Wow. FuelMoto 107!!
I finally had the opportunity to get out and really take a ride on my recent 107 winter build. It is a FuelMoto 107 "kit" with 10.25 slugs and FM B heads. I had done the Wood's TW-555 cams last fall.
All I can say is I can't wait to tune this thing. It really rips. I'm still being nice to it for a hundred miles or so but twisting that throttle is REALLY fun.
Thanks to FuelMoto and wurk_truk for helping to diagnose crossed O2 sensors. That really gave me some heartburn. Fyi. My scoot has grey connector in back and black in front and I had the back grey connector to the rear cylinder. NFG. Rear cylinder O2 sensor is black connector. Period.
Anyway just thought I'd thank those guys and make y'all a bit jealous.... I'm thinking a trip to a dyno is in order to get the most out of this. I'll post a sheet when I do.

Not sure what 12hdrk did, but for mine, Primary chain no, belt drive no, clutch - went to the heavier Barnett clutch spring. I wasn't getting any slipping using the stock spring, but didn't want to take the chance.

No modifications to the drivetrain yet, but I think ill need a heavier clutch spring just feeling the torque that is here now.
I used my stock 103 jugs and had FM bore them. I don't think there will be any issue there. That said, if I had unlimited funds I would have gone with th IC cylinders. There's always the 117 to look forward to.

These bikes don't need much in the way of drivetrain upgrades other than a clutch.
If you are abusive and want to do burnouts and wheelies, then a billet clutch basket and chain drive conversion are advisable. Here's what happens with a Primo Rivera Pro Clutch, a 124" and an abusive rider with a stock basket. It does have a chain conversion. After we replaced the clutch assembly, nothing else has failed, even with countless hole-shots, burnouts and wheelies:
