Question about 2005 Yamaha DT 125 RE

1 Answer

My Malaguti rally runner (DT125) wont run right when hot.

Hi, have been tinkering with the DT125 copy and cant get her running right. She runs lovely when cold but as soon as she is hot she bogs down and behaves a bit like she is not getting fuel or the coil is going, Juddery, looses power then it suddenly comes back again then fades away. Have tested the coil and it shows the proper resistence values and have taken the carb to pieces and serviced it, tuned the floats etc. Also cleaned the petrol tank and looked in the air filter. HELP!

Fuel pump not working unless i hot wire it still wont fire 1995 4 runner


Most likely your fuel pump needs to be replaced. If, when you turn the key to the run position, you can't hear it humming for 3 to 5 seconds, it is likely burnt out. Best way is to take the fuel cap off, and have someone stand at the cap and listen. You will need to drop the fuel tank to replace the pump. ( PS: Never use starting fluid on a gas engine. For one thing, it can cause an explosion, and for another thing if it backfires you can blow your intake gaskets etc out)

Hi i wanted to know if there is a 64bit version of your 'Urban Runner'- im a big fan but my computer doesnt want to run the game :(


Try running it in compatibility mode for windows xp (right click on the exe and click properties, then click the compatibility tab, click run in compatability mode, then try xp or vista.) Hopefully that works out for you.

1975 dodge 440 runs great but after tinkering with it it wont sta


I guess it runs if you jump it at the starter??? if so, power comes from the ign switch to the trans (neutral start switch, then to the Starter relay, then to the starter. so ck all that wiring an dsee if maybe you knocked something loose, or try to start it in neutral.
