Dt125

Hi guys, I've recently replaced the carburettor on my bike. The replacement carburettor I fitted was from a Yamaha TZR125 which, in essence, has the same overall engine layout and design as the DT125R. The carburettor I fitted was a Mikuni VM26SS which is what was already fitted to the DT125R before. The problem now is that when I try to kick start it, it starts for about three seconds before cutting out. When I kick start it, I can smell the fuel strongly so that means that the fuel is getting to the cylinder but isn't igniting properly. The spark plug hasn't been changed in at least a year so I was wondering if this could be the solution. If I replace the spark plug …

Yeah I've been looking at graphics kits for my 2013 YZ250F special edition (white) but I'm not sure if blue graphics kits will look odd or not on the white plastics. Any thoughts or suggestions with this one guys? Thanks. - Jake

So I recently bought my new YZ250F and I was wondering if it was normal for fuel to be leaking out of carb overflow after riding and with the fuel turned off, for example: After riding turning the bike off and the fuel off, loading onto trailer and driving home with fuel leaking out of overflow onto the trailer. Also I found it strange that when I turn off the fuel and lean the bike over fuel rushes out the overflow. I do understand that when the fuel is leaned over that the carb float cannot function properly filling the bowl and overflowing but I don't see why it would be happening if I had my fuel turned off in the first place.

Hi, By accident I threw away the oil line that attaches just above the oil filter cover and runs up to the back of the engine just below the head. I have a photo but haven't figured out how to attach yet. By my description, does anyone know what this part is called and where I can buy one?

Hi Guys Firstly, hello and i'm here to stay! I've acquired a Yamaha XT125 X for my first bike, and cant wait to ride it after i take my CBT on Sunday. I was just wondering how you remove the seat to gain access to the battery, i need to disconnect it as my speedo is set to Enduro mode but mine is the motard version and i hear that there are issues with the speedo being out by as much as 10-15mph because its on the wrong setting! I don't want to go through a speed camera at what i think is 30 according to the speedo and be going 40! Much appreciated Duke

Hi Guys. Having real problems getting her to run properly. SYMPTOM: When riding in 5th at about 60mph, If I come off the power the bike wont start to accelerate again until the speed drops to about 35mph. (Feels like she's bogging down!) Does the same thing in 4th aswell. + Had full top end rebuild. (Ran fine after rebuild) + Carb float valve replaced + Jets flushed and cleaned + Tank cleaned out and flushed + Adjusted mixture screw several times - no luck + Running slightly smaller jet at the moment - could this be source of problem? Any help really appreciated.

hey all from others experience is it the yamalube oil pumps that tick loudly at idle. it almost sounds like a cracked hydraulic lifter in a car? or is that bad rod bearings? I can post a video, but if others find the oil pumps noisy then I wont worry

I have the cylinder off. How to I remove the piston without removing the connecting rod? Do I need a special tool? Who sells it ?

Hello, I'm new to the forum as I recently purchased a Yamaha TT600R which I have now found out has a later engine fitted, this one with the electric start, all in all I'm very pleased with the bike, got the Ohlins rear shock etc, it was purchased to do a little green lane riding. Anyway, I've managed to get general service parts and fork oil seals without to much of a problem but I need a new gear lever, the Yamaha listed one is ridiculously expensive for such an old bike and I wondered if anyone could tell me if an XT600 gear lever would fit or if you know a supplier that makes pattern ones cheaper ? I look forward to hearing from you soon and getting lots of advice a…

Hi all, first post so go easy. Passed my CBT and then went out and bought myself a 2002 DT125r, Electric start only covered 2000km. As you can imagine as i had just passed my CBT i was on it every day for about 3 weeks, it worked flawlessly. I noted that the front head light had stopped working, so got myself another lamp and changed it. turned the key and it didn't work, so tried starting it, Nothing. The Engine will turn over on the button, with good compression. Have tried cleaning the spark plug(iridium) and tried a new standard plug, with no effect. Fresh fuel, without the air filter, new coil, still to no avail. The wiring seems fine all plugs are clean and…

Just wondering what you guys are using for the XT350. I guess 50/50 or so. Been using Kenda 270's front and rear. Any other suggestions? Looking for cheap long lasting tires with some bite. Really haven't had any problems with the Kenda's just wondering if there is anything any better? thanks
