This is the thread that I have been looking for...phew!!!

: I need some help please with a ride a buddy and I are planning to do from the 27th - 30th of August.
First of all, I am an American living in the UK; known by some as the "Yank on a Triumph." I live in Mildenhall and here is our proposed route:
Day 1:
Immediately after work we are rolling (4:00 p.m.) and plan on heading up to the outskirts of Glasgow which is showing about a 4-5 hour ride then stay the night.
Day 2:
Travel up the Loch ness Clansman Hotel where we stay the night so we can go look for Nessie. This is showing about a 5 hour ride.
Day 3:
Travel across the Highlands to a little south of Aberdeen and hangout for a little bit which is showing a 3 hour ride. Then push off down the coast and make it to Newcastle that is showing a 4-5 hour ride. Stay the night at Newcastle.
Day 4:
Push home that is showing to be a 4 - 5 hour ride.
My first question:
Is this a reasonable route mapped out as far as being realistic to accomplish?
I have been researching a lot of conflicting information about the weather in Scotland. Some sites are saying that August is beautiful and the best month to travel to Scotland and some say that August is the worse month. I have even come across a joke that says you get all four seasons in each day for the month of August.
Soooooo...before I do this journey to a place I have never been to before; could someone help me out and share with me your thoughts/insights/opinions? Thank you in advance and I hope it is a case that I am being too picky trying to square everything away. I just don't want to be stuck in hard thunderstorm showers everyday of this trip and would like to know if that is the likelihood for the month of August.
