I just want to know what that valve cover brace thing is.
Probably a good reason for that!
Wow. I'd like to know what the spring clip cotter pin is holding. Just above the lower triple clamp on the left side of the bike I see a spring clip (cotter pin) holding what appears to be a small box? Could it be a transponder for racing? Or? Never seen something like that.
The other weird item is that strut brace out to the left head. What does that do?
I would totally take it for a spin.
Those Wasps are cool! But Ill trump you for crazy...
They were actually the most competitive racing sidecars worldwide.
Ah, that is elegant. And the layshaft is concentric with the swingarm "shaft". Neat.
It obviously just needs a new battery. It's always the battery.
Im basing that of course on nothing than a vague idea of how I'd start thinking about it.
Probably runs better than mine, right now
AND if anything near a stock clutch will work in that than obviously I could run about in third gear all day long, no problems
my guess, since it's a race hack, the brace from the frame to valve cover is to keep the riders leg from knocking off the carb as he climbs all over the thing, hey, it's just a guess!
wonder if the sidecar wheel is powered. that might explain the chain drive in the first place.
My thought exactly.
Douglas made horizontally opposed twin bikes with chain drive. (england-kev features some in his 2012 picture thread)
Nothing weird about it really. The drive has to make a 90 degree turn somewhere, be it at the end of a driveshaft at the wheel, or at the beginning of a chain at the transmission.
Given the reputation of those paralever rear ends as a "maintenance" replacement item, there's something to be said for a chain drive.
Makes perfect sense to me-- you'll need to design or adapt a right-angle drive and it'd be easier to adapt. Use a splined wheel cup on the layshaft to mate with the output splines on the FD.
Hmmm. I'm inspired. Wonder if there are any plans/drawings on the 'Net? Seriously.
EDIT: Googling "Wasp racing hack" fizzled-- more hits on a vid game. Alternate search names?
"Wasp bmw sidecar" dribbles in a lot of minor hits, but thus is progress.
"Wasp bmw sidecar" with Google Images looks fruitful.
years ago at Carnigie park in Calif. I saw several teams from europe totally destroy the US hack riders. The Wasp hacks were jumping 4-5 times further than the US riders. One Wasp had a 750 Honda 4 in it, the other had a Norton twin. they were taking the jumps like the solo riders were. I was amazed at thier speed.
Bill, there are some Wasp photos in the hack section. ya may find something there. JB
I think it's awesome
A while ago I was asking about fitting a chain drive to a airhead. I was guided to an image of a race/track bike. The gearing was easy to change on the sprockets, dunno about braking thru the chain tho,
I'd love to take it for a blast
