Still got problems with sr125

Comment by kitten_art, posted on Nov 17, 2008Thankyou
Bike still running rough even though we have cleaned carb, changed air filter, checked plug, lead, fuel line. Wont tick over nicely. Throttle cable seems to be sticking, oiled it, but still not returning to tick over when revved. Oiled the carb throttle slide.
Sounds very tappity, but local bike shop said that was nothing to worry about.
Helllllp!

    Just so you know, you were spot on with the valve comment, the adjuster screw was actually making the tappity noise and the valve will need replacing very soon. Have filed down the adjuster screw and it is a lot better for now.

    Thankyou ever so much for your help.

    That screw adjusts the fuel and air mixture does it not? I assume that is the one you are referring to. That has been adjusted to correct position. Bike running ok....but will need a new valve in the fairly near future. In hindsight, there were two problems, one was the tappity noise, which was found to be the valve adjuster screw, which we have filed down. Then the cutting out and lumpy running was due to the mixture screw being incorrectly set.

    Thankyou for the suggestion though.

I would replace your cable and you need to check your valve clearance.

you say there is a noise on the valve , do you mean the inlet and exhaust valves ? if they are making a jingelly tappy noise then they do need adjusting ! does 1st to third gears rev to near enough max revs in each one or do the faulter and miss ? if miss then have the carb and fuel tank cleaned as well as the adjustment of valves ! exhaust could be choked up also if you only do town runs also , may need decoke of exhaust port and exhaust system !

Full disassemble of carbs is needed. Thorough cleaning on jets and airways, vacuum and pilot screw adjustment must be done too.
Check the spark plugs for lean mixture indication and replace them if necessary.

Sr125,tune off 4star on to premium


If I understand you this bike has not run in a long time?
If so the carburetor would be gummed up with
dried up fuel. Clean the carb and internal jets
thoroughly, check the fuel tap and lines
and use fresh fuel. It will not run well if the
carb is dirty from old fuel.
Once clean the carb will respond to screw settings.
Turn for the smoothest idle.
Timing may not be an issue if it has electronic ignition.
It is not adjustable on Yamahas.

Can you put fuel cleaner in your gas tank? my bike runs fine then it stalls and sometimes it won't start. I just bought the bike and the owner had it setting for 2 years in his garage can it be bad gas?


Hello shawn...Yes indeed gasoline can degrade over time. That can lead to a number of problems, ranging from hard starting, to rough running, to no starting at all...If your bike was stored for 2 years the gasoline in it has degraded beyond use. Even if the gas was treated with stabiliser before it was stored...it will still degrade in 10-12 months, if not sooner. I'm suprised your bike will even start. I suggest you drain ALL the gas out of the tank, Rinse and refill with fresh gas, drain your carbs as well...the stale gas has most likely clogged the pilot jets, draining the carb bowls will help.
Go to your parts store and buy a can of "Seafoam" pour 1/2 of it in with your fresh gas..use the other 1/2 on your next tank of gas.
Replace fuel filter after 1st tank, the seafoam will dislodge any debris that was in the fuel tank. It will also clean the combustion chambers and carb jets. Check your carb boots for any cracks or detoration that would cause a vacuum leak. Replace your spark plugs. If your bike is still running rough after this, then the carbs will need to be removed and cleaned and/or rejetted.
Good luck..i hope this helps, please rate me a fixya.

1995 Suzuki DR650 still running rough


sounds to me like your jets are running rough, wich makes you loose power and make the bike run like sh*t, so simple re-jet it (65-75 dollars) and it will be running like a charm again
