Where is 2 stroke oil resivour - 2005 Derbi GPR 125 Racing

The water is going out the exhaust pipe due to a bad head gasket or crack in the cylinder head.

Judging from what discription you are giving me I would say it is a 4 stroke, so make sure you have either sae 30 or 10/w30 oil in crankcase where it says oil and petrol (gas) in the other tank. 2StrokeJim

yes normal , its just agitated oil ...., white foamy oil NO...

If it has a 4 stroke engine, as most lawnmowers do, then you just car engine oil. Very occasionally you come across 2 stroke mowers.

The way to know if it's a 4 stroke or 2 stroke engine is, if it has an oil tank it's a 4 stroke engine. If there's only the one tank, i.e. you mix the oil with the petrol then it's a 2 stroke engine.

If it's a 2 stroke engine you mix petrol and 2 stroke oil at a ratio of 40:1

Gasoline only usually means 4 stroke.
2 stroke requires a mixture of gasoline and 2 stroke oil'
Look for an oil filler cap on the equipment, no oil filler cap means 2 stroke.
If you have an oil filler cap there will be a dipstick therefore your kit will be 4 stroke.

Hope this helps'

You can use any brand of two stroke oil as long as it says on the container that it is suitable for air cooled engines and you need to mix it at a ratio of 25 to 1. Regards Phil

2-stroke gasoline engines don't use a reserve of oil in the crankcase the way 4-stroke engines do. Instead, you add oil to the gasoline to ensure lubrication of the engine. The correct ratio to mix would be in the owner's manual.

sounds like you need to blead out the hydraulic clutch fluid. the resivour is located next to the brake fluid resivour drivers side corner. blead through the slave cylinder on the transmission and check for leaks

i guess your asking if its a 2 stroke or a 4 stroke right ?
2 stroke engines dont have an oil filler cap , just a fuel filling point, the fuel used in a 2 stroke is just normal unleaded (aus) but you mix 2 stroke oil in the fuel before filling (about 50/1) or whatever it recomends.
4 stroke uses the same fuel but you dont mix the oil with the fuel , it has its own filler point for oil , however you must use a 4 stroke oil with these .
hope this is what you were after.

Remove the bottom engine covers. You will see a plastic petcock on the radiator. Take that out and take the radiator cap off.

You have to use Hydaulic Mineral Oil. Call a parts dealer shops use or call your dealer. If you use any other fluid it can cause system failure.

As for wiring diagrams im not sure.
