        Hello there!

        Welcome to the forum.

        That's certainly a long time ago? What DT did you have back then? An mx?

                @kevb1967 not enough power to pull the gear. Probably need a smaller front sprocket

                    @kevb1967 welcome, very nice looking DT you have. My French import has the 3rm-30 CDI and I understand that they're one of the best.

                        @kevb1967 mine has no clocks and it has the 170 kit but it does have very good top end and revs freely. Also the powervalve is pinned open so after about 6k it sort of comes alive. Is your powervalve working ok?

                          Unfortunately, the 2002 models were heavily restricted. Even with the derestrictions you can still expect problems.

                          Get yourself an aftermarket CDI and all those problems will go away and it'll fly through the gears.

                          Looks tidy though!

                                  @kevb1967 no it's not restricted but if you have the 3rm-30 that is the best one, only available on the French models from 1999-2002 and apparently quite special and rare. Here's a link to a German website which explains the different CDI's. http://dtpedia.de/mediawiki/index.php/CDI_Steuerteile
                                  I don't think your problem is a restriction problem, only starting on full throttle from hot? Maybe fuelling or maybe compression? Sounds like your bike is a full power unrestricted french import.

                                      @kevb1967 I mean, it's a 125.doing 70 like that. Could just be gearing.

                                          The 2000-2004 era were notoriously restricted.

                                          Also appreciate that a lot of these bikes were ridden by youngsters weighing 60-70kgs.
