Awesome job so far. Do you use paint or powder for the frame? Interesting to see that the frame has a cross bar that uses the bolts that normally bolt the pegs to the engine of Z's and CT's. Have to be honest that back in the day SL 70's were not even on the radar don't even remember them on the show room floor. By this time I was into 125's and a couple of years after that the 250's. Would not mind one now though.....

I used automotive (single stage) grade paint on the frame ( not rattle can) ...I’ve had frames done in powder but not a huge fan due to most of the time the rust pits show if any and the vin#’s get molded over where you can’t read...with paint I can fill rust pits before paint.. the sl70’s were much more rare than the CT’s but back in the day anyone I knew would trade there ct70 for an sl70 without even thinking about it...not so much anymore? I think the sl’s were about $100 more and that was big $$ back in those days...here are pics of a October 1971 popular mechanics magazine on mimicycles. Note the hp rating for the ct and sl 70’s ..I guess they got the extra hp from the bigger carb and better pipe? The head is a little different on the sl’s also..but I question it because they say xr75’s are 5 hp and I know for a fact that an xr75 with spank and sl70 in bottom and top end speed?

Thought I would post this for people who might want to know more about the sl70. Of course they show it in the two colors other than the blue I’ll be painting mine in...lol. Also I think this is a very early sales sheet because the pin stripe on the top of the gas tank on the summer yellow bike is much skinner than all the summer yellow tanks I’ve ever seen and the colors they listed as solid red, solid blue and solid yellow are actually called summer yellow, Aquarius blue an light ruby red...( fun fact) this is for the k-0 models only. 1st year.

Worked on the front and rear rims this past week...still need to true them up before I install new tires but at least there back in one piece..I decided to clean and repack my original Honda wheel bearings with high grade grease rather then pay 40$ an buy new cheap Chinese replacements..the stock bearings were real clean and in perfect condition..I use bread loaf ties to hold all the new Honda
spokes in position before installing the rim..should have a roller by next weekend..last pic has bearings,spacers an seals installed..

Got motor built ..bored 3rd over with new art piston, new valves with seats cut and new guides, if you notice the sl and cl 70’s heads have an extra cooling fin on the top of the head over the cam gear cover,,,the head needed a lot of work but it was the last one I had hanging around loose so I figured I would put it to use…also new cam chain an cam gear an guides, cam cover, valve adjuster caps,, shift forks and pins, seal, clutch plates, etc….also the cylinders on SL an Cl 70’s come with silver cylinders not black like CT’s. To me black looks better…[the motors been ready for awhile so I have more pics of motor in frame coming…ATTACH=full]71487[/ATTACH]
