oil filter drain bolt

Recommended Posts

I was removing some oil from my 00 yz426f, because it had been over filled. I tried to remove some oil from the oil filter drain bolt, but no oil came out. I warmed up the bike for 3 min. I was able to accomplish the task of getting the correct amount of oil, but I am concerned as to why no oil came out of the oil filter drain bolt. Any help or suggestions welcomed. Thanks in advance. :cry:

Its a dry sump system , oil only ends up in the bottom of the case after setting for some time. If you take the bolt out of the frame in front you will get more oil out. There is also a drain bolt in the filter cover, the bottom bolt in the cover will allow you to empty the oil filter area before you take it off and spill whats in there all over the place. I chose to lay the bike on its side , all the way on its side when i do the oil filter . :cry:

I never use the allen bolt at the bottom of the filter cover for a drain bolt because it really hasn't ever worked very well for me. I understand that either the threaded hole for that bolt runs open on the inside end into the oil filter cavity, or that it's cross drilled at some point, but it doesn't do much for me. I think it's just a matter of there not being an adequate vent source to allow air into the filter well as oil drains from it. Using it for that purpose can cause problems with the threads if metal debris from the filter well remains in them. That will cause the reads to be damaged or worn as the bolt is replaced.

If I wanted to lower the oil level, I would use the frame drain.

Thanks for both reply's guys. I was just concerned that no oil came out of filter cover, drain bolt, I removed it all the way out, but nothing came out not a drop. I did use the frame bolt to remove the oil and it worked just fine. Thanks for the advice and help, it's nice to have people like you guys here. Thanks again. :cry::cry:

      Selling an FMF Power Core 4 exhaust system off my 450FX. Exhaust has 80 hours and is 100% functional. This will also fit the 14-15 YZ450F and 16-18 Wr450F. If needed I can also include new muffler packing although it does not need it.

      I have a 2008 YZ450F with a stock header pipe and Pro Circuit T-4 Slip-On Exhaust. I'm 99% sure the slip on is shot because its loud as hell and when I take it off and shake it it rattles. I would repack it but the screws are all stripped ect.
      Anyways I've gone over the carb multiple times and I've got it running pretty well. The only issue I have with the bike is that it sputters and pops around 1/2 throttle when I hold it there. When I give it full throttle from any RPM it runs great or when I give it about 3/4 throttle it spins up like a top to redline.
      Initially the popping and sputtering was way worse I made the situation better by moving the pilot jet up in a few sizes from a 45 (stock) to a 62. The issue has gotten way better since then but I'm not super sure what to do from here. Should I keep moving my pilot jet up in size because that's a pretty large jump right? I tried changing my needle clip position but that didn't help much if anything it just made starting it worse and little to no impact on the ride.
      Any input on this would be helpful. I don't want to buy other slip on. Also as for the rest of the carb I'm very sure everything else in it is what it needs to be at. I've replaced all the gaskets and O-rings cleaned all the jets, valve holes ect. fixed the accelerator pump timing. I just thinks its strange that my pilot jet size is going so far from the stock 45, but all symptoms point to the bike running lean.

      Hi I was wondering if y’all have been using a 450 on your YZ250F?

      Excel Takasago 17x3 front and 17x5 rear supermoto wheels with Metzler M3 tires in very lightly used condition. Less than 200 miles total on the setup. Warp 9 spokes. Rear has a Talon hub with 45T Sunstar steel sprocket and OEM rear disc, and front has a polished OEM Yamaha WR450F hub (for the stock speedometer), with a Motomaster 320mm disc. Included is a DID gold o-ring chain, 14T front sprocket, and front brake caliper adapter for a truly turn key setup. Everything is in excellent condition, not a single scratch on these wheels. Came off my '11 WR450F, but will fit many different Yamahas with 20mm front and 22mm rear axles. Asking $1400 plus shipping.
      **Will be driving up near Atlanta, then to northern Louisiana, OKC, and down through Dallas and Houston, TX soon -- can meet or deliver if in the area (Aug 31-Sep 9)**
