ATC 110 joined the family

Glad to hear a quick easy fix. No clue how familiar you are with those things but simple and VERY important, if you think it's turning over don't put your foot down to catch it.

The advice I that i gave to my son, not that he'sl listening, is: If it's flipping, scout out a decent landing spot, eject yourself with a certain panache and then tuck and roll. If you dab a foot there goes the fibula, achilles, or both. Thankfully he's got big getoff experience on mountain bikes so I think he'll be fine. I think.

I think 86 or 87 was the last year. I had an 86 250r back in the late 90s. It was an awesome machine.

They sure were awesome! We had massive fun on those. People just couldn't learn to steer with the throttle.

Absolutely. My last ride on a 250r was about 8-10 years after I sold mine. My brother bought (another) one. The field near his house had a couple of inches of fresh snow that morning. I was aggressively ripping around in 6th gear, wheels spinning, and just steering by shifting my weigh, leaning way in, and throttle.
my brother said I was shooting out 10 foot rooster tails and he told his stepson "that's how you ride a three wheeler"

it was an absolute probably last blast on one.

Nothing says you might not get another!

Remember them Yamaha Banshee's? 350 two stroke 4-Wheeler.
Kid in the neighborhood bought one...
My friend Paul was just ripping it across a field. Sliding the tail back and forth.
Well, it grabbed and he high sided it big time. The machine barreled rolled about four times!
It was all tweaked, busted up body work. Paul had to buy the kid all the parts to make it right again.
However it was never right. We think the frame was bent... The kid didn't know any different as long as it looked fixed.

Banshee... unforgettable machine with one of the most epic exhaust notes of any quad. Excepting the GS 1100 swapped Quadracer that used to roam the sandpit where we rode.

My nephew continues to impress me. He's a junior or senior in HS and over the last few years has been buying / repairing / horsetrading / flipping units.

He made a deal on a Banshee that he rebuilt and also has an ATC 250r in the (parents) garage. He is fully aware of the significance both.

Those old 250 and 350 2 stroke 3 wheelers and 4 wheelers never made no sense to me even in my younger yrs. Nobody never needed to go 70 plus MPH in the woods nor in a cow pasture... Those things were, and are, dangerous.

So is life. Those beasts were epic. We did most of our riding on them out in the middle of the desert in AZ and at the dunes in Glamis.

I might tend to agree but... I had a ball on mine. I'd think that back in the day once one graduated to one of those that'd they have a bit of skillset built up. From what I recall is that the beginners that treated them as toys are the ones that got hurt. All ancient history now...

The Banshees were awe-inspiring. I ended up with a full race Banshee motor in one of my RZ350s after I blew up the stocker.

You young hooligans! The measly 110 is idling fine but at its loping idle it is making concerning noises, either cam chain slap, or more dramatically, rod knock. Son doesn't care, he will ride it till it explodes. But I like things right. so I'll be using my stethoscope on it, checking the cam chain, etc. I kinda sorta want to rebuild the engine just because. Heck I did a ground-up on a Norton and it runs fantastic.

[oldGSfan]

I adjusted the valves, It was a wet noodle at the pull cord to both the intake and exhaust being zero clearance. I set them to .003 and it is way better, there's now the normal resistance on the pull and it has a good deal more power. But there is looseness in the engine, when idling very slow you can hear the knocking, When running it isn't as obvious, but the pipe is sorta loud, so...

I am wondering if it is rod bearings. No big deal if it needs a rebuild, I would be happy to set it right and teach my son some wrenching. I don't want it to tear itself apart. Doing some research. A couple of short videos.

Edit: I don't know why there's no preview on these, I added like usual with ...... tags. Maybe YouTube is to blame, I only just put them up.

Yeah, can hear it clonking as you shut it off.

[oldGSfan]

Well, there was a lot of clattering from the pipe so I had a closer look (i.e. a look) and saw stripped threads, one bolt hole had a huge sheet metal screw angled in sideways and the other was galled. It had no exhaust gasket. I removed the DG pipe and de-rusted it, then painted it with VHT ceramic black. I was able to get an insert into the badly damaged wood screw damaged threads and fix the other hole with a homemade chaser. I got a stud kit and washer for $5, and on the insert side, I stuffed the hole full of JB weld, jammed in the stud, and tightened it up. It's solid. It would be best to replace the top end, but it'll do as is for some time.

Then I set the point gap and timing, which was far too advanced. That was causing a good deal of the racket. It is much quieter with the two things done. But just as I got it running the petcock broke on the Chinese carb. Gonna get a $6 replacement but look for a genuine Keihin to rebuild.

The thing is so basic. In '80 or '81 Honda went to CDI and had a porthole to set the timing with a strobe. This one has none, and if you take the recoil starter off to get to the flywheel to time it, you need to figure out how to start it. So I timed it with the light bulb method.

Oh, I also fixed the slow leak in the front tire, it was just a valve stem. Had to get creative to break the bead.

[oldGSfan]

OK probably last post on this... but wow, got a bunch of little stuff done and it runs pretty decent now. The 'smoke' was just it running rich. The clunk was mainly the timing being way too advanced. Adjusted valves, points, timing, carb, chain, brakes, changed oil, new NGK plug, exhaust studs (above), fixed split leaking front tire valve, and it's ready for Baja!
