Arash-
If I had something between my legs spinning 16,000rpm I would want good oil in it too!

I would have to drive 150 miles round trip to buy oil from the nearest pilot shop.

I just needed some 30w chain oil for my chain saw but didn’t want to drive across town to get the cheap stuff at Wally World.

Arash-
I just watched a show on Discovery or Science Channel about racing motorcycles, no thanks, I’ll stick with airplanes! Losing a knee on a pebble or wiping out and getting smashed, not my thing.

Good luck, buddy, have fun and drive safe.

Amazing how they come out of a corner pulling a wheelie accelerating. Seems like the rear tire is barely touching the ground.

I've had several motorcycles and still have a '34 Harley but don't regularly ride it. After 3 accidents with stoopid drivers pulling-out/turning while looking me in the eye... didn't cure me.....I defended myself by driving more defensively.
But.... I quit motorcycling permanently after I realized there's not much more I could have done defensively when I hit a deer at 70 mph and lived thru it.

200+ hp? What's the power to weight ratio on those pocket rockets? Now with a 7:1 PSRU that'd make an interesting aircraft engine conversion. ... if you didn't mind a 200 hr. TBO or a 16,000 rpm engine screaming at 150 dB.

And as we often hear about auto engines, they aren’t designed to run at full sleep/rpm most of the time

I used to have a Kawasaki 750 triple cylinder 2 stroke . [H4]. OMG what a machine , couldn’t go past a gas station . Rear tires were changed nearly every time you would gas it up. Incredible drag machine . I wound it out to 140 mph and it got the speed wobbles . I am still shaking writing about it . It didn’t have a fairing . It was at red line one day and passing a semi [large truck with a long trailer] and it seized and I had a pillion passenger too. Back wheel locked and trying to pull the clutch in before the rear tire blew out. Tire blew out as the rear of the trailer passed us by. Managed to stay upright.
Next day engine out for repair and a new rear tire fitted , bike repaired and SOLD. My insanity streak was getting shorter , so I bought a new Lotus Europa S2 . That’s when I met my wife . So back to doing non exciting things , flying a 170A. And still alive . However I do have another story with my son,s Kawasaki 750 ninja. Maybe later . The insanity streak is still there.

I had a Z1 900 Kawasaki back in my wild days. What a rocket! I did the same thing, high speed wobble at 140mph. manage to get it slowed down ok though. Alcohol was involved... sure glad I grew up. Now I'm content to put around on my 2001 Road Glide Classic at the speed limit and just sound good.

Same thing happened to me! In 1970 I bought a new Kawasaki 500 3-cylinder (2-cycle engine). It didn't have any low end torque but once it hit about 3000rpm it would jump out from under you. When I bought it the salesman would not let me test drive it until I paid the full amount, $999.99. When I was getting on it to drive away from the dealer, the salesman pointed at the throttle and very seriously said, “Consider this a trigger”. I knew it would be fast but really didn’t understand until I opened it up the first time! I never got outrun by anything until the Kawasaki 750 3-cylinders came out. The 500 would get the high speed wobbles at 120mph so it must have been a systematic design problem with the Kawasakis, plus the drum brakes would not bring the motorcycle to a stop from above 80mph.

The night I drove thru a stop sign on a busy highway at 80mph without seeing it or reducing throttle was the night I decided to sell it. I missed it but am still alive.

Arash, it's not that I don't like speed, its the thought of wiping out on a motorcycle that keeps me on 4 wheels. So now I have a 53 year old 150mph go kart!

Richard, tell us more about that cart!

Two single lunger 2 strokes (need to get to a full size screen vs my phone)

Drivetrain?

Gears?

A high school buddy of mine's dad bought the kart new in 1966 and my buddy raced it for several years and won several races in his class. It originally had one 70cc McCulloch MC-7 racing engine and two saddle tanks for endurance racing. He raced it until about 1970 then stored it in the garage under a blanket. In about 1982 he bought three new 100cc McCulloch MC-93 racing engines for it but never installed them and left them new in the box. The engines have roller main bearings that turn up somewhere around 20,000rpm and drive a live rear axle with two Airheart hydraulic disk brakes and Airheart hydraulic front drum brakes. It uses a #35 chain drive but don't know the sprocket tooth count.

I got the kart from my buddy in January, 2017. It was in his garage under a blanket and had not been run since he parked it in about 1970. He told me it was built by Richard Peck at P&R Enterprises in Waco, TX so I looked Richard up on the internet and called him. I told him I had one of his original karts from the mid-1960s and asked him if he would like to see it when I drove it home from Dallas to Fredericksburg. When I stopped at his house he asked me if I would leave it with him and let him restore it back to original condition. Richard is in his 70s and hasn't built karts in years but he now restores karts that he built back in the day. I left the kart and two new old stock MC-93 engines with him. Nine months later the kart was completely restored with the two engines mounted with expansion chambers. Richard told me it would go 150mph on paper but it remains to be seen if it will. Richard was having heart and back issues when I picked it up and we didn't get a chance to tune it up and dial it in. He said to bring it back when he was feeling better and we would take it out to the track and get it going. So for the time being it is in my hangar under a blanket waiting on the call.

Notice that common factor amongst 170 owners!! It’s that insanity streak . A few years ago [about 6] my son came home with a new Kawasaki 750 ninja bike. Very light with some fairing . Take it for a ride , as he threw me the keys . So up one of the suburb roads off our street it is about 3.5 miles long with a slight hill at the top , i was getting the feel of the bike , nice balance , brakes progressive ,steering very positive . I turned the bike around on top of the hill no traffic , now let’s see if this is good as the Kawasaki 750 triple . I rip through the gears changing just under red line each time this engine just screamed with a high pitched roar ,just hit top gear [this is F U U U N N ] and then saw my street looming up and the realestate had disappeared real quick . Glanced at the speedo 130mph. OMG brakes were maxed out and it felt the bike was being buried into the road.
Turned into my street expecting blue flashing lights etc . That was done in a 35 mph area center of town . It’s nice to be insane sometimes .

Loved the video, just proves I am still insane. These days my reactions are a little slower and a little too old to have fun like that.

All the new liter sized sportbikes can do 100 mph in 1st gear...and you still have 5 more to go.

So what. The 1928 J-model Duesenberg would do ninety in second-gear and it had five gears also....m/c's have made not much progress, and certainly not any advance in styling, to my thinking... Even the green ones looked good... The ladies liked them also...

Thanks Richard! Neat machine.

I had a little pumpkinseed that would do just under 30 and that felt like much much more when kneeling and low to the water. Can't imagine what that cart would feel like at highway speeds, much less something faster!

Great story too to get it restored by the original builder.
