Title: Green SL200 Mini
Post by: cbinvb on Oct 03, 2016, 13:31:13
Here's build I've been on little lately between classes so I figured I would start the build thread

Inspiration, a honda Monkey done by G'Craft out of Japan

here's my first documented mini bike build, a 200cc Honda Ape.  the seat height is 29" , 12" rims, 215lbs.

SL100 tank and frame picked up off ebay for $40 shipped and a tank for $60
That's like half the battle

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

I'm not crazy for mags and I think the 16's are still a little too big
Found these 3.00x14 spoke rims on aliexpress

I went with 120/80-14s front and rear.  At this point I really started to like this build and have confidence in its progression.

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.

-1.5" seat over stock

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

The seat pan is ready for upholstery and will go out this week.

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.

- reamed the axle tube to accept a 14mm axle, which is what this cb175 swinger needs to work with my frame
- shocks ordered and tested
- finished the motor and fitting/bracketing
- fitted the exhaust, now feeling out the style of exhaust i wanna go with
- sprocket alignment

Its more work than I expected.

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. 

Left to do is mostly paint now.

 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.

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
