Do you have the service manual on hand ? - as this will give you the proper factory service schedule, which is obviously a very good starting point to further guide you.
Also i agree with the mention of the disc pads & chain slider for close inspection.
Proberly worth checking the battery terminal connections - clean, tighten & spray with suitable protectant.
Also pull the rubber boot back from the main wire connector at the starter motor. I found that this boot holds water inside, which causes bad corrosion at the metal connector terminal. The water will run straight down the wire & into the rubber boot. I got to mine in time to clean it up, spray it with protector coating etc. I also then siliconed up the water entry point where the wire goes inside the rubber boot. Should be all good now.
So you mention "i've done oil", does this also include the oil filter ?
In reality at that mileage you're properly good to go with what you've already done - so just pump the tyres, "flick a screw driver over the spokes" and ride on mate, lol.
Cheers.
