BSA Air 3: Frankenair
At last I see some real progress in the development of Frankenair, I know it’s been hanging around for a while, but I for one would rather see it right than rushed, so its great to see yet more progress and good ideas coming together. In the last two weeks this bike has leapt forward in terms of build and isn’t far off a dry build finish.
Here is a video of the bike just after the engine had been put back together (read below).
Frankenair is a BSA Ariel 3 trike, thats being converted to 49cc four stroke using a Honda C50 LAC engine.
Having a few of these trikes and ridden them in anger, I know the limitations of the bikes mean 10 – 15 miles is about all mine can manage before it starts to grumble and moan at me. Even though its great fun, the one thing that annoys me more than anything is the inability to just jump on it and ride out, one has to plan everything, the tools, mix the fuel, prat about trying to start it and end up with 10mph on a hill (or less) its sort of numbs the fun a bit.
My good friend Nick had the idea a couple of years back to convert one of his bikes to the same LAC Honda power (being as he is from a Monkey bike background), and it seems to of ticked lots of the boxes I want. E.G. easier starting, more reliability, faster (cruse at 30 sprint to 40+) no mixing fuels and just as much fun as a stock bike. So a plan was hatched and its nearing its final stages all thanks to Nicks hard work and my titing about trying to assist.
Over the last week Nick has been working harder than ever down the workshop, several jobs still need to started; but most of the big ones are near completion, so the bike is on the home straight.
To start with the engine rebuild images are shown. It was a runner but it had low compression, a strip de-coke and rebuild later and its a nice strong as an Ox engine.
Once reassembled it was run up by Nick who shot a couple of videos:
The first shows it charging.
The second video show the kill switch via a brake switch that will be connected to the throttle (yes its complex till you see it)
