      @Calum yeah everything is connected and buttoned up it was doing this before I rebuilt it so it's not something I've caused pv works great so I got no idea you don't notice it when riding unless your practicing wheelies

            @declan Oh yeah that sounds like it's running lean.

            You could just try a lower needle setting on the carb. See if that cleans it up slightly.

                @Calum just dropped the needle the hesitation is still there but I've noticed when hot if I switch on the choke the bike does it didn't previously do this is this normal?

                  Once the bike is warm the choke should kill it

                    @finnerz89 thanks bud, @Calum do you think the hesitation could be my header leak? And is it normal to have smoke coming from the powervalve mechanism

                      Smoke shouldn't be coming from the Powervalve area.

                      You need to sort these little niggles out in order for us to really identify the problem.

                      It may be a combination of a lot of things that are causing these issues.

                      Sort the powervalve out and we can move on from there.

                        @Calum understood I'll see what I can do I think I need a new expansion chamber the current one doesn't fit must be from the dtx or something

                          @Calum right so the right side is not leaking but the left is as the video shows mixture too rich?

                              @declan Not really. Two strokes are not made anymore for this reason, they're oily.

                              To me it looks like the oring needs replacing.

                              The exhaust should be dripping from the expansion chamber usually.

                              I'm sure someone will disagree, but when it comes to oil, I'd rather run a little more than a little less.

                              That post the other day may interest you as it is possible that the little bush can wear out causing excessive play in the powevalve housing.

                              It could be this as well.

                                @Calum the left side don't smoke much I thought the right side was smoking badly but that was because of my header leak that was causing me to think this, when I got the head back from the shop it was the first time I had ever seen a powervalve never mind install one so it's possible that I incorrectly installed something on the left side as I used no images or instructions when doing so

                                  Can't really go wrong mate. Two halves only go in one way. Then a bush with an oring and the pulley and end caps.

                                  Use AJ Sutton exploding diagrams if you need reference.

                                  To be honest, the DTR DTRE engines are pretty much the same so fitment of exhaust pipes will be fine.

                                  It's just the frame mountings are different.

                                      @declan I don't have one handy. It's all in my project thread.

                                      Uhmm a hammer isn't going to fix the issue bud.

                                      It's ally so it's not going to like hammer hitting to it.

                                      It's probably just the O-ring needs renewing bud.

                                          @declan Oh I thought you meant you were going to hit hte powervalve lol.

                                          Hitting it with a hammer probably won't do it much good.

                                          You need to heat it up and bend it. oxy acetylene will get it hot enough to bend itback

                                          Always Originate, Never Pirate!
