    @Calum Just to butt in a sec,

    I've noticed my Flickr links are not embedded anymore, and wont do so..

    I will have to go through and re link every one from a different hosting site?

    @Darty No they probably just need embedding properly.

      Got a few small but satisfying jobs to do.

      Fit the 17t front sprocket to gear up.

      Fit stronger clutch springs (uprated wr200 ones)

      Coolant and oil change.

      Custom thicker core alloy radiator.

      Replace LH crank case cover with a silver one to match.

      General fine tune and visual tweeks.

      I have it on the bench next to a standard one with a spare sub frame bracket. Bottom hose connector needs repositioning. Mounting brackets need welding on and also for the guard

        Starting the fabrication, sits very nicely in the sub frame. Removed hose connections and prepped new ones to be welded on (and weld the big hole)

        Then I'll fabricate new brackets to take the old rubber mounts. Also checked the clearance for when it's on the bike. Should be plenty room before hits the fuel tank.

        Fabricated the two mounting brackets. Jigged it up using the subframe to ensure it's not going to rub. It will be free floating on the rubber mounts as it should.

          @Louis-James This ought to make a nice difference in cooling!

          Just for anyone else wondering a single ally rad is going to be much more performant than twin iron rads.

          Just have to be careful not to cool the engine by too much else you'll heat seize the engine on long runs.

            Hopefully @Calum, still was running alright on my standard radiator for the wr200 motor even though it has 2 as standard.

            What do you mean by iron? Who would fit that? Would be heavy as.

              @Louis-James Stock brass or steel or whatever the original radiators are made from. I know on cars they tend to be brass.
              On the Starlets you can get way with running a radiator half the size if it's an ally one as it dissapates heat so much better.

                Also to note, this core may be 10mm shorter but has 11 cooling tubes and not 8. Also 20mm thicker

                            This has gotta be one of the best DTR's I've seen! Absolutely stunning mate 👌 A load of great work here. Have you had it on a dyno?
                            I didn't realise until I looked back through the thread that I bought your old tank panels off of eBay last year. Still look good, although the RH one is now Drift Stitched from a bad knock 😂

                                Ohh my insurance policy came today.
                                Since I've invested so much time and money into this bike, I bought a spare heart!
                                Because the cylinder it has now is 22 years old on standard size, as it is nickasil plated.
                                The new one is also plated and honed.

                                      @Louis-James That's actually really cheap.

                                      Yes you are right Louis, however there will always be better engines to transplant should that be the case.

                                      Hell even electric engines are far superior to most petrol motors/.

                                        @Calum almost worth making a whole new engine haha, I like the idea of a yz250 evolution 88 motor, don't fancy chopping the frame though. Maybe I'll get the bike one-day

                                          Got some work done.

                                          Replaced the clutch springs for the uprated wr200 version (15% stiffer than stock WR) they are actually longer, but that's one way to make the sprung force stronger.

                                          Oil and Coolant change, replaced the 2t to manifold hose for another clear one as it has gotten cloudy.

                                          Polished the exhaust and detail cleaned the underside of the engine in every nook and cranny that was left from rain riding haha.

                                          Straightend up the rear silencer as it was aiming to my number plate and getting lots of gank on it.
                                          And resealed the slip on part on the downpipe (I hate slip on!)
                                          Got a new fuel tap to fit when the radiators welded up, I'll do it together.

                                          A few new visual mods I'm toying with are to come (make it more original trail look)
