Okay so thanks in advance for the advice,
I have a 2010 dyna wide glide. last year I put a lot of money into the bike. Built it myself to spec down to inch pd on every bolt and .001 of an inch on everything. Here is a parts list
-107 S&S Big bore kit
-S&S 583 cam kit
-S&S super stock heads 89cc
-big radius 2-2 V&H
-cobra intake w/ k&n filter

So I know that cam with the set up is not really ideal with the heads but I wanted tourqe and low to mid range power and I figured the heads would let me get as much out of them as I could plus it is probably around 10.2/1 compression witch I thought would be good for longevity.

But the problem at hand, I originally had a V&H fuel pack FP3 with a tune sent from V&H for that set up. Ran like a top changed the oils after the break in period and no serious shavings or anything then ran for the rest of the season (late in the season) 600 so a total of 1200 miles on build.

I just had a local shop tune it ( wanted to get more and see what it did). They had me buy a power commander V that was compatible with there dyno jet (dyno). It put down 69.7HP and 99.3TQ. And I was expecting more

I picked the bike up from the shop and not even 10 miles down the road it got noise and lost all power ( I knew the front head gasket went). I was pissed.

He got the bike back to his shop and now told me the front cylinder lost compression. I pulled the map he put in before he got it back and compared it to what a dyno jet specialist sent me his map was significantly lower chart values. But is telling me he had it at 12/1 air to fuel. (Idk to much about it but I have my O2 sensors out) he told me in advance that’s fine. Another strange thing is he wants me to drop the fuel pack tuner back to the shop??

Main question I think he ran it lean and blew a head gasket. What do you guys think. Like it ran for 1200 miles fine. so could it have been Miss adjustment pushrod on valves or anything else the whole top end is brand new other then the rocker box covers. I am pretty knowledgeable with motors not the first motor I built. just no so much with dyno tunes

please help. Any opinions would be appreciated! I’m screwed now looking for legs to stand on if this shop try’s to blame It on something other then the tune. The only thing I can come up with is it ran lean and pushed a gasket. Hopefully didn’t warp anything.

if anyone has a bike with close spec and know what my numbers should be around that would be helpful as well thanks

Based on my interpretation of the information contained in your post I have this to offer.

Them requiring you to purchase the Power Commander V is a red flag right there.It is a outdated piggyback tuning device.
The V&H at least writes to your existing ecm which is quite capable.How much adjusting and tuning you can do with that one besides the maps that they offer is beyond my familiarity.

You are probably best inspecting the top end yourself, repair the damage and find someone who actually can tune a bike.

In the right hands,TTS Master Tune, Power Vision, and even Techno Research tuners will work with your existing ecm for tuning.These tuners basically flash the map that the Dyno Operator/Tuner creates for your bike build.

How to deal with the apparent hacks that dicked with your bike is something that (unfortunately) you will have to figure out.I wouldn't expect much in the way of good results.

Best of luck.

Thanks for the response I almost took it to another shop and had them fix it also get the correct dyno map flashed but then loose out on the 650 I paid for the tuner&dyno plus xxxx amount for if the heads need resurfacing (if need be) and repair then going after them for the cost.

I also feel as tho this shop is responsible for the issue at hand the shop is at a understanding and said he is going to tear it apart next week and call me with what he thinks occurred. I will post the fuel maps that the specialist send comparable to the one that was flashed also how crappy this dyno looked.

I guess I just am looking for reinsurance or any opinions for what else could possibly have occurred. I hate letting this shop work on it but I don’t wanna spend my money when they were the reason this happened.

Lean mixture combined with detonation or the Delphi fighting to take out timing. ths build may only have 10.0:1 compression but it will crank 207 with that short (too short) cam. Cam closes the intake at 18° ABDC. This is not a small motor you must let it breath if you want it to live and make power. A short as heck intake lobe and an overly long exhaust lobe is not a formula for success.

It's your fault,, not the shop.. dont waste everyones time playing the blame game... the cam choice was not even close to correct for a 107 with over 10-1 comp. This combo spells detonation and a quick death for something in the cylinder,, a piston if you used cast.

I’m interested on why you think this, do you have anything else to back your statement other then wasting my time TROLLING..

from my research s&s on there website put these cams thru a 110 motor so you telling me my cylinders have too much volume for this cam isn’t making sense here is the link.
S&S cams w/ dyno sheet

also for valve lift I understand the intake lift and exhaust lift obviously this cam is for tq here are all the chart values stock cam compared to all S&S cams

If the sns big bore kit and heads would be compatible with stock cams why not with S&S performance cams???

Thanks for the input, I guess where I’m confused is S&S claims the big bore kit up to a 110 kit for a stock 96 bottom end will work fine(after 110 the bottom end and flywheel will need upgrading anything bigger bc of stroke) meaning stock cam. My 583 cam has more lift that’s why I put heads that would be able to support the lift value. Here are the charts for specs on cam specifically


If I can also ask what cam would you run? I was looking maybe going with the woods 777 cams what’s your input on them?

Just trying to get a better understanding why would a stock cam with these Jugs/Heads work but not a performance S&S cam??

Wait a second... when TT tells you that you made the wrong cam choice, you get pissy?!
Then when Don tells you the same thing you start asking for more advice?!
Don knows his sh!t but so does Terry.

grrrrr... freakin' newbies.

EDIT: grrrr... freakin' newbies that ask for advice and call the expert a TROLL when told the truth.
Not all newbies. Most I welcome.

how is me sending chart values and asking questions on explaining more of his statement because I’m trying to understand more also providing my thoughts.. not trying to be pissy

You come into an unknown place, don't bother to get to know anybody, and just expect top notch service at your feet. Then you start calling out one of the sites top contributors as a troll.

You have just convinced me (and maybe some others) that your self-centered attitude may be a big factor in your problem.

The only reason I approached the response like that is because he said( stop waisting everyone’s time playing the blame game ) And then I replied telling him to give more feedback on his accusations. Bc it still doesn’t make sense to me.

Last thing I’m doing is pointing fingers at anyone, I just was interested if anyone else had similar issues. That what I thought these forums were for!

I’m not here to get to know anyone! I’m here to get some advice from fellow riders. As I would for any riders if I had the advice.

I don’t know anyone here, or who is just coming in like Tom and just making accusations telling me to stop playing the (blame game) and wasting peoples time.!

so my response was help me understand and explain in more detail that’s what I thought this forum was! Helping each other out. I can go on every forum on here and say well such and such is you problem and it’s your fault and then not
respond.

Getting to know real people is helpful cause there are too many armchair experts that don't know crap.
They just repeat the internet over and over.
One needs to learn to separate.
Let's wish the student well, hope he pays attn to those that can offer real-life experience.
First off, I doubt the dyno blew anything up, it would have done so on the street too.
If he has too much timing, be happy it is a head gasket and not a hole.
Timing is the function of a lot of variables.
Blame is a function when all the facts may not be understood?
We have all made mistakes ..some of us some pretty big doozies.!
But that is the university of hard Knocks. we learn or quit.

You will find this is a helpful place and has a few butt heads.
I have been known to walk both sides of the fence.

Tell you the truth it mite be worse not gonna know until late next week when the shop pulls it apart.

Do you have any opinion on why this cam is dynoed on s&s website on a 110..I have listed above on a reply message. I will not quit and I will figure this out.
