I'am looking for bigger valves. 1 mm more than the original's.
Where to order or (better order nr.)

Gonna chance in and outlet channel, and have to change valve seat's.
They make a new profile at the valve's, and that's why they have to be a mm bigger Very Happy

1 of the Visa valves is a few mm bigger than 2cv valves, don't know whether that is the inlet or outlet valve.
Otherwise try Geoff Archer from http://www.2cv-speed-shop.co.uk/

Good luck, Bart

go to the website of mahle automotive, you will find a search engine for valves.

having said that , if you are going just 1 mm bigger , i wouldnt bother.
with such small a difference the improvement will be minimal.
2cv engine are hardly restricted bij their valves anyway.

Not so simple, to find other valves Confused

But we used the stanard valves, and reshaped the valve seat of the inlet valve.

In theorie the inlet valve could be c.a. 2.5 mm bigger than original...

Now just changed the flow.

I'll want to hear it running.....

Why is there alway's a lack of time Sad

O yes, They call it work...

Very Happy works great, but not for home use Twisted Evil
