Army Of Darkness won the 2020 WERA/N2 National Endurance Championship on a 2020 Yamaha YZF R1. They then went on to win the 2021 and 2022 championships as well.
Eventually the 2020 engine started jumping out of gear which is going to require a complete tear down to build a new engine for the 2023 season.
Mike Godin at KWS Motorsports offered to be the engine expert so follow along we see how the valves, seats, pistons, rings, bearings and clutch look after 4,000 miles at redline.
00:57 Clutch Plates
01:34 Metal tailings in oil pan
03:33 Worn transmission dogs! (the cause of our problems!)
05:06 Crossplane Crankshaft explained
08:45 Shiftshaft mechanism
10:57 Discussion of engine building philosophy with AOD slideshow
18:06 Chris Peris and Ben Walters lap Barber on AOD bikes
Part 3 takes a deep dive into the bottom end to examine the bearings, clutch, crankshaft, cylinders and transmission gears.
There is also some fun photos of the team and a nice lap of Barber Motorsports Park by Chris Peris and Ben Walters at the end of the video.

in 2022 AOD was sponsored by: Army of Darkness, Pirelli, Yamaha Champions Riding School, Yamaha, Industry13, Chicken Hawk, Wood Craft, Hindle, Supersprox, Thermosman, N2, WERA, Roadracing World.

Pretty awesome series, I learned a lot. I race a 20k mile r1 and the motor still pulls hard. 18k of those miles were on the street. I had the valves checked at 18k but I’m sure I’m coming up on a rebuild.
a new shift selector would be a good idea too!
Great video. I learned some things.
Hey! Engine building is something of a dying art so we're glad you are interested in it!
Need you guy to overall one of this crossplan engine in Jamaica
Great video looking forward to more R1 content.
Great video.
Very informative and interesting.
Curious as to your take on engine break in on a dyno; whether it affects the engine’s longevity?
Thanks!!
In the experience of this race team...RACE engines tend to fail catastrophically from a valve, or gear, or cam chain tensioner or a piston or some other hard part failing. Race engines don't usually wear out from piston wear or main bearing scoring. So, from our perspective, racetrack break in or dyno break in hasn't materially increased or decreased the service life of one of our engines. That said, it won't hurt to break it in on a dyno, we just don't always have one available.
Rebuilding my 14b gearbox currently as cant change from 3rd to 4th under load, most likely bent shift fork. To be fair, 6 years of hard hard street riding, almost always on the upper end of the rpm, surprised it lasted this long and its such a small failure.
But i have a question for you guys.. since i have engine apart again (2nd engine rebuild first time blew bottom bearings). I have a complete spare engine as i bought another engine when i blew the bearings.. so i have the time right now for some "correcting".
Do you guys have any suggestions on what i should be on the lookout to improve and or modify? I don't want race performance, but i do want a little more oomph out of her, so im thinking already to send head off to be cut and ground for better airflow.
I don't want to buy cams or such, but just looking to get a bit more power whilst the engine is apart?
Hi sir I have one of the R1 crossplane but the engine jam up hi think hi need a crankshaft and bearings
Hey guys I am interested in any ideas or services you may have we have a lightning sprint car with a 2017 r1 we are in need of some more lower end torque we run methanol we are also experiencing 3/4 throttle lull where it spits and sputters
Thank you.
Where do you guys order you engine parts from ??????
Ron Ayers or Partszilla usually.
