Hi DR fellas,

my name is Koen, I am from Belgium. I really love the DR family but never owned one of my own, i've ridden a 750, almost bought an 800 and now found a beautifull DR650... Last week i had a chance to ride it, and i really like the experience, the design, the position, well almost everything :-) But! It is a DR650SEU, imported from Germany, so it is restricted to 25kW... And indeed while riding it felt a bit underpowered. So now, before buying it, i would really like to know if it is easy to de-restrict this model? Thank you very much!

I'm not sure exactly what was done to restrict them, but it might have something to do with this

Did a quick check of the carb parts and the slide and needle jet for your model have a different part number than the non German models.

You might have better luck asking about it on this German DR650 forum:

Good Luck!

hi rowie,

thanks for your input, it certainly looks like that air hose is somehow restricted.
I've also read that there's some plastic piece in the carb that should be removed. That would explain the non-stock needle and slide...
Good idea also that german forum, hopefully someone speaks english over there :-)

I asked a question (in English, with German translation) about something when I started the restoration of my '90 RS and the replies were in English. You should receive a reply, or search the forum in Google Translate, and you may find an answer.

Cheers!

I couldn't say specifically what's been done to restrict your bike, but it's usually done with an intake restriction (narrowing the intake), a throttle stop, or less likely in this case, an ignition limiter. Probably it's just a metal plate that's easy to remove, along with changed jets.

The Secondary Air Systems is an emissions controlling device that let's fresh air into the exhaust port, thereby increasing combustion of unburnt exhaust gasses. It's got nothing to do with power limiting.

I have send an email to Wolfgang from Tigerparts.de as he is selling DR parts and lives in Germany.
He says the U models are normally restricted by a plastic can in the carb. Just removing it and put in stock jets and needle should do the trick!
When i have an afternoon of spare time for some carb surgery i will certainly make some pics.

Thank ya all for the help!
