DT125R FORUM

I had exactly the same problem on my old DT, its because i decided to fill it up with magnatec oil which is used to hold to components so they are covered in oil before starting, however this is useless in a wet clutch bike, even with new oil they still stuck, so i removed them all, cleaned them in paraffin along with the pressure plates and spring, and then dried and coated them in new oil. i think i even changed the clutch springs because they were slightly under tolerance and only £10 or something.

this worked perfectly and i only ever ran the bike on halfords special oil from then on as thats what it was happiest on.

@Calum ive done what you said, i disconnected the servo and pegged the valve open, bands at about 7-8k now which is what it should, did a speed run aswell and got it to 60 now, then i think the carb gives up.

I may try upping the jet size to a 240/250 rather than the 210 thats in there now as i have a full dep too

If that dosent fix it then ill probally do a carb swap with another one

Got a new set of cables and a new pulley comming too so ill see if that helps

Its all apart now, plates were cleaned with paraffin and are soaking in the oil i will be using, they have loads of meat left on them so they should be fine, should i put the metal plates and ring in the oil as well?

basket and cage are good, however the springs weren't, 2 mm below Haynes serviceable limit, will order a new set soon,

when i removed it they were literally glued together, my fault really, should have disassembled and cleaned before putting in but i was just lazy.

will keep you all updated

The Leak has been fixed!,

it was the clutch gasket after all, it had split and some of it was inside the casing.
put on a new Athena gasket and its all okay now.

however a few more problems have arisen now and i dont know where to start.
firstly my clutch is slipping a lot more now and it probably has to be replaced which i dont mind doing. this may be the oil i am using (Castrol magnatec 10w40), i saw a post ages ago with someone having the same problem.

however the main thing is now the kick-start sometimes does not engage when it is kicked and the bike has to be rocked for it to work again.

if im not mistaken this is also because of the clutch?

regardless of the kick start problem, i have to disassemble it again soon for a clutch rebuild,

does anyone have any suggestions on a clutch kit?, and a bolt kit for it as the ones i have now are not too great. and maybe some advice on the kick start problem?

thanks
