Just picked up a 02 yamaha warrior and the thing runs fine, but it smokes a lot... its like a 2 stroke smoking a cigar.... anyway i was wondering what all you guys think it needs. top end, bottom end, or both. also how much would a shop usually cost to rebuild an engine this size 350. thanks just an estimate im gonna call later just dunno what to ask for.

that is a video of it running it starts right up.. it is idling high because i had the choke on. i didnt want to run it long because i didnt want to harm it anymore any help is apprieciated

 

Is it smoking white?

 

yea, it smells like straight up oil... also if you run ur finger in the exhaust ur finger gets a coating of black oil...

 

If you look at the smoke closely and it has a blue accent sort of, then its the rings. My warrior smoked worse than yours, but mines is getting rebuilt right now. My problem was that the rings were gone, and the valves werent seating right. Im getting a topend rebuild, and they can run anywhere from about 600-1200+, depending on how many problems there are.

 

Yea you can go that route and not really know until they are all done how much they are going to charge you or you can do like I did. When I bought my warrior it wouldn't start and when I got it to start it knocked like nothing else. I debated getting it rebuilt but I was afraid the case was messed up or something and then I would need a whole new case. I started watching ebay for a couple of months and found several deals where you could buy a rebuilt engine for around $700 with a good core. Then, I found a guy on ebay who was rebuilding them and just flat out selling them just a little over $700. So I ended up buying a freshly rebuilt engine for less then or equal to what it was going to cost to rebuild one and keeping the old engine for parts. It still had a good top end and clutch and the new engine came with a new starter. That was a lot better deal to me than anything else.

what is this talk about valve guides or something i dun no that much about engines. do they come with a rebuild kit? i was told to buy this Wiseco PK Piston Kit - DennisKirk.com

i have someone that will put it in for my for cheap but is that all i need?

 

valve guides are in the head.warrior are very common for them to wear out you won't hardly find a warrior that dosen't smoke when you first start them thats be cause the valve guides wear. sort of of like valve seals being bad sometimes mistaken for this. make sure you have oil in it start it up let it warm up and see if it still smokes if it doesn't your valve guides are bad.When they get hot they swell and seat better but if your getting oil in your exhaust I would say your gonna need a rebuild more than likely a bore job don't order anything till you tear it down because you don't wont the wrong parts after you get your beast up and running make sure you keep the oil changed because warrior are bad about rod bearings too but you will have no problem if you keep oil changed with a quad or motorcycle oil. all oil is not the same if you use car oil you will be replacing clutches soon I like honda oil for my warrior hope this helps
