I READ THE GOOD BOOK (SILVERS) AND SAW WHERE IT SAID THAT IF YOU COULD START YOU CL77 WITHOUT CHOKING THE SHIT OUT OF IT, IT WAS JETTED TO RICH. I FOUND A COUPLE OF SETS OF NEW NEEDLE JETS AND PRESSED TWO OF THEM INTO MY KEYSTER EQUIPED CARBS AND "WA-LA". NOW WHEN I START MY BIKE I NEED FULL CHOKE FOR A COUPLE OF MINUTES AND THEN A COUPLE OF MORE MINUTES OF 1/2 CHOKE. WHAT A DIFFERENCE, THE NEEDLE JETS ARE SURLY ONE OF THE BIG PROBLEMS WITH THESE CARBS. TOO BAD THEY ARE SO HARD TO FIND.

I tend to agree with Fast Fred with worn needle jets being the problem with running rich in allot of these models. It seems to be more prevalent in the CL77's. According to a very knowledgeable source on this site this may be due to the up sweep exhaust, but who knows. On my current project I am dropping the mains to 125's on a set of carbs I am rebuilding. Like Fred says, you cannot find needle jets anywhere, so I am hoping for the best. I have noticed that Bill Silver mentions running a hotter D6HA plug for city driving. Has anybody tried this to see if it helps. I am ordering a couple and will try experimenting (very carefully) along this avenue when I get her up and running.

Seems that I've seen a 22mm carb body in my "stash" that looks to be pretty nice looking. Make a reasonable offer and a few $$ for shipping and it will be yours. Just swap out your parts is all. Thanks.

Fred and CBX I have sent you both a PM. It still amazes me the amount of help offered and the vast info that can be obtained from this site. I would still like to hear from anyone who has tried running a hotter plug and the results they obtained. I had great results going up a grade while trying to dial in one of my old Triumphs, unfortunately it is going to be a while longer before I am ready to attempt to kick the CL to life.

D8HAs are too cold for some climates and/or setups. 6s worked here; follow the entire thread:
