I Need help my DR 88' 125 doesnt run very well - Motorcycle-Journal Forums

DR 88' 125 · 06-03-2004, 08:22 PM

Im a kid and dont know much about matenince and repaire, I know how to run and ride my dirtbike that weve had since before I was born in 89 but im pretty sure its a DR 1988 125. I dont know if its an L or not. I can get it started after the 10 times or so but it doesnt idle so i take it out with the choke on and after I rid for a while I slowly ease it off and just keep riding so it doesn't stall. The chain I think needs a link out of it because when I go from slow and start to speed up it jerks forward. The chain has popped off once or maybe twice and I just put it half way on and pushed the bike forward and it rolled all the way back on. It probley needs a tune up and I just know how to ride and start it. I was wonderin whats wrong with it. Or maybe just some advice on how to take care of it or what I could unscrew and clean, "If thats all it needs" to make it run a little better. It doesnt really have allot of miles on it. My dad says a couple hundred or so. Its a four stroke and is yellow and blue and it has four gears. I would appreciate any help you could give me on what to do with it or how I should run it. Thanks

There's a few things you could try to get it running better. It sounds like the chain may need tensioning. There will be an adjuster at the end of the swingarm for this. Tighten it until you can move the chain about 20-25 mm (3/4"-1") up and down. It's always a good idea to clean the air filter regularly. Rinse the filter out in petrol and let it dry. Then soak it in filter oil (clean engine oil will do). Also, have you taken the spark plug out and cleaned it? If the engine oil is black, then you should change that too. I'm not sure if the 125 has on oil filter or not. If it does, take it out and clean it same as the air filter. If it's still running like a pig, the next step would be to take the carb apart and clean it.
Hope this helps.

I have a 1994 Dr 125 and have very recently started experiencing the same problem. My DR does have an oil filter. If youve had this bike for a long time and never changed it i would definetly suggest a new filter. I am hoping to fix mine soon, im gonna tale apart the carbs an stuff. Once ive fixed it ill let you know what needs to be done. Good Luck.
