Dzsini Posted July 6, 2010 Share Posted July 6, 2010 Hi! I bought a Yamaha SR125, and it was standing for a long time so I decided to change the oil. Can someone please tell me what is the size of the crush washer. I don`t want to drain it and leave it like that till I can find the right one. Thanks for the help.

root Posted July 7, 2010 Share Posted July 7, 2010 I dont think mine had a washer can't remember ? but if so you can always drain the oil & mormaly reuse washer a few times & take note of it for next time . Link to comment Share on other sites More sharing options...
Paulwhite Posted July 7, 2010 Share Posted July 7, 2010 not sure about the crush washer but you should b able to re-use it if not check out wemoto they have a big parts list so might b lucky. and i hope your doing a little more than just changing the oil if its been stood a while, youl probably need to either clean or replace the oil and air filter, get new spark plugs, and might need a new battery, then you will have a better chance of getting it started up 1st time Link to comment Share on other sites More sharing options...
Dzsini Posted July 7, 2010 Author Share Posted July 7, 2010 Thanks for the reply guys. I think the spark plug is changed I`m not sure about the battery, but anyway It starts up for the first push on the button. Yeah I`ll clean the parts mentioned I`m not sure how exactly but I got a manual in my hands so I think I can do it It`s like LEGO for adults Link to comment Share on other sites More sharing options...

Paulwhite Posted July 7, 2010 Share Posted July 7, 2010 lmfao but yeah (cough) you can clean the air filter in warm soapy water then dry it out for a couple of days then soak it in somethin .....think its either oil or fuel... im not sure on that one lol but ur probably better off buying a new oil filter. if it starts 1st time then ur battery should b fine so good luck m8 Link to comment Share on other sites More sharing options...
Dzsini Posted July 7, 2010 Author Share Posted July 7, 2010 Hmm I found the oil filter in the manual looks OK, but I`m confused with the air filter. At this link My link the air filter is round, but in the manual its drawn like a flat thing like a srceen. Edit: Maybe it has something to do with the year my little one is a 2002 one.

root Posted July 8, 2010 Share Posted July 8, 2010 Ignore that air filter link it is not what you want , the air filter is just a square sponge type you'll find it behind one of the side pannels if its ok & no holes or damage just wash out with petrol/ white spirit or similar let dry soak in fresh oil & squeeze out the excess to leave damp the air filters if you need one are £6 on ebay that you will prob have to cut to size .

Dzsini Posted July 12, 2010 Author Share Posted July 12, 2010 I cleaned the air filter, after I wanted to start up the engine before the oil change, but failed to start Last week is started flawlesly, don`t know what to do Link to comment Share on other sites More sharing options...
root Posted July 12, 2010 Share Posted July 12, 2010 Check the plug isn't soaked prob will be after turning over dry refit & try without choke out, w hen you cleaned air filter did you squeeze the excess oil out to leave just damp ? if its dripping with oil it will restrict the air intake ....

Dzsini Posted July 12, 2010 Author Share Posted July 12, 2010 I used little amount of oil, and squeezed well. When I push the starter it makes a weird noise but nothing happens. We pushed in the bike went well after stoping tried to warm up a little more just pulling the gas but stoped sudenly. Link to comment Share on other sites More sharing options...
root Posted July 12, 2010 Share Posted July 12, 2010 Take a deap breath & start a fresh Charge battery, check terminals are clean & tight ,if its low it will not run properly or turn the engine over fast enough to start. clean & gap plug or better still renew it & gap the new one , plugs are too cheap to skimp this. spray plug cap & lead/coil & starter motor ect with wd40. if it turns over ok but still wont start after a few tries, dont drain the battery take the plug out & check for a good spark out of the motor, rest the plug nose against the cylinder head you should get fat blue sparks & while plug is out see if you are getting fuel to the plug by putting finger in the plug hole & turn over .this will also give you a rough idea of the compression status . EDIT.. take care when checking for spark I normaly just hold suppressor cap but if your not used to being zapped use some thing to insulate you , rubber gloves to hold by the cap or insulated grips to hold plug on the hexagonal part of plug.

Dzsini Posted July 12, 2010 Author Share Posted July 12, 2010 Thanks for the advice, I have to purchase some tools like the battery charger, and the plug remover. Zapped myself few times playing with electricity when I was a kid so I think I`m used to it Edit: Can you tell me please which size of plug removal do I need, found some but not sure about the size.

root Posted July 13, 2010 Share Posted July 13, 2010 Noooooooh this is not toy electricity & can realy hurt or worse its not just 12volt dc its like old bills tazer so be careful & use something between you & the plug,The plug spanner/socket is 18mm ok.

Dzsini Posted July 17, 2010 Author Share Posted July 17, 2010 Good news she is starting up fine. Charged the battery before everything else and looks like solved the problem. Later on I can replace the spark plug just to be sure, got a new one only need a wrench for it. Changed the oil as well, she has a much nicer sound now. Only one problems remains for now, the neutral rpm is to low, she just stops if you leave the engine runing by itself. Where can I adjust that? Thank you^^ Link to comment Share on other sites More sharing options...
root Posted July 17, 2010 Share Posted July 17, 2010 On the side of the carb is the idle adjust screw start engine & give it a litle gas you dont have to rev its nuts off hold the throttle open a little turn the screw in 1 turn should do , then release the throttle & let it settle if its running too fast back it out a little at a time letting it settle each time you turn it until you get it how you want .
