Very Nice!!! Not sure if CVP has a phone number, but if they do, I would give them a call. YD

 

Maybe I'm a dunce, but I haven't been able to find the PM command/option on this forum yet - help. I appreciate your offer and would probably choose the needle on the left as it appears to have a much different taper than the needle I have. But I've probably missed the morning deadline.

CVP doesn't list a phone number and continue to say they are down for maintenance.

 

Ya I'm at work now but I'll still send it to you tomorrow if you want to save yourself a couple bucks and try swapping the oring and needle. If that needle is the problem I'd think you could adjust this one and get it running fine.

Any luck checking the accel pump?

It's not letting me PM you either. You have to have 10 posts before it's active

 

I'm out of town working right now and will check it all again Sunday. I'll try to get my post count up ASAP.

 

If you get me an address I'll get it in the mail tomorrow should get to you by Monday I'm sure.

 

I thought about ordering OE needles 27091-88 from the Sportster and 27186-92 from the Dyna and a set of jets.

(Shameless effort to get post count to 10)

 

Almost there! Def need to recheck the intake seals too. Could have a leak on one side

 

kp... I just finished reading your "jetting" thread https://www.hdforums.com/forum/evo-c...8-jetting.html and it sounds like you had most of the same symptoms as me. Are you saying that the final solution was a new ignition module?

Like you, I have two coils (one OE HD and one aftermarket) that measure 10.8k on the secondary and 2.9-3.0 on the primary. While both of these are in range, does that necessarily mean that they are "good"? There's really no way to test an ignition sensor and module for sure other than to change them out for something else. My bike has 23-year old OE ignition components installed. I don't mind replacing these things, but don't want to if not absolutely necessary. I have this secret desire to keep the bike as stock as possible just for the sake of it.

I also took special interest in the mixture screw having no impact at any setting, which means that fuel must be leaking through. I would love to find the root of this in my carb, which might explain the dismal MPG.

I still can't find a PM option, so I'm going to do some posting tonight.

 

No I had different symptoms. My cam sensor was bad which didn't fail like everyone else's it failed at high RPMs. You could pop the timing cover off and check the cam sensors condition I did that with the help of a few on a diff thread and it tested bad but I can't say I understood the readings I was getting. You can check your cam sensor using a heat gun and cold compressed air. Youd idle the bike then blast it with heat gun or hair dryer to get the sensor hot and see if it starts cutting out. Oddly mine passed the heat test. Also. When my idle mix ezjust fell out it ran more like your describing it was backfiring hard out the pipes and surging at steady throttle. It wouldn't idle at all though where I think you're still able to idle when it acts up.

 

Read Texashillcountry's thread title cam sensor question you'll see DR Hess instructions on testing it but you might get bye with a quick heat test if that makes it fail right away
