Thanks matey.
I found the cable sleeving a tad long and it rubbed against the chain, so I used a cable tie to gently hold it closer to the chassis.
I'll attempt the mirrors as soon as I can.
I noticed today from testing the C5 that it works perfectly now I have adjusted the 'fence'!
Braking worked too, although I had to squeeze it tight to get any response. I'll do as you suggested, and run a few trials to see which works best. It's managing to get a good responsive brake, yet still being able to apply it far enough to activate the parking brake.
It was good to ride it agian though today.
Thanks for your continued support.
