do they sell Xenon Bulbs for the dtr125, or what code is the normal H7, H4 ect??
-
i doubt it will be this but if you have had to redo the wiring there maybe a problem with the ignition mine was the same, i have to kick it and turn the key to the "on" at the same time as kicking and it fires up firse time but if i dont theres a spark ect but wont fire.

hi got it sorted now i took the generator cover off to change the sprocket and just thought id give the wires a wiggle and they started workin again so put abit WD40 to clean out any moister and done the trick.

cheers nice one i just didnt want to have to get a new gasket and stuff if it had fluids in ill go give it a go now
-
ye but wouldnt you have to drain any fluids like on the other side theres the gearbox oil, wasted to know if you could take the sprocket off without taking the cover off if i would have to drain anything, and the chain if jammed between the sprocket and the swingarm

awhile back i had a problem with all the electrics as the back indicator had been smashed so didnt work then everything stopped working, discovered that all the wires under the seat had melted together( shorted out from indicator i think) so after hours and many lenths of wire fixed all the wires so everything works fine now, horn, alarm, lights ect.
the problem now is the neutral light and oil light dont work anymore, iv looked at all the rest of the wires under the seat and headlight but there all fine, could it be anything to do with a relay or something, or whatever detects its in neutral from the gearbox? thanks 4 anyhelp in advance

long time since last post but thanks for help, i took top end off and piston rings were nackered so changed them and polished all the carbon off the head and piston and also put a 17 teeth sprocket on front and now it is better then its ever been will reach 70-75 and will go off the clock downhills not even red lineing no problem. before it wouldnt hit 55 even downhills then would cut out (rings i think loosing the compression) just run it in and is sweet as a nut thanks

Found the bike to be very pleasant for riding around town so far. On a longer journey it obviously gets a bit mundane hovering around 65. However it gets me to work much quicker to work and is a pleasure to ride. Very responsive with what to me feels like good low down pull. So up to 40 in town situations it doesnt really need to be any quicker.
Only problem I had was a faulty speedo sensor. I had read of this on various reviews so it was expected to happen. A new sensor got fitted and it has been fine since. Not too much of an inconvenience as I pass the bike shop every day on the way to work. I have now covered approx 700 miles since ownership of the bike.
i had same problem but i jsut waved a magnet infront of it and its been fine ever since

this is because when the engine is on tickover the lights are powered by the battery but when you rev more power is going thought the battery to charge it so the lights get slighly more power, totally normal but cant help with the manula sorry

i have cleaned out the exhausts and also cleaned the spark plug and set the oil pump as it was giving to much oil thought and the accelaration has improved but top end still at around 58-60 then as soon as it hits 60 the revs just bog and die, i tryed lookin up the exhaust port to see how the powervalve was set but couldnt see it, the pistion seemed really shiney on the surface didnt look clogged, how can you tell is it is coked or not? cheers
-
i rang a yamaha dealership colin appleyard and they said it may be a faulty ignition barrel so ill have to take mine off and see what the connectors are like as im not sure what year the barrel is as the ones iv looked at have different connectors for different years
-
i dont usually abuse it only got it to 80 twice to c whts it could do usually stay around 65 but its been built from different years so the clocks say 6000miles but engine might have done alot more, im not very mecanically minded is a rebuild sumert you can do yourself or best in the shop?

DTR125 Ignition problems
in Dual Sport, Offroad Bikes
Posted
Right got the bike stripped down. Its a yamaha dtr125 1994 model with powervalve. but wont fire up, its got fuel in and theres a spark but heres the problem.
Theres a spark when the ignition is not on but stops when ignition is live.
So ignitions on and all lights, temp guage and powervalve works but theres no spark, then cut the ignition and theres a spark and it fires up for afew secs then dies again. Had this problem before it got stolen where the spark would sometimes stop and to start it you had to flick the ignition on while kicking it over. Could this be something simple ignition coil? or would a whole rewiring be needed? Also the nuetral light stopped working jsut before it was stolen which im sure is something inside the generator or gearbox that is causing this?
That can be solved later but atm i need help on the sparking issue to get it running propely??
