Not sure what ya mean by rigid 8 wheeler.Those 3x1 configurations are much better turning than the 2x2 with the heavy duty front axles on trucks , overloading the front isn’t too much of a problem
Over here most are rated at 9.5 - 10 tons
What’s your max weight for rigid 8 wheelers
Wish i had a picture of the steel coil I dropped on my 3 axle lead one day. The shop said my pup was gonna be off the Rd for a day but the office had a couple he run for me, then afterwards they sent me to the Ford rouge plant(near Detroit), the guy said how big of a coil you want, knowing I couldn't her two for 75k or so I said the biggest single you can fit on here, he radioed the crane guy and I saw this huge coil coming thru the air towards me , it was what they call a super coil, it was 72" long and I couldn't walk around it on my trailer with the sides on, I also had to leave two of the bows that held the tarp up off, the coil lifted my tarp about 6" higher than the rest of it lol.Not sure what ya mean by rigid 8 wheeler.
Without my over weight permit my trucks only legal for 57,000lbs. with permit 71,250. Depends on wheelbase, most a truck like mine can go is 72500 or 73500 but it's got to be longer than me
Great engine....a little blast from the past!!!The TRX, is a great platform, lots of engine support! 363 Esr cylinder can be made to make it mid 60s for horsepower and right around 50 foot pounds, And be all day rideable some guys are getting into the 70s with a little peeky power curve on gas the the 350 cylinder is cheap!

That some impressive numbers, my banshee at 443cc makes 112hp and 62 foot pounds at 9500 on methanol to the wheels, I don’t know what the at crank numbers would be. 90hp out of a 500 single is a hard to do! The linger cylinder for the cr500 is a basically drag race cylinder, 550cc that can achieve mid 90hp on methanol, but it takes porting a 50-54mm lectron, custom ignition and pipe. Have seen a lot of kart 125, clam 50hp and kart 250 single clam to make 70hp, not a lot of evidence. Torque is were it’s at, a 125 at 70 hp at 20000rpm would only have 19 foot pounds, the 85 cr500 made roughly 50hp and 50 lbs of torque at 5250 stock. I would love to see what they did to the husky 500!Great engine....a little blast from the past!!!
Single cylinder 2 strokes still have a bright future. I've been following a 125cc Czech made kart engine for the last few years.
I think of it as a formula 1 race car engine.
It's been reported European builders are getting 70 PS/HP at 20,000rpm out of the little 125cc single cylinder. They claim it has a capability of running 30,000rpm.
And not to stop there they built a twin out of the same engine putting out 140 hp at 250cc.

Last pictures is my little liquid 1982 YZ125 I built 35 years ago. Being right hand ignition I had no choice to run left hand drive with the chain turning backwards. Idea I got from former world hotsaw champ Gary Walrath out of West Linn, Oregon with his Yamaha 292 Thunder Jet snowmobile engine.
I field tested the Oregon 72LG chain, PowerMatch bars, and radial port sprockets for Gary when I was a faller in the late 1970's early '80s.
I saw him cut at Estacada in 1984 and spent a few days with his family.
I just bought a bi-directional Penton/PVL ignition for my YZ 125 from Dan Gray out of Maryland, Two years ago Dan bought out Penton Racing (founder of KTM MX motorcycles).
If I could have bought this PVL ignition 35 years ago it would have saved me alot of headaches from handling it back chaining and then running it awkwardly for years when I converted it to left hand drive.
So I'm presently converting it back to its original profile and reversing its crank rotation.
With a redesign it will go from the present 40 lb PHO to 30 lbs fully fueled with b/c included.

You can see the cooling lines and electronics cable under his chaps on his left leg, the cart with Oregon decal is beside him.
