Issue after replacing intake o rings and spark plugs

[KG]

Intake o rings leaking. So changed them and the spark plugs and used digi synch to set carbs.
Runs a lot smoother and seems like rpm are a little lower at 65 before was just over 3000 now just under 3000. No more loping while coasting at slow speed

Feels like I'm getting more heat out of the left bank
See difference in plugs they are 2 years old and just got back from 800 mile trip.
Why the difference in heat all of a sudden?

Not sure what's going on but....there's no way anything you could do tuning wise could affect your rpm at a given speed. The only way to do that would be to change tire size on the rear tire. Your plug looks perfect so not running too rich or too lean. If it's running good you are there. Just get out and ride.

Are you saying that your Left Bank is hotter because the plugs look a little different? Or is that something that you can actually Gauge by external temperature? I'd say you're right the tan one looks better than the other one but it's hard to imagine that all three plugs on one side are going to be exactly the same while all three on the other are different.  Perhaps something either in the intake on that left side or the exhaust on that left side maybe somehow restricting and making it run a little leaner? Just a shrot in the dark really

You know after taking a second look at it the tan plug actually has some white crud built up on it doesn't it that's probably not good

I know you can't change rpm except for changing tires or gears but before it was on the right side of 3000 rpm now it is on the left or lower side still touching the line just now the other side. just enough to tell it moved most likely now the engine is not trying to overcome the massive vacuum leaks. one vacuum line to pair valve was cracked and separated in half



you can feel more heat off the one side and when I put my feet on hwy pegs you can tell one valve cover feels hotter.

one bank had the dark deposits the other bank was nice and white. those plugs were in the bike when I got it two years ago

never sits as I ride anytime there is not salt or ice on roads. use nonethanol gas when I can and on long trips will use b12 or techron cleaner

will ride today and check with temp gun

Don't know if that's a before or after picture, but you're missing some bolts on the intake tubes.

Missing bolts hold the chrome engine covers on. Had to take it off and decided to snap a picture

Recheck today and found front and rear cylinder on that side go to cruise control and those hoses met at a tee fitting which the hose had come off. So those cylinders had a bad vacuum leak

I repla e my rings as soon as I see the slightest bit of seeping. Yours look to have been bad for a long time.

Glad you were able to get it resolved. Have you given any thought to de-smogging it? That eliminates a bunch of the problems associated with vacuum lines. Pretty simple to do as well if you do the "simple desmog".

One issue with chrome covers on interstate as the pods and covers hide everything. Only reason I found the leaks is a fog light bulb burned out and I had to pull the pod to replace it

Desmogged a long time ago but cruise requires vacuum lines

Glad to hear it! Good point too. I have installed two cruise control systems, and will install my 3rd tomorrow. CCS100 definitely requires vacuum lines.
