I bought it with these faults:
Indicators didn't flash
Headlamp very dim / diffuse beam
Paintwork scruffy.
After about 800 hard miles it hasn't missed a beat
Sorted the electrics, serviced it and it runs fine.
Does everything you'd expect from a tiddler, and then some, although brakes aren't brilliant and headlamp even less so (6 volt, direct magneto).
I used it for the Welsh National Rally this year, and got the Platinum award, having found 22 checkpoints, all over North Wales, covering 430 miles in 15 hours. Flat-out all the way and never gave any cause for concern. Other competitors were amazed at its performance, as was I!
I had a T80 that I bought in 2001 and used it for just over a year. I replaced it with the Honda C90 that ended up getting stolen. I preferred the T80 for several reasons, these being; better tank range, shaft drive, smooth gear box, cheap parts.
Although the C90 had better torque and 12 volt electrics.
I would still have the T80, but got rid of it because one of gearbox bearings were badly worn, thus needing an engine overhaul which I never had the time to do.
