I came across a couple truckloads of Trail 90's and parts, and figured they would make a good project. In the beginning: Then some new paint: New shoes, with clean rims painted to remove friction and rim strips: Rebuilt transmissions, wrapped and waiting for installation: Engine cases cleaned and sandblasted, I may black out one of them but I kindof like the raw look. Replaced the phillips bolts with allen heads, especially those for the cases and parts that will be taken apart often. I've ended up with a ton of extra parts listed here: http://hondatrailcts.yuku.com/topic/3817/Lots-of-CT90-parts#.Tho0NM1szIY PM me if you need anything.
I'd love to see a pic of the green one when your finished. What a neat find. And you seem to be gettin' a really great kick out of restoring them. MSL
Waiting on a set of forks I ordered for that one -- I'll put more for it up when they're in. In the meantime, assembly continues on the others . . . The spark advance on the points ignition -- it basically rotates the cam that triggers the spark so it fires earlier when the rpms are up (the piston is traveling faster, so the spark needs to fire earlier so the combustion still happens at the appropriate time). What a cool mechanical way to do it.
The assembly is underway. Electrical problems I find are some of the most frustrating, and many of mine stem from bad ground connections especially after a new paint job. So, as much as it pains me to grind away new paint . . . this is for the ground on the coils: And a new big bore 54mm piston and cyl: Rectifier upgrade:
I just traded for a 1969 CT90, it's hard to believe this thing is 42 years old and still runs like a top. These are great little machines.
Before I let out the suppressed giggle, first let me say a big loud "good onya!" for doing the resto's, well done man, they're coming up real nice. I like the white paint shown, dunno if it's just primed/painted/whatever, but I rekn one of those old girls in white would look pretty good. I'm glad I'm not the only one who's come home with boxes of junk that apparently resembles a motorcycle. Oh yeah, the giggle..... I think I might be a bit older than you. I used to hate those things, the sooner I converted everything to Dyna the better! More pics when you going through it all, I'm very jealous of your find! That lot would keep me amused in the shed for ages.
Oh yeah, almost forgot. When you do the next bike electricals up and are looking to provide a decent earth (very important, as you already know), you might like to give these a go...... http://www.wurth.com.au/catalogue/A09_6241.pdf No need to scrape away paint, lock the bolt in against rattles, really digs in to the parent metal for a good connection, and hidden under the bolt-head out of sight. Have fun man!
That's a good suggestion, have lots of those! ------------------------------------------------------------------------------------------------------------------------------------------- jtn, I like the pipe, is that a VW tip on the can... Any details?
I'm not sure where it came from -- perhaps an aftermarket VW tip. It was in the buckets and buckets of extra parts I got with the bikes (why is it that every CT90 ever sold also comes with a milkcrate full of spare parts?)
If you're wondering why this 'finished' one doesn't seem to go very fast (other than downhill) I can probably offer a little advice... Nice work!
Just in case you don't already know, the dual sprocket setup belongs on one of the older CTs without the dual range box. No reason to haul around that big heavy sprocket, plus the small sprocket it fits over is 40 tooth where it should be a 45 tooth for engines with the dual range box.
Now on to the next one -- decided to try out a new Lifan 150cc engine in this one. I'll be adding some other color to the frame, the brown didn't turn out as good as I thought.
