dtrliam

Thanks for that i'll give that a go

sorry about that it is a 1998 model with a servo motor i think i'm suffering from fat finger syndrome pressing the wrong keys lol

Hi guys can anyone tell me the correct way to adjust the power valve on my 1989 dtr125

yes the rings and pegs located correctly, no the ports have'nt been opened by me perhaps a previous owner/s did ? the piston damage is on the inlet side of the piston in the skirt area and no there is no hole in the top of the piston would a badly ajusted power valve cause a piston to jam ?

Please help i've recently brought a dt 125, and after having a look over it i decided to have the barrel rebored . after refitting the new piston in the rebored barrel and starting it up. it ran nice on tickover untill abit of throttle was used and then pop. removed the head/barrel and i now have a smashed piston , so purchased a new piston checked the port edges for smoothness replaced everything again started it up. again tickover fine a few revs and then pop . any ideas guys regards liam

Hi guys i'm new to the club so be gentle with me i've just brought a dt125 what i hope to have up and running soon
