Oil level for RYCA modified LS650?
09/07/12 at 12:52:37

The RYCA conversion tilts the whole bike forward maybe 10 degrees which would make the oil-level sight glass a teense higher in relation to the top surface of the oil. Additionally, the sidestand is rewickered,.. I wonder if that changes anything for a check of the sight glass while on the stand.

Anyway, I have the oil level set such that with a hot motor idling, I see a little bit of oil in the sight glass,... maybe 1/16" up from the bottom.

This is the HOT TEST that is recommended for all modified bikes. Sounds like you have tried to do the HOT TEST, but it is unclear if you were holding the bike straight up vertical while you checked the running oil level.

A pass condition is being able to see the top oil level at the top of the window while the hot idling bike is being held vertical. You need to do this, and if your window is full remove enough oil so you can see the top level in the window while the hot idling bike is being held vertical.

The bike was vertical. I was on it, holding it vertical, looking at the sight glass with an inspection mirror (mirror on a stick).

Reply #7 - 09/07/12 at 19:28:39 Just out of curiosity, how low can the oil level go and not cause damage? Let's assume we are cruising at 55 on level ground on a 70 degree day, so extreme heat is not the issue. In this motor, does it have to get down to the point of the oil pump sucking air?

Get it pretty low in the window, now go downhill and brake sharply at the stop (you just sucked some air).

Get low in the sump and then rock your oil pool forward sharply and you can expose the oil pump pickup.

Doing it backwards (accelerating uphill) is tougher to do, but it is possible.

You can keep the recommended amount of oil, still it is not bad to have a LITTLE more oil added. A half quart seems to me to be the absolute peak value of oil to be added.

The oil pump sits nearly right in the center of the engine's floor and that's the point all the oil flows back. If you tilt the engine a good bit, nothing changes in this meaning. Only the sight glass moves up!
Fill in the recommended amount, add a bit and make some new marks for the oil level.

The gearbox, crankshaft and all this is provided with oil from the oil pump, so don't matter about this in case of tilting the engine a bit. The gears don't use oil from the oil sump by paddling in it. The bearings are fed from the oil gallery, and by leaving them it sprays around, and that way it lubricates the gears and shifting mechanism.

And what you see in the glass when the bike is idling is flowing oil which just left the gearshafts and being centrifugated by the clutch.
It is not an oil level. By tilting the engine the visible flow may change a bit, nothing else.

Every engine must overcome short times without oil pressure. Hard accelerations and quick stops belongs to that as well as starting the engine. Manageable moments for ball bearings anyway, but care of the camshaft journal bearings!
Running them without oil for period will ruin them quickly. So care for your oil level your own.

Reply #14 - 09/08/12 at 07:08:10 Drop rear wheel in a low spot, front on a high spot, whatever, frame angle "stock", check oil, then look at where it is on level ground. We've seen people add oil till they could see it in the window when it was on the side stand, no damage.
