UHV 4

Couple more things:

1. The back of the head obviously needed to be covered in. So printed a cover plate.



2. What does UHV stand for? Well, my oldest brother had a Morris 8/40 and it was a side valve = SV. Then my old man got a Holden and it was an overhead valve = OHV. Then this thing comes along and, as the valve is under the head = UHV.

So far all you have seen is words and pics, no generous graphs or proof that it works. So, the moment you have all been waiting for…

As you can see, this was some time ago, so with some more running, playing, changes etc after this, there is more to come…

[F5 Dave]

Well neither of you are fatties. That's some attractive shins right there.

Ha, ha..an absolutely superb observation Dave...

Actually it was cold that day, around 39 deg, so we hade to wear our longies....you would have seen more if it got to be well over 40 though....

What HP you start whit Tim (std .bike )

Black curve: Standard '17 125SX, measured in Gear4

Blue curve: Standart airfilter, OEM Exhaustpipe, Standart jets, OEM ignition, cylinder raised by 0.45mm, same squish, Gear5
Pink curve: Modified airbox cover, HGS Factory pipe, Standart jets, Ignitech with OEM curve, cylinder+0.45mm and slightly ported, same squish, Gear5
Red curve: Same setup as pink curve, but with the Ignitech setup to Overrev #8R curve (see page before)
Magenta: Same as Red curve but with slighly leaner jets

Fun story: The bloke that has ridden it in the european mastership (am not allowed to tell his name) went from his training bike (Bog standard '16 125SX) to the red-curve setup. He thought, breaking at the same point as with his training bike would do the job. In his first lap he flew out of a corner :-D

I would have loved to do more on the bike. I am confident that I would have been able to gain even more power and powerband (other head insert, propper jetting, leaving the ignitech on the bike and adjusting it with a TPS carb with electrical PJ, own pipe...).

Oke Tim

Here only different pipe's

Green is HGS factory pipe

Looking out for Wobb his Pipe design in the sim

[F5 Dave]

Ahh, chance for question: only run ignitech on road race push start bikes with a capacitor or roadbike with battery. Always wondered if you could kickstart a bike with capacitor driven Ignitech setup? Answering my own question I seen CR250 kits so just be ok. Do they start harder? Or pretty much the same?

[wobbly]

When I first used Ignitech you had to have a battery , or no start.
I asked them to change the firmware so that the gradual rise in available voltage from a capacitor storage system would allow it to be push started.I think 6V is the threashold.
All DC DC CDI Ignitechs now have this built in.

Anyway thanks guys for the ignition info - are the two dyno printouts showing Rear Wheel Hp.
Looks like 40 Hp is the bench mark for fairly minor mods with a reasonable pipe.
I am working now on getting the sim to be close to replicating reality , and will then go to town on the ports/pipe/ignition.

[F5 Dave]

Thanks Wob. Gives me options if GasGas CDI gives out.

Ha! And for the ignition Rain setting which apparently is only like a 3* retardation, the rain switch could ground the knocksensor port to do the same thing.

If I had the spare I should put one on the shelf.

My curve is backwheel hp.
But I think with increased CR, a nicer head design and a propper jettet carb the 44hp are in plain sight.

To get a sim for the ktm is a Hell of a job

There are so many things in the engine that are so wrong

Got it now

Al the pipe's ( not the red / green one ) in the dyno grafiek are made in the sim and tested on the dyno ( backwheel HP )

[Tim Ey]

Like what?

Yes. Totally congratulations........

[archie-no2]

Ahh, ok it's a racebike. That wasn't clear


I replaced my older zeel with ignitech just easy. (Old zeel on shelf if keen)

Mine as it came had TZR reedblocks and PWK28s. Massive improvement over std setup.

You'll need to rebuild the crank with decent stuff if you want to rev higher. You can buy stroked cranks of various quality (research) . It isnt a bad idea as it gets you closer to square which brings benefits beyond just the cc increase.

I sold my Toomey pipes to Sam down in chch, I don't think he ever got around to putting them on. There will be much better pipes but depends upon the budget. Managed 70hp so they aren't total dross.

Any chance you have a rz350 zeel cdi still?

[F5 Dave]

Every chance. I'll send you a PM
