Start with a fresh spark plug. Part of the spark may be traveling to ground via the carbon deposit on the ceramic electrode insulator. Drain the carb; condensation in the gas tank may have built up in the carb float bowl. Engines don't run well with water as fuel. While servicing the bike, clean the air filter and lube the cables.

Yes, that would sound about rite the xl125 r along with all the single hondas are pron to chain noise, easy fix, remove alternator l/ h cover, also timeing cover on cylinder head, mark plate and case with screwdriver for exact replacment, undo 10 mm bolt in end of camshaft and remove the atu unit take care not to loose the locating pin from the camshaftRemove the pin if loose, undo the 2cover bolts and remove the cam cover, locate the timeing mark on the cam wheel and turn the engine until the mark on the wheel aligns with the mark on the case at about 12 oclock, then check the position of the lower pully and mark this, undo the top wheel bolts securing it to the camshaft, gently pull the wheel of the cam slightly and then hook the chain off the wheel, the cam wheel will now pass through the case opening,the cam chain will now come off the lower wheel, and can be pulled up and out over the end of the camshaft, and replacment would be in reverse order, checking alignment of all previously noted marks and security of all fixings before rotating the engine with a spanner and check it completes a full 360 degres before atempting to use the kickstart, the tensioner is addjusted by removing the top nut from the tensioner located on top of the crankcase lh side at the rear of the cylinder, then undo the 14 mm tensioner bolt, you could try first off screwing a 4mm screw into the tensioner, where the 10 mm bolt is removed, undoing the 14mm and pulling up on the screw with a pliers while tightening the 14mm locking device, as the tensioner is automatic this would be a manual addjustment and may remove the exsess slack

You may find the jets in the carb have gone fluffy due to corrosion. That will stop the petrol from atomizing correctly. It may well improve with running as the petrol/air mixture cleans the jets.
Hope this helps.

on the back of the cylinder head you've got two 10mm nuts/bolt heads, with the engine running SLIGHTLY loosen these bolts and then tighten them back up and the excess chain noise should be gone.

Hope this helps

No XL 125R is shown but the XL125S-A uses the same coil.

this sounds like your starter motor turns but slip or does not engage the motor properly .
you may also have a bad connection which the relay may be faulty and cuts the poiwer to the HT .
I would say the electrics have to be looked at first and make sure you do have a spark while using the starter motor .
If not , you have a electric problem like a relay that does not work properly

make sure the clutch cable is properly adjusted, next thing would be to check if your clutch itself is in good condition and adjusted. to test, pull clutch lever in (with bike off) place it in gear, bike should move freely when pushed forward.. if that is all well and doesnt work good, you need transmision repairs,shifting forks probably bent.

hi m8,, usually if the cdi is playing up u wont have a spark at all,, has the carb been cleaned out, ,,id look at the 1st,, ,clean the jet out ,,and any brown residue,, pull off the plug cap from the spark plug,, ,, then unscrew the cap and just snip a little bit of the ht wire off,, so u see a copper lookin bit of wire pokin out the middle of the black ht wire,, then screw the cap back on,, try this 1st m8,,

It sounds like you must have a relatively old bike to be dealing with breaker points. If you are sure your points are OK, I would suspect the condenser next. They are relatively inexpensive (if still available for your bike) and usually require only a mounting screw and a connecting screw to replace. Next, check the ignition coil and the high tension wire to your spark plug. Of course, I'm assuming that you are working with a good spark plug.

sounds like a blocked or restricted idle jet

their could be a lot of problems plugs plug wires and your carburator

Steve. While I would never tell anyone to bypass a safety switch. You can usually pull it off and wrap it in electrical tape. That way you are not riding while trying to hold it down. Sometimes you can jump the wires across each other to bypass the switch too. But it depends if the switch is a closed or open switch.
