My son just boufght a old 1990 Honda 300 fourtrax which is leaking on oil from the side case, by your left foot, that goes to the front drive.
Does anyone know where I could find an on-line PDF for the Honda 300 fourtrax, downloadable ?

 

youll never find one, i looked all over the internet, your better off buying one from your local dealer.

 

I did some looking for you and found if you go to AMAZON.COM and type in the book ISBN number of 0-89287-640-9 (just the number) you will get a search result for it. You can get it new for $30.....or if you look over at the right side of the screen you can buy the book for $21 used. The book is by Clymer and my understanding its a really good book. As of now, I cant find any type of manual online available for download. Hope this helps.

 

i got the clymer manual and it is really good, it shows you everything about the machine from simple maintenance to overhauling the quad, but like i said earlyer you will not find a downloadable version on the internet. trust me i looked every were.

 

I saw TRX300 PDF shop manuals on ebay ...
