    Motul motocool expert (yellow) and Aisin coolant for motorcycles (blue)
    I prefer Motul because it's the best I tried,has the least fluctuations in the temp during usage.A little expensive 10 euros per liter.Normal riding city or cruising 65-75c temp,on the high side 87-90c when going up the mountain through steep bad fire roads.
    Second one is the Aisin,similar performance, normal riding city or cruising 65-79c and up to 95c on the fire roads.5L for 21 euros.
    All these on Greek hot summer evenings,34-38c.
    Currently filled with Aisin because I had 3 liters left and doing some work on the bike.

    I see you also recomended me the Zeeltronic. I'll make some research about it. The main problem for this bike at least in Spain (where I'm from) is that there's not really any market for it, and it's a shame really. I saw the carburetor as the "accesible small powering piece".

    I just dont want to change the cylinder or big things like that, just a small thing to change the performance of the bike without going for too much, just a little push. If Mikuni is good brand then i'll search for a 32 Mikuni to keep the line of being always equiped with Mikuni.

    I bought the bike with a Gianelli exhaust with homologation. I see almost every DT with installed Arrow, DEP, Turbokit or Gianelli exhausts kits. It's the only aftermarket thing installed to it.

    Now before changing carburetor or anything else, I need to fix the regulator, alternator and battery, and then i'll see.

    I see you're also pretty close with the bike, and very aknowledged about it. I really aprecciate the advice you're giving me.

    It's probably fine. I'd just do a compression test make sure it's within tolerance and schedule in a top end refresh if you don't know when it was last done. Generally though, the DTR is a pretty strong engine so it's damn reliable.

    Frame looks same bottom end on tht looks like the dtr engine I have my 4hw has no cover over the oil pump and has some kind of make shift bracket for the oil cable. Looks like they chopped my frame and put a heavy duty swingarm on for that 4DL raised the coolant tank and put bat under the seat. Thats why I asked cause surely the 4 wires from the engine are the same or do I have to change the flywheel coil bit of forget its name now. I think i'll give it a bash as I got to remove the engine anyway if the mountings are the same and it wires up maybe I can put a DT rear sprocket on.

    Food for thought ive got to get the energy to get at it first i'll look over that cdi wiring diagrams thing you shared and go from there just hope the exhaust mounts dont throw it out of whack.

    I'm hands on so once got all the parts in sight i'll hopefully make sense of it all feel free to leave suggestions etc like I said before wish I had someone here to help me out going to be fun though so hopefully will give me more incentive.

    @HOTSHOT-III Interesting bike that Aprilia,never seen one before.
    A DT could transform into something similar,twin headlights, modified bigger tank, keep it's enduro costume.

    @Calum I would grab a tig/mig and extensively repair the frame. But I am known to see hope/light in garbage stuff with a lot of time and work coming back to life.
    Example. I was offered an XT500 with low km's but sea salt corrosion damage to the frame,not passing "MOT" here.Very low money,but I have no time....for now waits to the owner garage until I find time.
