Throttle Removal

[jplato13]

Hello,

To start i have inherited a 1966 ca77 dream from my grandfather that appears to be atleast 99% original. However it did sit for over 30 years before i received it. After trolling this sight for almost 2 years i have found most of the answers that i needed to tell if this is about ready to try to refire. At this point it appears to be, there appears to be compression in the pistons, the points and the spark plugs both look great. The carb however showed the effect of sitting with gas in it for over 30 years, so i bought a replacement for it. To get my old carb off i had to cut the throttle cable as the slide was (and still is) stuck.

Now to my question, i searched for how to remove the throttle and the only thread i found said to remove the calmshell. After looking at my bike for a few moments (its stored elsewhere) i believe i know where this is, but was hopping to get some conformation. When you remove this "clamshell" does that allow the throttle to slide off?

Any help would be greatly appreciated.

Thanks

I believe "the clamshell" is the silver half moon covers that sit in front of the carb and hide the airbox. I may be wrong.

If the carb is already off the bike, the only thing left to remove is the ring that screws on the top of the carb. I would spray it good with penetrant and let it sit a while before trying.
Never heard the term "clamshell"

John, I am assuming you are talking about removing the throttle from the handle bar? If so the "clam shell" is the aluminum casting holding the throttle on. Two phillips screws and it should slide right off..................D

I've heard the carb covers referred to as 'clamshells' before; maybe on eBay- can't remember where. I'd bet that's what the author meant.
I didn't have them when I got my bike and I really wanted them; they add something to the lines of the bike that I really like. Now that I have them I understand why they're so often missing- you can't even open the carb bowl with them in place!
