I don't believe I can find all missing parts for the original overly complicated setup. I need the block house and the rubber insert between the reed halves.

The Husqvarna reed block is perfect. I will post updates.

I don't really understand , why don't you use HIRO OEM parts to rebuild the engine?

What do you think of this Husqvarna reed setup?

Thank you Birdy 459

Let's see if I understand correctly?

Yes the piston is flat on KTM, slightly tapered on hiro
2. I can use the contribution and Reed YZ 125 1981-1982 if I remove certain materials from marked
red? yes, the pipe can be fitted without admision big change with the systhéme YES
Have vis the YZ 125 reeds adjustment on the cylinder?

Thank you birdy 459

2. I can use the intake and reed from YZ 125 1981-82 if I remove some material from marked
red?

Do the yz 125 reeds fit bolt on, onto the cylinder?

the piston is a fair price for the valves, YZ 125 1981-82 with the pipe and it takes Hollow out the aluminum to place the box has clapte yz, and make a decoupe the piston the same as on a yz cost admission not Ktm

Hi,
Yes. Lots of great information but a little hard to find since I don't understand French sadly.
Does anyone know if there are sidepanels and seat covers available anywhere?

I also have an issue with the reed valve configuration. I'm missing the entire reed block/house, cage, valves and intake manifold. But I'd like to make a new block with a normal style reed valve instead of the open piston port intake in the middle and reeds to the sides which goes directly to the crank-case and transfer ports. That way I hope to use a KTM 54 mm 125 cc piston with a hole on the intake side for the boost ports.
