AndrewElvisFan Posted January 17, 2014 Author Share Posted January 17, 2014 Just tried it now and wouldn't start. The battery only had half hour charge and is now not turning over quick enough. I'm too cold, wet and hungry to carry on now so best clean the sink! I'll jump it in the morning from the car with a little prayer :/ Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 17, 2014 Author Share Posted January 17, 2014 Just what the wife"s gonna do , when she see"s the sink,,, Top tip here - Bar Keepers Friend. 5 minutes to bring the sink up to sparkly like new shine.

AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 Almost got away with it but she smelled the carb cleaner and I left the oil can on the side lol Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 On a lesser note although I did get her running this morning and ticking over, when I went to check the pilot screw,which is set to 2 turns out, I thought in my novicity (is that a word?) that final setting needed it turning quarter of a turn either way and seeing if the idle speed altered? Should I be concerned that even 3/4 turn either way made very little difference? Could this be the reason for her not firing up? The spark plug is showing sooty deposits - too rich or just that I haven't actually ridden her and been idling fast? She does now bump on 2nd or 3rd attempt in 2nd. occasionally I have noticed the starter motor doesn't kick in and I hear the relay clicking on. TDC is actually TDC according to the marker btw so not suspecting timing. Working through the list a methodically as I can. Is the CDI the next to cross off? Is there any way of checking it or is it a case of stick a new one on and see?Sorry for being long winded, just trying to pre empt any questions and give as much info as I can!

AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 She was pleasantly surprised at how clean the sink was though. And by pleasantly surprised I mean shocked! Link to comment Share on other sites More sharing options...
jimmy Posted January 18, 2014 Share Posted January 18, 2014 As far as I am aware, the only way to check is by replacement. Anyone near you have an sr or If there are any breakers yards near you, they may allow you to try before you buy, but that'll depend on hope good a mood they're in If you're having to buy one, remember there was a changeover around 2002 I think and the wiring connections changed so you'll need to make sure its the correct one Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 Cheers Jimmy. I've cleaned the plug back up now so straight after lunch I'll try that before sourcing a new CDI. No rush today as wife at work again and can't leave the kids - even tied up its frowned upon! Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 18, 2014 Moderator Share Posted January 18, 2014 No you cannot check the cdi without specialist equipment, for the home mechanic yamaha suggest you check everything else first. They give a list of specifications for the resistance values of the magneto and HT coils and youre supposed to check these are within spec before laying out £££'s on cdi's Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 Ok. Need to borrow one then - I leant mine out ages ago and can't even remember who to! I know someone who'll have one but has to wait til tomorrow now. Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 18, 2014 Moderator Share Posted January 18, 2014 study your manual, look for the specs and be clear how you're going to take measurements I'd get the battery charged up too and if it's not in good nick that may or may not make a difference...It doesnt on my DT, that will run without a battery fitted because it's a magneto ignition Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 Charging the battery ATM by way of leaving it running. When I get hold of a multimeter I'll check whether its accepting a proper charge or not. Cheers mate Link to comment Share on other sites More sharing options...
blackhat250 Posted January 18, 2014 Share Posted January 18, 2014 Yeh "CDI"s very rarely go wrong, a new battery will clear up your starting issues,, , the air[ pilot ] screw , it should alter the slow running when screwed fully home, [ engine should stummble] then screw out till even running is heard, Link to comment Share on other sites More sharing options...
Moderator Airhead Posted January 18, 2014 Moderator Share Posted January 18, 2014 Yeh "CDI"s very rarely go wrong, a new battery will clear up your starting issues,, , the air[ pilot ] screw , it should alter the slow running when screwed fully home, [ engine should stummble] then screw out till even running is heard, sometimes the pilot screw adjust fuel not air and the result is they work opposite ie...air screw clockwise to richen Fuel screw anti clockwise to richen air mixture scews are often found on the airbox side of the throttle slide and vice versa for fuel mixture screws 1 Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 The screw is on the engine side. When seated in she stumbles and stalls but doesn't seem to make a difference screwing it out from the original settings. I can't remember if I mentioned that yesterday the only way I could keep it running was by having the idle screw almost all the way in so high revs but now she is very happy until I stop the engine!

Moderator Cynic Posted January 18, 2014 Moderator Share Posted January 18, 2014 Sounds about right, you want to try it on the tdr, two of everything. But they are adjusted as one. There are official ways to set them up but ear and experience is best. Be the same with yours, it prob is making a difference your just not sure what your listening to. Why is she not happy when you turn it off. Link to comment Share on other sites More sharing options...
AndrewElvisFan Posted January 18, 2014 Author Share Posted January 18, 2014 She just won't start again without a while heap of grief! Just been searching through old forums re SR125 starting issues........ seems a few on here lol. It appears charging the battery by idling is not best for the engine. Also seems to be a lot of CDI issues that have been brought up. I haven't checked the valves yet so that's next on my list! I turned my hearing aid right up and couldn't hear a difference in engine tone until 1/4 turn away from all the way in lol. Link to comment Share on other sites More sharing options...
