Making good progress Johno.
The rain made it here last night, now I can leave the house and have a crack at my gear box.
This is a little late in the piece given your time constraints, but I'll throw it out there as a discussion point anyway.
Back in the early nineties when I was running around the southern half of Australia chasing speedway meetings, we would run light plastic discs that where used on trotting gigs to cover the wire front wheel of our sidecar.
While I wasn't averse to leaving a few tire marks on a passengers helmet or leathers, unlike some others I draw the line at chopping up appendages.
Question.......... Would those plastic discs cut down on drag it they where fitted to Johno's wire wheels?
Cheers,
Brian
