mexicanyella said:I have a CT70 carb and intake. I am not 100% positive it's a CT intake--there's a chance it's off a SL--but the carb is CT. I got both as part of a parts trade and don't know a lot of CT/SL i.d. info. Neither will work well for my project, but the carb's got the petcock on the bowl and the two brass fuel barbs, and looks to be in the 15-16mm range as a guess. I'll take a photo and post it later today and you can see if it's what you're looking for.
I apologize for taking so long; I tried to take photos of the thing and the memory card in my camera crapped out. I'll try to get on that today when I'm out and about.
I'm pretty sure the intake I have is not a CT70 intake, because it looks like the ends of the two fuel inlet barbs are pretty close to the head-to-manifold gasket surface. I think a CT intake must have more rise to it.
The carb I have is so clean it appears to never have been used, but I don't know if it's early or late model as my CT knowledge is spotty. It's got a metal choke lever and the choke closes on a pivot rather than sliding down like a guillotine blade, which I think might mean later model, but....?
If you're still looking by the time I get my camera sorted out, there will be pictures, and I'll try to make that happen sooner than later...
The intake I have definitely does not work on a hardtail Z50. It's pretty well aligned with the bike centerline, which means interference between carb cap and frame spine. I don't yet own a complete softtail Z50, so I can't say for sure on one of those, but I'd guess the same problem would arise.
So I found this guy in Arizona with a bunch of ATC parts. I bought an ATC125M intake from him a few weeks ago, which is the same general port size and flange layout as the 70 heads, but quite a bit longer. And like the ATC70 intake, it's offset to the left, allowing it to clear the low ATC frame spine. Now that I have it I realize I may need to get creative with the air filter to fit it in there, but if I end up doing my own Heinz 57 mellow big-bore stroker farm motor idea, using a 69mm tall cylinder, it might create just enough extra room to avoid unsightly elbows or something to get a filter in.
Anyway, I will continue to try getting you photos of the carb, but realistically it may be a couple days before getting the memory card, getting somewhere I can upload photos (wife's outta town with our photo computer) and whatnot. If you don't want to wait for me I understand. But I definitely don't have a bike that this carb will work on, so it's not going anywhere anytime soon unless you or someone else buys it, and you've got first dibs at this time. I'd love for it to find a loving home, especially in exchange for Mexicanyella bike funds or spare parts.
I'd also be happy to refer you to the Arizona guy, or send him an e-mail asking about it myself, if you like. He may have an entire ATC70 intake and carb, as far as that goes. But obviously the morally correct, conscientous, all-around decent thing to do would be to buy my carb...or trade me some other parts for it. Hey, but no guilt trip or anything.
What year Z are you basing the Heinz on? Is some or all of it in the "Let's see everyone's Z" thread? I'm interested; I like the mix and match approach, especially if the outcome is a good-runnin rat.
Edit: this is an assumption, and you know what they say about when you assume...but if an ATC70 intake bolts to an ATC70 head, and an ATC125M intake bolts to a 70 head, wouldn't it seem logical that an ATC90 or 110 intake would also bolt to a 70 head? I'm guessing the 90 and 110 ones are longer than the 70 ones, maybe shorter than the 125M one. But my point is you may not have to limit yourself to the 70 piece.
mexicanyella said:What's the story behind the diamond-plate upper motor mount?
The elbow fitting in place of the petcock/use the carb-mounted petcock seems like it would work okay if you capped either the reserve inlet or main inlet. You'd only have on/off, but as far as I've seen that's all a Z has anyway.
Photos coming soon, really.
