    Getting use to this forum again it’s becoming like a daily blog to me 😅

    I’ve got some of this really nice braided mesh loom stuff I decided to do away with the plastic rubbish on the switch gear and replace with this I think it’s a much improvement

    What do you guys think ?

    Will be doing most of the wiring with this when I get round to it

    Also has anyone done much to to make the switch gear plastics look better only thing I can think of really is just plastic polish

    (Obviously photos don’t show it as well)

      @mhbikesnbits yes I really like that. Where can I get some from or what is it called? Also does it go over the plastic or did you strip the plastic sleeve first?

            @mhbikesnbits Looks smart, is it designed for motorbike looms? Does it wick away water from the loom? I'd be worried if it saturates water and retains it.

            Looks smart though.

                Added this for a little protection where the triple clamp hits the frame

                alt text

                Picked up a dt200r alloy swing arm from Australia should be a nice edition, bit lighter weight and going look nice once I’ve done the lovely task of polishing and shining up

                Also got offered some discount on a all balls bearing kit £35 for the restoration of the swing arm, not bad can also take the sizes and look at building my own kits to sell along with the suspension arm joint bearing and seal kit.

                      Sorry for the lack of updates been busy with some other stuff, not really done much to the bike, come to the stage where I need some parts, The alloy swinger is here looking forward to getting it shined up should look the part on the bike.

                      This is my next task get this cleaned and polished was curious about the weight difference in this and a 125 steel one turns out it’s between 700-800 grams lighter according to my scales

                        @mhbikesnbits Not a HUGE weight saving...but replace the bolts with Titanium and what not and you could be laughing.

                        I replaced the front engine mount with a titanium bolt and that's a good few gs saved. All adds up.

                          @Calum you know you lift a steel one up and then the aluminium one and it feels so much lighter , I was surprised myself it was only that much different unless the scales lie 😅

                          Should save little more weight swapping from steel rims to alloy too and some other bits here and there maybe, we shall see

                          Titanium stuff has crossed my mind

                                @mhbikesnbits I’m In Talks with a guy in Australia who owns a 200r give me some really nice info on it and it’s general handling and stuff.

                                He also has a load of parts and I’ve got all the important parts for the engine I need, the loom, cdi , servo all the electronics, the split pipe for the radiator and saving me a load of parts for the future spares ect I might need.

                                Really big step forward to completion as it could have been months before I found these bits for sale

                                  @mhbikesnbits Yeah I would love to shave off as much weight as possible on my DTR.

                                  Another good one is to grab a lithium battery. That's a tremendous amount of weight saved!

                                    Firstly this is an amazing build and coming together well; I'm only sorry I didn't pay attention from the beginning as I now have lots of catching up to do!!

                                    Very interesting to look at pics of the combustion chamber; the squish band is huge and has to occupy around 75% of combustion chamber area as an estimate. Just had a read of the cylinder head chapter of A. Graham Bell's two-stroke tuning book and this puts the combustion chamber design in racing kart engine territory. Apparently kart heads are like this because they're heavily loaded pulling out of slow corners and this boosts torque and reduces the possibility of detonation but does sacrifice some top-end power (on the other hand road race engines can run very thin squish bands to be more efficient at high rpm).

                                    This could mean (subject to other critical engine dimensions) the DT200R 3ET develops a very linear power delivery similar to KDX200s and stuff like that, just what you need for enduro/greenlaning. Thanks for posting up the pics, the DT200R is so rare in the UK I've never had the chance to look at one before!

                                      @mhbikesnbits said in My DT125 80s Yz style DT200 build one to watch!:

                                      More work to the engine barrel and head cleaned every engine component now finished cleaned ready for powder coat

                                      @HOTSHOT-III thanks for kind words about the build, I have read before the 200r engine has plenty of low down torque, pretty popular for the green leaning and enduro too wonder what Yamahas idea was for the design especially for it only been targeted towards certain country’s

                                        @mhbikesnbits Yeah I would love to shave off as much weight as possible on my DTR.

                                        Another good one is to grab a lithium battery. That's a tremendous amount of weight saved!

                                        @Calum dam like the ideas , titanium bolts and lithium battery , really good ideas makes the wallet more empty tho 😂

                                          All the important bits for the project are here loom , cdi , sevo and the other electrical goodies,

                                          Also the split pipe got some more work to do now ,l it’s mounting up
