Hi.
Very generic questions,search the forum,a lot of tuning and project threads.
With that info you will have more specific questions of what you want.

ATHENA 170ccYes it worth's the money ported or stock will give you mid range and the ability to cruise at nice speeds around 5K rpm depending the gearing,if you go the tuning way depending the depth of tuning,you can still have mid range like above but scream at about 13K rpm.
Zeeltronic is excellent as @Calum said.
You can "play" nice with Yamaha's CDI from other models if you want or some unrestricted.
@Calum has done extensive mods the other members mentioned from him have their respected history also,I will add @SpookDog and @Louis-DT-WR. -
crank noise@erioni123 Hi. It's not ok,it should spin freely and noiseless. You have to check/replace crankshaft bearings and the bottom big end bearing. I would change them all to be in piece of mind.

Powervalve fully open@OllieDTR said in Powervalve fully open:
I found the 3NC-00 cdi on my 96 French import wicked! revved to the moon and went off the clocks no problem on stock gearing
The same does the 3NC-00 cdi on my 94 German import.

How long does a piston last, really?My DTR had 56000km's on original piston,it had still life in it.
With a fresh set of rings and a fresh honing it could go another 15000km's probably.
Still have it for measurment's and is usable.
Off topic I had a Piaggio Skipper 150 2T,with 95000km's on original piston with nicasil cylinder. -
DTPedia; Anyone Seen This?@Calum That site is known even more year's!!!!!

So Close!...@SpookDog said in So Close!...:
Can anybod link me to somewhere selling AllBalls rear linkage bush/bearing, seal, bolt, repair, ect kit?
I can’t seem to be able to find it…
Had bought everything from Greek official Yamaha dealer with their part numbers.
Doesn't matter if it's old part number,they will sent you the replacement one. Most of the times they have very good prices that you saves you from the hassle of multiple different purchases.
Did you try it at UK? -
DTPedia; Anyone Seen This?I know it for years now,thought that you all knew the site.

engine piston check@erion1 And probably was compromising the oil lubrication properties along the evaporation. And it's not a 4T to have an a lot oil, but even then I wouldn't want to have coolant in my oil.
-
engine piston check@erion1 After you remove the top end,only an experienced one can tell you if it's ok the bottom end at a 90%.
To be sure 100% you have to dismantle the engine.
When rebuilding,changed conrod just in case,because 0f 56k km's of the engine.bearings still had life and the con-rod was so good that a friend with a machinery shop checked for tolerances and told me to keep it for backup with a new set of bearings.
I just couldn't gamble with a top end rebuild of an unknown internals condition.Piston condition was way better than yours,still have it.
You get me what I mean. No video/sound recording can replace that. -
engine piston check@erion1 Have you done a compression test,if something is wrong with the piston or piston rings it should show low compression.

Stevie’s French '98, Mid-90's WR/YZ/DT (An idiotproof guide to building your own DTR)@Stevie-Wonder I am also at the point thinking go back to stock looking bike with a little improvement twist I already have.
Already the alloy 3ET parts are on the bike, now servicing a set of stock DT200 alloy wheels in very good condition for their 30 years old. -
Anyone else think these things are missing a 7th gear?!? - 1992 DTR125, delivered a couple of weeks ago.Nice bike mate!

The Dionysus Project (Aprilia ETX 125 Rotax 122)@Calum When doing work on the frame after stripping the paint,I was washing the frame with acid for 2 hours until no rust was found,then did a good wash with a chemical base diluted water to eliminate the acid.
A good soap water bath and drying up with a butane based torch. Then did the protection steps.
4 years in the weather (no garage) no rust on frame.
Maybe you should DIY at home to know what is done on the frame. -
The Dionysus Project (Aprilia ETX 125 Rotax 122)I think it needs sandblasting,an acid bath and then a zinc coating.
-
Stevie’s French '98, Mid-90's WR/YZ/DT (An idiotproof guide to building your own DTR)It's a sad story with good outcome.
You came out with a solid companion in life (the other half),a beacon of light for the path (the DT) and your health don't underestimate this,trust me.
Hope everything will be better for you. -
So Close!...@SpookDog You can disassemble the cap and clean it.
Somewhere in there is a piece of thin cork,if it's rotten change it with the propper thickness oak paper. -
engine piston check -
gasket identification@erion1 Better get for the DTR a specific gasket set.
The TZR125 2RH head gasket is thicker and designed for the massive head water jacket and a bigger rad that engine has.
The bottom one is thinner at the sides and thinner as material,not a good fit also. -
gasket identification@erion1 Head and base gasket is for TZR125 2RH
