Question about 2004 Suzuki DR-Z 125
Okay theres a couple possable things that can cause this .... carbon on the valves, ran hard,not frequent oil changes, low on oil, cheap oil, spark plugg is too long , too much oil somtimes causes this,crank case breather plugged,it all depends on the way it was treated in the past or the present
i change my oil about every 15-20 hours keeps debre down and less friction on engine,remember this is not water cooled! so use the best 10-40 oil or atleast good known oil and run some seafoam through the gas,it will take that carbon off . and if you dont have a inline fuel filter u should get one they really save carbs and there only $3.00 at oreily! hope this helps <walker>

This is nomal for a DRZ 125 because of the short piston skirt. You get much the same annoying sound on the 250/400's also, don't stress, thats just how it is.
