How can I add a little resistance to the enricher cable on my C.V. carb. It is from a 90's fatboy but now resides on my 85 flht. I used the stock cable and made a keyhole bracket that mounts to the bracket that the horn hangs on.. Looks factory. It has always pulled itself in after running 10 minutes or so and I kind of liked it that way.
I can be forgetfull.. Now that it is getting to freezing up this way though it will not stay all the way out without holding it.. Is there a simple solution to tighten it up. It feels like your pulling against a spring when it is all the way out.. I really don't want to tear the carb apart.. I am thinking about maching a two peice lock collar that I can wrap around the outer cable and cinch down a little.. Just figured I would ask first.
Thanks.

The knurled nut is the friction adjustment and there's a metal nut that clamps the cable to the bracket on the backside. I've seen a lot of cracked cable housings, (in the threads), because it was overtightened or just cracked due to age, vibration, etc. If the housing is cracked or split, the friction cannot be adjusted and the knob will not stay out on it's own. A new cable costs about $15 at the stealership.

Thanks, all.. I thought the knurled peice behind the knob was just part of the housing, this one has a plastic nut on the backside of the bracket. Everything I have read before swapping over to this carb said to very careful about overtightening the nut and to also be careful with the plastic fittig where the fuel line goes.. I will pull the cable out of the bracket and take a good look at it..
I have three different service manuals and many articles from American Iron on the C.V. carb and not one mentioned this..

So my XL sporty choke cable has started slipping too. The crappy plastic knurled knob was tightened too tight or the threads were cross threaded. Buying a direct replacement sounds like a waste of time/money for the same crappy plastic threads.

What do you think about this universal Mikuni cable with metal threads and nuts. Has anyone custom fit this cable to a CV carb? Looks like the same end.

The enrichener is meant to be used when you start the bike and it works much better than using the throttle. You don't need to let the bike idle for long before you start riding- no more than a minute or so. It will not foul the plugs unless you leave it on for many miles. When I couldn't tighten mine any more I used one of those little spring loaded clips clamped behind the knob to hold it out til I got it replaced. Think I got that idea from this forum.

Yea, Ive always used the enricher too, adjusting it throughout the ride. But I ride year round and at night working graveyard. It gets and stays pretty cold here at night. During the winter, I only can slide my enricher in halfway or itll die. If Im going hiway speeds in winter, the cold air keeps the motor too cold to fully warm up I guess.

I cut a chunk of vacuum hose to fill the space, then slit it down the side so I could snap it over the enricher shaft. That way I dont have to look when riding, and I can close the enricher to the half way point and it bottoms out on the vaccuum line.
