        If it's stuck in the engine have you tried loosening off the other engine mounts? Might give everything a little bit of wiggle room

          Soaking it in penetration fluid, turning the bolt whilst hammering it out and applying heat to the rear of the cases. I've had this before and it's been a nightmare, but persistence is key.

                Maybe you should get a hydraulic press and press it out.

                    Try a thin cutting disc on an angle grinder and carefully cut either side of the engine, I have done it a couple of times, it's quick and easy

                        @dtrdaz03 Yeah standard DTR to be fair. When they've spent their entire life being owned by younguns that is. Luckily my DT came apart nicely, but quite a few members have had issues. I remember old time member NEV used to soak these sorts of components in Coke Cola for a few days.

                          Happened to me , not a nice experience. My bearings was rotten , seized and I've had to drill, mill and chisel it horribly , then remove the engine with swingarm out of the frame (together) then after long fight I cut it with angle grinder . All that after week of beating with sledge hammer , soaking in hot and cold oils , torch etc etc . Hopefully never again 😆

                            On my first DT after several days of trying to remove the bolt, I eventually got it to budge by doing a continuous heat cycle on it, and going at it with a club hammer and drift. When you thinks it got to be hot enough by now...give it another couple of minutes with the blow torch.
