How quick should a dt be?

Hmm weird! I know a few people with 125 4/ bikes and they can't get close to my bike although one friend has a Yamaha wr125 supermoto that's been fitted with a big bore kit and some other mods and that will keep up with my DT but accelation wise my bike destroys it lol must be because my bikes older 1997 it's full power it will happily sit behind my cousins YZ 125 and acceleration wise it isn't far behind it

It should piss all over the yzf r125.
You're confusing.
You say its got a dep and a big one full system.
Which is it. You can't have both.
You either have a big one full system.
Or a dep.
Or do you mean you have a big one expansion chamber and a dep end can.
Even as stock the dt should destroy the r125. I remember kids around me having one back in the day. Unless they got a whole lot faster!
The DT isn't a pocket rocket though. They are just an all round good two stroke. Get something like an rs that will make 250 four strokes look silly.

Yeah I wanted an fmf full system but they are Mega bucks. Next month she in again for another batch of goodies so hopefully I will see better performance

@DevonDtr I've been looking into exhaust systems for a DTR SM project I'm currently building up at the moment but it seems the FMF system isn't official from what I've been reading. A ktm 125 FMF system can be made to fit the dt's with some modification there's a few videos on YouTube with dt's using them.
Every problem has a solution

@Biker_123 makes sense. KTM did a model with dtr engine in. So would make sense a pipe exists for it.

I got a yam dealer close so I will pop in and ask
is it a massive differenc for the price?As I keep saying.
In my experience it is THE BEST bang for buck.
The power is increased throughout the rev range. The torques are massively noticeable. The peak power not so much.
Bare this is mind, any thing else you do to the engine will be multiplied when you run an aftermarket ECU.
I have had barrels ported, exhausts, Carbs, different rare "super teen" engine, and the one thing that stood above the rest was the CDI
Always Originate, Never Pirate!

@tdrgreg2 Super teen was a racing series for teenagers to enter. Due to their age and experience, the series was designed to race 125 two strokes.
Teens would predominately race Aprilia RS125's, Honda RS125's and the Occassional Yamaha TZR 125 RR
The engine in that bike is a direct fit into the Yamaha DT125R.
I fitted that into my DT.

Thank-you buddy! Sounds very interesting. Are you currently running the engine on the Leviathan build?
@tdrgreg2 No it was worse than the RE engine lol.
It's all in that build thread.
It's a very special engine, it was an engine cast using motori minerelli stamps, indicating that it was a genuine Italian built engine.
But the casting is week, the cylinder is, well poor and it is in fact the SP you really want. Good luck getting one, it would be easier and cheaper to run another 125 super teen engine in the DT frame, like oh I don't know the Rotax 122 engine which can be had cheap and tuned better!
Can't find an example of the porting. but it's insane.
Until you look at the rotax engine, which again was mass produced, then you realise you're paying a lot of money for not much really.
. Has your friends bike got any mods done to it as I'd imagine your bike should still be quicker than a 125 4/
