Hi, Terry usually around 1000 RPM for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere zero $0 you can download another one.

SOURCE: Yamaha TTR 250, Idling Problem

check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam

SOURCE: won't idle steadily

Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)

SOURCE: i have a 1984 XR200R with the dual carb set up

You need to remove the top cap off the carb(s) then lift the slide out of the throat of the carb. You will see a long needle in the center of the slide. Lift the needle out then move the clip on the top of the needle down one notch. Two notches may be needed but start with one. Now re-assemble the carb(s). Doing this will richen the low end fuel mix.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

SOURCE: Yamaha DT 125 1986 - High Revs when idling

There have an air leak between the carb and the cylinder and/or the head and cylinder. Old hard / cracked rubber fittings and O rings are usually the problem. When extra air gets into the system it leans the fuel mix and the high idle is the result. It also means the engine runs hotter. Also, cracked or broken reeds can be a source.

Is the throttle cable adjustment directly on top of the carburetor? 1971 yamaha 250 dt ? Where is idle stop located?


The idle screw should be on the side of the carb, you can't really miss it as there will be a spring on it. The adjustment on top of the carb is for the throttle cable & do not use to adjust the tickover speed of the engine.

1977 - 1979 yamaha dt 175


Hi, Skibsy the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have.

Hi, Stevea623 probably but the real answer to this question is way above my pay grade for this situation, I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Yamaha dt 175, voltage question. When idling, my DT measures 7 volts across the battery terminals. When revved it jumps up to over 13 volts. This is a six volt bike. I know the battery is completely shot....


You need new regulator and new battery.The battery works as a filter as well.If it is in bad condition it does not filter anything and in high rpm the current is very high.
