so im susposed to go riding tomorrow and started getting the bike all ready well it wont start, pulled the plug have good compression and good spark i even used small amount of quick start in the carb and nothing then quick start in the spark plug hole and nothing if it has spark and quick start even without fuel it should start for a cople seconds but absoutely nothing.....one idea is its too cold? my brother said 2 stroke's do not like the cold? im clueledd i just rode it a few days ago with no problems

 

Did you try to push start it? Was the plug wet/covered in gas when you pulled it out?

 

tie a rope to the bars and have some on pull you a bit. i bet it fires up.

 

...and that would turn out something like this...

im kind of in the same boat bro. hopefully i figure it out today and will be able to give you some ideas.

 

Is it getting spark? Might be the coil.

 

spark plugs have kicked my ass before on two strokes. if you have fuel and compression that leaves spark as the problem. i bet that spark plug is grounding out. pull the spark plug and plug it into the coil wire. touch the spark plug threads to the engine and kick start it. most likely you will see the spark jump from the threads and not the electrode.

Ive had that happen. I learned real quick that with 2 strokes almost every problem can be solved by a new plug lol

 

think i got it, pulle dthe head and dam! about 4mm wide and from top to bottom theres a gouge in the cylinder wall. the pistin where the ring meets was messed up so seems i need a new top end which sucks because i just spent 140 on new piston/ring/gaskets, now i need to either bore it or get a stock replacement used. thinking either the gas/oil was wrong but it ran fine for a whole day with no problems or it overheated on me on a trail when i was going slow? or i installe dit wrong somehow

 

who knows man, you coulda put the piston in backwards for all you know. this stuff is touchy. since its a 125 id just bore it bro. otherwise your going to need a new sleeve and that shit gets pricey. did you atleast coat the cylinder walls with 2 stroke oil when you installed it? did you heat cycle it in the drive way 2 or 3 times bro? i bet you didnt break in that top end right. its a process....lmk when you got the parts for it again i'll help you out.
