How quick should a dt be?

@DevonDtr Yeah I think that's all the restrictions that are on that model and once there all taken care of and you re-jet the carb you'll gain some more power! You could also try playing around with the sprocket sizes to get more top end out the bike by going up a few teeth on the front sprocket and down some on the rear and I hear changing the CDI makes a huge difference on these bikes and is the best money you can spend to gain more power so if your unhappy definitely look into those basic mods first

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.

@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

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.
. Has your friends bike got any mods done to it as I'd imagine your bike should still be quicker than a 125 4/
