Yup, I ended up just buying a new set of gaskets for everything on that side, I plan to pull everything down to the manifold and replace all of them in there. Hopefully that'll clear up my issue.

Definitely nice to not have to worry about whether or not it will start on a cold day, too.
I never had any trouble starting my carby Sportster.

More so talking about my old Honda Shadow I had in college, it sat outside and could be a reaaaaaal pain to get going in the mornings sometimes if it was really cold. More than anything I was referring to the fact that I can start it and go with EFI, don't need to wait for the bike to warm up like you do with carbed bikes. I guess you can do the same thing and take off while it's still choked, but I just feel better about doing it with fuel injection is all.

Sorry I meant forums for glide bikes and touring bikes, stuff that actually does have tbw. But I would think with a throttle position sensor on the sportster as well, it might work the same way to reset it.



By the way, haven't had a chance to ride the bike today, so I am not sure if trying that reset on the throttle position sensor did anything... Hopefully I'll have a chance to give it a ride tonight or tomorrow.

FYI - It is entirely possible that the RPM's not coming down like normal is caused by an intake leak. I had a very bad intake leak and the bike would take a minute or so to come down to normal idle. Used intake cleaner around the intake/head connection and the RPM instantly changed, confirming the issue.

I'm not sure why, but that connection between the intake manifold and heads seems to cause me issues. I would consider checking for an intake leak there.

I had the issue one time out riding/camping with Sprink and Sportster Paul. It got so bad it became hard to ride safely (can't engine brake when the engine essentially revs with a closed throttle...). We stopped at a dealer we happened to be near and replaced the gaskets in this parking lot:

Yup, that's pretty much the conclusion I've come to as well. I ordered replacement gaskets for everything up to the heads, and plan to swap it all out when they come in. Mines not so bad I can't ride right now, but I was planning to pick up some intake cleaner and see for sure if that's the issue. Thanks for the tips!
