@yegor Hi bud,

240 main jet is fine, in your climate it probably about right. In colder climates then you would want to up jet slightly.

Jets are expensive, I cannot stress enough how important it is to buy genuine jets from reputable sellers.

@Yegor if your Spanish don't bother reading that old notebook crap it got everything you need to know but badly rote and explain get something in your native tongue

@calum yes. those are original Mikuni jets. But what size is the ralenti jet ? 25 or 15 or what ?

@yegor Pretty sure that's called the atomiser. No idea what a ralenti jet is, neither do I know what size it is. I don't run a mikuni carburetor so I cannot help you I am afraid.

[Yegor]

@calum I was researching. I think in english is called " Pilot jet " and Mikuni TM28 pilot jet size is 15.

[Yegor]

sorry, the DT 125 "R" version is 17,5 pilot jet.

Hello, I don't know if is good idea to write in this thread . Today I was checking the oil pump and I realized that the color of the oil changed: it has a suspicious color )
( I have put a transparent tube to check the oil flow)

I think it's because of oil seal or o'ring

11. O-RING
-- 13. OIL SEAL

WHat do you think ? Thanks in advance

Is the pipe suitable for oil?

[Yegor]

@calum said in Time to change wheels and ...:

pipe

you mean that if the material the tube is made of is the right one ? the #3 in the picture.

I put the tube yesterday to check the pump, later I will put the original. I'm going to add oil to the gas tank. 100 ml of oil for 5L gas. ?
with new cilinder and piston ...

I started the bike yesterday after installing the piston

[Calum]

@yegor Yeah, it's gotta be suitable for oil.
