I've discovered that the common trend is to make these bikes more long legged by increasing the gearbox sprocket diameter. My slightly tuned, 4 speed 350, on standard 16/38 gearing, annoyed me on long hills because of the large gap between 3rd and top. Third was too short, 4th too tall. I decided to optimise the bike for unmade roads (I often use it to explore byways and unclassified roads) and fitted a larger rear sprocket (46 teeth). Although it reduced the top speed, it transformed the mid range of the bike and the bike pulled far better up those long hills, without me having to constantly change gear. Unfortunately a 350 doesn't quite have the grunt of a 500.
I'm now looking forward to trying out the 5 speed box I've fitted; I've retained its standard 18 tooth sprocket. The overall gearing of the bike will now be somewhere between the two previous setups. The two advantages I see with the 5 speed box are more evenly spaced ratios and 1st gear is lower. Hopefully this will be the best overall compromise for me.

Built like a gun... could go BANG!
