107 kits, so many too choose from, whats the difference?. What should I look for in a quality built kit?, bore , coatings, pistons?
I see kits starting from $500-1300 approx. I wanna save a buck, but I don't want to sacrifice reliability or quality? I only want to do this once.
Which to stay away from?.
Should I just piece this out individually?
Thanks in advance for any suggestions.

 

If it were me FuelMoto would get my business,superior product stand up company and customer service is next to none. And they do a mean 107.

 

You'll get as many different answers as there are different options. I went with a S&S kit as there aren't any decent shops nearby me and I am able to do the wrenching myself with my mechanical trade background

 

I think the boring method and the Pistons used would be the most important factors for the 107 portion. As far as headwork alittle reading will go a long way.

 

Which boring method , and pistons would you recommend ?, are cylinder coatings necessary ?

 

WE were one of the first shops in the country to start boring the 88"-98" back in 2006, and in 2007 we were boring the 96" to 107".
Wiseco, the worlds largest powersports piston manufacturer supplies us with proprietarty piston/gasket sets.
With happy clients on 4 continents, we'd be happy to lend a hand with a complete kit.

At this point, I think you'd be way ahead thinking of this as a build, rather than a "kit". There's no need for new cylinders, your should work fine. Spend that money on having the heads done, 'cause you've got them off anyway. Follow me so far? Good. You've got the motor half way apart now, and you can have the heads/compression set pretty much anywhere you want, so ask yourself HONESTLY what you want to end up with, and work with your builder on which cams/headwork will suit you best. I know it adds up quick, but in the long run you'll be much money and time ahead, and you'll be REALLY happy with the results. Ask me how I know...

Oh, and BTW, there are some sponsors here that do this ALL THE TIME. Talk to them, and you'll be way ahead.

 

For those interested we just released a time lapse video of a full engine build at Fuel Moto. We started with a customers completely stock 2013 Ultra and installed the Fuel Moto 107 big bore kit, FM Level B CNC heads, Wood TW-777 cams, FM/AIM clutch, HPI 55mm throttle body, Jackpot 2/1/2 head pipe, full size X over, Jackpot 4" mufflers, Dynojet Power Vision & AT-110. Total engine build time was 6 hours 23 minutes from teardown to engine start. Base dyno numbers were 71Hp/88Tq when we started, final numbers after the build & full dyno tune were 116Hp/120Tq, an increase of 45Hp/32Tq! Hope you enjoy the video

 

107" engines combos in single cam since back in the 1990's that constantly, easily, showed 120-5 hp/120-5 ft/lbs in carbed form, 4" stroke T/C combos using Axtell 4 1/8" cylinders, some with S&S Twin-50mm throttle bodys, and now, after 2007, the 4 3/8" crank-equipped engines that allow almost anyone, to simply assemble our proven combinations, right at home.

IMO,your really better off getting the whole kit (cylinder boring,piston kit,headwork & cams),from the same place.find a builder that you feel comfortable with & is willing to taylor your build to what your looking for instead of what they think you want
