Hi Jim I must have put the valve in the wrong way round as the pully was conected in the right position and the cables were fitted right ...........i didnt look when i put it in i know my bad ! but i turned it 180 this morning and its now fine ooooooooooooooh i didnt squeeze the rubber pipes shall i just drain it again and refil it properly or will it just sort its self out? Regards Mark

Well ive turned it 180 and it seems to be how it was now One last thing i now have a coolant leak from the underneath frame next to foot peg on the last hand side i did drain and refil the system .........would this be just an overflow pipe> Thanks again Mark

Hi Jim Im going to have a look tomorow i should have taken a note of how it was before i removed it How do i know when i have it in the right place how would it look inside if i looked through the exhaust port when its in the right place? would it be fully open .....im getting confused What do you think about the air filter cover ? Regards Mark

Hi Jim Well i have changed the o rings and seal and there is no leaking oil up to now so fingers crossed Now another problem i guess i must have put the power valve back in wrong I no longer have the arm pulling acceleration i had before and it now struggles to hit 70 ...........what have i done wrong ?? Also the previous owner had lifted the air filter covers to alow more air in ........is that normal Thanks for all your help Regards Mark

Hi please accept my apologies for not replying to your comments I did appreciate your help and i was going to let you know about the power valve moving once i had taken it out and checked it Once again forgive me if you think i was been rude but that wasn't my intention Regards Mark

Hi Jim Im afraid it is leaking from both sides but only a small amount from the side with the servo and yes i can hear it turning both ways when i turn on the ignition I am going to remove the cylinder head tommorow and have a good look at the power valve and check the piston rings at the same time Ps whats a PV engine Regards Mark

Hi Jim I believe the valve is connected i am going to replace the orings and seal tomorow and i will check the exhaust while im at it The MPG is a very sad 35 ??? Thanks Mark

Hi Ive bought a 10 year old DT125r and ive had nothing but problems and i was hoping to get some help on here? The previous owner has had it derestricted it had dep exhaust and thats about all i know of the bikes history it has 15000 miles on the clock. 1. i have blach gunk and blue smoke coming from the power valve caps on both sides (ive ordered now seals and o rings for this) 2. Its using a lot of fuel 3.The spark plug indicates over rich fuel/air mixture but the haynes manual doesnt tell me how to fix it 4. the bike is running very poor at low revs and speed i have to change gears very quick as it sputters it feels and sounds like it misfires when im around town but as soon as i go on an open road and about 6k the powerbank kicks in and it nearly pulls my arms out of the sockets and only then does it run fine If anyone could give me some advise and somethings to try it would really help me out Kind regards Mark
