When I got my Kingpin last year it really seamed to run a little rough at idle and it seemed that the only way it would idle properly was if I kept the fuel enriched on. Well that all changed today. With the help of a YouTube video I watched from the Vic Shop I pulled the tank and cleaned out the throttle body, buttoned it back up and started her up.
Also, when I had the air box cover off I also checked my fuel enricher adjustment and found it only opened ever so slightly, there was so much slack in the cable I can't believe it moved and opened at all. Before when I started the bike it idled only around 800 rpm and that was with the enricher turned up. Now after I started her it ran about 1400 rpm with the enricher off. I adjusted the Idle to 1000 rpm and took her around the block and it feels smoother and more responsive, I can't wait to open it up on the highway now.
I was running late today getting it back together and I didn't have time to pull the plugs and check them yet, so that's next. I have just over 14,000 on the bike now so I'm not thinking they need changed, but if it wasn't running right all that time I'm thinking they might, we'll see. Ready for the summer now!

Quick FYI - It's not an enricher. It's a fast idle lever (per service manual). It's just to hold the throttle open so you idle faster. No enrichening of the idle mixture.

If you used a lot of cleaner to clean the throttle body for sure get new plugs. You might even want to get new wires cause factory one are not that good. All so check oil if you used a lot of cleaner it might be over full.
I did change the plugs with new NGK's, the old ones didn't look too bad. Is there a good vendor for the aftermarket wires? I was at a dealer last year and they had a blue set I thought would look good but they were liste for an 08 & up so I didn't get them.

I was wondering about that. It makes sense, Thanks.

I changed the plugs and the old ones didn't really seem bad. Didn't really notice a difference. Also what is a good vendor for plug wires. I almost bought a set last year at a dealer but they were listed for an 08 & up. Didn't know if there was a difference so I didn't get them.

Sounds like the tb's were never cleaned, must have been gunked up pretty good. If it idle was at 1400 after cleaning the previous owner must have kept adjusting the idle up as needed. You'll know when they need cleaning as the idle speed drops.
