2014 Harley FLHTK Twin Cooled testing & info by Fuel Moto
#531
Our cam testing from last week is finished up on the 2014 FLHTK. Tested the Wood TW-222, TW-555, & TW-777's vs stock cams. Results show very good gains with each cam. Each cam was tested with the same combination which included the Jackpot 2/1/2 head pipe, Jackpot mufflers, FM Pro billet air cleaner, and each setup was dyno tuned with Dynojet Power Vision.

jamie head gasket
jamie what thickness head gasket came with the 2014 and what thickness did u use when u had the heads off.. i had changed my engine over to 10.5 pistons and mva 95 cc heads before u had made the 107 kit so popular. wondering what gasket u have in and I am considering using a woods 222-555-777 in my engine cant afford the head rework and change again to b model heads .
with the .045 gasket in with 12 cc piston 95 cc head in my 103 i get 10.2 static-- if I had put the .030 it would be the 10.5:1
the 222 i get 9.62 corrected ccp 201 the 555 i get 9.36 corrected and ccp 194.3 the 777 i get 9.32 corrected and ccp 193.7
before i started to learn how cams change the corrected and ccp i had se255 in bike ran good but the engine felt different , not as smooth I believe this was the super high ccp at 208. and corrected at 9.9. I have andrews 32 in now but the low end isnt there like the 255 was corrected 9.14 ccp 189 .a tuner had told me he wouldnt even touch the bike when the 255 in saying there wouldn't be much he could do and I needed ccp to be around180-190 range.
not that I have explained all this, this is why I am asking what gasket is in the bike with all the cams u tried. looks the 555 or 777 puts me 193-4 range and may be usable. its a learn as u go assignment, sure is lots to learn . I tried a few different pipes I had around and boy does that change my low end response, I'm sure the huge ports in the heads have a lower velocity than the stock reworked heads have at lower rpms.

Next up for our test was a quick muffler swap. Note the stock mufflers on the new 14 bike are the same as previous models. Slip on muffler applications carry over from previous models.
Also note the factory catalyst head pipe carries over from earlier models as well
We installed a set of Jackpot 4" Dyno Tuned mufflers. We are starting with our most popular muffler, it is a solid performer and our standard baffle is about middle of the road as far as core size, however due to their specific designs they are on the lower side of the dB scale by comparison to other similar mufflers especially on the stock catalyst head pipe.
We did this test back to back to the stock test, in the time it took to change the mufflers. No additional changes were made, simply the muffler swap. We picked up Hp and Tq over the entire curve, in some areas more than 10%. Ended up 79.90 horsepower & 98.98 torque. Here is a comparison dyno chart:
The fact that it responds to a more free flowing muffler is a good sign, we are very interested to see what replacing the catalyst head pipe with our Jackpot 2/1/2 will bring. At this moment we are current working on initial Power Vision functionality and in the meantime will work on getting some maps done for the Fuel Moto Micro EFI Tuner which is already a direct fit for the 2014 bike.

One thing I have never seen in this or most other upgrade threads and comparisons of mpg before and after. While some may want more performance I have seen cases of huge decreases in mpg (not necessarily FM) and if that was known beforehand it might have some influence on what changes were made. Any thoughts?

Any thoughts on this? I know for some its not a consideration but I have seen huge decreases in mpg with some modifications and this is a topic not discussed enough IMHO?????

BTW, I just bothered to calculate my mileage for the first time this weekend. On a back roads, 160 mile, 4 hour, 25-55 mph ride I got 42 mpg. That's with a Stage 1 AC, 4" slip ons, and a SEPST. Bike has 2100 miles.
