Gianellis dyno reading on their perfromance exhaust for the DT

Pretty much everything that you can do Nordt, the list is as long as your arm mate, but still a 125cc, well 135 point something cc it is since the re-bore.

Aye bike was getting full power but stopping on me every now and then

chap I take it to for any intricate work, took it out for a run the other day worked out it was the barrel, I thought it was the carb, other than that, he's happy with low end throttle, mid range I need the needle raising a notch and top end is spot on.

1937_Yamaha DT125 RE-X x sito.jpgAbout 25 bhp. Thats pretty nice i think.

 

Found this on gianellis own site http://www.giannelli.com/eng/prodotti/details_pro.asp?id=562

You need to get your own bike on the Dyno Nordt, I'd like to see how that would come out.

Hehe, Norfe. ive been wanting to put my bike on the dyno too sometime. But i have no idea where to do it or how much it would cost. I heard they can do it in a city about 100 km away from where i live.

Aye well now I know why mine kept bogging down and stalling on me, its being sorted out this week, needs a honing out as it was too tight for the piston expanding when getting hot, just hope I haven't got to go through the ball ache of running it in again, but deffo banging it on a Dyno when its all ready,

Do you have a project post or something about it ?.

You got the barrel ported too ?

Is it wild ?. i got a spare engine i wanna try out some stuff on. porting and other tuning. Just to see how fast i can get the standard barrel.

Aye theres a project thread on here, but the one on my signature is a more detailed one, on another forum. yes the barrels ported and gas flowed, but needs honing out a tad more, as its not allowing for the piston expanding when getting hot. I was getting full power, but it would bog down and sometimes stall, bang it into neutral, and it would kick up again straight away, but do the same thing again further down the road, I thought it was carb problems, so took it to my chap who does all intricate work on it to see if he could set it up right for me, he took it out for a run to see what he thought it might be, found it to be the piston semi-siezing in the barrel. so thats being sorted this week, low range throttle he reckons is good, mid range throttle the needle needs raising, top end is spot on.

No idea, DEP works for me though. Be interesting to see the pipe of choice the Portuguese or the Balkan lads use on their DT's mind.

Lol ^

The portugeezers use a front pipe called the firebox, i've been tempted to get one just for the difference and i'm pretty damn sure the front pipe phillipe sells in chrome is the firebox pipe.

Looks pretty much like a DEP to me does that, tell ya what though, for a production pipe the welding looks a bit ****e.

Hmm, that graph shows the max power a lot higher in the rev range than where mine is, runs out of steam at 8k. Gonna have to see if I can find a derestricted cdi I think, good 5 bhp to be had there lol.
