Chain guard clearance is 'generous'. Which is nice because it is one less thing to chop up.
I remembered your tyre ripping story Lizrdbrth when I was calculating the risk of just a longer chain.
It took me about five seconds to decide to go all the way and stretch the swinging arm.
The new tyre has got a much greater rolling circumference which will effect the gearing, I'll probably take a wild arsed guess and go for 55.
Also it is much heavier which will probably overload the already pitiful rear shock, some thought needed here.
Here's where I am tonight:
I'll weld it up tomorrow.
Bagger, do the police check your tyre approval?
This Carlise states 'not for highway use' which I'll grind off.
On most occasions our police will look at what it does say, not what it doesn't....i.e, if it doesn't
have a DOT mark they don't seem to worry too much (unless you've just run someone over)
