Hi. Does anyone know if the rear wheel (with alloy rim) from a 77-ish xt500 or even the alloy-rimmed rear wheel from a later-model dtmx can replace the stock steel-rimmed rear wheel from a 75/76 dt400? The wheel bearing ID is the same. I know that the brake backing plate is different between later model dts and the 75/76 wheels, but a suitable replacement from a xt wheel (or even possibly one from a 75/76 dt) will likely work. Any help would be appreciated.

Can anyone tell me for sure what year my Dt1 250 F is? Thanks

I have a 1981 DT-100J that I need help with. The muffler and guards were taken off and the bolts lost. Does anyone know how to get a parts breakdown for this bike. I also need to get the bolts for this bike, can anyone help? Thanks Hans

Hello, I was just wondering if I have to mix 2-stroke oil with my petrol? I haven't been mixing oil with my petrol but I do have oil in the engine itself. I'm taking it out this weekend so I don't want me wrecking the engine because I don't mix oil with petrol. Thanks! I'm talking about my DT-125

Hello, I purchased a DT-175 from a friend of mine, with the intention of restoring it. Neither of us have any idea what the year of the bike is, but our best guess is 1973-1975 area. Is there a way of discovering exactly what year it is? Thanks, Jeff

Hi i recently rebuilt a 1977 DT100 and it was all working fine then 2 weeks before its MOT it decides to develop problems. The bike will run but only if throttle is applied and the engine doesnt like it its also spewing out white smoke and it smells rather strong of something but im not sure what it is and if i go more than half throttle it dies and it is impossible to pull away. any ideas would be highly appriciated as i really want it to pass as this is my first build

how can i make my tdr125 go faster

I must stay off gumtree..here are a 1981 DT125 & 175 for sale for 420pounds for BOTH. Both good running condition but neither has papers. They still look very original...soooo tempting...but having 5 DT`s really getting bit much.

Hi, im new to this site and am looking for advice, just wondering what back sprocket i would need to make my bike come up. anyone got any advice/ideas, let me no.

so, the previous owner of my 05 DT125RE was a bit of a wally and has screwed the air mix screw too tight and ended up shearing off any sort of groove for my screwdriver. I have just come off the phone from my local yam dealer and we had a great laugh at a new carb being over 400 quid! So I am now searching the internet for a second hand one but I am unsure what year/models will fit my bike. also any suggestions for good sites to look at would be much appreciated or even if anyone on here is selling one or knows someone who is. all help much appreciated!!

Does anyone know how much engine a 2 stroke DT125 should use - how many miles should a tank full of oil last or how many tanks of petrol should it last?

Hello, ive just got myself a completely standard 2001 imported dt125. I’ve been looking at dep exhausts for a better noise and possibly better performance? Any one know if they make much difference and weather it’s worth changing the front pipe as well or just go with the silencer on it’s own? thanks in advance lee

Hi, Michael here i am still new to bikes and have recently when through changing my brake pads, however before attempting the front as i loosened it a split in the caliper appeared and it has lost all its compression. i have ordered some quicksteel to attempt patching it in the mean time however, the main reason for the post is this: What can the caliper be replaced with if not the original dt125r ones as it currently has a dt125x caliper on it. (was like this when i brought the bike) The main thing im concerned about is what will fit. =)

Hello, i've just bought a 1985 DT125 lc. matey boy who i brought it off says it has just had a full engine rebuild and it was fitted with an over sized piston not sure how much bigger it is. i know i need to upjet the carb but im not sure what size to get?? whats the standard size thats in it??

I'm really wanting to make my dt125 R 1989 full power with the servo, does anyone know if i would be able to put an dt125 R 2000's servo on my dt125 R 1989 it has the 3 wires but would it work ? thanks for taking the time.

A friend of mine is rebuilding a 2004 Dt125re, the bike was bought as an incomplete project the engine fitted is a 4GW which I think is a TDR. The engine runs and sounds sweet but the only problem we have is the YPVS system dosn't work, It originaly came with a 3 wire servo that didn't match the loom, so we aquired a 5 wire plugged it in, nothing, The wiring loom looks to be the original and we've checked it for condition & continuity. What I do want to know, is if there should be power to the YPVS servo when the ignitions turned on, so that it can go through its cleaning process, if so ,where does the power come from ? my guess is the cdi unit. The CDI i…

Hi I have recently bought a dt125 re 06 reg, I have bought a big one full exhaust system for it, is there anything else I can do to increase power and how is it done? Also would love to put SM wheels on it, but seems quite expense, is there a cheaper option to do this? Been looking for second hand wheels but not had much : ( Any help or advice would be great! Jo

Hello there! I recently purchased a Yamaha dt 125 RE 2004, it's been nothing but trouble and all I've done is thrown money at it, it's an amazing bike though regardless I've sorted most of its problems now I'm stumped and was needing some help, the bike never starts very easily and never settled when its idling (revs keep going higher and lower) and just yesterday it feels as if the power band isn't kicking in anymore.. Anybody got any ideas as where to start? Thanks!

Hi, I have DT125 (03) with a leaking rear shock. I have purchased a replacment part but was wondering easy it is to fit. It apprears to me that its just 2 bolts, one each end, Is it really that easy. Any advice would be much appreciated, even if its take it to a garage! Thanks, Andy
