O&RBike

Number one grandson's fiancé got left we us for the afternoon. She showed great interest in the tractors. She doesn't drive, so some instruction on driving was done.
 

 
Someone else had to get into the act.
 

Not mine...If you live in Chicago area this looks like a pretty good deal.

Thanks guys...
 
I do have a video of my son riding it...we been holding off posting it because we are still trying different sprocket ratios and have a new clutch on order and we think we can get it better than it is.
 
It goes forward when you hit the gas but it's not going to break any land speed records lol. 
    Actually it's pretty much what we had expected...something just under 20 mph, maybe 16 or 17 mph. That's not bad considering most O&R Tom Thumbs only run about 10 mph. Might be able to find another couple mile an hour by tweaking the ratios...but 1HP is still 1HP and there's just so much your going to get out of that engine. It also doesn't help that he's 6'3" and 180 lbs. If you put an 80 lb kid on this thing I think it would easily run 20 mph.   We only had time for one quick test ride and he had to hop a flight back to school. I'll send the bike out to him and he can fool around with it some more in his spare time.    Overall I would call it a success and we had some fun working on it. He's already planning a scratch built bike with more HP for the next project.    I will post an update with the new clutch and sprocket ratios installed.

Thanks guys...

Ready for a test run....
 
   

Break in run....(video)
 

Odds and Ends....
 
Turned a longer solid aluminum seat post for it to gain some leg room ...
 
   
 
Swiped a set of suspension forks off another junk BMX bike:
 

 
We had to press a sleeve in them to fit the vintage aftermarket handlebar stem. Aside from the internal springs, these also have the provision to mount a front caliper type brake. (We had to ditch the original coaster brake with the custom rear hub.)

Getting there....
 
 
   
 

Ready for a test run....
 
   

Started roughing out a chain guard for the pto side:
 
 
 
 
 
 

Down on two wheels ....    
 
Right side spring loaded brake handle serves as throttle:

Thanks.
 
 I think I got a little carried away with the photos and I reached the limit in my album before I could finish the story.  I found out I could increase my limit by becoming a supporting member, so we're back on board and I call it money well spent.

Bent up a fuel tank bracket and plug welded it to the frame behind the seat...  
  Added a strip of self stick foam padding on it :  
  And clamped the tank into place :  

Both halves of the finished mount :
