Picking up my 1990 tomorrow. SST braided hose?

[vegetta58]

Finally found a bike and picking it up tomorrow 1st mod is the RPM oil filter adapter. It has the full SSR 4 into 1 V&H exhaust. Is there any reason you cant mount a braided SST hose coming out of the drain plug hole so you can drain oil without dropping the exhaust. i looked all over the sight and never saw this suggested. Thanks for the help to a newbie.n Mickey

Mickey,

In the oil pan, one place around the drain plug is cut down to the thickness of the metal pan, while in all other places, the metal (and threads) extend upward around the drain plug.  That is done so there is lots of metal threads around the drain plug, but all of the oil will drain out during an oil change.  If you made a hole in the center of the normal drain plug (as I intended), you could not drain out the last inch of the dirtiest oil.  I wanted to put in a better drain, too - I have Vance & Hines 4-into-1 headers.  You need to disconnect the muffler and loosen (or remove) the V&H headers to drain the oil.  I did not find a good way to do that with my headers, because of the oil pan design.  Randy at RPM has custom FJ headers that allow you to change the oil without removing his headers.  You would need to ask him about fitting your muffler to his headers, though.

Cheers,
Red

Here are the photos explaining the "notch" to allow complete oil drainage Red explained above.

I had a '92 with a Kerker header with no room for drain plug access.
What I found works:
1) put the bike on the side stand.
2) remove lower cowl aka chin fairing.
3) remove the left side (as you sit on the bike) oil cooler line fitting where it connects to the oil pan.
4) drain the oil. It will run over the header tube but will easily wash off.
5) buy a half dozen or so O rings, and replace the O ring on the oil pan fitting every other oil change.

I found the 2 Allen bolts holding the oil line fitting to the oil pan a bit cumbersome to get to so I replaced those Allen head bolts with some standard hex head (10mm head) bolts. That way I can very easily get my nifty box head ratchet wrench in there, to loosen and tighten the hex head bolts.

Hope this helps.  Pat

Thanks for the replies. I wish I could afford Randy's exhaust, but mine looks brand new anyway. By undoing the oil cooler line does this get all the oil at thanks.

Perhaps Randy or Robert can post a picture of inside the oil pan at the left oil cooler fitting.

No, it does not drain all the oil out, a tiny bit of oil remains (1oz?) but not enough to make any difference.

I will try and snap a photo tomorrow of a oil pan and the angle of the pan when on the side stand.

Here are a couple of photos of the inside of the pan. I also included one with the pan at an angle. The square at the front looks like it holds most of the oil. There is also the portion behind the oil level sensor.

Thanks Randy, on the top picture it looks like that left side oil cooler return hole is flush with the floor of the pan, and the far left side of the pan, where oil could pool, has a slightly higher floor..

It looks like putting the bike on the center stand would be better vs. on the side stand.

[racerrad8]

I will say it will drain more when on the center stand...not the side stand.

Yep....I was editing while you posted....

Thanks. I really didn't want to drop the exhaust every time I did an oil change.

Consider moving the drain point. I bought a V&H exhaust system many years ago and realized the problem of oil drainage. With some simple machining and welding I moved the drain point to the back and to the left on the oil pan. The hardest part of the job was removing the gasket material from the lower part of the crankcase. Oil changes are now a breeze.

Hein.
