Dt170 vs ktm exc 125

@calum what’s preventing my am6 engine from reaching say cr80 performance say I put a cr80 head on there magicaly get the crank to fit with the carb etc would it essentially be nearly as fast as one like what’s the limiting factors apart from fitment of Honda parts

@declan Cylinder wall thickness I expect. Only so much porting you can do.
You could get the DT to be like a YZ. Just needs blue printing.

@declan I'm saying with lots of cash you could achieve anything. But it's pointless at this point as you may as well have bought a better engine.

I think they're really versatile. Loads of tuning bikes, were used competitively yet have all the features to make them tame for the road. Can be tuned very well, and take lots of power.

wrote on 30 Oct 2017, 22:39 last edited by@irongamer727 That sound is obviously deeper being a 170, but it sounds similar to my Romeu Hendriques system? but ofcourse its alot quieter on my bike haha, I had an old style circular Dep silencer a while ago on my DT and it was very loud and sounded "poppy" like that 170, im pretty sure it had no or very little packing in it haha.
This is a clip of my bike, sounds better in real life mind

@Irongamer727 No exhaust stuffing is actually counter productive,
but, Induction plays an important role in the exhaust note.
Mine sounds really good.

I am always confused as to how any air is sucked in with the air box and snorkel system? To me is looks to be pointing in the wrong direction and I always feel that the rider and seat will reduce airflow around that area too. But I guess it is not too restrictive as all bikes perform extremely well with the air box and snorkel set-up. Has anyone tried small air scoops on the side of the air box to draw air into the box at all ???
