anyone use the "ManFunnel" for your YZ?

9 posts in this topic

Curious how this thing works. Just purchased an '02 YZ426 & I can see how the oil changes could get messy.

Also, I haven't done a change on this bike yet - what are the procedures for changing? My KTM requires you fill the frame thought a separate plug, then run the bike 'til oil comes out ... there's a few steps.

Anything like that with the Yamaha?

Never used the ManFunnel myself, but I made my own cheap funnel that makes drainining the oil out of the frame easy. Just take a plastic water bottle and cut the bottom off at an angle. Then you can hold the bottle vertically up to the drain plug while it drains into a container on the ground. Although you have to hold it while the oil drains, unlike the ManFunnel it is cheap and easy to do. It also keeps the oil off of the front tire. Hope this helps. :cry:

1. slowly remove dipstick and clean it

2. remove the engine skid plate

3. drain oil from frame drain plug(be careful, it shoots out pretty far)

4. drain oil from engine drain plug

5. drain oil from oil filter drain bolt

6. remove and clean the oil strainer

7. remove and replace the oil filter

8. reinstall everything(replacing sealing washers and o-rings as needed)

9. fill with oil

10. slightly loosen oil gallery bolt

11. start the bike, oil should weep out from the loosened oil gallery bolt(if it doesnt within a minute shut it off, u have a problem)

Try this:

Your '02 is a dry sump system. The frame is the oil tank. Oil is pumped through the engine, then picked up and returned. Yours should fill at the frame, and has a capacity of 1.7 liters (1.6 for an oil change with a filter change, 1.5 for an oil change without a filter).

:cry:

You don't need to remove and inspect the oil strainer under the skid plate at each oil change. Once in a (great) while is fine.

Can't quite make out what the manual calls an "oil gallery bolt" even after viewing the manual? Any specifics? Yes I'm a newbie!

Thanks.

The oil gallery bolt is used for checking oil pressure. After changing the oil, loosen this bolt while the bike is running, oil should seep out. As soon as this happens tighten the bolt and you are good to go. :cry: Just follow the manual closely and take your time. :cry::cry:

Hahaha the man funnel. Picked it up about 4 months ago out of a clearance bin for $5, got home and tried to use it only to find that the only drain hole it fits is the one on the frame. It won't fit the drain holes on the crank case. So basically now all I have is a wierd looking funnel that doesn't work. It is useless on my 03' 450, dam false advertising.

Yea, I hate to say that I bought a product that I didn't need but the ManFunnel for my YZ-450 may be one.

It really doesn't help at all except with the frame tank in the downtube and that is easy enough to drain using a standard funnel or homemade one out of a milk bottle, etc.

It doesn't work for the engine drain, or the drain bolt under the shifter. At least, I can't get it to work for those.

Maybe I'm doing it wrong, but I don't think so.
