DT125R FORUM

I was stripping down the top end when I found a gold coating on the inside definitely interesting

Does anyone have any ideas ( the bike ran fine until the top end went )

Turns out my top piston ring went for a walk, full top end Rebuild in progress

My mate has one ill borrow it this week/weekend

As I said earlier I cannot check my compression at the moment but it does feel like I have some

When I checked my radiator I found my finger was dirty and the cap had a milky residue

I've heard before the milky residue could be a sign of a head gasket failure

To be honest I have no clue about the age of the Engine as I bought it last August and it came with like 3 top ends and a bottom

I'm getting a compression tester from a friend sometime this week.

What kind of residue would I find in the cap ?

Hi all, I have a 99'DTR and after leaving a bike meet the bike felt slightly sluggish, this got worse as the trip went on and when I pulled over to check it cut out when I pulled in the clutch. The bike no longer starts and I have no clue what it is I have cleaned the carb (not incredibly thoroughly and have cleaned and have spark. (Yes I do have fresh fuel)

Sometimes when I try to bump it will bang if that helps at all

(Sorry if this is in the wrong page )

Hi, all I was just wondering if this seams off ?
I'm reinstalling my exhaust as I had a leak from my exhaust gasket and I cannot seam to get the exhaust to go on in another way apart from this and I think its too close to the frame

@Calum i have no clue haha the last owner didn't have much of a clue so i doubt that helps, but thanks for the help !

@Calum I would rebuild it, In fact that's what I tried to do at the start but it didn't work and turns out that my caliper was corroded and beyond repair

Hi all I've been having trouble with my bike recently and turns out I need a new front caliper. After ordering one off eBay it turns out the seller sent a back caliper. I would appreciate any help I could get as I desperately want the bike ready for the road by the 18th as it's my 17th and I will be all ready to go

@Calum I think it was a false alarm, I went out to the garage today and it's cleared up

Hi all I was working on my bike today when I noticed a haze in the tach (see image below) does anyone have an idea what it could be

It may if been brake fluid as I've been working on my front brake but I don't think anything has touched

Hi everyone, I just had a quick question.

I bought my DTR last year and my fuel cap key isn't the same as my ignition key, is there anywhere I could get a fuel cap cut to the same key as my ignition (or vice versa)

Thanks in advance for any help this form has been amazing

Hi there I've ran into an issue on my 99' DTR. My front Brake pads are sat too close to eachother and it remains the same after taking them out and trying to put them back. I have also gotten myself slightly confused so if anyone has a guide on how to install pads that would be amazing.

Sorry for the constant question haha

Thanks so much, I managed to figure it out but Now I'm dealing with my own front brake problems haha

Merry Christmas all, I've run into a problem with my 99' dtr where after taking my front wheel off I've gone to put it back on and I feel that I'm missing a spacer as there is a gap between the Speedo drive and the fork.

If anyone has info on what I should have or what's wrong that would be greatly appreciated

Thanks in advance

Hey all, I have a 99' dtr and I'm new to 2 strokes in general. I was wondering if there is a need for all the small boxes along the air tube as it don't help when working on the bike haha

hello all I recently installed an LED tail tidy and a brighter main bulb onto my 99' dtr the isue I am having is that when using the high beam my power valve doesn't seem to open. I have a feeling that it is due to the load on the battery with the new parts but I am no to sure any help would be very welcome, thank you.

addons I have :

. 12v 100/80w main bulb

. Oxford hot grips ( although they where not turned on when I experienced the problem)

.LED tail tidy and LED rear indicator with resistors in place

@HOTSHOT-III thanks for the advice, the bulb arrived today and what a difference!! it works amazingly
