improper install of TW-222 cam, potential problems ?
I have only owned the bike for a little over 2 years... and I did not get to meet the original owner. (Health issues) . I purchased it from his best friend, and even though the bike was Exceptionally Clean, (and quite obviously very well maintained), I did not get the service records. (they were apparently out of state), where the bike originally had come from.
As far as the possible Tuner issue, I suppose that could be an issue but I do doubt it, as when the cams went in last week, I also stepped up and purchased the Power Vision 1B, and the tune from Fuel Moto.
I purchased the bike just over 2 years ago with 19,514 miles, and yesterday I was at 27,517 miles.
Thank you for the suggestions.
I have also read today about others having similar issues with "IAC valve" (?), so I need to check into how to determine if this too might be a contributing factor.
Stock piston / compression.
and if it might matter, 2007 was the first year of the 96"

I will check that out.
I am betting they don't and offer that as proof of the general statement that true duals are not top performers regardless of brand.
Now if you have real data that shows Brand X true duals are the performance equivalent to Brand X 2-1 or even 2-1-2s, then I will thank you for the lesson learned.
Proper length, diameter, and placement of steps is the difference.
FM actually sells them now, btw.
Below is a link with a direct comparison on the same bike belonging to djl and tuned by Nick at Shamrock. It's why I chose them in my 107 build doing 127/126. Like djl, I don't care for the looks, sound, and hiway drone of a 2in1.
There is only one 98 build I know of making more power than this one.

theres an equally modified/unmodified comparison that has very close peak numbers. I'm no expert but from what I've seen/ read the more you modify the engine the more exhaust comes into play. Of course not all systems are created equal either. Take an El cheapo 2/1 and put it up against a true dual system with stepped headers, anti reversion baffles etc and it's not even going to be close. Theres lots of variables with exhausts and the most important part, if performance is your goal, is to have all of the parts play well together.

Actually, depending on which 2in1, the Pro Streets will perform way better. Especially the short, megaphone one.
A 2in1 isn't good just by virtue of being a 2in1. Way more of them suck than are good.
True duals don't suck just because they are TDs. But very few manufacturers spend the time and money to make them perform well. The right length, diameter, and placement of stepped duals will outperform most pipes.
I can tell you there are very few 2in1s that will do what the pro streets are doing in my 107 build. While the low end isn't their strong suit, there is no reversion dip like a lot of 2in1s would have and most TDs have and the Pro Streets make awesome mid and upper rpm power. More than many 2in1s would. How many tc 107s are there doing upper 12Os squared? You will find most all of them struggle to hit 120hp. How many 98 builds are doing 118/116? Not very many that's for sure. I've seen one other.
2in1, 212, 2-2, it doesn't matter. It's not what makes an exhaust good or bad.
I use to think the same thing about TDs. Not anymore. I run the Pro Streets in my max effort 107. If they sucked they would be gone in a heartbeat.
Here's the 98 build. Red is the Pro Streets, Green the Fatcat, Blue is the Python, an older version of the pro pipe.

The Best of Harley-Davidson for Lifelong Riders
I am having a few upgrades installed on my '07 EGC. it already had a high flow air cleaner, Reinhardt True Duals,
(O2 sensors were removed by previous owner when the "Stage one" was installed),
and a PC3 controller.
The PC3 in now replaced with with a new Power Vision 1B, and new map from FM, to accommodate the Wood TW-222 cams going in.
After getting the TW-222 cams, and FM's Power Vision map installed, we were getting a check engine light and a 1353 code. (Front cyl combustion code). Bike idled fine, and ran "OK" up to about 4000-4200 and then started to stumble/gargle/ ran like crap. Also, the brand new spark plugs showed fouling/black deposits.
After a few conversations with the gentleman doing the install, he agreed to pull open the cam chest to verify the cams were installed correctly,... at which point, we determined, that he had in fact, installed the forward cam "one tooth off". (Yeah not good, but "it can happen").
as of last night, it is now getting corrected, and it should be back together in the next day or two.
So my questions now are,
Do you think that there is a chance of damage to the engine that I will need to check for ?
if so, what should I check ?
Compression check is showing 200 and 210 psi, so I don't "think" there will be a bad/bent valve issue.
is there anything else that I need to have him check and verify ?
The other upgrades getting installed at this time is:
Pro Action fork kit,
Ultra Cool 3.0 Dual Fan oil cooler, (I live in East Valley Arizona) so it get DANG Hot here.
in dash Oil Temp Gauge
1 1/2 " front fuel tank lift
Thank you for any replies and advice
Cheers

Let us know how many different pipes you tried on YOUR build and the results, after all it was MAX EFFORT. If you didn't try any other pipes you have no idea what any of them would do.
