jallen69 Posted July 17, 2011 Share Posted July 17, 2011 hi!! just bought a dtr125 2003. there's no pattern just does it as and when it likes, some times when pulling away or when your in 3rd gear reaching 8rpm! always random, the previous owner did say it hasn't been serviced for a while. so tomorrow i'll give her a full serivce! it also has a aftermarket exhuast on it, so would i need to check that it's jetting ok? but surely the previous owner would of sorted this as it's been owned by the guy from new! and by the looks of the exhuast it's been on there a few years! thanks josh Link to comment Share on other sites More sharing options...
jallen69 Posted July 17, 2011 Author Share Posted July 17, 2011 hi agian paul, i tried the new plug and it made no difference. they didn't have any BR9ES's so he gave me a BR8ES and said it would run better with the dep can? it hasn't got any better or worse! so, i went to a mate and he rode the bike and he suggested that i clean/change the air filter. so me and a friend tried to clean it, but it just fell apart!! i did give it a quick plip up the road with no filter and i went really well! not 100% but at least 90%, still spluttered a little but nowhere near as bad! so with the no filter we tried making up one out of sponge but the bike wouldn't run properly, then we but a cloth over the inlet under the seat but it wouldn't run, this was only temp so i could get it to the bike shop tomorrow. so i'm hoping i can pick up a filter tomorrow and it'll all be ok?? another thing i've noticed is that there's a very faint knocking nosie coming from the head, my friend said it's normal but i'm a bit unsure? i've made a video of it running if you take a quick look? any help would be great, as i'm getting very worried now thanks, josh i think i put my original thread in the wrong section. sorry about that.
