230 conversion

I finally received the engine today! Started test-fitting it in a spare DTR frame, and there is a issue with the starter 'features' hitting the frame under the flywheel. I also started replacing the stator, as I'm going to run it with Zeel, so needs a charging coil as mentioned before.
This will take some time, plan is to measure up the engine completely and get it into EngMod2T simulation software first. So, I need to lift the top end, and probably I will do some cleaning of the ports and modify the head, as they seem to be very low compression from factory. I will need to sim the engine to get an idea of what way to go with the exhaust, modify an Athena exhaust, modify a gasgas 250 exhaust I have, or something else.. That way I can enter the exhaust dimensions and simulate them before cutting and welding etc. -
It has the kick starter shaft too, so I can just fit that if I want, but I want the electric starter.
The bushing for the mount under the swing arm is abt 1mm too long, so I had to grind off abt 0,5mm on each side of that one.
The intake has an enormous mounting diameter for the carb, so I ordered both a Cr125 and (hopefully) a smaller version of the DT230 intake. CR125 VF4 drops straight in, but might obscure the boost port too much. I have no plan to run e mega carb. I think 30-34mm should be enough.
I have taken off the cylinder now, and will measure the engine and simulate it in EngMod2T later on.
Expect no pictures here, because I don't use the image hosting services that go away, ransom your pictures etc.. (if you know, you know). I did put up some pictures in the Swedish DT125 FB-group. -

That said, I have migrated my images to the server so that the issue of images being ransomed goes away for me.
Oh that's really awesome. I certainly hope it works out for you though. I think I'm done with the DTR platform for the time being and am concerned with my RD at the moment. But I am building an LC motor which one day may be transplanted into a DTR chassis...

Hard to get tuning parts for the LC engines though! I have a modified Athena 170 on a DT LC engine, It was all I could think of. Welded on a reed inlet on the cylinder to get a cylinder reed. Had to send it for re-plating after that, because it was warped during welding. Runs about the same as the DTR which also has the Athena 170 for now (until I transplant the 230 engine). It's a custom build DT LC 'supermoto style' with a low slung exhaust and 18" wheels front and rear. Yamaha competition yellow with some DYI side fairings and graphics. I named it DTX. Put a lot of work (and money) on that one this winter!

Not sure if this will work: https://www.facebook.com/photo/?fbid=10165850989140701&set=g.1650331705410143

As a swede who recently have ogled DT200's and Lanzas for sale in Greece, pondering if a trip down with a small lorry is too big a venture, I find this HIGHLY interesting. Please keep us updated!

Join the 'Yamaha DT125 Sverige' FB group, I try to update my post with some pictures from time to time. Plan is to get it running before the end of my vacation, in two weeks.

Yeah, thanks - I used to be in that group but dumped my Facebook account this winter.

By the way - this seems to be the most frequented site for looking at DT200/230 bikes and parts in Greece. I am not sure, but I think it was the only market in EU where they were sold.
