I reread your post...the plastic black nut on the outside of the cable (the part that's behind to the choke ****) may need to be tightened. do it by hand, do not over tighten.

 

I agree with letting the engine warm up, however, I don't think it should be done with the enrichener. I use the enrichener to start the engine, then, I open the throttle a bit, while pushing in the enrichener ****, keeping the engine revving about 500 rpm above idle (so around 1400 - 1500 RPM). Then I lock the throttle with the star wheel, and let her warm up that way for short period, while getting my lid, gloves, etc... on.

Cheers!

 

That's how I do it also. Sometimes I don't even need the enrichener. Even when cold (summer cold not winter cold). A couple of twists of the throttle to give it a few squirts of fuel then fire her up. Throttle might need a little feathering, but I bring it up to about 1500 rpm, lock the throttle and let her warm up.

When the engine speed starts to increase on it's own, I back it down a little and use that as a signal it is telling me it is warmed up and ready to ride. YD

 

 

Over the years the enricher cable/adjust just wears out. maybe time to replace it.
Nothing wrong with pulling enricher starting and ride a bit until it warms up that what it is for.
EVO should be warmed up before you roll on hard

 

My fast free fix was to slice open the gel cushion from a gel pen into a sleeve, then cut it to proper 'wide open' length....works like a charm! 2 picks in my profile....

 

The cylinders actually " grow" in length with heat. So letting the engine warm up before putting a load on it helps prevent getting cylinder base gasket oil leaks. Especially with the evo engines, it's a fairly common problem. Mildly hot to touch is fine. YD

 

I actually only let mine warm up for about 30 seconds....as long as it takes me to strap my helmet and gloves on...this keeps it 'wide open' for those 30 seconds though, until i have a free hand! And then i regulate it with my throttle hand as I Get.

 

I'm sure most know the choke is not a choke but rather a diff. passage or jet to pull fuel from the carb bowl, as so ridin with it pulled out will not limit the air pulled into the intake. as for how long to let warm up I think depends on how you ride and where you ride, my self I start with the choke out and very little throttle to get to a street where I throttle up for speed this sucks the **** in and if I hit a light I may have to pull it out again if not the bike is warm by the time I think about the choke again and the **** has returned to all the way in, if you are the kind of rider that twists the throttle to warm the bike the choke will suck back in as you rev it. I put a new one on in 2001 still workin the same ohya I put the second one on in 2001 because I didn't understand, do not over tighten

 

I hope we've solved the choke **** problem! As for warming up or not I'll pull rank here as I can say that for over 50 years I've never warmed a bike up for more than a minute or so, including winter riding at well below freezing. In other words there is no 'right' way. Just fire up, let her settle and get moving - gently obviously for the first few miles, then ease up to speed as she gets warmed through.
