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

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?

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? ...

But how bike goes well until the 7k and then suddenly stops.

If i have the smaller main jet then the airbox also would be restricted somewhere.

Here is video of my ride, and there clearly you can see, that it gives it best at 7k.


Sorry on bad quality

OK! I will do that, but I'm not optimistic that this would improve anything. In the low RPM bike goes really great, and also you fell how it open's valve at the 5 and full at 6.5k RPM, and then suddenly stops at 7K. It isn't problem in the valve, because one time i was put the valve in open position...

Where I shall look next?

In the valve isn't problem, because i removed the exhaust and adjusted it with my finger.

Also problem isn't in the silencer, because I taken the ride without it.

Also I was cut the exhaust and there wasn't any restriction.

I looked on my CDI, and on it is written 5AN.

Also I found on ebay, this item:

Do you know, can this derestrict my TDR?

Thanks!

YPVS was the first thing what I was checked.

I removed the exhaust, and the turn the contact on, and the using my finger aligned valve.

As I heard my bike have the restriction on the revs which moves spark angle when bike reach 7k rpm.

Before one month ago when I was removed the tank, as I can remember there only was the black cdi box.

Is it possible that restriction is in the CDI?

Are you kidding me, this bike should go at least 130.

In other gears it also gives its max at about 7-7.5k rpm.

I heard that I need to ground black/blue wire coming out of the cdi, but I don't know is this for my model and also where do I need to cut it?

Hi! First of all, sorry on English, but problem is that I'm from Croatia and don't know German. I have Yamaha TDR 125 2000 year which is bought in Germany and I want to derestrict it. I looked everywhere but nobody knows so you are my last chance because this bike is from Germany so I supose that so...
