My dtr 125 wont start
too much fuel buddy on carb is a mixture screw turn this in 14 of a turn or more if required and try this if no good get back to me
I have a 2002 plate
Has the power valve seized on as that will restrict the revs.
Hope that helps.
Hey i was riding my
hi ,
Depending how old is the bike it maybe only your speedo cable gone .
There is no need of replacing the speedo even if its a new bike as the connection maybe damp or fuses might be blown or false connection
I have put a higher
I doubt the high grade of gas has anything to do with not starting, what I suspect is your oil injection reservoir tank is low and the sensor is shutting off the ignition
Hey there, you seem to
Where is the black liquid? In the fuel tank? Over the engine?
Please explain where and what you think it is.
I presume it passed the MOT and it isn't someone who is jealous of it.
Thank you

Hi I keep getting a
Since you do not give any details we will just make this as generic as possible to try and help.
Check all panels and cover plates to make sure these are secure. (especially any loose screws)
Check the spark plug(s) to ensure these are tight.
Check cables to make sure all are secure especially near the engine.
(clips and holders come loose and sometimes rattle as they dance around to the engines tune)
Spark knock does not sound like a rattle. However you can try using a higher octane to see if things improve.
Check the battery and make sure it is secure.
Hope this helps.
About all I can think of right now.
Good luck!

It is pretty easy. Remove the old points then install the new set. There is a slot where the lockdown screw goes. The slot limits the adjusting range yet allows the adjusting plate to move left and right to set the timing. The lockdown screw gets snugged up just enough to hold the points assembly in place so you can stick a screwdriver inside the flywheel and into the adjusting point to move the entire points assembly. Moving the sssembly makes the timing earlier or later. A dial gage is screwed into the spark plug hole to gage the position of the piston. The timing should be set such that the points open at 1.8mm BTC.. An ohlm meter will show you the moment the points break contact. You can check the timing with a timing light if your particular machine has an index mark on the flywheel and a static mark on the case. Not everyone has a dial gage, Ohlm meter and timing light. In general, set the points gap at .012 to .015 and you should be about right. The gap is set with the arm riding on the high point of the magneto center lobe. Please take a moment and rate my answer. Thanks.
I have a offroad dtr
Check the wiring exiting the crankcase up to the rectifier/CDI unit and ignition coil. Look for excessive squashing, pinched or burnt (very stiff) wiring. Check all connections are firm and free of corrosion. Ensure plug lead is not arcing to frame or engine when in place. Make sure ingition coil is FIRMLY earthed at mounting point. A good tip is to run an earth wire from the head bolt to the frame. Thoroughly check any "kill switch" wiring as moving handlebars, throttle cable etc whilst kicking over may interupt electrical circuit. It is common for wiring to eventually get caught up in the steering "stops" on the lower fork clamps, cutting or severely damaging wiring. The wires exiting the crankcase come from the generator and without a rotor puller they will remain unsighted behind the generator rotor. You can easily remove the cover however, and check grommet where loom enters for pinched or flattened wires.
Check the site below (scroll down for your Model/Year) It has exploded view diagrams of all the pertinent parts to see your bike going again. Cheers.

I have a dtr 125 its bogging out before the
i have the same problem. i have recently bought a 1998 dtr, but when we had a closer look at the engin, it wasnt worth keeping. so managed to get a 2006 engin. i fitted this. but the bike seems reallys slow. I then opend the powervalve. but the bike boggs out just as i get in to the power band. i was told to re jett the bike to a 260. so will be getting that done soon. will tell you what it goes like mate.
I have a rxs but it back fires and stops power at 35/40 mph
With the rattle, i would true the crank. Was there ever an abrupt stop (chain came off and wedged, locked up back tire, etc)? That would indicate crank.
If it had points i'd say they were floating.
Sometimes a plugged exhaust will limit power at a certain rpm, but not explain the rattle (i'm imagining vibration, but it could be something benign). Good luck.

you should check the cooling system if you don't have one then your gonna have to deal with it unless its something else its a different problem but that happens to my 3 wheeler that has no cooling system
Loss of power...
hi kev,
thank you for using fixya.
i'm a 2-stroke fan myself, all my bikes are 2 stroke. with the issue you currently have, i would say that the culprit will be the following.
1. carb mixture for oil, air and gas. you may need to have this tuned making sure that the 2-t oil is not more than the gas.
2.
body {background-color: #FFFFFF;font-family: "Verdana"; font-size: x-small;}
p { margin: 0px 0px 0px 0px; }
overheating, there are many points for a 2 stroke engine to overheat even on
in idle, one reason is too much oil or too little oil (transmission oil that
is). when it overheats, the gas/oil/air mixture will be heated and too denced to
burn, leaving it with low combustion and smokey burn.
best way to get through this is to check your piston and rings of any scratch
for a possible blow by, and have parts replaced if possible. for the carburator,
just set the timing and the tuning to 1:4:5.
should you have other questions, please let me know.
regards,
voodoo
