1. Adjustable guide bar oil pump (replaced original non-adjustable),
2. Ring gear drum (replaced original cross gear drum)
3. Sprocket, 325" 8 teeth

I cut hornbeam wood 20~35cm thick, logs into metric and branches, I also removed the anti-spark mesh, the chainsaw with the above modifications works like a Husqvarna 560 XP, I worked in parallel with a friend who is professionally engaged in demolition and selling wood and he tried my saw HQ 450ll/2025. to compare it with his HQ 560 AutoTune X-TORQ, his is better for demolition and cannot be compared in that work with mine, mine is better for cutting and cleaning because it is lighter and strong enough, I recommend to anyone who buys a new HQ450ll/2025. to make the modifications that I made, the chainsaw will then be flawless for its power and money packed in a plastic casing like a home/semi-professional chainsaw
