Timing scatter is clearly visible with a strobe on the fan pulley. A mark such as Dave suggests makes it easier too. No need to access the flywheel. Care is needed as the fan may well appear stationary.
I have a 3 speed box with the flywheel lightened as far as possible on the rim. This combined with the Andes 2nd gear makes hill climbing at 30-40 mph very easy, especially here in the Scottish Borders. The lightened flywheel also helps with quicker gear changes into top on hills.
However, having experienced Malcolm's Yorkshire hills, this set up doesn't work so well there. I am often reduced to 1st gear where the standard 2nd would still work. End up screaming up in 1st and struggling to overtake bicycles! On one occasion the combination of gravity feed and incline caused us to run out of petrol alongside a bicycle. Very embarrassing!
