I have a 2011 Electra glide classic. 96in with Andrews 48 cams dresser duals and fuel moto outlaw slipons. Bike has 58000 miles on it. Runs perfect I’m considering doing a fuel moto 107 kit but still on the fence. With those miles on it would the added power be just asking for stuff to start breaking? How much more power will be noticed. I ride solo most the time With a few day trip 2 up with my wife. What are y’alls thoughts on the 107 build vs stock with cams. Should I worry about the crank with the miles and the valves and valve seats?

 

I'm in for answers to these questions too. 13 SG. 103 with stage 1 53k miles.

 

Whichever way to go ditch those dresser duals.

 

How come? I like the look and sound but don’t know that much about the cons of them

 

Awful for performance. The V&H dresser duals are the worst performing of all the true dual set ups as well.

 

I had Fuel Moto do my 10 Roadglide with their 107 kit last November.

Bike had 33k on it at the time.

I, like you, had a 96 with Andrews 48s and was clocking about 98 ft lbs of torque. I was tuned with the fp3 and ran V&H true duals with cobra 3.5 slip ons.

Bike ran solid got great fuel economy and sounded good but at the end of the summer before I upgraded started to get hot and was down on power.

I scheduled my appointment with FM, drove up one afternoon before the scheduled day and dropped the bike off right after they opened.

FM completed my bike that afternoon and called saying I could pick up the next day.

I did 107, level b heads, woods 777 cams and FM air cleaner.
Had purchased a PV before the upgrade dumping the FP3.

I ended up right at 123 ft lbs of torque and around 115 hp.

Bike runs great, fuel economy is Rock solid, engine no longer gets hot and I have power in any gear across the power range.

All total I'm in, including the PV around $4K.

I'd do it again, in a heartbeat.

PS, I still have original comp, and have ridden over 10k this summer after the upgrade and the only service issue I have had is a failed front fork seal.

My experience, yours could vary.

 

FM offer a range of tuning options, so if you decide to go with them then ask their advice on ALL aspects of your upgrade. That will inevitably include a fresh exhaust, so include that in your budget.

As for true dual exhausts, that is how most twins came in the past. Then during the '60s IIRC BSA discovered by chance that adding a balance pipe between the separate exhausts improved low/mid range performance significantly, over separate pipes. That is why today every twin-cylinder bike made comes stock with some sort of siamesed system, including our Harleys. So to get the best out of your upgrade, go with the flow!

 

I did my 107 build the winter before last. with doing the heads I ended up with pretty much the same number as everyone else, 126tq/116hp. I thin the longevity is in how you drive it if it is put together correctly. I haven't head any issues with mine.

I upgraded from a 96" with a 48h cam as well.

 

I think longevity is a roll of the dice no matter how you drive it. Are you going to spend 3 or 4k on your engine then drive like grandma heading to bingo? No. I'm not saying doing clutch drops and drag racing from every stop light either. I have an 08 cvo road king that had 43k on the clock. Crank runout had been holding steady at .003 and had good oil analysis. I had a good stage one setup but wanted more. So I got heads and cams. Bike ran great. I dont abuse my bike but i do make use of the power. All was well for 7k this summer then I felt some me vibration and it was downhill from there. All I did was hit the rev limiter in 4th gear passing a car. That's all it took to shift the crank. Found the big end connecting rod bearings were on the way out too. Just got done putting one of these in from darkhorse. Bike is so smooth now. Now I'm ready t9 build a monster. Build it ,enjoy it, break it, fix it.

 

Thanks for the information. I don’t ride too aggressive but do like to twist it every now and then, but rarely exceed 4500 rpm my main reason would be to get a little more power and i like tinkering with stuff. Would I be better with a stock head pipe than with the duals? I really don’t want to change pipes these are less than a year old
