This week's screwing around projects.

Got the manual steering conversion done on the Rambler project.  New view is up on the Because Rabbler youtube channel.  Today I was able to get it out of the garage (first dry day in the 60s, and probably the last for the rest of the month) and sent it off to a buddy's house to get the 12 point cage installed.  This is literally the first time the car has been out of the shop in 6 months.  Super dusty, but a 10 mile trip strapped to the car hauler took care of that.



a couple weeks ago I brought home a 1987 Honda TX250X rolling (barely) chassis.  It was basically given to me because I was willing to haul it away.  :)  No plastics, no engine, rear bearing carrier was, for all intents and purposes, destroyed.  It came with a new carrier, but it didn't fit this bike... no idea what it actually goes to.



Fast forward a week of cutting and welding, to this...  Basically a no-purpose woods "gator-esque" woods antagonist.  Still VERY MUCH a work in progress... but it's got a new carrier, a six-foot wheel base, double wide seat with steering on the left (via an actual steering wheel), and it's likely going to get a mid-engine (under the seat) power plant from a 1977 KZ650 that followed me home last weekend (you can see that ugly bastard in the background).




It's getting a payload bed on the back with twin 12v linear actuators, a full floor, possibly a small winch, and like I said... about 65 horsepower through a 5 speed gear box ;)  Still a LOT to do of course... gussets, brakes, roll bar, sheet metal, fender struts in front, fenders and a bed in back, wiring, new tires, shock rebuilds/replacements, the "dash" is just sitting there waiting for final location (thus the mile long legs sticking down), and so on.  The quick release steering hub actually came in the mail shortly after I took the pic.  Now I can do a final location on the dash, drill the steering u-joints and shafts for bolts to lock them down, and get the steering wheel bolted in place.

But by the time the weather sorts itself out here, It should be ready for some tire shredding. :D

I had a 250X FourTrax, it was a blast to ride. I had trouble keeping up with my buddies, though, who had Banshees, an LT500 or any one of a dozen 2-stroke motocross bikes.

I sold the X and bought an old beater TRX250R, Honda's 2-stroke "race" quad. Fully rebuilt it- I mean from the crank, up- and made it a screamer.... right about the time my group of riding buddies was breaking up. (Getting better jobs, moving out of town, getting married, having kids, etc.)

I kept riding it for a year or so after that, but it's no fun blasting trails alone- and at the time, all the other riders were switching to motocross-only, as the local race track had just added an MX track to the complex. (Bikes only, no quads- it was ten, fifteen years later before they added a quad class.)

Still have a soft spot in my head heart for nice, fast 4-wheelers... Every now and then I'll run across somebody selling an old 250EX that needs work, or one time, I had a chance to get a "project" LT500- which I've always wanted- but the last thing I need these days is another personal project. 😁

On your Rabbler, I note an interference issue with your front tires. Looks like you're going to have to play with your wheel offsets some. 😋

It's not as bad as it looks. They don't rub, but it's VERY close.  Which means any suspension compression may get bad. I'm probably going to the bring front up an inch though.  The corvette front suspension is pretty wide to the axle flanges.  Part of why I'm using the steel wheels is they offered the least backspacing.  They are 28" tall too, which doesn't help.  A buddy keeps trying to get me to go 26" but I think that would look to small in those oddly large wheel openings.
Honestly, the back tires are MUCH closer to interference fit than the fronts.

Well, if you want to outrun / outgun the other guys at the track, there's always this WRX-powered AWD ATV..

-Not to hijack TW's thread too much further, but back while I was into the quads, I was- unsurprisingly- very interested in custom quads.

Back when we had such things and magazine racks, and people still read magazines, I religiously read the two 4-wheeler issues every month. Dirt Wheels and what was at the time called 3 & 4-Wheel Action (even though by that point the 3-wheelers had long since gone obsolete.)

And my favorite articles were either the (unfortunately few) do-it-yourself bits, or articles on custom rides. And of the latter, my favorites there were generally the heavily-modified stuff generally specifically used for sand-dune riding at Glamis in California.

Guys that had taken the aforementioned Honda 250R (which had a version of Honda's CR250 motocross bike 2-stroke, except with a counterbalancer and a forward-stroke kickstarter) and dropped in an engine out of a CR500. Or took a Banshee frame and split it to make room for a Kawasaki KZ1000 4-cylinder. Or an older Kawasaki H1 2-stroke triple.

There was one guy, regularly featured, who they called Mad Dog- Mad Dog Graham, or something like that. He was always building wild tube-framed freak quads using things like CBR600 engines- and then turbocharging it- or a CBR900RR engine, or whatever. I remember looking him up a few years ago after I'd rediscovered my pile of 4-wheeler magazines, and was surprised to see I couldn't find hide nor hair of him online. No mention of the bikes, no personal page, no mention of him, etc.

But yeah, I loved the custom quads. Mostly stock 250Rs that had been all polished and chromed, the one full-custom quad some famous-at-the-time shop made that supposedly only weighed 230 pounds, complete and fueled... (Had some older air-cooled 2-cylinder twin, where they'd turned the cylinders around so the exhaust pointed straight out the back, the whole thing was on a minimalist custom chrome-moly frame, and run on alcohol. Built specifically for hill-climbing competitions.)

It was reading things like that, and the desire to build my own (among other factors 😁 ) that eventually drove me to get my own machine tools and thus, indirectly, led me to where I am now. 😋

Found a mention of 'Paul Graham', involved in drag racing on sand in California, with home-brew stuff, and everything from quad bikes to 7000HP top fuellers... Some of them might qualify for mad dog-ness...
