    @oldman yea I think I could switch a new plug in when I fix the bike. Just a bit shitty that the iridium plug stopped working after like one month

    @claws Iridium plugs tend to have a shorter lifespan over regular plugs. Mainly due to the stronger spark they produce. I used Iridium plugs in my DTR and noticed a definite drop in performance after a month's use. As plugs are as cheap_as_chips they are an easy component to replace. 😉

        @claws The iridium plugs are cheaper on ebay, especially if you buy 4 at a time like I do; :winking_face: :grinning_face_with_smiling_eyes: :winking_face:

          I have had the same iridium for years. My starlet has had the same iridium for years too.

            Yes, not normal for any spark plug to be needing replacement within a month. It'd say something about how your engine is running. Too lean or too rich.

              @DTRLuke the stock carburetor was running pretty badly and i couldnt really tune it either since the screws were seized so i switched to a 36mm keihin pwk. it was running pretty good actually until i switched a few things including the fuel tank

                You can buy chinese remade DT carbs, a few people have them on their bikes. A lot probably don't even realise they have a fake carb.

                          @claws The Keihin carb is probably also fake. Most carb's are fake on eBay etc. If you order one directly from Yamaha, then it's most probably OEM, but will be double the price of the fake.

                                          Uhhmm

                                          Inner rotor kits aren't that great for road going machines.

                                          You won't be able to run lights, charge the battery etc.

                                          Great for racing machines. But then you'd want a lighter chassis etc.

                                          Always Originate, Never Pirate!
