart
Hi!
You obviously look after your machine and very sensible when laying up, however as you are probably aware 2 strokes rely heavily on compression, A. to produce excellent combustion and B. to draw fuel into the chamber. So when you try kick starting you can't get enough revolutions to draw the correct amount of fuel into the cylinder, where as you push start you constantly turn over the engine increasing compression slightly and bingo it fires.
Can you remember how when kick starting it before this problem the feel on resistance when kicking over? has it now become a lot easier? if so you possibly have worn or broken compression piston rings.
A compression test will reveal this, I hope this sorts your query?

Fuel for yamaha dt 125
This bike uses unleaded gasoline. At only 6.7 to 1 compression you can use the lowest octane fuel you can find. 87 in the US is what that would be around here, but across the pond the octane numbers are different. But don't forget the two stroke oil. That may be more expensive than your fuel cost.
Dt125 cuts out when i put in gear
Hi!
Although the switch is not connected it is still reading an open circuit you need to bridge the wires (Connect/join them) closing it so the inhibitor doesn't cut off the ignition.
If you don't want to bridge the wires try keeping the button of the switch in? Remember however you do this it may come out whilst riding and cut the engine possibly in a dangerous manoevre?? or overtaking causing drastic results.
There you go, sorted!

Cuts out
Does it have a kick stand interlock switch? If so, the stand needs to be up when you select a gear, or it cuts off. If the switch is bad or out of adjustment, it will cut off when put in gear.
