DT 125 R '88... New project

[Irongamer727]

@calum was it really worth changing to a 32mm carb? I mean it's only a 4 mm difference from stock? Thought those 28mm mikuni carbs were well up for the job. I'm still running the 28mm with the 170 kit.

@irongamer727 It's not just the fueling, it's the amount of air you can get in as well. My brother ran a 38mm Keihin carb on his, although to be fair that was probablyt way too big. 32-34 is about right I'd say. The Aprilia RS125 ran 34 as standard and they were making 26-33bhp.

@calum are there any of the aprilia engines that don’t have right hand drive?

[Calum]

@declan Aprilia didn't make their engines. Just swap the swingarm when you do the engine. Simples.

@calum well uno out of the Rotax engines but what if it’s an sm

[Calum]

@declan Just get an mx mate, much better bikes.

Bike is getting ready for next summer:

That exhaust chamber :smiling_face_with_heart-eyes:

Gianelli silencer:

But need to twist something:

I guess it's easier to warm and twist + cat a little bit of that exhaust chamber tail pipe... Gianelli's aluminium would melt away too easily...

[Calum]

Looking lovely, I'd be reluctant to bend the pipe, just make up a larger bracket and move it closer.
