Title: Honda SL100/SL125 Engine Swap, Restomod
Post by: cbinvb on Oct 03, 2016, 13:31:13

The SL100/125s are pretty cool imo
330mm shock, 700mm front forks, 16 inch rims
CB160 swingarm to get a little more length over stock

Not crazy about the mags
Found these 3.00x14 spoke rims on aliexpress

I went with 120/80-14s front and rear
The front end is from some pit bike

An ebay'd xr200 motor can drop into this for a 220lb bike; need something capable for stints on the highway

Here it is in the middle of tear down and inspection, for new top end, beefier clutch plates/springs, and modern oil pump
glad I did, because whoever had this motor before me didn't know how to tighten the cam chain so it chewed into the cylinder
and washed the whole thing in metal shavings.
And oil spinners work really well.

since it was originally drum brake, I will sort something for the rear disc conversion

Very cool little project.  My first "bike" was a little 50cc Honda.  My dad still has it out at the farm and my nephews ride it.

I have made a little bit of progress on this build. 

Have all the wheel spacers made and the front and rear brake hangers fabbed as I am going with Brembo 84mm crabs instead of the KTM calipers I originally had.  This means I had to switch out for larger brake rotors becuase the crabs hit the spokes on the wheel with the smaller rotor diameter. 

Time for paint

 Looks good man. I was wondering who did your cylinder head/cylinder work ? I am building an SL175 at the moment and need the head redone and the jugs honed

So there's a little place in North Baltimore that did my work.  https://goo.gl/maps/z9RXWstnaAA2

Otherwise you could call up Powroll and Jerry will let you know what's what. https://goo.gl/maps/UMEyts9cQao

Holy shit, I like this little beast.  Good job so far!

Thanks, its real slow going during the semester but winter break is coming up in Jan so I try to finish it then.

Hey.  Yea, I brought him everything disassembled but with new valves and seals.  I asked him to recut the valves seats and bore the cylinder to match the piston i handed to him.  He gave me everything back assembled and I put the new top-end on at home.

Rad little scoot.

Are you in the B-more area?


Thanks Bud, yes I am.  I go to UMBC

Hey all, here's a little update on the mid size.

Its coming along slowly but most of the worst is done. 

- everything thats getting PC'ed is done
- electrics are all sorted, fingers crossed
- motor is rebuilt, painted, wired
- front end is coming together
- instruments and controls look good

Mostly just need bracket fab, paint tank and finish seat, cables, and tuning.  Not small things, but now that the weather is nicer i can spend more time in the garage

Thanks guys. 

Those forks are marzocchi clones from china, about 27in long with 4-5in of travel.

Starting to get down to the last few bits. 

Tank is painted, I went with red (pics next time)
Seat is nearing completion (anyone know a good upholsterer in the B'more/DC area?)
Rear wheel aligned and spaced and calipered
Wiring in and mostly hooked up

I am 6'1" so here's a few pics for scale

Starting to wrap things up, just a good deal of reassembly and tweaking.

Its really small when you're up close or sitting on it. Yet, feels to be really solid and rigid, not like the shock are oversprung, but that there's no flex in the frame or front end or components.

 Looks like it's going to be a blast to ride. Did you do that seat yourself, it looks great.

It is a really fun ride.  I haven't done a top speed pull yet, but i've had it to 70 and it seemed like there was more left in the bucket. 

I did the pan and foam while GS Upholstery in Millersville, MD did the tuck roll.
