DT 125 R '88... New project
-
@jgr72 The Athena kits are a bit lack luster, however they will give you more torque.
Yeah sorry they would, but you said you wanted to keep it original. But now you're saying Athena big bore so now I'm confused.
If you're keeping it original, just leave it as is. Otherwise grab a DEP pipe as they are the most performant. That would probably suffice to be honest. If you really need more torque then upping the displacement would do, although I'd be more inclined to grab a DT200R or something similar.

Isn't DT200R engine totally different than DR125R? To be honest, I was looking for KMX200 / DT200, but those are so rare here in Finland... I used to have XT600 many years ago, but it was quite heavy for me...
Well, I might not be so good to express myself
I wan't to keep it look a like original... including that black exhaust and "heat cover" on it. Pipe it self could be something else, if it look near original... No plates etc...What pipe would give more torque? And to be like "4-stroke like" torque?

Thanks
photos will lie, it's not that good looking IRL, but best that i've have seen for some time... there are some scratses in plastics etc...Today, I changed fork boots (progrip, I order them from ebay.co.uk), it was an easy job... Few days ago I changed brake and cluth lever blades, brake was missing the ball on the outer end, and both was wrong color, they should be black and thet ware aluminium-color...
Next step is to find where it's leaking oil... at least 2t oil tank is leaking, If I'm not able to find new hoses I think I will empty the tank and add oil into the gasoline, and forget the original 2t oil supply system...

Okey you did it that way
Today I struggle with front brake pads... I've seen and changed various brake parts in various vehicles, and never been so hard... I don't know did I do something wrong or am I just stupid
But now it's there... Maybe pad retaining spring wasn't in original shape anymore... I need to take it apart again, cause caliper seals ware so bad condition... Next step is to change rear tyre 
-
Few days ago I changed original snorkel to an DT230 Lanza version... Few decals arrived also from ebay... Not changing them now... later... maybe during winter... If I decide to take the bike in parts and do some painting to body and rear swing...
Been sitting in google for hours and days
... searching for something fun:
maybe I will change Gianelli exhaust, Athena 170cc cyl kit and mikuni TM30 carburetor during winter... Those shoud give me more pleasure to ride And still keep original look... Need to work hard to make the money for that -
A little update... Today I fixed front brake... Sealing was worn, and it would be only matter of time, when the brake cylinder would stuck totally... It was already a bit lazy I think... I did it just in time, there ware some corrosion in brake caliper, but I used sand paper and decide that it's still useful... Piston was in excellent condition... Old brake fluid was quite black and shitty... perhaps original and nearly 30 years old? Then caliper rebuild with new sealing and gasket... Tomorrow I have to bleed air away from the system... It looks like I have to use pressured air to force brake fluid into caliper... Brake lever is now doing nothing
Sorry that I was too lazy to take any photos...I found myself from ordering a new carb... Mikuni TM30... and it's on the way already
And earlier I also ordered DT230 Lanza version of carburetor -> air box joint... Lanza item should be direct fit to TM30 carb and maybe some minor modification to the original air box... On the engine side, the diameter difference (VM28 vs TM30) is only 1mm bigger, I assume it will fit to the original intake rubber... TM30 is also 5mm longer, but that shouldn't be any problem...Anyone have idea for right main jet? 160? 170? 180?
Silocone tubes arrived yesterday, I will replace all 2-stroke oil feed tubes from oiltank, to carb...
