HI THERE.
I bought some time a go a HONDA FOURTRAX TRX 125 ,1987 ,four stoke; in excellent condition.and have used very little.
i'm going to change all the fluids (engine,transmition)to have everything fresh i will like to know any recomendation for engine oil and transmition fluid, considering that is an old engine.
is syntetic at this stage of age any good?
recomendations please?
regards

 

Synthetic would not be necessary, but wouldnt hurt anything either. Any good brand of 10w40 oil will do a fine job.

 

I'm very thankfull with your information, its very helpfull.
what do you recomend for transmition oil for the honda fourtrax 125 trx ,1987 ?

 

they dont not have seperate oil for the transmission... It shares the engine oil
