Check you needle and seed maybe needs replacing and most important is the flot level, I would start by striping the carb cleaning it and checking all the parts and jets inside clean and doing what it needs to do, like reducing petrol flow and the right time something is worn I would also replace the little rubbers if possible get a new carb kit if all else fails.

SOURCE: Fuel leaking from carb vent tube on newly cleaned carburetor

that would be either the float set to high or the needle and seat is missing an o-ring while you had it apart. Should look at getting a carb kit there only approx. 23 bucks and it would save you a lot of grief in the long run.

SOURCE: Carbies willn't set float level,right floods,left sets to low

I don't know if its any help but I've fixed my Honda with similar problem. It turns out I reassembled the rich carbys air cut off valve incorrectly. Have you checked yours? I'm wondering if the cut off valves somehow affect the other parts of the carbys. Mine is running sweet now.

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.

SOURCE: dt 175 having trouble selecting neutral. It seems

Neutral should be between 1st and 2nd. Likely cause could be worn or bent shift forks and/or shhift drum. Both are inside the transmission and will require engine removal and case splitting.

Another less likely, but easier repairable cause could be a damaged or miss aligned shift linkage inside right side cover of engine.

SOURCE: I was given a 1975

There is only one fuel line that goes to the carb. Just get some fuel line and connect it from the gas tank to the carb. The other hose connections on the carb are vent lines, that go up over the top of the carb and the back down the other side and hang down lower than the carb. they vent the carb bowl

Hi I have a 1974 dt 360s that needs a new RH front fork and as the DT 175 runs the same size 21 inch front wheel as the dt 175s does that mean the front forks are interchangeable ? I have only been able to...

no not really,the diameter of the fork tubes are probably different,maybe a dt 400 would be closer,replace them in pairs,dont replace only 1,the spring rate & dampening is different,try junk yards in your area,get a complete front end from a dt 400,it should fit.

Manual yamaha dt 175

Usually caused by either a blocked carbie, improperly operating power valves or fouling spark plugs.

The old DT's were renound for having issues with CDI's too. If the above doesn't solve the issue, I'd check the CDI for signs of melting.

Dt 175 only runs with choke

Hi, Anonymous and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.
4. Float needle and seat sticking.
5. Float level too low.
6. Carburetor bowl vent line clogged/blocked/pinched.
7. Idle adjusting screw set too low.
8. Air/fuel mixture screw set too lean.
9. Idle port, transfer ports, slow air jet clogged.
10. Slow fuel jet clogged.
11. Faulty fuel pump.

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.

15.5 Craftsman riding lawnmower blowing oil/fuel mis out the breather tube/smoking-does this indicate head gadket/valve or piston/ring problem. Need repair manual- any ideas?

Hi, drain and change the oil as it has become contaminated with fuel. This is caused by your carby flooding while stored. Check and clean the needle and float in the carby and make sure it stops fuel flow when you hold the float parallel to the carby body. You can also fit an inline fuel tap to prevent this happening again. Hope this helps, regards Phil.

My 175 yamaha dt is not holding a steady idle

Check function of carby choke and that it is not remaining partially open. The idle air mixture screw should be set at aprox. one and a half turns out. Is the inlet manifold providing a good seal? Check sparkplug gap and give it an emery across the electrode.

1975 yamaha DT 175 it floods when the gas tank

I had the same problem - actually more than one problem:
1) Floats in the carburetor bowl (at the bottom of the carb) are getting stuck. Remove the carb; carefully disassemble the bowl & float assembly (pay attention to gasket orientation and don't lose the needle valve that the float-tab presses on!); use a carb cleaner from AutoZone or similar, and a toothbrush to clean all the parts. If carb is not too dirty, leave the jets and mixture-adjust screws alone (otherwise will have to re-adjust later).

2) Overflow tube is plugged (hence fuel in the cylinder instead of on the ground). Clean both ends of the brass-looking tube from inside and outside the carb bowl. Make sure you can blow through it or it is still plugged. Toothbrush and carb cleaner should do the trick. Replace the short flexible tubing that connects to the overflow on the outside of the bowl - transparent polyurethane tubing is less than $1 per foot at your local ATV/motorcycle shop.

3) Air Vent tube is plugged. Same thing as the Overflow tube but mounted higher up in the carb (not in the bowl). Clean it the same way and replace the flex tubing with another short piece of polyurethane.

4) Make sure the float-tab and needle-valve move smoothly. Mine was catching and getting stuck so I carefully "polished" the face of the tab with 400-grit emery paper, and then made sure to clean the area from grit. Smooth as a hot knife through butter now.

5) Set the float level by CAREFULLY bending the tab that pushes on the needle valve. On my 1981 175MX, float height spec is 21mm when just making contact with the needle. Yours may be different though.

6) Reassemble the carb after making sure all dirt and debris are gone. Use a new bowl gasket or at least put a good gasket-sealer compound on the old gasket. Attach the short lengths of transparent polyurethane tubing to the Overflow and Air Vent. When installing the carb, the Air Vent tube should just be 2" long and point out to the side; the Overflow tube should route through the frame near the swing-arm and point down to the ground.

7) MAKE SURE the Oil Feed tube coming from the AutoLube oil pump is connected to the carb (brass-looking fitting toward the cylinder-end). I replaced mine with transparent polyurethane tubing (different size than the Air Vent and Overflow), so now I can see that oil is being presented to the carb!

8) If the carb was nasty-dirty, you may need a new air filter. Mine was disintegrating. I recommend also putting an in-line fuel filter between the petcock and the carb, again using short lengths of TRANSPARENT polyurethane tubing (so you can see that fuel is flowing). You may also need to adjust & prime the AutoLube oil pump.

I highly recommend getting a Clymer manual (check eBay) which shows all these procedures and gives you the right specs for float height, etc. based on your model / year.

Have a 1974 Dt 175 need help tuning

Hi there and welcome to fixya!

Here are some tips that may help:

1. Make sure plugs are clean and you're using good fuel quality. (tank should be clean of water moisture).

2. Turn the air-fuel mixture 2.5 turns out. This is assuming you haven't replaced the stock jet size. If you have increased the jets. Start at 1.5 turns out, if air filter is clean and free flow, you may use 1 turn out. Turn out or inward to make minor adjustment.
Usually experimenting with the air and fuel mixture would do the trick.

Let me know if this helps.

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.
