    Slightly of topic but the same part of the engine, is the gasket on the inlet a rubber one? There’s a rubber one on mine and it has an air leak, I remember on my other engine it was the cereal box type

    @ricky0115 It should be a paper type, quite common for these to let air in here when botched.

        @ricky0115 Use Athena, or OEM gaskets only.

        You can get some paper gasket adhesive to just ensure it's properly sealed. It's what I've used on my engines.

          @calum where’s the best place to get Athena gaskets? I remember pricing up OEM on Fowler’s for the top end was like £40 for 2 gaskets

                @ricky0115 For gaskets and obtaining authentic genuine athena gaskets. Choose none other than PJME.

                But personal preference. I use eBay for almost everything else.

                    @ricky0115 https://www.pjme.co.uk/acatalog/Yamaha_DT125R_Tools___Workshop_Equipment_.html

                    Loctite Adhesive Spray.

                    Bought that like 5 years ago and still use it today.

                    People will no doubt say it's unnecessary. All I can say is I've only built engines with it and never had any problems. But I'll admit it's potentially over cautious.

                      @calum it was made for a reason why not use it! Especially on that annoying gasket on top of the carb
