Posted June 12, 200915 yr Hi Guys, I have a 96 SR125 which was starting ok a while ago, I haven't started it for 6 months but it has been under cover. I tried starting it the other day but it wouldn't catch. Seems to turnover ok. I've since tried replacing the spark plug but that made no difference, seems to be a strong smell of fuel around the spark plug. Battery seems fine but will put on charge anyway. Not sure what I should try next. Thanks Paul.
June 13, 200915 yr Umm... charge battery, clean and gap the plug, put fresh fuel in (it goes off v quickly). You could try turning up the tickover a bit until you get it going. Tried bumping it in 2nd? Mine prefers a r7 to the rec'd r8 plug - YMMV.

Fuel might be the problem then, how quick does it go off?? Thanks Paul.
June 24, 200915 yr Author Hi guys, Finally got it started last night after charging the battery. Not running very well thou, starts with choke and after a few seconds the revs go crazy. If I put the choke in it cuts out. I think the mixture is wrong as the spark plug is black, can't find my mixture screw thou. Just seems to be a hole where it should be. Thanks Paul.
June 24, 200915 yr Moderator you may find that if you cover the hole where you think the screw is missing with your finger when its revving crazy, the revs will drop right down, this would rather conferm your suspicions.
June 25, 200915 yr Author The screw was there, its a recessed screw. Well I reset it to factory conditions but now it cuts out all of the time. Checked the air filter and that was dripping in oil, have cleaned it with petrol and left to dry out. Paul.

Before putting it back in the housing, soak it in oil then wring it out. This stopped our little 125's problems with the revs.
