        @irongamer727 Do you mean the whistle?

        Looks like it is the problem with the starter, but I think it does not affect the main issue

          Spark plug news

          According manual it looks like it is carbon fouling colour

          Causes

          rich fuel/air mixture (maybe air leek)
          faulty choke (Not sure how to check as it looks all right)
          blocked air filter (probably not)

          Pictures

            @tdrnoob Found a small crack on that rubber, but it looked not too deep.

            I have put some glue.

            Last picture is to compare my one on right and the other one left from DT 125 (had a spare one). It looks like someday my one was modified.

                You will struggle to find anyone willing to post to the uk and the shipping rates are crazy from here.

                Loads of lovely WR200's out here too 😉

                  Loads of 200's in France but most seem to be down south over near to Belgium / Switzerland and I'm currently in the West.

                  WR200's go for anywhere between €1000 and approx €2000.

                  Unfortunately France isn't up to speed with couriers etc and you pay silly money to ship from here to the uk whereas the other way round it's much cheaper.

                  DTR's go for €500 upwards so it's easy to see how Unit 5 Motos (etc) can sell them for £1500 unregistered in the uk by bringing in about 10 every visit.

                  If i was in the market for a tidy WR200 I'd drive over here via the tunnel and buy one in France as the choice is so much better than at home.

                      @tdrnoob first thing I did was removed starter motor to see if its really that problem and it was. I had a broked bearing stay. Thats a plate behind a flywheel where starter clutch sits on needle bearing . I am replaced it , cleaned and lubed everything in there and its ok now.

                        @nottsbiker damn, I know DHL ship from france and I know their prices are rape but I think I'm going to keep check on those websites when I get on the computer my French is super basic so navigating is difficult 😂 Thanks for the hook-up I'd love a wr200 but they're so hard to come by!!

                            You ever want to go over give me a shout and I'll be up for it.

                            We have a Trafic with pop top tent and a small trailer. In total I could probably manage 6 trail bikes at a push.

                            Ferry has just cost me £650 which includes cabins and dog crates. Cheapest ferry on the same route maybe £500 no frills. Tbh I'd go via the tunnel as is around £200 to cross and return say a week later.

                            You cant beleive how good the roads are here and how quiet they are too - bikers paradise 🙂

                            Bikes like the TDR were made for this type of country.

                              @nottsbiker Done the French tour a few times on big bikes, down south and to Spain, a much more bike aware country, loved it.

                                Spark Plug looks fine mate.

                                I didn't think it was fueling.

                                A plug chop must be done at high RPM WOT and the ignition to be switch off and clutch pulled in then bike pushed home

                                You don't get any sort of idea of how the engine is performing whilst pootling around. However you do see if there are any problems.

                                  @calum isn't it bad for the engine just shutting of at ~12k rpm? Does he get lubrication? Feels so sketchy to me.

                                    Confused about the reed valve. Took it out last time and I don't remember which way to put in. On a manual it says that there is special cutout on the corner but I don't see anything on mine. There is white marking on the top in the center. Is it correct like I am holding in a hand or upside down? The upper gap seems wider than down one.

                                      As far as I remember the two stopper plates should be the same spacing. If they are not then a previous owner might have tried to modify it to open more.

                                      Not sure if the reed valves have a top or bottom to them but if it looks symmetrical then it shouldn't matter which way up it goes.

                                        @calum isn't it bad for the engine just shutting of at ~12k rpm? Does he get lubrication? Feels so sketchy to me.

                                        @irongamer727 Hence why I said clutch pulled in

                                        So it's not shutting the engine off at 12k RPM. You shut the engine off and pull the clutch in so the RPM's go to zero.

                                          Another update with the brand new issue

                                          Cold bike. I couldn't start start it. It didn't accept the throttle. Started with the choke only. When warmed up everything worked fine with the choke off.

                                          Spent about 10 minutes on adjusting the carburetor air screw (to get the highest rev on idle)

                                          Noticed that the bike is heating up a bit to fast. (Heat arrow pointed at 3/4)

                                          Decided to go for a ride

                                          In the beginning accelerated well, after 2-3 minutes started to feel like something is dragging behind.

                                          Engine was running very slowly and it didn't accept the throttle.

                                          I stopped and noticed that in neutral gear is hard to push bike forward of backwards. Looks like the engine is tight?

                                          When it gets colder then gets back to normal.

                                          Any thoughts?

                                          Regards

                                          @tdrnoob Due to not finding the problem I started to check the back wheel. I felt that it it could be something with the brakes/wheel.
                                          And it was the rear master cylinder fitted in wrong position to the frame. It was fitted on the frame and supposed to be behind the frame... That what caused the brakes to drag.
                                          Such a simple thing. And such a noob.
                                          But so glad that I found this issue and is fixed now.
                                          You know that feeling when after long disappointment you feel full wave of happiness.
