1971 Honda SL90K K1 #02

SL90K-250012

Completed 3/23/2013

This is the 2nd Japanese Domestic SL90K that I've restored.  Apparently there was a cc limit for certain ages in Japan and they made a 90cc version of the U.S. spec SL100.  This bike is not to be confused with the U.S. SL90 made in 1969 that was the first to be introduced Honda Motosport lineup as they are completely different bikes.  The SL90K's had a center stand, turn signals, white reflective stripe on the front fender, upswept exhaust to make room for the rear buddy pegs and a seat that resembled the SL100 K0, but with a buddy strap.  As you can see, this model has differences from the SL90K K0 model in that this one has a black frame, crossbar handlebars and the addition of a tachometer along with the speedometer.  You will also notice that all the decals are in Japanese writing throughout the bike and the reflective stripe and triangle on the fenders. 

Here is a shot of the reflective stripe on the front fender.

6V 1-wire turnsignals.

Upswept muffler to clear the buddy pegs on the rear swingarm.

Unique badges that I had made.

Buddy strap on the seat for 2-up riding.

License bracket is a two piece unit that differs from the U.S. version due to the size of the license plates.  The rear taillight lens is unique in that it has the yellow reflectors on the side.

Unique LH switch for the SL models which includes the turnsignal control.

Speedometer is incremented in kilometers.

Check out the low original miles on this one.  When I got it the piston was frozen in the bore but it showed no wear whatsoever making the low number believable.

That says "Helmet Holder" in Japanese.

Reflective triangle on the rear fender

Also differing from the U.S. model is the inclusion of a center stand along with the side stand.

Battery drain routing information decal.

And here is the tire information decal, also in Japanese characters.

Assembly in process 01/06/2013 - 02/17/2013 - 03/03/2013 I've had to replace many a part on this bike due to a rusty starting point, but everything is coming together.  Used my last NOS set of front forks and last set of NOS rear shocks.  Coming together and just lack a few details.

I'm looking forward to starting....and finishing this project.  This will be my 2nd Japanese Domestic SL90K.  Apparently there was a cc limit for certain ages in Japan and they made a 90cc version of the U.S. spec SL100.  This bike is not to be confused with the U.S. SL90 made in 1969 that was the first to be introduced Honda Motosport lineup.  Completely different bikes.  The SL90K's had a centerstand, turnsignals, white reflective stripe on the front fender, upswept exhaust to make room for the rear buddy pegs and a seat that resembled the SL100 K0, but with a buddy strap.  As you can see, this model has differences from the SL90K K0 model in that this one has a black frame, crossbar handlebars and the addition of a tachomter along with the speedometer.  You will also notice that all the decals are in Japanese writing throughout the bike. 

This is how I found the bike with the various parts pretty rusty and it will take a lot of new parts to bring this one back to live.  Just like my first JD SL90K1, this one shows very little usage on the speedometer.   Shows only 66 Kilometers, but parts of the bike sure don't represent that low number......however, look at the tires appear to be original.  On the first bike that I did, it appeared to have a reflective tape stripe on the leading edge of the fender.  On this one, it appears to have been painted on.  I have the painted kit all ready to go for this one and just need time to get it disassembled and start the process.
