How Much Engine Oil Does A Honda Dash 125 Take?

[usrefugee]

I just bought a used Honda dash 125 for running around town, but have now attempted to change the oil and now have no idea how much oil to put in as there is no window on the engine and no dip stick on the oil cap. I have tried google with no luck, so if anybody has had one of these or knows how much oil it takes I would greatly appreciate the info.

The Honda Dash is a 2 stroke.

It wont have a sump or dip-stick unless you count the rider

The oil mixes with the fuel some times you have to put it in with the fuel in the fuel tank.

Older scooters usually take about 5% (20:1) - 6% (17:1) and newer scooters are usually 2% (50:1). I have also included 3% (32:1) because many tuned motors use this ratio.

Newer models have pre-mixing tank you pour the oil into (make sure you use 2 stroke oil) and the mixing is done automatically so best to ask the previous owner or consult the owners manual, try to down load it from honda.

Try looking for a small bolt that you screw out that leaves a hold through to the sump.. Then fill to that level when the bike is upright..

A common way its determined if no window.

Every 2 stroke I ever had was a wet sump..

Of course they take oil in the fuel ALSO.. But the idea you run a dry sump on a 2 stroke is 'dip-stick' advice..

The common two-stroke engines that consumers regularly come across (such as motorcycles and power tools) cannot use regular sump lubrication, since the crankcase is being used to pump fuel-air mixture into the cylinder. Traditionally, all moving parts of the engine itself (big-ends, little-ends, main-bearings, and piston/ring assemblies) were lubricated by a pre-mixed fuel-oil mixture (at a ratio between 20:1 and 50:1). Increasingly, even small two-stroke engines have pumped lubrication from a separate tank of oil.

I think you will find your advice is dip-stick nonsense as 99.99% of 2 strokes do not have wet sumps!

There is even a nice little diagram to show you how 2 strokes work

Instead of trying to take the piss out of me why don't you just answer this guys question and you might not look so foolish?

Check out that gif it is quite good it even shows how back pressure works.

As a norm lubricant in a 2 stroke engine works on a total loss basis, you just keep adding it to the fuel or filling up the oil tank/reservoir or what ever it's called, you don't have to change the oil because it has been burnt in the system already.

There are a few exceptions to the rule but I don't think the Honda Dash is one of them.

Keep on trucking

2 stroke field bikes of my youth all had oil in the crank case..

Gearbox lubrication ??

Just looked and my first bike.. The yammie FS1E (fizzy)

http://en.wikipedia.org/wiki/Yamaha_FS1E

"Engine: Two Stroke 4.8 bhp (3.6 kW) rotary disc valve induction, single carburettor, wet sump, 4 gears, with a 20: 1 mix of petrol to 2 stroke oil."

But I owned other 2 strokes to.. RM125, CR125, RD350.. ALL had wet sump 2 strokes (from my 2 plus decades ago childhood memory)..

[JUDAS]

Well, I got a few 2 strokes and they all need gearbox oil......

[LivinLOS]

Thinking to my 50'c.. DT50 MT5 and MTX50..

All took crankcase oil..

So thats getting to 6 I can remember owning.. I cant remember if my ossa or bultaco were 4 strokes or not ?? 2 many bikes

Dash engine with oil filler cap.. Is that not a window or filler level bolt about 1/3rd back from the front ??

LivinLos, your last post got me reminiscing. Was thinking about my old Yamaha FS1E I had at 16, great 50cc bike. Looked on Wiki and restored models now going for 3,000 GBP

[LivinLOS]

Had a FS1E and a SS 50.. Even then they were old !!

Yet would still fly past any 50 of that era !!! They came from the unrestricted stage.. So many happy nights bush bashing em round fields as a kid..

I think you are all getting gear box oil and engine oil confused.

Engine oil multigrade goes in there..

No that's were the gear box oil goes, that filler will not lead to the crank case there is no sump chump the engine oil goes in the fuel, and the gear box oil goes in the gear box.

Can you look at that animated giff it shows exactly how it is not really possible to have a sump in a true 2 stroke.

2 strokes with sumps are either huge diesels with dry sumps or they are 4 stroke engines converted to fire on 2 strokes for whatever reasons and they are very rare and you dont find either of them on mopeds

Just incase you still dont understand how a 2 stroke works go have a read on this link.

Thats the oil hes trying to change..

Assuming we are talking about the 4T engine/gearbox oil? At a guess I would say at least 700ml Most bikes of this size are between 700 and 850ml, with the two strokes needing slightly less oil (no piston to lubricate; thats done by the 2T). 750ml? Normally the amount of oil required is written on the crankcase by the side of the oil filler. I just measure out this and pour this in.

If we are talking about the 2T then you just fill it up (that would be under the seat somewhere and not on the engine casing). If you are unsure, buy a small bottle of 2T.
