Only 7,000 Miles After 20 Months of Ownership

I was honestly hoping I'd have put 30,000 or more miles on this thing by now. 7,000 in 20 months is pretty sad. @#$% thing won't stop breaking. It's endless.

The only other vehicle I've ever owned that was this unreliable was a 1979 Ford Courier pickup truck.

On the bright side, the monthly payments will end in December (private seller). It will be good to at least be out from under that.

I'm not here to whine or to toot my own horn. Not sure if I ever come across that way. I just hope other V8 bike/trike owners out there can glean something useful from all my rattling on. I post a bunch, but that's only because I'm learning a bunch. I've never owned a "ride" of any kind before, only "cages." Irritating and mighty fun experience all rolled up into one. Well worth it. I hope some of you out there are learning from my experiences. I don't mind being the Guinea Pig, as long as it helps someone else.

On the Road Again

Throttle cable is replaced. Feels a lot different than before (it has some idle slack in it now; it didn't before), but every bit as responsive. It just takes a little bit of an extra twist. I'm gonna have to re-learn it to an extent, but at least now I can get back to putting miles behind me.

TH350 Transmission to Differential Coupler

Here are photo's of the coupler between the rear differential housing and the TH350 transmission.

I had been entertaining the idea of eventually swapping the TH350 for a 700R4 so I could have an overdrive gear for the freeway, but considering a 700R4 is about 4 inches longer, this is obviously not going to happen, not without a great deal of expense, anyway.

Body Tilt Hinges

Here are old and new pic's of my body tilt hinges. The first two are from when they cracked in half from age and fatigue about a year ago. It happened to the hinges on the left and right sides of the trike. They were welded back together with an additional piece of steel as reinforcement. The hollow metal roll pins were replaced with solid clevis pins. The bolts that hold them to the body kept working their way out even with split lock washers, so I installed nylon lock washers on the back sides instead.

On the Home Stretch

Now that I have replaced and/or repaired nearly every external working component, averaging one breakdown for every two to four weeks of road time, putting the Hoss out of commission for anywhere from one week to three months per breakdown, I am finally rounding the "home stretch." This thing will be paid off in December. If I encounter another breakdown before then, I might have to consider throwing in the towel and seeking owner #9. For now, all is well. Come on baby, only three more months! Make daddy proud!

New Problem: Hanging High Idle

The idle sticks at around 1,500 RPM now instead of settling down at 800 like it's supposed to. I have a separate thread opened in the technical forum. I'll post an update here after it is resolved. I will also post the resolution on the technical thread. I just hope it's a quick fix.

Otherwise, I've pretty much decided I will sell this thing. Regardless of all the effort and the cash I've sunk into it, it just still gives me way too many problems. One ride-stopping repair every 500 to 2,000 miles is for the birds.

Hanging High Idle Resolved, Confirmed

Spark plug #7 was loose. It needed at least a turn and a half. I don't know how a steel plug in an aluminum head worked its way that loose, but that's how it was. I re-torqued to 20 ft-lbs. and now all is well. The Hoss idles at 800 RPM as it should, regardless of cold or hot riding, in any traffic.

Not a iron head is it ?

For Future Reference, if I Ever Extend the Frame for a 700R4...

Ideas for extending the trike's frame (2001 Boss Hoss) to make room for mounting a 700R4 overdrive transmission in place of the existing TH350...


Idea #1: figure out a way to extend the internal slugs inside the top-side frame tubes at the splice/separation points, despite the angle of the tubes. The bottom tubes would be easy.

Idea #2 (thank you for the suggestion, Paul H): drill one hole in each of the former swing arm mounting plates. The holes' centers should be located precisely 1-3/4" from the centers of, and behind, the existing bolt holes (3/4" dia). Next, fabricate a plate for relocating the bolts on the top side of the rear frame, to make up for the offset on the swing arm plates.

Will post photo's of the areas in question as soon as my camera charges up.

Hoping I'll have a fuel saving 4 speed installed by this time next year.


The first four photo's are of the forward frame separation points (factory Boss Hoss frame splices). The last eight photo's are of the rear frame separation points (former swing arm and shock locations).

Hole in Radiator

Two or three weeks ago something bounced up off the road and got tossed by the engine pulley. It tore a gash in the backside of the radiator and caused at least one leak. I'm gonna have to pull the radiator off and see if it can be repaired.

Radiator Fixed

The holes have been repaired and the radiator re-installed. Re-installation was nowhere near the booger I expected, especially since now I know the trick to those crazy Spectra Racing Magna Kool hose sleeves. No-brainer for near anyone else I'm sure, but I over-think EVERYTHING and turn "space cadet" too easily. Anyhow, it's sealed up great, the coolant flows as it should, and the operating temperatures are within the expected range. All's well! ...Until NEXT time... :trike.jpg:

CPP Classics JK613B 45PSI Rear Brake Light Pressure Switch

I've installed a CPP Classics JK613B low pressure 45 PSI rear Brake Light Pressure Switch to replace the 90 PSI NAPA unit I normally run. Those things never seem to last more than a year, if that long. I figured the line pressure from a non-vacuum assisted 5/8" bore master cylinder (foot brake, drums, automotive setup on a trike) might be the culprit.

I have been informed by a member here in another thread, that the automotive switches can be sensitive to DOT5 fluid, as they are intended for DOT3. I'll keep an eye on things and will update this thread at a later date if I have to swap to a Harley-Davidson pressure switch.

Mud Flaps and Anti-Slip Strips Installed

I tilted the body and bolted mud flaps to the bottom rear of the rear storage bin tonight. Took a few hours because the space was cramped and a pain to measure and drill. At least now I won't sandblast people behind me when we ride staggered.

I also added some self-adhesive anti-slip strips to the chrome plates on the body, where the rear passenger rests her feet. I put a few on the rear seat too, to help keep her bum planted in the turns.

I'll post pic's some other time. Too tired for it right now. My back's breaking from being hunched over all night.

Recent Electrical Scare

A week or so ago I thought the Hoss had burned up another continuous duty solenoid. I have had to replace one about every 9 months to a year, it seems.

The Hoss had begun displaying symptoms that were common the each time the previous solenoids had burned out:
- Instrument cluster, lights, transmission cooler fan, and fuel pump had come on as usual when ignition key was turned
- Handlebar button turned to "Run" position
- Throttle twisted a few times to get fuel into the carburetor
- Start button depressed; Engine starts to "roll over"
- Everything suddenly shuts down/goes dark; No power, nothing
- Repeat with same results
- Third try, no response at all
- A few hours later, the whole cycle is repeated as if nothing had happened; All seemed well until the start button was depressed again
- Everything went dark again, but stayed dark this time

In summary: intermittent power

A hand-held voltmeter revealed 3 volts between the battery terminals, and also 3 volts along the ignition path, dropping to 0 volts when the key was turned. An inspection of the wires revealed the positive (+) battery terminal had vibrated loose at some point. I recharged the battery overnight, and now all is well. Glad I have a $200 Optimo Red in there!

Lesson learned: include battery cables in the routine "pre-flight" inspection. I'm glad I didn't spend big bucks on any parts, except for a spare continuous duty solenoid that I'm sure I will eventually need anyway.

Irritating Little Repairs: A Way of Life...

Slung another alternator belt on the freeway yesterday. Impossible to keep this pig happy. At least it lasted a handful of months longer than the rest.

Good ole spark plug #7 worked its way loose again and tried to kill me by stalling in 3 lanes of moderate traffic. Took about a half hour to figure out what was wrong, after I had drifted to the center turn lane and had received a police vehicle blockade. Glad I discovered it.

Less serious issue is coolant leaking from the top-side engine mount studs...AGAIN...

Ole girl specializes in shaking herself apart. I can see the top engine mounts, alternator belt, and good ole park plug #7 are going to be endless pains in me caboose...
