Don't knock what you haven't tried!
In 3000 miles, nothing! It's been brilliant.
Originally part of an outfit which cost me £700 in March 2009. Due to lack of use, I sold the 'car for £350 a couple of months later. The bike itself was £350, which is pretty near the upper limit of what you'll ever pay for a Jawa.
I previously owned an MZ ETZ 250, which only did about 40mpg, worse than my VFR 750! However, I was hooked on the whole simple stroker thing, and ended up with the Jawa, which returns low fifties mpg and though not fast -around 70- is a really satisfying ride due to its pulling power in all gears from 1500 rpm, very comfy with good seat and plenty of arm- and leg-room. My pillions prefer it my VFR 750 with its low rear pegs, and you don't slide forward under braking. Praise indeed.
Let's deal with the alleged weaknesses of the Jawa, the bike the press loved to hate. Premix-so what? Points ign.- have looked at them but no adjustment req'd in 3000 miles. Poor build quality - the bike's 20 yr old and totally reliable. Styling - OK, I let that one go. But it certainly turns heads, when's the last time a silver Ford Focus managed that?
Worst feature: without doubt, the horrid gear change, GRIND with neutral between all the gears (not false neutral, they're meant to be there). Thank God there are only four.
Best feature: Tank detail "TWIN SPORT" - who says that only the Brits have a great sense of irony!
Would you buy another motorcycle from this manufacturer? Yes
