clean threads apply a little loctight and just do it up tight

replace it

Should be an adjustment nut on the back of the brake arm.

That is about right. 125 cc four stroke engines do not make enough power to exceed that speed.

The linkage lever on the closest to the engine case is on upside down.

Look under bike on kickstand.If there is a switch it will be right on the bracket which holds kickstand to bike.unplug wire and clean,somtimes is just dirt on contacts that causes the switch not to make up.use some wd 40 to clean and if there is any water in switch this will displace water and make switch operational.Worst case senario jump out switch and see if bike starts,If so replace switch and you good to go Good Luck.

CHAIN TENSION?? ABOUT 3 FINGERS FROM SWINGARM. SHOULD BE VERY SNUG

remove the fitting from the axle, use either a Brake rotor cleaner to clean the brake assembly then put some axle gear on all moving parts. refit and see the changes.

Take the carburetor out and clean it. Often the dirt is too small to see.

Sounds like it's starving for fuel. check for dirt in carburettor main jet,

The original silencer doesn´t let the engine breath, so a better silencer provides lots of more fun. Check this out: http://www.mg-sport.com/english/crd_e_22.htm You can also put a bit larger main jet in the carburator. Motorcycle tuning spesialists can also fix the cylinder head, and install more opening camshaft and harder valve springs(but is +10-20km/h at max speed so needed?).

3M protective film works really well I have it and highly recommend it.

Have you check the fuel filter? Have you checked the in tank screen on the petcock?

Running hot? Isnt this an air cooled engine? Have you drained the old fuel and put in fresh fuel? The black on the plug tells me its running rich,and that the carb will probably need to come off and be cleaned out. Also,add a inline fuel filter if at all possible.

Probably water in the carb. Condensation in the gas tank can make it's way into the carb float bowl. When it builds up enough water the carb sucks it into the engine. Bikes don't run well on water. Drain the float bowl.

its pretty simple on that bike-just the same as old carb--u can get carbs rebuilt and cleaned-look in classic bike mags

vent lines ? float stuck/ bad gas fuel mixure/ spark plug/ coil weak
