my friends has a yz 125 it smokes like crazy even when warmed up it will not idle or hit powerband im thinking just to do a new top end but not sure if theres anything else to consider

 

Thats sounds right, I would also clean the carb up too and check the reeds for cracks since you will have the jug off anyway. Is this something that just started or was it brought on by changing components or anything? But I bet a fresh hone, new rings and piston will solve it.

Back when I raced motocross I had to do a top end after every race or I lost considerable amounts of power!

 

are you mixing the gas too thick?

 

good call...But then he would be fouling plugs. Are you fouling plugs too? The ratio for this bike is 32:1.

 

Just depends on what type of 2 stroke oil you use. Some say mix at 50.1 Others you can mix at any ratio.

 

Don't know if it's water cooler or not but if it is what about a blown head gasket? I know on Honda's when a crank seal goes it will let tranny oil in the crankcase and it will smoke more than normal.

 

so my nabor whos bike this is im figuring out how clean handed he is i thought considering he work for lincoln tech that he would be atleast some what mechanically inclined well it turns out hes a councler which is good for me hes getting me a scholarship but it turns out hes clueless to evrything with a motor so i cleaned the carb and put 32:1 gas and a spark plug in that bitch and it runs perfect i mean it has no bottom end but i think its cuz im used to riding my rm250 but anyways it turn out he bout oil for 2.5 gallons and he put it in 1 gallon of gas lmao

 

thanks for the replys i hope you got a good chuckle out of this 1

 

yessss score lol
