1970 Honda CT90 Junkyard Dog

It all started like so many bad ideas with an Ebay auction, followed by a six hour car ride the day after the auction ended. I had been sort of casually looking for a Honda CT90 or CT110, not to restore but just to get running and ride it around on the farm and at bike shows. At last years AMCA Southern National swap meet in Denton N.C. I missed 2 of them that were in my price range by just a matter of minutes. In fact when I spotted one of them and started walking towards it another gentleman had who was much closer walked up and handed the seller cash and they were filling out the paperwork by the time I got there. Since I’m always scanning online sales sites, backyards, junkyards, and trash piles for interesting stuff, I knew sooner or later a Honda CT90 or 110 would cross my path for the right dollar amount.

This one popped up on Ebay down in Ladson S.C., it was not running and missing a lot of parts, but I bid what I thought it was worth and was pleasantly surprised when it actually sold for what it was worth and didn’t run up to a stupid price like things do on Ebay sometimes.

I’m going to confess that I staged the rest of these pictures the next day after work, but the surroundings seem to work really well and you really can almost imagine stumbling across something like this abandoned in the woods.

She hasn’t traveled far in 47 years, only 3,353 mile on the odometer.

Honda CT90 missing parts

The muffler and battery box are gone, and the wiring harness is a bit of a mess, but the engine still turns free.

One of the coolest features of the early Honda Trail bikes like the CT90 was the rotating handlebar mounts designed to make them easier to transport on bumper mounted motorcycle carriers. You pulled up on the big lever in the center of the bars and then you could turn the bars sideways for more room.

Another great feature that was introduced in the middle of the 1967 model year was a dual range transmission giving you a total of 8 forward gears. Low range was for serious off road work and the high range was for normal trail and road use. A lot of people swap Lifan engines into them for more power and reliability but my plan is to keep the original engine just so that it will still have the dual range transmission.

That’s it for now, I’m going to check it out further and will keep you informed on the progress as it happens. I also have another antique motorcycle project going that I haven’t shown on this blog yet but it has been all over my Facebook page & Instagram if you want to check those out.

1982 Honda Passport C70 For Sale

1982 Honda Passport C70 For Sale

I have greatly enjoyed this little Passport over the last year and a half that I’ve owned but it is time to let it move on to someone who will love it and enjoy it for what it is. It has been completely refurbished. It’s not a true restoration, as the paint is Ford blue rather than the original Angel blue. All of the plastic parts except for the sidecovers are new aftermarket parts. It has new Michelin Gazelles, with all new tubes, rim strips, wheel bearings, and brake shoes. The muffler is a new replica. The carb has been cleaned and tuned. The fuel lines are new, and there are a pair of filters installed under the tank. It has a Shorai lithium battery, and an aftermarket headlight assembly with a replaceable bulb. Being a 1982 model it has a factory 12 volt charging system and CDI ignition.  It runs better than it looks, and it looks pretty good. The mileage is correct at 3352 miles but may go up as I will ride it occasionally to keep it running correctly.

My price on it is $1400 firm but I may consider interesting trades for certain project bikes. I am located in Eastern South Carolina and would be willing to assist your shipper or meet you at a safe public location within 150 miles of my place.

1982 Honda Passport Restoration Part 3

As mentioned before I had a request from a reader to share more of my pictures from my 1982 Honda Passport restoration So here are some of the repainting & reassembly process. Due to all the rust and pitting I sandblasted the entire exterior of the frame and them primed it with a green zinc primer. and refinished a few other small parts by various means. For the cadmium plated parts click here to see how I handled those. Although not shown here I had the front rack redone with chrome powder coat.

 

 

At the time I was taking these pictures the rear rack was simply sprayed with that horrible looking chrome paint so that I could get the bike back together and ride it, recently I removed it and had it powder coated chrome also. The wheels are still all original with just the best cleaning that I could give them at the time. Since then they have been thoroughly vapor blasted and clear coated, followed by a careful painting of the hubs & spokes.  Some of the pictures may seem kind of random but hopefully this will be of some use to someone out there trying to restore their own 1982 Honda Passport. Sorry but there are no engine rebuild pictures because there was no need for an engine rebuild, just the usual carburetor & crankcase screen cleaning, followed by a valve adjustment and a new spark plug. In the near future I’ll do a post on the trials & tribulations of dealing with aftermarket body parts for these things.

1982 Honda Passport Restoration Part 2

Cody, this post about my 1982 Honda Passport Restoration is for you!

I finally have my 1982 Honda Passport Restoration 99.5% done, at this point all I’m waiting on is some custom made decals. Apparently the tank decals for the blue paint version were a one year only special and are completely unobtainable as N.O.S or reproduction parts. Yes I’ve checked every supplier in North America, Europe, and the Orient, so unless you actually have a set in your hand to sell don’t bother telling me to check with so and so because I already have.

A reader named Cody picked up one of these in boxes and is putting it back together and asked me to share the detailed pile of photos that I took as I disassembled & reassembled this bike so I’m going to put them into a gallery here for all to see. In addition to gleaning all of the free information available on the internet you really should get a service manual. I use the Clymer Repair Manual M310-13 because it covers every small Honda with the horizontal engines up to 1999. Keep in mind as you peruse this gallery of wiring harness connector images that this is a factory 12 volt model with electric start. 1981 and older models are all 6 volt and may be different .

This is all of the pictures that I took as I was tearing it down, I frequently referred to these and the service manual as I was re assembling this little Honda Passport Restoration project. I’ll post the pictures I took when putting it all back together next.

Peace Y’all

Honda C70 Passport Restoration Part 1

Honda C70 Passport Restoration The Beginning

It all started out innocently enough with me picking up this little diamond in the rough. It obviously hadn’t run in a while and was very weather beaten. Initially I had no plans to do a complete Honda C70 Passport Restoration but you know how these things tend to snowball.

With a little help from my beautiful assistant it was soon running like a top.

Initially I had no plans to do a complete Honda C70 Passport Restoration but you know how these things tend to snowball. Let me go ahead and be perfectly clear from the start, this is not intended to be a 100 point purely stock restoration. The goal here is to produce a very nice looking scooter to use for transportation at larger events like the Barber Vintage Motorsports Festival or the Destination Eustis Motorcycle show & swap meet.

After cleaning the carbs, adjusting the valves, changing the oil etc. I took the little thing out for few a test runs and am very pleased with how it runs & drives despite the fact that it had dry rotted and mismatched tires on it. So I started ordering the pieces it was missing such as the chain cases. Where the original equipment stuff is available for a reasonable price I’ll use that, when not there are plenty of reproduction parts available on the internet from Thailand and other countries. The quality of the reproduction parts is all over the map, so be prepared to ship some things back or tweak them to get everything working and looking good.

Then one evening a few days ago I lit a fire in the heater and started pulling it apart.

In My Happy Place

One of my favorite things to do as I am pulling a bike apart is to take lots of pictures. Thanks to digital photography it is now easily affordable to document every nut & bolt that you remove if you want to. On older bikes like this that use a lot of bullet connectors it is a great idea record every single wiring connection. Sometimes there are different colored wires that attach to each other that you may not remember otherwise. There are also incorrect wiring diagrams in some service manuals for some machines so every bit of extra information helps. Plus when you put it all back together & it works right the first time, your friends will think you’re a genius!

Yes I really do use Shorai batteries for damn near everything, They’re especially great for motorcycle collectors who often let their bikes sit without running and there’s no acid to boil over and ruin your shiny new paint job. Last year I wrote an article for the Vintage Japanese Motorcycle Magazine detailing the pros & cons of using lithium batteries in motorcycles, that article will probably show up here on the blog in the near future.

Motopsyco sandblasting a Honda Passport C70 Restoration

Since there was quite a but of surface rust & some light pitting the frame & forks were taken down to bare metal by sandblasting. Since I did not remove the fork from the frame I very carefully sealed off the bearing cup areas to keep the sand out.

zinc dichromate primer

After it was completely stripped, it received a few coats of zinc phosphate primer for maximum rust protection.

Ford blue engine paint

Since this is to be a parts runner and not a show bike instead of buying an expensive urethane paint in the original Honda Angel Blue I opted for 3 cans of Duplicolor ceramic engine paint in Ford blue. These paints are very durable & hold up quite well to gas and oil spillage.

After getting all of the little bits painted it was time to move on to reassembly.

All of those pictures I’ve taken are really coming in handy to reroute the wiring harness.

fake cad plate

Figured out how to create a reasonable looking fake cadmium plate using spray paint, will do a step by step post at a later date.

engine kill switch

The switch gear was scrubbed clean and the taped off so the kill switch and starter button could be painted red again. All of the black buttons & switches still looked good so those were left alone.

I had stopped at this point to do some much needed body repairs to my truck and should be getting back to it next week, so be sure to subscribe below to receive regular updates.

1981Suzuki TS185 Finished!

Well, I got it finished! The entire build is chronicled from start to finish in the 23 minute video. I started out with a little bit of step by step video, but quickly realized that with the time constraints, that would not be possible so I morphed it into an overview video. The last few minutes is me taking it out of the yard and down the road for it’s first test ride.

It ran and handled fairly well, but the stock suspension is too light for a big guy like me to do any serious off-roading with it. I just have a couple more little things to tweak, and then if I can’t find  reasonably priced suspension upgrades, I’ll probably put it up for sale after I return from the VJMC National Rally.
