Yamaha TRX850 Enthusiasts Forum

Thanks to everybody so far for giving me some tips in both this forum and the TRX Facebook page, the garage that have attemted to repair my bike have told me that they cant pick it up until Tuesday, worried that this fuel in the oil is damaging my engine i tried to drian the oil last night but there is still oil/fuel in the sight glass and only about 1.5 litres has drained out so far.

why wont the rest of the oil/fuel drain out, even with the sump plug removed and the oil filter casing removed ?

there are two drain plugs.
look up under the front of the sump.
cheers

As fung said, look under the sidestand side of the sump at the lowest point, cant remember the sump pplug hex head size but it`s a 14 mm thread so my guess is 17 or 19mm. You could flush the oil tank with some clean parrafin if you have the oil filter housing off too.

I have removed one sump bolt that had a X-head, it was a 17mm fitting on the bolt, not sure where the other one is as dont remember there being another drain plug, will look again tonight when i get home. Any one got a picture of this other volt i need to remove.

Thanks

if you are really really really quiet about it, search for the pdf manual somewhere here on the forum.
shhhhhhhh !

Yep that sounds like it, my original sump plug had a philips type screw head in the middle of it, I don`t know why though . Anyone who tried to undo it with a large philips screwdriver would have to have arms like friggin Popeye!

Think its to locate/remove, once loosened!

I think the man is wanting to know how to drain the oil tank, as well as the sump. As in, "still has oil in the sight glass". If you locate the long bolt on your filter housing, that will drain your tank.

Indeed. Mrankh, have you removed the oil filter housing `complete`?
You can remove the braided look oil hose (black) from the back of the oil filter housing spigot too if you want to get every last bit of compromised oil out.
