I’d be interested in seeing that conversion. Old style rotary sleeve valves were driven from below. Rotary valves embedded in the head have generally had short service lives, which is why they don’t appear in general automotive use.
Gander Outdoors, the new sponsor of the NASCAR Gander Outdoors Truck Series and a subsidiary of Camping World Holdings, Inc., recently expanded its national footprint with the opening of 13 Gander RV dealerships with additional dealerships planned for the remainder of the year.

I’m not sure a piston / valve crash with a camless would be as bad as a cammed engine. With a cammed setup, you have two metal objects smacking into each other, with nowhere else to go. On a camless, the piston would hit the valve and be pressing against the force of the actuator. I’m not saying that no damage would be done, but it might not be as bad as the bent stems and cracked crowns we’re used to seeing. All this said – a properly designed camless setup would fail safe – so no damage could be done.
Electrocution hazards make it unwise to use corded masonry cutoff saws whenever water is present, but gasoline models come with their own shortcomings—exhaust emissions, weight, noise and engine maintenance to mention a few.

Despite a 27.00 ERA in three appearances this spring, Boone believes reliever Danny Farquhar is closer to regaining his big-league form than the numbers indicate.
This new MacBook Air was shown to roll with a TouchID home button, and an Apple T2 security chip. This T2 chip brings “the most secure boot process of any notebook” said Apple’s Laura Lagrove. This system brings the secure enclave, unique per-chip ID, user and filesystem keys, and secure boot.
I’d love to lay my hands on 8 or 16 of the freevalve units, controlling them would be another matter but imagine the likes of a megasquirt3 or similar with a valve timing mapping table being adjusted in real time to demands, boost level, fuel injection quantities etc. I’d just make a new head from raw stock to use them to fit my existing (drag) race bike with no limitations around how many valves or their placement for maximum casting strength but still line up with the lobes of the cam. Dyno setup might be fun mind. But bring it on. If I ever finish converting my water brake to closed loop in the meantime

And if you are really ambitious you can engineer one that can launch a projectile at or above the speed of sound.
While the chassis remains the same, the suspenders it wears went for a trip to the future and gained Kawasaki Electronically Controlled Suspension (KECS) technology. Now, based on the riderâs selection of four modes (Sport, Road, Rain, and Rider mode (Manual)), the KECS automatically adjusts to the road surface in real time. This means that, every 10 milliseconds, the KECS ECU is receiving information from suspension sensors, the IMU, and the ECU about the status of the motorcycle and making changes to the solenoid-activated suspension damping. All of this should increase rider confidence over a variety of road conditions.
Braking is handled by a pair of 300mm discs up front. The calipers are radial-mount, 4-piston KTM-branded units manufactured by J.Juan, and weâve already noted the Cornering ABS. Out back a single 240mm disc and a single-piston caliper handle stopping chores.
