    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.

    Getting there...

    I am pretty happy with the design, I just need to modify where the holes go as there is that gap at the bottom I want to close up. It may just be easier to drill the holes myself.

    I've got a quick print going now and I'll drill the holes myself and then remeasure it and do one final print. If that still comes out wrong then I'll just drill the hole myself.

    Ideally it would all be part of the CAD so at least if, for whatever reason, I need another one, then it would be simple enough to sort out.

    New rear disc ordered as mine is warped. Need a fresh set of tyres on this rude boy too. These are coming up for 10 years old now...wow 10 years 😮 scary to think.

    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.

    Cheers @HOTSHOT-III. No me neither, but there seems to be some sort of cult following for this specific bike.

    That's the saddle and they want £110 USED.

    And the single speed frames seem to command decent money on the used market.

    This one here is for £600!

    Few teething issues just snagging the bike yesterday morning and then went to go ride the bike and came back to a flat tyre. Not sure if it was a defective inner tube as the puncture repair kit just melted the inner tube.

    So I've ordered some more inner tubes and if I can be bothered could cycle over to Halfrauds and buy one so I can use it today.

    The floating parts of the disc were fouling the bike/caliper so some minor adjustments needed and setting the chain tension etc. But it's basically there. Went around the block and I probably need to drop a few teeth on the front chain ring as I won't be doing any uphill cycling with it as it is. Fast on the flat though 😛
