I believe on a 175 twin that's the stock location for the plastic spacer, at least thats where it was stuck on when the engine showed up. At first I tried to modiify the stock intakes but the alum. or whatever their made of doesn't weld very well. So I turned up two tubes of 6061 and 4 flanges of the same, sawed them where I had too, and Tig welded them together. I still have to use a caribide on the inside to clean them out, and clean up the out side too. But short of making two pattern's and casting them, it was the only way.

I'm not sure it really matters which side since it's just to break up the heat,i think the z50's also have it at this end.Will have to double check.
3-series stainless tubing & plate can be used to good effect for custom intakes. However, your aluminum intakes are an impressive display of welding talent and very much in keeping with the rest of the hardcore metal fab on this bike. Anyone with a basic understanding of working with aluminum will be suitably wowed, maybe even more than with polished stainless versions.
The location of the phenolic plastic heat insulators varies by bike. CT70 K0/K1 models had them between the carb & intake tube. That keeps the carburetor cool, while also preventing over-cooling of the intake; in cooler ambient air temps, the intake can become cold enough to precipitate gasoline out of suspension, seriously degrading air/fuel mixture while riding. IMO, that's a non-issue with the 175 twin; the intake is a lot shorter, shielded from airflow while riding and, this is a completely different motor, with different heat distribution. Have to think that Honda engineers knew what they were doing.

Well, we now have footpegs, and a kick stand. widened a old KO foot peg just under 2 in. and cut off the old stock engine mounts. attached the pegs to some new plates to bolt to the eng plates.

Thanks for the kudos Bill, The shifter will work, but might shorten it an inch though. to fit your foot better. The kick stand is on now, This weekend I need to stick the front end back on to see about the kickstand and some other things. I might have to lenghten it though, this bikes sits about an Inch or so higher. also have the gas tank notched now and welded back together. Next is Exhaust.....OH Noooooooo ha ha

I like the attention to detail on the gussets. Looks factory.
As for the kick stand I’ve noticed the stock setup is susceptible to bending at the point of weld were the rod is welded to the clevis. May be something to consider with the heavier bike.
Did you machine that swing arm pivot bolt from scratch? Looks like lathe tool lines on the hex head.

Dupa, I Like your new Avatar! Hadn't thought about the kickstand bending when I know how long it should be a guesset there would be a good Idea. Yea, I machine'ed up the swingarm bolt, had trouble finding a good 1/2" bolt long enough and with short threads on the end. also its stainless.
Your footrest assembly really does have the OEM look in spades, more CB750 than CT70. Not only that, but you've taken a normally ignored component and turned it into something that adds a finishing detail.:41:
On the kickstand issue, I wouldn't be overly concerned about bending from the added weight of the engine. True enough, most originals are bent. But it's from abuse, not the weight of the bike. Not sure how much force is required to bend one at room temperature. I tried straightening a couple of them years ago by clamping the clevis end in a vise and ended-up dead-lifting the end of a 600lb work bench. I feel reasonably sure that there's slightly less torque applied by a parked bike, even one with a 175 twin in the engine mounts:21: Maybe make a mental note so that you know, early on, if it's bending. Easy enough to modify, repair, or fab a kickstand even with a finished bike, if need be. It probably won't.

Got the CL pipes on Tue, What a suprise! They bolt on! Still have to shorten them some. Think I'm going to use the CL muffler too. was going to run two pipes like a early 305 But have talked it over and it needs to look more like a Early CT.

Dude, that thing is so awesome. Next time I'm in Cali (which happens fairly often), could I drop in and see it?
Couldn't agree more with the choice of exhaust, it ties everything together and comes amazingly close to replicating the basic line of a stock K0 muffler. The slotted heat shielding will be icing on the cake. My question regarding the engine guard tubing diameter has also been answered, there's no room for anything larger. And, with the headpipes in place, the assembly takes on a very different appearance - less engine guard, more structural brace. With a different visual point of reference, the visual scale is different and it doesn't appear spindly at all.
From the engine up, the dimensions of this bike aren't as different from a CL175 as most probably thought. Looks like leg clearance won't be an issue. About the only obvious difference is the slightly rearward location of the muffler outlet and it's so close that cutting & sectioning the headpipes to move the muffler forward probably isn't worthwhile.
Can't wait to see your ST/CL175 (SC/TL175?) fully assembled at this point.:16:
