Yamaha RD350 Part 6: Rubber Match

One day many years ago, when I was around 12 or 13 years old, I took my metallic blue Honda Mini Trail on the road. My older buddy, Russ Adamson, who was legal on a Honda CL100, was with me on the street adventure. My Mini Trail didn’t have a tag, I didn’t have a license or any business on the pavement, but that didn’t stop us. I just wanted to ride, to be free without being hassled by The Man, like Peter Fonda said in those biker movies from the late 60s/early 70s era. Unfortunately, The Man had other ideas. I made it all the way to Milam Dairy road in the town of Medley, about 10 miles from home, when I was pulled over for obvious reasons.

The cop was a real stickler for details. He arrested me and called a tow truck to haul away the mini bike. I sat in the back of the patrol car looking out the window as he took me to the cop shop. Russ checked out ok so he was allowed to ride back home. At the cop shop the other cops looked at my cop like he was crazy. “You’re arresting him?” My guy held firm to his principals. I was booked, finger printed and was going to be put in a jail cell when one of the cops said, “You can’t put him in a cell, just let him sit here behind my desk.” I didn’t know exactly where I was, South Miami I think. We had driven a long way to the station. I called my house but nobody was home so I sat there wondering what prison food would taste like.

The situation was so unusual I didn’t know I should be scared. Other cops were stopping by and talking with me, trying to keep me in good spirits. I had quite a few spectators. I was a real celebrity collar. Some cops would just look at me and shake their heads in disbelief. One of the cops told me, “We’ll see you back here in a few years on a big Harley,” and then laughed at his joke.

Russ had gone to my house and told my mother what happened but he wasn’t sure who arrested me. Miami in the area I was pinched had several overlapping police departments. There is Metro Dade, Medley Police, Sheriffs and a few others. My mom started calling the various forces patrolling the city.

“Your mother is coming down to get you,” the desk cop told me. Mom came in the police station as angry as I ever saw her. I figured I was done for: no more mini bike. Astonishingly she was not angry with me. She read the riot act to any and all cops within earshot. Turns out I was like 30 miles from home. In lieu of bail, Mom had to show her voter’s ID card to spring me and all the way home she was mad as hell. But not with me.

Events were getting out of hand. My mother called Charles Whitehead, a writer for the local Miami paper and he wrote a humorous column titled, Dangerous Joe Rides Again.  In it he joked about the police arresting and fingerprinting a little kid. Whitehead claimed that a desperate crime spree was stopped by the brave actions of the police. Remember, this was before kids routinely shot up schoolyards. I think Whitehead was pining for a gauzy, Norman Rockwell, soda fountain type of police encounter. The upshot was Whitehead felt the cop should have tossed the mini bike in the trunk of his patrol car and taken me home. Which would have been worse for me by far. By arresting me the cop took all the attention away from my stupid actions and took it on himself.

With my mom and dad by my side I had my day in traffic court. After a long day of waiting we were the very last case on the docket. I was charged with driving without a license and having an unregistered vehicle on the highway. Neither of which you normally get arrested for. Since I had no license I couldn’t lose it or get points against it. I plead no contest. I don’t remember the fine but it was like $100 I think. That was a lot of money. I never did manage to pay them back.

This old story came to mind when I rode the untagged RD350 down to the La Luz post office to sign for a package of new rubber carb tops from India. India makes a lot of parts for RD350’s. I haven’t switched over the title so the RD is still in the previous owner’s name. I haven’t registered it for a tag because I’m still working on it and to get a tag you have to buy insurance. The title was safely at home so I had no proof the bike was even mine. It was as if I hadn’t learned a thing from that arrest so long ago.

Like that Honda Mini Trail, the urge to ride the RD350 defies common sense. I think that’s the appeal of vintage motorcycles: they make you feel like a kid again. I just want to be free, to go where I want without being hassled by The Man, you know? The bike still needs a lot of work but I think I’ll focus on getting it legal next. It’s obvious I lack the willpower to stay off the thing. Dangerous Joe indeed.

Upon Further Reflection: 2020 Go-Bowen Fit Right DB003 40cc Mini Bike

When I first opened the packing on the Go-Bowen mini bike I was impressed by the quality look of the little green monster. That first impression has taken a bit of a hit as I ran into quality control issues with the Go-Bowen mostly relating to the back wheel. (So far, that is.)

The little mini came from the factory with the chain adjusted ridiculously tight. The mini would hardly roll. I loosened axle and took a few turns off the nicely made chain adjusters and all seemed well. I drained the factory engine oil and replaced it with a high grade of store brand stuff and dumped a few ounces of fuel into the gas tank.

Starting the mini was very easy. There is a primer bulb under the carburetor and a few semi-erotic squeezes later I could see the fuel flow into the clear gas lines. A bit of choke, a few easy pulls and the mini was running like it was made to run. For only 1.4 horsepower the mini has a get-go feeling. The idle was set high so I took a few turns off the idle screw. I took a hot lap of Tinfiny’s upper reaches when the chain flew off.

This was odd because I didn’t loosen the thing all that much. I pushed it back to the shop and had a look see. Turns out the axle adjusting slots are not indexed the same and to center the rear wheel in the frame you end up with the axle cocked in the adjusters.

Once I had the chain running true I noticed the rear brake caliper wiggling alarmingly. A severely wobbling disc rotor caused that problem. The thing is like 3/16” out of true. It looks as if the flange is machined wrong or the disc itself is bent. I haven’t gone any further into the disc problem yet.

The mini rides fine once you get the chain to stay on and if the thing had any more power you’d probably flip over backwards. There is a heck of a lot of noise coming from the primary chain housing so I’ll have to look inside to see what gives.

The exhaust pipe on the Go-Bowen exits directly on the rear brake cable. I will need to rig some sort of turn out to redirect the hot gasses but for now I slipped a short piece of silicone heat shielding over the cable for protection.

It was a disappointing first run with the Go-Bowen. I will work on the disc and the noisy primary situation when I get time. Even with the issues the mini still seems like it’s worth the $299 with shipping included but you’ll need to budget a few hours going over the set up fixing shoddy assembly from the factory before any long distance travel is attempted. It’s like they built a nice mini bike then had their stupidest employees assemble the thing. More will be forthcoming after repairs when I get a chance to road test the mini in true ExhaustNotes.us fashion.

Hasty Conclusions: 2020 Go-Bowen Fit Right DB003 40cc Mini Bike

I keep hearing a complaints about Globalism. People are talking. Some folks don’t like the idea of making the world’s population one homogenous group of consumer/aphids to be milked by evil corporations. I get that and it bothers me that a mini bike that cost $250 dollars in 1970 now costs only $44 adjusted for dollar devaluation. That’s right, this Fit Right Chinese-built mini bike costs less in real dollars than a really long, long-distance telephone call did in 1970.

In some ways that old 1970 mini bike was better. It had a couple more horses than the DB003’s 1 horsepower. It was made in the USA, which helped support local businesses. I think the fit and finish on the Fit Right DB003 is at least as good or better than an average vintage mini, maybe not as good as a Rupp but then nothing was as good as a Rupp. As far as reliability goes, those flathead, loop framed, scrub-braked minis were not a vehicle you could ever assume you’d get back home on. Time will tell if the Fit Right holds up.

I’m in the middle of a back porch remodel so I only have time to do a short review on what I’ve found unboxing the Fit Right. A more thorough road test and video will be forthcoming.

The Fit Right DB003 comes fairly well packed in bubble wrap and then molded Styrofoam all stuffed inside a heavy cardboard box. The cardboard is thick and strong, it’s too good to throw away. I’ll be using it for a working pad to cover the dirt and ants while tinkering under the MBG-GT. Even though the mini was packaged well a ragged hole was punched into the side and parts were rattling around.

Once out of the packaging the Fit Right mini comes fully assembled except for the handlebars. It only took a few minutes to install the bars after a few hours searching for a 10mm socket. The bars are held on by four bolts/nuts and one of the nuts had gone missing. It probably fell out of the hole. Luckily I had a spare 8mm locknut left over from a roof rack installation.

The fit and finish on this $299 (shipping included!) Fit Right mini bike are pretty good. The graphics on the plastic gas tank cover are molded in so you won’t have any cheap, stick-on labels peeling off. The real gas tank under the plastic is made of steel. One odd thing is that there are no steering stops: the forks bang into the gas tank at full lock. This mini bike is smaller than usual; I’ll need to rig some bar-risers to clear my knees.

The Fit Right Model 139F, 40cc, overhead valve engine is jewel-like. Its castings look smooth and there is no rough mold flashing at the edges. The frame is fairly complex design with a lot of tubes and angles that don’t seem to make any sense. I suspect the stylists threw a couple extra pipes in the mix to make the mini look cool. Welds are pretty good, much better than I can do. The Fit Right even has folding foot pegs, a rare feature on the old mini bikes.

Unusual for such an economy mini motorcycle the Fit Right came with a flimsy but usable tool kit, something lacking on a $40,000 Harley-Davidson. For $299 you can’t expect Japanese-level quality, however I’m satisfied with the DB003’s presentation and the easy assumption of owner-provided care.

There are some interesting things on this bike that I need to look into later. For instance the fuel tank has a return line and a feed line but no fuel shut off. The engine has a fuel pump because in stationary-engine uses the fuel tank mounts below the carburetor. The carb itself is odd looking. It may be a diaphragm type carb like on a chain saw. The drive train is double reduction and I’ve just got to know what is under the nifty cast aluminum primary cover. The rear brake is a mechanical disc, which is a huge improvement over the old-fashioned scrub brake that simply rubbed on the tire. I don’t like that the hot exhaust exits directly onto the brake cable. I need to turn the exhaust tip more downwards.

The Fit Right DB003 is quite a bit more sophisticated than your traditional double-loop mini of days gone by. Whether this added sophistication equates to better performance remains to be seen. As soon as I get time I’ll get the mini running and ExhaustNotes.us will have performance numbers and a riding impression.
