The Yamaha Road Star Warrior Forum

I did my oil today for the first time since buying the bike last August.  I followed the manual and removed both drain plugs.  But I only got about 3 L to drain out.  I put 3 L back in.  The manual states that an oil and filter change should require the replacement of 3.7 L.  Have there been issues with air bubbles getting into the system?

you could have drained the transfer case oil by unscrewing the wrong drainbolt.  i did that once and learned it the hard way.  look on the site for the right way to change oil. there are good instructions and photos.  if you can't find it i may have it stored somewhere.

I followed the owner's manual and only removed the 10 mm and forward 17 mm bolts.  I did not know about the rear 17 mm bolt.  I did replace the filter.  I'll probably run it with the 3 L of new oil and 2 L of old oil (which I only ran for about 2000 miles, but I've had the bike nine months now) for a couple thousand miles then change it all out.  Is that a bad idea?

i let it warm up good, removed a 17m bolt on left front and 10m bolt at rear right near shock and removed the filter. only 2 quarts drained out. there was still oil showing in the filler neck. i then started engine for a few seconds and the rest of the oil came out. filled it up with 5.3 quarts and everything seems okay. don't know why the oil wouldn't drain.

Both oil drain bolts are 17mm. The 10mm bolt is a oil pressure sensor point. The 10mm bolt is the wrong one. The correct bolt sits higher up and is also 17mm.

Been there done that. Also used the ole' turkey baster to get the excess oil out then I overfilled.

Eric,  I just saw this.   Both Plugs are 17mm.

John,

 Thanks for the info.  I didn't think about the oil filters.  That's a great list.  I rode today and found the oil tank bolt after I got home.  I'll probably do a complete change at the end of the summer.  I didn't get that many miles out of the dealership's oil anyway,  but I rode it often enough that it was never parked for more than two weeks through the winter.

Wow, you guys and this site are great. Just did my 1st oil change on my warrior since I bought it late last year. Took less than 20 minutes, found all the right bolts and didn't even burn myself. Thanks to this site and all of the useful information and pictures it was a piece of cake.

ok guys i just did my oil change for the first time on my 2002 warrior and i must say that after reading everyones questions and problems they have been having i was a little scared to even try it,i am mechanically inclined and i like to do things on my own so i went ahead and tried after reading as much as i could in the forums and now i can say it wasnt bad at all in fact real simple,i followed this link http://roadstarclinic.com/content/view/158/116/  they couldnt have made it any easier,once again thanks to the forums for providing the info for us backyard guys to do it ourselves and save some money,THANKS AGAIN GUYS
