Oil Questions

Thanks for help, that's cleared everything up.
. Is there anything I should look for when buying a dt 125. So you recommend changing piston and rings every 10k is there a kit I could buy online all in one. I know a friend who would do this for me if needs be so should save a lot of money on Labour etc. -

I do piston and rings every 10k because my bike isn't in stock trim.
I had my bike stolen and ramped and battered on the stock piston for 15k miles and it was in mint condition.
I err on the side of caution, but others will be happy to leave the engine till its seriously down on power.
It's cheaper to replace rings earlier than necessary, rather than to have the engine fail and need a full rebuild.
Many people rebuild the head gaskets using cheap pattern parts, only Genuine or Athena gaskets can be used.
In which instance the head gaskets tend to be blowing because people "can't" fix them.
If that's the case it just needs a gentle skim and a decent head gasket. Clues to this will be the expansion bottle missing the little cap, usually the first thing to go when the head gaskets gone.
There will be a layer of black oil circulating around the radiator system, take the cap off and run your fingers inside and you will be covered in oil
The swingarm bearings wear and don't get replaced. Pull the bike on its stand, pull it off the wheels over to you and check the swingarm for side to side lateral play.
This is less common, but is just general advice for DT's.
They're pretty darn strong bikes, there doesn't tend to be common faults that need looking out for.
Generally, pay extra for a better condition one and it'll serve you well.

And note, not all 2-stroke oils are suitable for premix. Make sure it says so on the bottle, unless you mix it up yourself.
Just about any half-decent 2-stroke oil will do, but most use some of the best, as the pricedifference per mile is so small nothing.

What do you think about this oil?

@irongamer727 But the gearbox only takes 750mls....?
@calum I have more than 1 bike and will change for more than 1 time..

I'm asking for oil quality only, which is the best.

@irongamer727 It's subjective I guess. Personally I run Silkolene oils for my four strokes. But currently running Castrol in my Starlet as a quick fix. It's leaking it all over the floor so need to sort that out.

@Calum why not castrol?

@irongamer727 To each their preference. My mate works in the oil industry for motul, so when I need oil I just ask him and he'll bring the best stuff

It just feels so hard choosing. I want the best possible oil for my machines!

@irongamer727 As long as you stick with the bigger well-known brands you can't really mess it up. As for types of oil I use yamaha 10w-40 4t for my gearbox and motul 100% synthetic 2-stroke oil for the engine for all my 2 strokes. If I don't have motul, I just go with castrol.

@minia I run Castrol Power 1 2T Racing in all my machines. Cheap and hopefully good.

Hello everybody, now I'm look at getting a Dt125 as my first bike, now I have a few questions about the oil and coolant. Gearbox oil what oil would I need how much and how often would I need to change it. Engine oil what oil would I need how much and how often do I need to top it up, and coolant is it just any coolant for a car etc how much and how often would I need to top it up. Sorry the seemingly silly questions I just want to to know the rough cost of running the bike before I get one many thanks.
@yamahaman5000 I always found that Silkolene products were very high quality and performed very well indeed.
-
My castrol oil cost roughly £10 for 1l. I found that silkolene for a whopping £22!!
You guys think there is a difference in quality between them?

@irongamer727 You can get Silkolene comp 2 for £15 a litre, which yes is more expensive, but as with everything in life - quality does not come cheap. Some people will say that oil is oil, but all the top race teams will most definitely not be using Castrol oil for-sure.
-
@ninja Alright thanks. Transmisson oil then?
What do you run? -
@irongamer727 Silkolene 75W-90, is what I have just put in my Starlet. Think it was around £75 for 4 litres.
