And so it begins, bringing the 65 CT200 back to life

I had posted a while back that I had acquired a bike like the one I first learned on back when I was 8 years old.

So I finally got it home this week. Here's a couple pics of the little beast. Overall pretty decent shape.

Only part missing that I can tell is the engine skid plate, easy find on ebay.

I've kicked it over and it has pretty decent compression, Tank only has a light coating of rust inside so a bit of electrolysis and it will be good.

I took the carb apart last night and the news was not so good. First off you know you're in trouble when every screw on the carb is now an SAE, or just spins freely. Got it apart and the post that the strainer screws into is almost non-existant. just corroded away. Same with the posts for the float pin and the post that holds the main jet / emulsion tube. There are chunks missing and just enough threads to hold it together. I'm hoping it's good enough to at least try and get the motor running. These carbs are pretty unique. The OHC bikes as well as the street only C200 had different carbs. So these are only unique to the CT. Not much available on ebay except a supposedly NOS one for $350. I'm wondering if that alumaweld stuff would work on a carb body? I had used it before to rebuild an ignition switch housing on my RT1B project and it worked great, but that was some cast AL, not this pot metal. Although it's supposed to work on this type of stuff. I think I have some old carb parts in a bucket and might give it a try. If so, I can rebuild those posts and might salvage this carb. I've already tapped to the next size metric some of the stripped holes. Slide and brass all appear good.

Next step is to get a small 6v battery and start to sort wiring. The PO wasn't a total idiot. He added a separate fuse holder mounted in the side cover as well as a charging port. The wiring is pretty decent for a 50 year old bike so shouldn't be too bad to get the electrics sorted. Hope to see if it will run this weekend then I can tell just how much more work I'll need to do.

I did confirm the speedo still works :) so the mileage might be actual, 3200. It still has the original style tire on the front so it just might be good on the miles.

So so far I know I need:

Rear shocks
Skid plate
Carb or parts maybe
Tires
rear brake cable
Muffler or possibly some detailed repair work.

I'll keep this updated as I go.

air intake tube was split in a few places, covered by old dry electrical tape. So..off with the old tape and pulled out the self vulcanizing 3m electrical tape. This stuff is tits for salvaging old rubber intake tubes and stuff. Wrapped the whole tube up and it's good for another 50 years.

Just more of an FYI for anyone who needs to try and salvage some old rubber intake tubes when new ones are unobtainable or big $$$$.

Started work on electrical, namely to try and get a spark out of this thing. First thing, hook up battery, pull the plug, and just see if there is a spark. Nope.

So start by bypassing all the harness, hook battery to coil and try again, nope.

So pull coil and bench test coil on it's own, yup it will throw a spark.

Never a good sign when you pull a cover off and water runs out of the dry side of a motor. I've seen worse but still :(



Test condensor, tests ok

Points are dirty, clean points, no spark.

Pull advancer off as it was fused solid with rust apparently, that took some work but it loosed up. Kind of pitted but it will make the bike run and I'll look for a new advancer some day.





So put back together, set gap, static time the points, cleaned electrical connections, trimmed the high tension lead back and reattach the cap. Hook it all up and bingo, nice spark. With points on end of crank, even on a single cylinder this is a wasted spark system. Later 90's with OHC didn't have that.

So...next step, drop the oil strainer and check for chunks, clean, fill with fresh oil, add gas, and try to start it. That will happen this week.

BTW, found a source for a very very nice carb body so I'll keep the old one as spare parts.

Wow, 50 years old and 3200 miles. Nice find. I don't know what it is about these old hondas, but I may need to get one.

I actually think it might be original miles as the Speedo does register. with the original front tire and some other things I'd believe it.

But...when I removed the gas tank the original mounts have been busted and the whole bottom of the tank was brazed so I have to pressure test it.

My BIL who hauled this down from Michigan informed me that his Uncle has an old Trail 55 tucked away in the back of a barn that he might give me.

Just what I need, but I would take it, we shall see. When it rains it pours. I'm picking up my Dad's R75/7 this summer, and he said he found a 74 750 Honda that he can get for $100, supposedly all there with title. I'll take it at that price and flip it. but as my wife says.....YOU NEVER SELL ANYTHING. We shall see.

I just love to work on old bikes and bring them back from the dead. They can challenge all you know about mechanics and body work etc.

woo hoo, it lives.

I pulled the sump cover tonight and cleaned the strainer. No chunks. Just sludge as I would expect. Put it all back, filled it with 20w50.

Then poured some gas in the tank to see if the brazed bottom was going to leak, no wet spot so good enough to try. Hooked up a fuel line, jumpered a battery up to the harness, choke on, fuel on, the friggin thing started first kick. Had he choke on though so it died out. Took the choke off and bingo, it's running again. set the idle and she's ticking away. literally and quite loudly. Turned it off and check valve lash. Intake was way way way loose. Set the valves and started it again, nice and quiet. Shifted through all 4 gears just fine.

But.....no oil coming out of the squirters on the valves. So I shut it down. Time to trouble shoot the oil system. The motor was so quiet though and no chunks down below so I'm sure everything is good, just need to find a diagram of the oil circuit and trouble shoot.

But.....she runs and seems to run very good. No telling when the last time it ran. Another milestone.

Next step, make sure it's oiling ok then check to see if the charging circuit is working.

Still no oil pressure. Pulled the pump. It looks good, no abnormal wear. I reviewed the oil flow diagram and pulled the top right cap nut on the head, no oil flow there. Pulled the clutch cover, no oil flow there (should be).

so looked through the parts lists etc. and no oil pressure relief valve anywhere in the system. So I'll use various methods to force pressurized fluid into the system and see where the problem is. May end up pulling and splitting the motor. Bummer as it runs so good and is so quiet.

Pic of pump.

think I found my oil flow problem.

I ran it again today and verified I had good oil flow even just with kicking from the pump to the mail oil galley that runs left to right on the bottom of the motor. But.....running the motor for an extended length of time still showed no oil on the right side.

I pulled the pump back off and used air to blow through galleys. Could not get air to pass left to right. Pulled the clutch cover off and could get air to pass from clutch cover galley to rocker box no problem but still no oil running through slinger etc.

So...pulled the right side engine case off. Could blow air through the main galley now left to right, through right side engine case up to clutch cover, etc. etc. etc. No blockages found. WTF.

So took a break and went to vacuum the pool out. Then bam, dawned on me, what about the right side cover gasket. Went back out and sure enough, it's missing a hole that would allow oil from the main galley up to the slinger and to the rocker box.

I'm pretty sure someone had been in the right side of that motor based on what the screws looked like so hard telling how long it's been that way. I'll have to pull the rockers and pins to see if there is any serious wear.

but...at least I found the problem. Here is a pic of that fucking POS gasket.

I swear sometimes these companies just like to screw with us.

You can clearly see there is no hole to allow oil into that short galley in the cover.

Wow! Brings back memories. My first bike was a white one like this. It was a '64 that I bought used in '67. That one appears to be in good condition. Good luck with it!

I think its 90cc, the "touring" version.
The guy I bought it off had one like yours but wanted 2K for it, he also had two Motorcompos. The fold out Honda that came with the Honda City.

I have a '67 and I first thought the same thing, "oh I'll just upgrade the forks"! I don't know why I thought that, but I ended up just restoring the originals and I have to admit, they run wonderful. I love the setup and wouldn't trade it if I was given a set of modern ones.

I did hybridize it as it was a CM91 (road scooter) but I liked the CT90 better so I did some swapping!

Also, I ended up restoring the original engine...it's not so powerful but I do love the little sucker. Such a fun tiddler.
