DT 125R MAN

right ive cleaned out the carb with some carb cleaner used a whole can to make sure its nice and clean! but still wont run with out choke other thing ive just noticed is the boost bottle is missing he has just pluged it up :/ could this be why i wont run right? cheers

yeah it has been done because for a start the old piston had smashed

thanks for all your help one thing i did try was unpluging the powervalve and then reving it up to where i had heard the noise before and with it unpluged it does not do it :/ cheers

it was a guy who used to work for a motorbike garage for many years! i had a new piston rings rebore new big end and small end bearings :/ ok cheers ill get on with the carb now

did not think it could hit was just checking tho so thanks for clearing that up is there any way to stop dettonation? ive only just had the engine back from a rebuild its not even done a mile yet :/ cheers

afternoon all, right ive finally got my power valve working a bit better when i turn the key the powervalve sets up and is inline with the dot/hole on the head ok and when the bike it running it move with the revs ok but when the revs pick up a bit and the power valve goes about a centimeter clockwise a rattling/knocking noise appears :\ is this normal? im guessing the powervalve cant hit the piston because i wondered if that was the noise? also i cant seam to get the bike to run right it will start fine on the choke and idle at about 2k and when warmed up ill take her off the choke and the revs pick up to about 2.5k for a few seconds and then the revs will start to slow down untill it totaly dies and if i go back onto choke will bring revs up to 2k again but after a while it will cut out! but if i keep the throttle on a little it will stay running fine:/ any one got any ideas? cheers

hi all, right i have a dt125r and the powervalve is a bit stiff on it what can i use to greese/lube it up? cheers

ok does it really take 200 miles to run it in cheers?

hi all right ive had my dt 125r engine fully rebuilt! was just wondering whats the best way to run the new piston in? cheers

hey i have a dt 125r 2000 plate its been very good to me but now i have noticed my bottom end has started to rattle a lot more than usual and my gear box oil keeps going below minimum in less than a week so im guessing its going up and getting burnt some how (no leak been checking) so i think its time for a rebuild ! im looking for a bigger bore kit around about 170cc i have seen one for £400 but i dont really want to pay that much! does any one know of any other kits? cheers
