No oil pressure when doing wheelies

[Emil123]

I´ve got a 450 SM -06 and I have discovered a terrible problem. It doesn´t take many seconds on the rear wheel before the oil light comes on.

How do you do? Just keep the the front wheel down or has anyone of you a good solution?

I´ve thought about the oil level, should I dare to fill up a little more oil if it matters or will it just damage the engine?

Don´t wanna do any bigger surgery right now, but I might have to? Because you can´t have a motard that don´t wanna wheelie!

i would think there would've been some usefull reply to your problem,but nothing sofar
it's true, you can't not wheelie with a motard...it's one of the most fun things to do

anyway,hope you get a solution soon to this problem.
maybe fill the oil to a litlle higher level.

ciao, hannes.

I have the 06 enduro. Doesn't like extreme hills and flashes the oil light, especially if a little low. I overfill a little to minimise the problem. I assume the 05 is fine with the dry sump. It may be that other bikes do this as a many enduros don't have oil lights.

i have an 07 and it does the same thing. i fill it to the top of the top sight window which is about 850mls. the manual says it takes 1200mls when changing filter ,but i always thought a sight window was supposed to be in the middle . anybody try to put 1200mls in? if so, whats the result?

I don't know about the SM but if you search around for info on the Moto Guzzi V11 oil sump, it had the same problem under hard acceleration. They solution was to put a baffle in the middle of the sump so that the oil wouldn't slide all the way to the back and will keep the oil pressure up.

no issues alway put in 1200ml after a filter change, i put in 1050 mls without filter change.

yeah, a windage tray of some kind would probably fix the problem for short wheelies/uphills - but for very long wheelies, additional/relocation of oil pickup may be needed..i'm not familiar with the sump on the 4 strokes to see how do-able this would be.

Fastisbetter, your 07 should have 2 sight glass windows, of which the level is supposed to be between the two.

well thats good to know, what are the sight glasses for?

 

[fastisbetter]

sorry, just read your post Nick. 900mls puts it over the top window

ok, I just called the dealer and am now more confused. He says drain the frame. I was under the impression that this was a wet sump and therefore wouldn't have oil in the frame. how do I drain the frame. And if I get it drained, is there a specific procedure on getting it filled again. I'd really like to get to the bottom of this.

 

[Qui-gon]

Try this:
Get the engine really hot then drain the oil and change the filter. Leave it draining for as long as possible leaning it left and right periodically to make sure you have as much of the oil out as is practical. Refill it with 1200cc of oil which is supposed to be the capacity of the 06 and 07 bikes. Make sure the bottom window is covered and try it. If you have to much oil in it will find its way to the air cleaner box.
Some earlier models have a drain in the front frame tube. neither of mine do but there are 2 pipes that go to the bottom and side of the frame. It is some kind of excess oil reservoir/breather arrangement I believe.

Just found this thread. Emil, my bro shot this video of me just before you posted this thread. I titled it "GasGas: Eventually the Oil Light Goes On". (Between the single track trailheads on this side of the mountain there is nothing to do but slide the corners and wheelie the straights.)

Hi, I have the same problem with my 450 FSR SM '07. Do you solved this problem?

Maybe... Ive since replaced the engine, so I dont know if this would have worked with my other engine, but with 1000cc's oil, which is over the top sight glass, oil light comes on as soon as I grab throttle, without even really lifting the front wheel. 250 more cc's and the problem seems to have disappeared.
