Time for a big bore kit, want to keep the reliability but want more hp/tq.

1. What setup do you recommend? 107 or maybe 110 Fuelmoto? Others?
2. Installer in the Scottsdale/Phoenix area

Want to do this right the first time, keep the reliability, not so concerned about the cost.

 

If ya don’t care about cost, S&S 124

 

Or a custom built 124. Or a custom 110. Or an S&S 111. Or a fuel moto 124 (should be shipping with just a few weeks).

Truly, if the only parameters are that you want it reliable and cost is not an object, you have a gozillion options.

 

So much of what you decide should be based on how you ride and what final goals you have for that riding. I wanted exactly what you stated above, high reliability with lots of power/torque, that wouldn't shake my teeth out if I ride all day long and put on an average of 250 to 300 touring miles in day. It didn't really matter to me if it did a quarter mile 2/10ths of a second faster than the next guy or not, as long as it had that pull to make me grin ear-to-ear.

I've got all the power I need and then some and have had my 107FM kit for three seasons now, about 24K miles. Total reliability and pure heaven to ride. FM doesn't over sell, so they won't push the level II heads or the Target-Tune option (for real time, wide band dynamic tuning) but those are options you should definitely add to the build kit.

I know you don't worry the cost, but going above the 107/110 kit means doing lower end work on the crank which adds a whole new level of cost to the build for a level of power you probably really don't need and won't use, unless you are a power mad speed freak or just like to do 10 second quarter miles.

The FuelMoto kits are very reliable kits and they continue to work closely with Woods cams to get remarkable numbers out of the 107 builds. Since they do so many of them with every variation of intake and exhaust system they can provide an initial base map that is almost perfect before it even goes on the dyno, getting the Level II heads gets you a gorgeous flat power curve to red line.

Can't beat the quality of S&S but that solution will be more expensive.

One thought, would be if you are going to have the work done by a reliable high reputation builder, talk to them and find out what they like to use. Giving a builder a kit they're not familiar with probably isn't a good thing.

If you've got the time and the means, trailer your bike out to FM and enjoy Wisconsin for a couple days. You won't be disappointed with the outcome.

I had the same question the other day on the mechanical section of the forum. I am going to be doing the ss 110 kit this spring. My builder says that it is reliable and will get the HP and TQ that I am looking for. I am keeping the stock heads for right now but if you decide to do your heads you will get more out of the motor.

Happy building!

I wanted the same and went with the S&S 124. Rock solid bottom end and great power for speed or passing when touring loaded up. I ride approx 20K a year and tour across country yearly. Never had an issue with gas or anything. Do it right the first time whatever way you choose to go....Good Luck.

 

How many miles on that motor now NorCal?

OP, if you’re looking seriously at the S&S you’ll find they make two versions of the 124” motor. The differences are in the cams and the pistons, which leads to one engine making greater horsepower from a higher compression ratio. The conventional wisdom is that for heavier touring bikes the low compression version is preferred. However, NorCal went with the higher compression version and, as you can see, has been very happy with it as a touring power plant.

Fun choices!
