2001 Yamaha DT 125 R - Page 2 - Answered Questions & Fixed issues

Carb no doubt needs a rebuild. Dirt, debris, is not allowing fuel in. Check fuel lines as well. No need to do a part job. Carb ports easily get clogged

Does the bike leak oil, if so fix the leak as 2-stroke engine's fuel supply run through engine casing. Check exhaust for blockages. Bike is running lean/rich

Change needle and seat

Only when the engine is not running, alternator should supply power when engine kick started.

try a dealer they may be able to help

service it, thats plugs air filter, check ht cap and lead.if you done that then check spark is good, though if the sparks bad its rectifier or cdi problem, double check batteries good as sometimes they earth out when old.if thats ok its fuel checking time, is fuel getting to carbs ok,,do carbs need a serviceby the way carbs=carberreta

I dont think this is possible. Best you might be able to do is pop the clutch while pushing the bike. A kick start appratus requires not only the part you see and would kick, it has to have internal parts. Your motorcycle is either manufactured for a kick start or it is NOT manufactured for a kick start. If you find out otherwise, please let me know.Thank you

There is a freebie '97 available at:

Otherwise just google it and fossick around, you should be able to find exactly what you want.

Sounds like either the bike is starving for gas at higher RPM's, or you're hitting the rev limiter.

I would make sure the oil level is not too high. Next I would remove a spark plug and test compression to see whether your rings are worn excessively.Hope this helps.

A have a yamaha dtr 125 it runs but its got no power and the valve moves but isn't kicking what could it be thanks

I think your power valve on the barrel by the exhaust may be stuck down so check there first.

Any 2 stroke engine oil will work. I suggest you stick with Yamaha's oil.

It sits in the cutout
unhook the clutch cable and turn the arm back to hook up the spring, then refit the cable

hi.
i am pretty sure that the enduro 250 gets the power for the spark direct from one of the magneto coils. there are 2 coils behind the magneto. one feeds the lighting and battery for the bike.
the other should run through a set of points, through the coil and then to the spark plug.
you should not need a battery at all to start the engine, but you may need to check the points and the coil, and the wires behind the magneto unit for any damage.

If it overheated when the first seal went, you may have a head gasket problem, either that or the seal was replaced incorrectly.

check the battery.. . . i think the battery is lowbat

It holds 1.2 liters.

How much oil did you add? 1 quart or so? If you add too much oil it will rev slow. Let me know and i can help u further.... Sincerely HDTV GURU JAY

check your voltage regulator
