Just as I thought I had my CXTC inventory just right (one running 650T, one project 650T) and after giving away my parts 500T last Winter, I now have TWO more 500TC bikes to deal with! Pete discovered that they were for sale in my area and asked me to look at them on his behalf, but he passed on them (high asking price and expensive shipping to Nebraska being the deciding issues) and in a moment of weakness I bought 'em.

They look pretty sharp, but have not run in years (they last ran in '95 but have been stored indoors). I am looking forward to a stress-free Winter project of getting them running and returned to the land of the living. I wonder how many other turbos are sitting out of sight, waiting to be rediscovered, as these were?



The bikes belong to the father of the man I bought them from. He is the original owner of one of them (titled 1-28-82) and second owner of the other one (purchased in 1985). They are: serial numbers 1177 (5,827 miles) and # 850, with 11,786 miles. I brought them home, one at a time, without incident and cleaned the dust off of them, and they look good- but not pristine: one has a broken front fender, some kind of stain covering half of the gas tank, storage dirt on the seat , and a scratched tail section with a small piece broken off. On the plus side, there is no rust or corrosion on either bike, no sun fading, and the windscreens are fairly clean and scratch-free.

The "low miles" bike has both of its original tires, the 12K bike has the original Mag Mopus front tire (wearing out) and a replacement rear tire.



I'm going to work on the brakes, tires, and fuel systems, then sell one or both. I might take a loss on them, as they were $4500 for the pair. But it will be fun getting them going- hope there are no unpleasant surprises.



Any advice on the CXT reboot would be appreciated. I want to change the coolant- what do you recommend?

Why not make one a runner and part out the other one to help with the costs,I`m in for a clutch basket if you have a good one,lots of guy`s looking for good parts and its only going to get better as time goes on.

I cleaned the dust off of both bikes and the 11K bike is too nice to part out ,but is going to need some time and $, as it needs a new front fender, fuel sending unit, and tires for starters. The 5K bike could be a show bike, save for a few bumps and scratches. No rust, corrosion, or sun damage. I managed to fit them into my one-car garage with my two 650TDs, but I can't keep them for too long. Are the fuel sending units still available?

5K bike: put new Bridgestone Battlax BT45F 100/90-18 (56H) tire on the front+ balanced wheel. Repacked wheel bearings. Removed spark plugs, added a little oil, turned engine by hand.



12K bike: gets the 5k bike's Mag Mopus tire. I replaced the broken fender with one that I had laying around. Overhauled brake calipers, bled brakes. Repacked wheel bearings. Removed spark plugs, added a little oil, turned engine by hand.



Total spent:

5K bike: 2600 (purchase price) + 85 (tire) + 10 (sundry) = 2695

12K bike: 1900 (purchase price) + ~50 (fender) + 10 (sundry) = 1960



Next step: check out the petcocks and the fuel sending units (now sitting in a box, one sending unit is very rusty). I bought a few new and used motorcycle sending units to see if I could adapt them to work with the 500TC...





Four CXTs in my tiny one-car garage, with a '65 Valiant perched on top of them (on car lift, just out of view).

One nice thing about taking on this "twins of evil" 500t project is that It is goading me into fixing up my battered, original 650t. I pulled all the old, neglected, rusty tanks that I seem to have amassed and I'm going to restore them all at once. Goal: remove rust, fix sending units, clean petcocks, etc. Two sending units need to be rebuilt so I bought a few cheap sending units off of Ebay (for all kinds of bikes) and many will be adaptable to the CXT armature with a little modding. One from a '2000 Gold Wing will need very little modification. The best tanks will receive an Evapo-rust removal treatment and a rust inhibitor spray, as this is the mildest treatment and will keep the tanks "stock". The rustier ones will receive the POR-15 acid etch and then POR-15 tank enamel. Next step: remove the fuel pump/filters/injectors. It's going to be difficult to access those Philips head screws holding the injectors on- I'd like to replace them with little Allen-headed bolts. I took a measurement and they appear to be M5 (5mm x 18mm. I think that precise torquing of these screws will be easier with Allen heads.

If anyone is interested in buying one of these 500TC at any point in the project may do so for the amount that I have put into them- my labor, such as it is, is free!

That's a heck of a decent offer. If my wife would not kill me after crashing mine I would be all over that deal. She seems to be anti motorcycle at the moment, go figure.

After the mild Evapo-Rust treatment on all 5 tanks, I have a clearer picture of what the tanks need. All are solid with no leaks, but the two 500T tanks that came with these bikes and the 650T tank from my 650T rat bike are ones that would benefit most from the POR-15 treatment. The 500T tank from the bike that I gave away and a 650T bike that I bought onlne some years back are nice inside, and now I hesitate to line them, though the POR-15 tank liner looks like nice stuff. I relined a CL350 tank with the white Creem stuff 10 years ago and didn't really like it, but I've used the POR-15 enamel rustproofing on car antique cars and it's amazing stuff. I can't wait to see how the tank sealer looks. I've done all the prep work up the the drying stage before applying the tank sealer, so it's decision time about whether to seal all 5 tanks. I bought the entire kit plus an extra quart of sealer so I could do all the tanks if I want to. This process was fairly laborious, and it's not done yet!.

I'd do them all at once since they are ready and you have all the equipment. Sooner or later they will all need it if not kept in proper working order. I can't see it bringing the value down at all if done properly. My $0.02

The treated tanks are in the basement. Haven't made any progress on the bikes, too busy and not much space to work. But they are warm and dry in my one-car garage. I was going to use one of the two as a daily driver so I didn't put so many miles on the 650TD, but in the interim I got a 2005 Suzuki DL650, and I love it. I put 9K glorious, trouble-fee miles on the CXT last year, but now will ride it as a special treat only once a week, and not in the rain and ice as I have been doing. I regret spanking the 650TD every day and putting so many miles on it, but it was so much fun, and really cheered up my working days, which can get me down. The DL650 is lighter and quite quick and nimble on the city streets, and riding position is similar, so switching between the two takes little mental adjustment, but it doesn't have the CX650T's power and fury on the open road.



Oh- out of the blue, the former owner's son mailed me one owner's manual, a shop manual, and the second enameled key for one of the 500TCs two months ago! I've got to write him a thank-you note, I've been neglectful!



So my bike complement is now:

working bikes:

2005 DL650: working, added center stand and heated grips, is my daily driver.

1983 CX650TD: bought 1 1/2 years ago, had 9K miles, now has 18K miles, runs flawlessly. Now a once a week treat.

1972 CL350: A running basketcase, in a shed in central Maine, use it every year for 2 weeks on trails.

Not running bikes:

1976 Kaw KZ400, outside, needs restoration, may never get to this project. Why do I still have this?

1974 CB450: Outside, runs, no title, bought at dealer auction. Hard to get title in VA, may part out.

1982 CX500TC (2): what this thread is all about, both LOOK great, we'll see how much heartache they turn out to be.

I don't know why I bought them, turbo fever I guess. I like having them around, though.



1983 CX650TD: My original one, bought 12 years ago, hasn't run in 5 years, was outside for years, now that I have a garage it is inside and waiting its turn to be brought back to life. It's ugly. But it was awesome to ride, and I sure it will be again. This is the one that Dan Topping replaced the stator on in '2000.

That's eight bikes, I guess I'm sick. But do I want a cure?

If your sick then I think a lot of people on here have similar ailments...

Awesome stable!!! What a collection of turbos!

Re: your comment about hard getting titles in VA - can you elaborate? What is the process or difficulty? I moved to VA about a year ago and see so many tempting deals advertised with the "no title" qualifier - I have always kept away from them.

Where are you located?

Keep the updates coming.

Thanks Dan and Tom, I'm in Fairfax, 10 miles West of D.C. I bought the CB450 at a great price from the local dealership's annual bike auction nearly two years ago. They are trade-ins, consignments, etc. It was listed as "no title" but I got a bill of sale from the dealership, paid VA sales tax, did a DMV title search (no records), but the VA DMV still wants an existing title or I can't get one. I gave up trying last year.

Have you tried submitting a VSA-12?

O.K., I'm tires of these two project bikes taking up space in my garage, so I'm getting to work on them. I pulled the entire brake systems off of both bikes and am rebuilding them. They are really bad... hoses clogged with dried brake fluid, really nasty. I've decided to do a full resoration on 500TC #1177 (5,827 miles) and dismantle bike #850 (the one with 11,786 miles). I'm not parting it out though, merely cleaning every part, putting them into boxes for storage, and putting the engine and 50% stripped frame in the basement for storage. I'm photographing every step along the way and labeling all the fasteners + putting them in ziplock bags. The engine is coming out of #1177 too, for a coolant seal replacement (I figure that the stator should last, since it has only 5K miles). I want to keep it 100% original, however I may repaint the mufflers and put a Dan Topping oil cooler assembly on it to help protect the stator from high temperatures. So far I've got the fairings and brakes off, and am now pulling the engines.

You don't need to pull the engine out of frame to replace the water pump seal on the CXT.. Leave it in there and just replace the seal.. Not too bad of a job..

Maybe I'll leave the engine in the one that I'm restoring then... I'm pulling the fuel pump, filter, and injectors to clean/inspect them, might pull the forks (even though they are not leaking, with 30 year old seals and fluid, they probably will, once the bike is in use). Lots and lots of work to do...

Paul, Keep the amish rally in mind since they didnt' do a turbo rally this year. You would fit in with the rest of the ecentric folks.
