emilz23 Posted March 23, 2013 Share Posted March 23, 2013 Hello my dear Yamaha fellow So, in last year, when moto season was going to the end, my lil' yamaha was started to have problem with "coming to live" aka starting up. I tried to figure out, whats the problem, but no success. So I parked and prepared my yamaha for winter. So, in recently days, I found myself that spring and moto season is not far, so i get my yamaha out of "winter sleep" and started whatcing and searching for the problem. Me and my dad feagured out, that problem may be in starter, so i take out starter form under of engine and opened it. It was full of dust and black inside. Starter coils was in very dramatic situation, too. So I cheanged them. Starter now worked as new. I pluged it in engine and screwed it in place ... Seted up all, and started up motor. It was like starting, but then i saw interesting thing what happened. On CRANKSHAFT ASSY there are Magnet (in generator) in end of assy and before it is big gear (nr 003) who is connected with smaller gear (nr 007) - this little gear is incisioned by starter. So after clicking "start" button on handlebar - the big gear is srating to spin and in the second (if magnet is in real place) starts spin with magnet together and starting engine (from sound i can tell it) ... And if i release "start" button the magnet stops imeadetly spinning, but the big gear is stopping far more slower (as wheel in the air if we spin it with power - and after we release it, it keeps spin) ... After than, i push "start" button - it keep starting engine or spins without magnet and not starting engine (not moving crankshalf) or fuses starts them work and I cant start engine, because from (http://www.oemmotorparts.com/oem5.asp?M=Yamaha&T=DT%20X%20%20125&Y=2006&L=YA-DT-X-125-1&O=BATTERY&F=YA-DT-X-125-1_BR&L2=YA-DT-X-125-1_BR nr 015) is not allowing it .... So where is the problem why the "big" gear and magnet are not starting and stoping together - when i push or realese "start" button. How i can fix it? Pic in here - http://www.oemmotorparts.com/oem5.asp?M=Yamaha&T=DT%20X%20%20125&Y=2006&L=YA-DT-X-125-1&O=STARTER&F=YA-DT-X-125-1_AL&L2=YA-DT-X-125-1_AL Model - Yamaha DTX Engine - Yamaha 125 cm3 (2 stroke) orginal from DTX Year - 2006 Parts - +/- all orginal. HELP! P.s. And is it possible to put kickstart mehanism to my Yamaha DTX 125'06 from Yamaha DTR 125 '04-08????

Moderator Airhead Posted March 23, 2013 Moderator Share Posted March 23, 2013 are you saying that when you press the start button the starter does not turn the engine emil? Link to comment Share on other sites More sharing options...
mike1949 Posted March 23, 2013 Share Posted March 23, 2013 In all honesty Emil, you're biggest problem is trying to communicate with us, I personally don't understand a word of what you are saying. Sorry. Link to comment Share on other sites More sharing options...
blackhat250 Posted March 23, 2013 Share Posted March 23, 2013 Starter cluch isn"t engaging,, by the sounds of things, Link to comment Share on other sites More sharing options...
emilz23 Posted March 24, 2013 Author Share Posted March 24, 2013 @ AirHead - As I sad - When i press the button, when the big gear and magnet are in right place , starter moves little gear, little gar moves big gear, big gear moves magnet, they together moves crankshalf - and motor is trying to start, like it does when all was right. But, when the big gear and magnet is not in right place - the big gear is just spinning for no reason - nothing happen, only that big gear spins OR if fuses starts working, and that little thing, where "+" wire is going to battery and wire who is comming from starter and multiple wire who are goig to CDI, where fuses are located at - are making "click" noise when i press "start" button. .edit - if i mannualy get magnet in right place it is starting motor. But if i realase button in wrong moment and big gear spins to far - engine not starting. @For all - sorry for my bad language .... When i will have time - i will make video ...

dt502001 Posted March 24, 2013 Share Posted March 24, 2013 Ok I got what hes sayin the sprag clutch isn't catching.Also didn't help that the first link takes you to the elce's not the starter clutch page emilz you need to fix all parts in nr10 ...12roller and 13spring are free wheeling around and not "ramping out" to lock up part 10 to the crank. Week springs worn rollers are your problem,or worse the crank is worn down. Link to comment Share on other sites More sharing options...

dt502001 Posted March 24, 2013 Share Posted March 24, 2013 Ok you must have missed this Ok I got what hes sayin the sprag clutch isn't catching.Also didn't help that the first link takes you to the elce's not the starter clutch page emilz you need to fix all parts in nr10 ...12roller and 13spring are free wheeling around and not "ramping out" to lock up part 10 to the crank. Week springs worn rollers are your problem,or worse the crank is worn down. As far as putting a kick start on your inner case would have to be machined/cast from the factory to fit in the kick starter and you would need an new outer case with the hole in it and the kick assembly.Wouldn't it be easier to fix the starter clutch ,it will definatly be cheaper. The springs and rollers won't cost more than 20 bucks. Link to comment Share on other sites More sharing options...
emilz23 Posted March 24, 2013 Author Share Posted March 24, 2013 And inside in case are spot behind cluch special for something (i think for kickstarter). .edit - i think i can repair the starter and put in kickstarter - for reason if starter "end" again.

dt502001 Posted March 24, 2013 Share Posted March 24, 2013 Yep you can put in the kick then,ididn't know the case was already set up for it, you should have posted the pict first. The larger gear is suposed to spin after the started button is released,it's only "locked" to the crank during starting via the roller's #13,and wont lock up once the eng is running.

dt502001 Posted March 24, 2013 Share Posted March 24, 2013 Opps it's early morning and I just got up.... the sprage clutch contacts the back of the stator (magnet as you call it).. not the crank,so you will need a puller to get it off the crank.

emilz23 Posted March 29, 2013 Author Share Posted March 29, 2013 So, from whitch "DT" models the kick starter mechanism is compitable to my model?

emilz23 Posted March 31, 2013 Author Share Posted March 31, 2013 And - as i looked at yamaha kickstarters, then yamaha yz 125 kinckstarter is the same as yamaha dt 125. Im i right? Please someone can give me sizes of mechanism of yamaha dt 125 04-08? Link to comment Share on other sites More sharing options...
Sacha Posted March 31, 2013 Share Posted March 31, 2013 As DT502001 said "check the part # for both bikes if it's the same part# then yes." To do that, you can look at the online schematics on sites like powersportsplus.com for the different years/models and see if the part numbers are the same.

emilz23 Posted March 31, 2013 Author Share Posted March 31, 2013 I have no # on my bike, because i have not got such a part, because it orginaly is not coming with my bike. So ... Peoples at yamaha.com have such a information about this question of my? Link to comment Share on other sites More sharing options...
Sacha Posted March 31, 2013 Share Posted March 31, 2013 Hmm... I see what you mean. I can't find a schematic for the 2006 dt125x that shows the kickstart mechanism. I would call the Yamaha dealer and see if they know. Link to comment Share on other sites More sharing options...
