    @erion
    More questions! Does your bike rev freely above 7000RPM? Does it have a standard exhaust, or an aftermarket one?…

        @erion it is 1994. My 1999 DT125R french import says exactly that on the v5. But on Yamaha database it says RE. It's not electric start, I believe the E means it's a European model which were different in a few ways.

                @erion don't know much else about this year to be honest only some of the older European ones has a little washer type thing spot welded into the exhaust at the header to close it up and restrict it. Remove the exhaust and you'll see it if it's there.

                    @erion Bro you need to chill 🤣 These bikes are incredibly simple. The fact of the matter to me seems like you are accepting a botched repair rather than taking the time to do things properly.

                    Tapping up the ignition switch, and God knows what other botches you're doing, is going to bite you in the backside big time. If that wire comes loose on a ride out you're going to be stuck in the middle of nowhere with a brick of a bike.

                    Juat relax and take the time to do the job properly and it'll pay dividends later on.

                        Sounds like an ignition problem to, presumably it was working before you messed about with the ignition?

                          @Calum no i installed the ignition yesterday afternoon and took it for a ride it was good but i had the same problem a week ago and i thought it was carb related so i took the carb out and took it for cleaning yesterday i put the carb back in on the morning and i rode it like 2 hours it was just fine but now its doing the same thing it did before a week

                              Still sounds like an ignition issue🤣

                              I had this when I mistakenly bought a cheap chinese "Racing" coil. The bike would ride fine for a while, but then would start misfiring and running awful. Since I did a nut and bolt rebuild on the bike, I didn't think it was the coil since everything was new on it, but as time wore on I decided to revisit the issue. A brand new Genuine coil later and the bike was back to running sweet again.

                              I run a similar "Racing" coil on my RS...need to swap that out at some point.

                              If you're comfortable that the bike is being fueled properly, then I'd be inclined to look at the ignition as you next port of call.

                              Had a similar issue on a 2001 DTR, where it would only start if you kicked it over whilst turning the ignition from "Off" to "On".

                              It was the side stand switch on that particular instance, and it was looped out and this was the only way to get the bike running.

                                  @erion Key? Or ignition barrel.

                                  My bike was stolen in 2010 and I replaced the ignition barrel with a Wemoto one. It's not bad, but it isn't great either. About a year later the whole ignition assembly crumbled in my hand and I've had to hand solder all new cables onto it.

                                          Yeah, that’s a cheap shit ignition barrel and key! It could well be your problem…

                                          Try drawing the carb, just to make sure the bowl is filling with petrol…
                                          Did you put fresh petrol in?…
