runs fantastic once it is warm.

 

I was only replying on how to fix a CV carb.. And that would be with an S&S E.. lol.. That's all..

 

Yup possible choke problem.,although i will say replace the plugs also it makes a difference. Harleys aren't like cars they need plugs sooner.

 

Brand new choke cable and plugs. I'll put another set in see if it makes a difference but these only have Maybe 100 miles on them if that. Ill prib order another choke cable too while the carb is still out just to see if this one's faulty.

 

Well, you wouldn't believe some who pass thru here... no offense intended.

Vacuum leaks are 90% of all problems with a CV but it doesn't sound like it on yours. Changing the o-rings at the manifold/heads is always good insurance, so no wasted effort there. They can leak 3 ways, when hot or when cold or all the time. If it starts, idles and takes throttle OK when warm, the float level is probably close enough and another indication of no serious intake leaks.

You've cleaned it (?) but I still wouldn't rule out the starter circuit being restricted. If the starter valve (end of cable) is installed, you can't blow thru that port. (arrow) Needs to be blown out from the seat of the starter valve back thru the port in the bowl and back again. If that's not it, the only other things that would cause this, low compression or low ignition timing. Just guessing compression is OK. If the timing is set low, they will run good, but fuel mileage sux and definitely cause hard cold starting.




No matter what, you should never need starting fluid to light off an Evo no matter how cold it is.

 

I don't know your experience level with a CV so I am going to rattle off a few of the basics...

The slow jet has really small holes, make sure that jet is clean and clear. Same for the emulsion tube. Lots of small holes. Gotta be able to see thru the jet holes and make sure they are clear. The passages that feed the idle and transfer ports with air and fuel need to be clear (the air and fuel are separate passages). The only way to confirm that is by watching carb cleaner spray go thru them. Should do that with all the carb passages.

Is the needle jet installed properly? There is a wrong way and many don't realize that they either lost the needle jet or installed it upside down. Check the slide diaphragm for holes. Check the accelerator pump diaphragm. Does it squirt fuel? Usually giving the engine a few squirts from the accelerator pump with the throttle is enough to get it fired up. The choke (actually enrichener) helps the bike start easier, but the squirts from the accelerator pump are usually enough.

Does the idle mix screw have the spring, flat washer, and the O-ring? That O-ring gets stuck in the bore when you remove the mix screw, and people think it was missing, so they install a new one and now the idle mixture is all effed up because you don't have a good seal or there is a blockage from the old O-ring still being bunched up in the bore. Forgot to mention, is the idle mix screw passage clear?

You never mentioned if this is a new issue or an old issue. That information would help. Regarding my question earlier: Was there point since the cam was installed that the bike started easily? Again, new problem or old problem?

 

Everything checked out, but its a old issue its been like this since I got it. That being said I bought it last year right before snow fall and I put it up on a stand. Pulled everything apart to do the clutch basket bearing, clutch, spring plate, fork seals, neck bearing and more and put it all back together and no matter my setting it's been an issue. I like I've stated before I'm running adapters for a s&s intake to the cv so im wondering if the adapters are leaking of if the adapters push the carb out too far to the point where the carb can spray the fuel far enough into the combustion chamber (leaning toward that or intake leak).

 

Have you checked timing?

 

Everyone talking about the choke or enrichment system has me remembering on my 1998 Dyna there was a recall on it. I purchased mine new and had the recall done but it’s been too long ago for me to remember specifically what was done. Not sure if the recall was only for 1998’s of more years involved but maybe look into that?

 

I havent but wouldn't timing be an issue constantly not just on start up?
