Engine smoking

Hi All,

Got some questions. I’ve been looking through some of the old threads to see if I could find some answers but no luck.

I just bought a 95 300 fourtrax and the motor is smoking a fair amount. it runs great idles great. seems to have good power, starts right up.

What I have is some kinda crappy replacement exhaust on it. And there is an oil residue in it. It also has a leak in it.

And a supposed top end job a year or so ago.

I’ve talked to some local guys I know they are telling me I probably need the rings replaced and probably valve seals. They attribute the smoking issue to this as a result of an improper exhaust system on the bike not creating proper back pressure. So an exhaust system as well. None of which I mind doing over all the bike is in really good shape.

But I am looking to get as much feed back on the issue as I can before I go dumping money into it.

Also looking for opinion on if I can drive it in the intern until I can put the money together for a proper top end job on it and exhaust.

Cheers
