Maybe the green and white wire from the speedometer is disconnected. Usually the engine stops at 6.500 rpm it is possible that the revmeter shows a bit more and it looks like 7.000 rpm.

Tomorrow I will check that.

But as I heard with that restriction bike only stops in 6 gear when reaches 80 km/h?

My stops at every gear.

Here is video of my bike performing 0-100:

if the green-white wire ist cut or disconetet the CDI goes in a emergency-programm an the engine stops at 6.500 in every gear.

I looked this morning for that wire and everything seems fine.

Can you tell me where can be restrictions of my model?

I removed the cone from the enter to the exhaust, and adjusted the valve (i moved it for about 10 degrees counter clockwise), what else can be?

Can I fit this CDI from the DT, it have same number of connections as mine:

Ok, thanks!

Then I will need to buy this one:

that is the same cdi like yours. You only need this one if your CDI is broken.

This is the open one, and this revs freely to 10k rpm, that is what seller is told to me.

yes and in your tdr is an open one too, because the cdi with 5AN on it is open und the cdi with 5AN1 is restricted. A restricted CDI stops only at 80km/h not hat 7.000 rpm in every gear.

So something must be damaged oder changed. For example maybe some has changed the carburetor, the engine has not enough Compression or the CDI is broken.
