    Thanks but I put 200 not 250 although I do know that SM has built many Yamaha's over the years and he had a WR200 and WR250Z when I had my first DT200WR so appreciate his detailed and extensive knowledge - just need him to magic up some DT200R engines 🙂

      I did see you put 200, but I'm not familiar with that model. Rarity may be against you, the 250's are easier had.

      You not what I wouldn't mind?

        Sorry I wasnt being funny 🙂 just talking about making my own home built 200 like Yamaha could have built

        Yes the SDR200 - rare and expensive now and oddly with a different engine to both the 3XP and 3ET 200's - looks like its based on the old 200LC motor.

          I don't know if they are rare. They were not sold over here which is why we don't see them. Sold in Asia. And yes it is of the LC age, late LC 1988.

          I don't know though, there is something I just like about them.

            Yes they look good - kind of a merger between an RD125lc and a TZR125 but with a nicer looking frame

            Only ones I've seen lately are all going for £3k+ right now so definitely look like people want them to command such high prices

              @Calum i not long ago passed up the opportunity to buy a full 89 sdr engine because I want sure how I’d go about using it. I’m gutted now. They didn’t want much either.

                @Stevie-Wonder they claim to be a Conservative 34hp which would be nice.

                I don't think 3k is too bad especially as you see people wanting 3k for an Aprilia

                  @Calum 34 would be nice. About the same as a WR200. It’s also worth mentioning that the SDR200 bottom end doesn’t bolt in like the others and I’m not even sure top ends are interchangeable. I couldn’t find any info on here about that

                      @Calum * just to update what I was saying. I just remembered who it was I was talking to and it was a couple of the TZR Belgarda boys. He says the lower mount of it is all wrong and because of the electrical start it makes the SDR motors very ideal and highly sought after by them as a direct engine swap. Unfortunately not much good for us though

                          Yes only the WR / R motors are a direct swap - think the SDR has an extra rear mount but I've never seen one in the flesh for maybe 20 years now.

                          £3k isn't much I know especially as they wont lose any value

                            @Nottsbiker yes it does, it’s what the Belgarda boys where telling me as I had asked if they where using that motor whey they’d never used the 3XP. Also update
                            I now have a full 4FU. valve head and barrel.
                            I still have the P but that’ll get sold to fund the 4FU. Unfortunately the guy with the 170 never got back to me so I set my self a challenge of finding a 4FU valve in under a day by the evening.

                            Looking forward to the day I run it and it seizes, nicasil liners and the extra rebuild cost is what initially stopped me going anywhere near I kmx and now here I am 😂 Do you think I’ll sacrifice much reliability with the 4FU?

                                Nikasil plating is fine. There is no compromise in reliability? Why would there be?

                                The tolerances can be made tighter. There is greater heat transfer between the engine and the coolant, meaning you can push the engine harder for longer.

                                  @Calum sure but in the event of damage usually it means it's screwed and it's pricier to replace obviously it's better but like I said it's not for me

                                        Okay that makes a lot of sense. When you put aside the fact a seize or something could cost you very dearly on paper they actually offer a lot more quality’s. Not to mention the sound lol.

                                          @Stevie-Wonder it's not that much more expensive is it?
