Clutch dragging / slipping? you need to have free play in the cable the lever should not be tight up against lever holder there should be a loose gap.
How do you change water pump seal 98 rm 125 !!???
It should be just that, a leaking seal, gasket. The water pump is external on that bike and doesn't go anywhere but the cooling dept.It doesn't get mixed with oil or anything. Take off the pump itself and replace the gasket. I think that should do it, unless it is the pump itself leaking.

That is an ebay ad. Just in case. Hope this helps.
I was riding bike stoped has compression and spark
fuel, fire, and time.fuel in tank doesn't mean its making it to the piston,(dirty carb orfaces,or loose vacuum lines could stop fuel flow) fire needs to be blue not weak red or orange,(weak battery or blown fuse, low oil cut off) and timing must be still set within tolerance.
How tighten a chain
well first get the bike up on a stand or set it on a milk crate. Loosen up main axle nuts you may need another wrench on the other side to back it up. loosen any small chain adjustment nuts. pull the chain as far back as it can go all the time looking a the chain sag..you want to keep about 5/8 to 1 inch play...lock just the axle nuts down snug...now spin the tire to see that all parts of the chain maintain this amount of sag. if its too tight in one area, you have a "stretched chain", and this will now be the focal point for tightening up the chain...this tighter part must have "some" slack in it...id say give it about 1/2 inch...now tighten up the chain adjustment nuts finger tight and look at your rear sprocket and make sure it lines up perfectly straight on with the counter shaft sprocket up front. Once this is aligned, tighten the smaller nuts snug, then proceed to torque down lightly maybe 10- 20 ftlbs. now spin the tire to check your slack in the chain did it move on you? Then you have to tighten or loosen the chain adjustment nuts a little more in or out till you get it right so it can move into the correct position. Once you got it right torque down on the main axle nuts 50-60ft lbs. Now tighten evenly each chain nut with the same ammount of turns to each....tighten the last nut down hard onto the first so they wont vibrate off. Now you should lube the chain..and your ready to go. after a while of hard riding recheck everything just to make sure shes secure! Can i get a very helpful on this. thanks!

? whats ur question ???????
I have engine coolent leaking into my clutch oil
Have you recently had the engine case apart? [even if not], ..check your rubber O-rings [seals]. These o-rings, located inbetween the clutch case cover and the motor itself,...if damaged, allow coolant to seep into the oil.
FUEL RATIO
For motocross racing..50:1 gas:oil mix. For trail riding and sand pits,..try 40:1.
What kind of oil does my 2003 rm 125 need
For the gas tank= 2-stroke motor oil mixed at 32:1 *stock mixing ratio* [that's 32-parts gas to 1-part oil]. **[I personally use a 40:1 mixture for trail riding,..and 50:1 mixture for racing at the local MX track].
There is an adjustment dial on the cylinder by the
Exhaust power valve, [1/2 turn out is stock], 3/4 turn gives you a longer lived low-end for corner shots and that extra uummph! of torgue to blast out in a holeshot.[so yes,..it delays closing the valves]. Experiment to see where your "power" tastes lie. *technology...you just gotta love it !!
I have a 1990 suzuki rm 125 starts first kick, but
I'd start by thoroughly cleaning out your carb.,...check/replace the main jet with a leaner, [higher #], jet...change/clean pilot jet also,..spray carb cleaner in all holes and blow out w/compressed air. Re-check your float height and/or any damage to the float pin+tangs etc. Maybe try a 50:1 gas:oil mixture. Perform a leakdown test,..air will cause boggs as well. *[p.s.; does bike blow oil out exhaust?].
