I take it you are not from the Halifax in Yorkshire!
This site has cracking recommendations that cover all over Scotland.
As for hints
- be prepared for 3 seasons in one day. The weather is unpredictable and changeable. A decent waterproof jacket and trousers with lots of vents means you can switch easily and quickly. A helmet with a built in sun visor is best due to the sun and clouds.
- August is a bad month for the voracious midge, a biting insect that can make life miserable. There are numerous repellents, but I found that a head net is the only real way of stopping the little buggers.
- make sure you have visor cleaner with you due to the weather and midges.
- have a read of the UK Highway Code https://www.gov.uk/browse/driving/highway-code
in particular the general rules and rules for drivers and motorcyclists. Check out the rules of traffic lights and round-a-bouts.
- try the whisky and other traditional food and drinks such as haggis, irn bru, porridge, lager, salmon, venison, Baxter's soup, Arbroath smokies, Dundee Cake, Tunnock's Caramel Wafers, Forfar bridies, scotch pie, the many local cheeses and go for an Indian curry. Scotland is famous for its curry restaurants.
- driving standards are good. The road conditions are variable with some local councils better than others at maintaining the roads. You do not legally have to carry insurance documents or your drivers licence with you, but it will save you a lot of possible hassle if you do.
- it does not matter what part of Scotland you go for, there are great roads all over the place. It is feasible to ride the entire length of Scotland, Gretna Green to John O' Groats in one long day.
