i have a honda 125, at quarter throttle it boggs out, also i only have two gears, after that 3rd and up it grinds it still moves but it grinds

 

grindin...ouch..that doesnt sound to good...gonna half to split the crankcase..and u may wanna clean out the carb for the bogging problem

 

yea i forgot to say, i did clean the carb, what about a dirty jet? wait .... do three wheelers have jets? actually when i had it it ran like a charm but, i let my step brother borrow it he messed it all up, also where could i get new gears on the internet if it is the gears...

 

Yes, lol, they do in fact have jets....a main and a pilot jet.....its quite possible its a dirty jet...for parts in your trannmission go to Here and select the year according to your bike, becuase u havent posted what year it is...also for the carb, he could have adjusted the air/fuel mixture, which i believe should be on the front of the carb, and it shold be 2-3 turns out i think..dont quote me on that tho...

Good luck w/ that

hey i went to that site ...but they dont have a atc 125 theres 110,185,185s thats it...

 

Those 125 trannies are crap. I bet I have rebuilt 20 of them. You are going to have to check with some ATV/ATC salvage yards. Any 4 wheeler mag will have at least 10 ads in it for them.

 

well i looked at the site your right...i found that they had parts for a 1984 honda 125m...im not sure what year yours is..younger/older....is the parts are interchangable or not but, go back to my other link and try putting in 1984 for the model year and u'' get some 125m stuff
