Anyone running Woods 777 cams in their Stage II 103's? My indy shop is recommending these, for my 2011 SG trike, with good air cleaner, Power Vision tune, and keeping my V&H Power Duals and Monster Round mufflers. We have three trike dynos in the area and my builder would be fine-tuning the build, on one.

 

I've got a 777 in my '14 Ultra Classic. Heavy breather A/C, D&D fatcat 2 into 1, Powervision.

Band is definitely higher in the RPM range. Definitely see a difference in top end power.

I think it depends if you"think" you may do more. Seems just slightly margin of gain over 222 or 555 without adding compression. Now what the FM team shows, if add some compression the 777 really separates from the other 2 cam options.

I talked to FM and Bob Woods, told them where and how I ride, and they both recommend the 777. I'm happy with it, but like always want a little more now.....

 

 

Is the bottom end a little weak? Dyno sheets I've seem for a combo I'm looking at seem to suggest I won't lose anything, down-low, and it looks like the power curve comes alive, at 3k or so.
Your bike has a killer idle.

 

I wouldn't necessarily call it weak, no engine does well when lugging it low RPM but it definitely doesn't like it.

I would call it more of a "delay" rather than weak. Turbo lag is a little too exaggerated, but when the RPM hits the power and it definitely hits harder than stock and all the way near redline it feels.

Not having ridden one with 222, but that cam seems to come in earlier and live in the lower RPM s. Probably fits for riders just needing little more umph pulling out and getting to speed limit and probably less downshifting when passing.

I tend to hang out on the other sides of speed limits and shift above 4k a lot of times. Especially when wife is not riding.

Where you located?

 

I don't feel there is enough compression on a stock 103" to make the most of the TW-777. I have TW-222 in my 2014 SG and it rocks on the low end and is strong up to about 5000. Best overall for a standard Stage 2 build, don't over think it.

 

I agree with Tully's statement. For majority of touring riders, 222 is the best option for stage 2. I watched and noted my shift points for about 2 weeks of riding before finally deciding on the 777.

I am now considering what next steps are, either adding compression with 107" kit and heads, or selling bike all together and going to 114 stage 2 M8 bike.

 

The 222's are what I wanted, to start with, but my builder was pushing the 777's. Since they have built a ton of fast Harleys, it was something to consider. However, my trike has pretty tall gearing and is obviously no lightweight, I still believe either the 222's or maybe even 555's would be a better idea. Thanks for the input, guys. I appreciate it.

Tyler, I live in Central Texas, about 35 miles north of Austin. My engine builder is Big Dave @ Triple Nickel Cycles, in Liberty Hill. Jamie @ FuelMoto knows him, well.

 

As said, depends on how you ride, but I would personally never recommend the 777 for a trike

 

Best thing you can do is go look at the fuelmoto dyno charts. They have a great comparison between many different cams in an otherwise stock 103. And take note of the RPM of peak torque, and what the Tq is at say 2500-3000rpm where you’ll typically be cruising at.

for a heavier bike/ trike I would suggest the 222 or 555 woods cams over the 777. Also at something like the Fueling 525 or 543’s. The 222’s (Going off fuelmoto info) have basically 100ft/lb+ from 2k RPM on up with peak at 3700rpm. The 777’s don’t cross over the 100ft/lb mark until 2900rpm, and peak at 3850rpm. With the 555 somewhat splitting the difference but a little closer to the 777 curve. High HP/TQ numbers mean nothing if the power isn’t where you need/ use it. The 222’s will be a cam that allows you to roll on the throttle in 6th on the highway to pass a car, the 777’s will be a cam you drop a gear and then crank the throttle with to pass a car IMO.

I personally am having the Fueling 543’s put in my 103 dyna as I was looking for optimal cruising and mid range power. Haven’t ridden it yet, but fuelmoto’s chart shows peak Tq at 3.79 so basically 3800rpm for the 543’s, and crossing the 100ft/lb mark at about 2800, and 95ft/lb from 2k-2800.
