Stihl 08S mounted on a 1969 Schwinn Stingray

[gee_dubya75]

This is what happens when you store an 08S too close to the same vintage Schwinn Stingray. A buddy and I at work thought it would be a good way to use the saw since the oiler quit working and it's just too heavy of a saw for the amount of power it makes. We still need to fab the exhaust and work on the gearing but the Stihl fired with two pulls of the cord. With the current gearing, at 7000 rpm the wheel speed is 80 mph so we'll probably have to go with a bigger rear sprocket.

I'll post some more pictures and a video of it in action when it's done.

You're missing the Honus Wagner baseball card on the front spokes.

Nice! Can just see someone sitting on it at 80 mph.

80 mph? your post needs a video :hmm3grin2orange:

From a helment cam

80mph was the theoretical wheel speed based on the gearing. 60cc doesn't have enough torque to getting going that fast on it's own. Maybe downhill with some assistance. I'm shooting for around 35mph as the top speed as that gearing should have decent power from a standstill also.

 

[mitch95100]

Im gonna do somethin like that HAHA

 

[sachsmo]

Awesome!

 

[sawfun9]

Now that's the spirit of hot rodding. Way to go man.

 

[TJ-Bill]

That's pretty cool.. How about some pics of how the chain connects!

yeah that exhaust look like it could get alittle hot

 

[gee_dubya75]

Next time I take pictures the gearing should be figured out and it should have some sort of pipe on it. I'll take some pictures that shows how the chain connects and post those too. For the test run there was no 'muffler' at all and the exhaust port was pointed straight up so it was really loud. The straight pipe will snake through the frame and terminate under the seat somewhere.

I'd be cautious not to cut or damage the actual frame. Looks to be in really nice shape and I sold a frame and some junk parts for $50. A complete original can be $200 to $600. I guess some people want what they could not have in their youth...

but it does look like a fun project.

I have spare 056M. With some work???? might make 80 MPH??? That is ca. 95ccs.

I'd put it on old steel Italian racer like a Bianchi, De Rosa, Colnago.......

Whoops, I forgot my Super Corsa Bianchi cost $1700 in 1982........

Better not gut it.


Will look for a Jap Bianchi./knock off.....

I like it!

When my great uncle was at Purdue (I guess it would have been in the 40's), he put an engine (I don't even know what kind, but it was from some kind of yard equiptment... Old Briggs, maybe) over the back wheel, on a small rack he made... Just had an engage/disengage lever, so you got going on the pedals, then engaged the drive... He apparently rode it home (Washington, IN, about 140 miles south) several times, on long weekends... It apparently cruised at 40mph or so... He showed me pictures in an old album, and I believed him when he said that with the motor on top of the rear wheel, that about everybody who he let ride it, crashed it...

These lyrics are causing me to see RandyMac on this thing next to Peter Fonda ....

In my case, it was three Pete Rose rookie cards ... true story. All came in one pack and I HATED the Reds, since I was a Cubs fan!

Nice! Can just see someone sitting on it at 80 mph.

With their lips peeling back from the wind .....

First thing I thought of! Theres a pawn shop owner around here with a real Jones for old Schwinn bikes. He says that between the Stingrays he has and all the extra parts he can probably make 15 complete bikes.


Seeing this thread caused me to have flashbacks to my younger days. If you couldn't afford one of these new, you could get the parts and sorta make one for yourself. A friend of mine and his brother had one such bike. Had a B&S 5HP engine on it and was terribly balanced ..... had NO brakes ..... I went for a ride one time .... was doing great, rolled up their driveway and the throttle stuck! The rolling projectile I had become missed the garage, the swing set and his Mom before careening off into the weeds ... Just damned lucky there were no sizeable trees around there then. :msp_biggrin:

 

[gee_dubya75]

functional but not done

Ok here are some pictures/videos of the bike somewhat complete. We are looking for a set of disc brakes for it and we're going to make it a two speed. With the current gearing the top speed on flat ground is 35 mph (verified today on a test drive using my Delorme PN-60 GPS) which I'm satisfied with but it still lacks low end power so we're going to add a derailleur and put a slightly smaller + slightly larger gear on the rear wheel of the bike. Slightly larger gear will give it more torque and better low end performance and the smaller gear will make it drivable if you have to pedal it any distance + give you a little higher top end if desired.

If I wasn't 220 pounds the current gearing would probably be ok :smile2:
