I posted this about a week ago: http://www.gstwins.com/forum/viewtopic.php?t=15104

Basically, someone hit my bike while parked, and now it doesn't have any oil pressure.  I got sick, so I couldn't do anything for the past few days.

Today, I pulled off the pressure sender switch.  I was going to screw a gauge in there to see if there was actually any pressure, but the gauge didn't fit.  Mental note:  it's not 1/8" NPT, even though it sure looks like it.

So, with no other options, I cranked the engine a few times with the pressure sender removed.  No oil came out the hole, so now I know that the sender isn't the problem anyway.

Anyone have any idea what it might be?  I've never had a GS engine apart, so I don't know what's likely.  Is it possible for the oil pump drive mechanism to slip somehow?  Is there a place that it commonly gets clogged up?  I guess I can drain the oil this weekend and see if there's any chunks in it...

Oh, another thing:  I checked the oil level.  It's full.

when you checked the oil did you just pull it out and look at it and saw that there was oil at the full mark or did you wipe it off and stick it back in then look.  I ask because I have done that before when i was in a hurry and later I found out that I was 2 qts low the next time I checked it. the oil will stick to the F mark and the little cross hach pattern making it look like it is full.

I stood the bike up between my legs, unscrewed the filler cap, wiped the dipstick clean with a paper towel, put it back in (without screwing it down), waited a second, and pulled it out again.  The oil clearly reads full.  Also, there was enough light that I could see the big pool of it down there in the sump.  It definitely has oil.

At this point, I *wish* I was just out of oil...  

first thing I would do is remove the oil pan, and look in the oil strainer, and make sure it's not blocked up with pieces of a broken magnet/stator.

Ya...  that's what I thought someone might say.  I guess it's time to find a pickup and move it to the shop...

Thanks!  

why take it to the shop? all you need to do is drain the oil, take the pan off look in there and see if it is full of gunk.

it's only 13 bolts

yeah seriously.  i could have done it just on the centerstand.  just unbolt the bolts, carefully pull the pan off, and look at the screen.



if you can't, for some reason, fit under the bike you can lean it over on a couple of tires

Ya, you're probably right.  If I moved it, I could be out of the rain, but then again, it's all the way over in Oakland.

Don't I have to pull the exhaust to get the pan off too, though?

yes, and that's 5 bolts.


it seriously isn't hard.  if you have a halfway decent socket set, hell, I think it's 10mm?, and remove the exhaust (allen bolts) and a flashlight... and a 3qts of oil to replace what you'll have to drain... you're set.






car dealership rip you off bad.

motorcycle shops, imo, are about 5x worse

Oh, sorry.  I see where the misunderstanding is now.  When I said "the shop", I meant "my shop."  I rent shop space in a warehouse in Oakland (for projects that are not at all related to motorcycles, although I do my oil changes there too).  If I move it there, I don't have to work on it in the rain.  I would have to find a friend with a truck to move it, though, so I'll probably just work on it in the street.

Thanks for the tip on motorcycle mechanics, though.  I've considered taking it to one, but I think I'll mess with it a bit more myself first.

While you're at it try priming the oil pump if it's accessible.  (Not familiar w/ the GS engine yet)  I have the suspicion that, assuming you haven't sucked something up and sheared the oil pump, it may just have lost prime.

Geep, the oilpump on the GS is Driven by the clutch basket gear, and is pretty far from the pickup, the pickup screen is pretty darn tough too.

yeah but if he has goats there's plenty of magnet material to get stuck in there....
