Front Fork Noise And Unsmooth Movement

[PsychoPigeon]

2 weeks ago I noticed a creaking sound coming from the left fork when I pushed down on it, it's gradually become less noticeable but if you really apply some pressure you can get it to replicate the noise, like an aching metal sound. It also feels like the fork is becoming "stuck" as it returns to its upright position, it isn't a fully smooth movement. The bike has 24k miles on it and is 5 years old and the forks would have never been looked at, but the mechanic's opinion is that there's nothing wrong with them and that the forks usually always do this over time, they're very adamant the forks don't need to be serviced and that I'd just be wasting my money.

Any other opinions on this? I don't want to let the inside of the forks corrode or get damaged, but at the same time I value the mechanic's opinion.

Oil and bushes really, do you know if there’s any oil in them? Wouldn’t trust the right amount to be in there from factory.

I have no idea, I presume there is because they have been smooth up until now. But the mechanic is very certain that they don't need servicing and it's not like they don't have an incentive to do it they could easily charge me an hour for labour. I think I will try and do it myself.

It's a Yamaha YBR.

And yeah the mechanic did say they went out for a test ride and it felt good to them
