    @Calum I was thinking about some honda alluminium ones , they are same price as the dt 200 , might need some custom brackets 🤔

        What do you guys think about quick action throttles? Found it on ebay randomly chasing parts.

            I run a YZ 250 throttle with a billet alloy throttle tube, so much nicer...

            Recomended.

            Keep it real

                @Zrako Ever ridden a crosser?

                Effectively you are only pulling the throttle a quarter turn before full chat.

                So you lose control of the throttle slider, but you are quicker to go Wipe Open Throttle.

                You would probably want spot on jetting, else risk bogging down.

                  @Calum never rided motocross bike ,so with this Im loosing a lot I think , its not really for the cruising and for the traffic as lot of sensitivity will compress in the 1/4 turn ?

                    @Zrako It's not really an issue, but the original throttle is there to ease the power on and make it easier to just poot around with traffic for the novice rider. It wouldn't take long before you forgot how it was originally and got used to the quick throttle.

                        The yz swingarm arrived today . Postman asked me why I am so happy lol.
                        Ehm. The fitment makes me a bit nervous there. Any ideas ?

                          Yz one is not wide enough. Tried this myself 2 weeks ago and gave up on that idea

                              Anything is possible. No it's not a direct fit, but if it were then every joey would have done it.

                              The only reason I didn't do it, was because I spent many many nights lining up my supermoto wheels with my current setup, changing the arm, whilst trivial, would have undone all that work.

                                At first Im spotted the 2 problems I need to deal with : 1st - the linkage fitment is different
                                2nd - the brake bracket .
                                Wondering if the yz bracket will fit my caliper and line up properly with the disc 🤔

                                    To do it properly you are going to need to realign the whole geometry of the bike.

                                    With the new swingarm you are going to need the YZ brake carrier. Which will need modifiying to either accept your brake, or use the YZ brakes.

                                    Either way the swingarm needs altering to fit between the frame and the engine.

                                    This will cause the sprocket to be out of alignment with the rear sprocket, which is going to to cause undue stress to the gearbox bearings. This will need correcting by either shimming or machining.

                                    You are then going to find the front and rear wheels are no longer in line. So this will need altering to ensure that the front and rear wheels are inline, and the front and rear sprockets are inline.

                                    If you don't then you will find the bike will have a tendency to crab or to cause excessive damage to the gearbox.

                                    This is why my front wheel is off centre from the forks. This was done to ensure the front and rear wheels line up perfectly, whilst maintaining the correct geometry for the front and rear sprockets.

                                    I'm all for the swingarm conversion, but it sounds like you haven't thought this through enough?

                                    If you're going to do, do it right. Is all I'm going to say.

                                    It's just a case of measuring once, twice three times to be sure. This is the reason why I didn't use the alloy swingarm, AFTER I had already done all of this measuring.

                                    I should have done it all at one time and saved myself the effort of measuring twice.

                                    If any of that is unclear I am happy to go into more detail.

                                      I'm all for the swingarm conversion, but it sounds like you haven't thought this through enough?

                                      If you're going to do, do it right. Is all I'm going to say.

                                      It's just a case of measuring once, twice three times to be sure. This is the reason why I didn't use the alloy swingarm, AFTER I had already done all of this measuring.

                                      I should have done it all at one time and saved myself the effort of measuring twice.

                                      If any of that is unclear I am happy to go into more detail.

                                      @Calum yeah to be honest Im thought its lot easier than it really is and I havent the yz swingarm in the hand to get the measurements.
                                      Definitely I have only 2 ways of doing this: properly or stock swingarm.

                                        I'm keeping the stock arm and swapping the wheel hubs over just to keep the project going ATM. I did like the idea of the yz wheel adjustment on the rear as it looks smarter than the dt 1
