RE: A quick look at my bikes turned into all about a CT200 Honda :)

TT-R250M · Super Guru

After a few laps around the yard and half-hearted wheelies the CT200 has gone downhill at a fast rate. It started blowing smoke in a big way. I was hoping to put it back into service for awhile, it seemed okay from an external inspection but it is time that the rings were done. I will also be lapping the valves (after replacing the exhaust valve), new oil seals, gaskets etc..

Here is a couple of pictures of the valve compressor that I made from an old G-clamp, an old WR400 suspension linkage collar and a piece of wire-

I didn't bother welding it as I can still use the clamp this way for its intended purpose (usually lying around collecting dust lol). Works a treat!

I was wondering why you didn't weld it on but I guess you can use a clamp a lot more often than a valve compressor wink

Considering the amount of views this thread has had I have decided to upload some pic's of the finished product (just about) . Just need to find tyres the right size, put them on the new wheels, add a universal chain tensioner and speedo cable and cable guides. Anyway, here it is, bit of a change from what it looked like originally-

Notice the TTR250 rear taillight/brake light? wink

Enjoy!

Nice work.

What year is this CT? Does it have a compliance plate? I'm trying to work out if the CT200 was in response to the Yamaha AG200 or the other way around. I think Honda was first with a lot of AG stuff with the CT125...not sure.

TT-R250M · Super Guru

Thanks, it was a lot of work but worth while.

It is a 1987 model, you just reminded me that I need to put the compliance plate back on after the paint job.

According to the info that I have (not a lot on this bike) the first CT200 Auto-Ag was made in 1984 and finished production in 1993 (but they may have continued on making them in AU?).

Thanks Brian.

I am just glad it is nearly over now as next is my car.

I am glad that I have a passion for making old things look new (like yourself) or this would be hard work. smile

Looks really good Jarrah, first shot of this bike looks quite different than now.
It may just be the camera angle (or my hangover), but is the throttle cable pinched a bit near grip?
Is there a mud flap for the rear tire? (or maybe I missed it in one of the shots)
Are you going to paint the manufacture (sorry, can't say it man) on the back of seat?
Good reading bro thanks for sharing

Thanks Greg

Not sure what you mean by ''the throttle cable pinched near grip?'' but I can assure you that it is not pinched anywhere. I do need to buy cable guides and make brackets so the cables don't rub though.

If you mean a fender mole like the one that dangles off the rear of the front fender- no, I am planning on making one from rubber. It does however have a mudguard that stops the rear tyre from flicking mud/rocks at the engine if that is what you mean? (hardly visible in the pics).

I will probably recover the seat soon with the Honda logo on the back (if that is what you mean?).

I guess it is just way one of the pics looked to me, I thought the throttle cable had a hard angle to it but I'm rong wrong.
The mud flap I was talking about is the piece in front of the back tire to block mud from engine. I guess its called a mole, sorry.
I just figured with that seat being so nice, you may have a stencil you could spray on yourself, since you seem to be handy with the spray gun.
Ya know what I mean? smile

TT-R250M · Super Guru

Hey Greg,

Pictures can be deceiving, I know all about that from evilBay. biggrin

Here is a few more to satisfy your eyes-

2014-06-08 00.04.00.jpg

This should clear up the ''mole'' misunderstanding smile -

That dirty mole got you again aye (couldn't help myself). biggrin biggrin biggrin

The seat is still quite good so I will probably leave it like that for awhile longer. I do not like spray painting vinyl as it has a tendency to wear off quickly. Besides, a new cover like THIS is cheap enough. Ironically enough, the seller also mentions about the spray paint on vinyl lol. smile

Hope that helps my fellow companion from over the other side of the BIG fish pond. smile

The fully enclosed chain covers will be the hardest to find...it's the first thing farmers seem to rip off on the Yamaha AGs

Got that right in one! I have not found one anywhere and I mean anywhere! Even if I did I would have to chop on an arm and a leg at over $100 RRP new for each piece, 3 pieces in total (one which is a little cheaper). I am going with the homemade fully UN-inclosed version lol with a universal chain tensioner.

Also got that right, it's a 1994 EF Falcon that I am putting full XR6 running gear through with a typhoon body kit, it won't happen over night though (like most adverts claim). biggrin

That's two Kudos to you, now I'm off to find the Kudo function.

I will keep my eye out for a set around here. Bike was pretty popular with the farmers in this area.

That would be very nice of you, thanks mate!

I also need a CT200 exhaust as the one I have on is VERY restrictive and makes it run rich. I do not have spare jets ant to have to go smaller on jet size is not a good compromise.

Cheers,

Jarrah,
Did you have any trouble with rust in the tank? (I have a HORROR story of what it did to my KZ650)
I'm sure you have it sorted if there was, just curious to what you did on this one (if anything)
Greg

TT-R250M · Super Guru

I actually replaced the original tank for one with less rust. It had more dints than the original but in better condition for rust. However I did still use a 3-step tank sealer to stop any minor rust from getting worst, you will see it below. It cost me AU $59.00+ AU $20.00 postage from the US and worked a treat...

It is silver in color-

Actually off the topic of the mighty CT for a moment, I actually really like the job you have done on the WR400. I actually think that these early WR and YZ 250/400Fs are going to be really hard to find in years to come and be collectable. They started the 4 stroke revolution (for the masses) and not just for Yamaha, all the manufactures had to respond. I have been looking for a clean one for a while now. The 4 strokes aren't as tolerant to neglect like the old 2 strokes so most of them I see are packed in boxes!

TT-R250M · Super Guru

Thanks Jim, glad you liked it.

IMO- there is no better WR model than the WR400f, it is light weight and packs a punch, even standard. It has a higher top end than my mates WR450 2006 model, even though my rear sprocket is three sizes larger and the front is the same. He has slightly more grunt down low but his has modifications done to it, mine is standard with the US exhaust. Pulls a top speed of 170 kph with 14/50 sprockets!

I love my WR400 and would not sell it for the world! Spent over 5 grand now so it's a keeper anyway, would never get back what I spent rebuilding it.

Jarrah

P.s. I got sick of calling you Agman so I looked on your pro, hope Jim is correct.

AGman · Veteran Member

Yes, the 426 & 400 were both a bit raw. Another reason why they will be sought after I think.

Don't suppose you did a write up on the rebuild anywhere on the net? If you threw $5K at it I'm assuming you did a thorough job on it so it would be interesting to see some info on the job.

Cheers
Jim

TT-R250M · Super Guru

Hey Jim,

I did not do a write-up anywhere on the net, after doing the write-up on my TTR250, I thought I could do with a break from editing and such. Besides, my last attempt was shocking not very readable and to this day still needs editing for spelling mistakes and bad grammar lol. biggrin In my defense- I was in a bit of a rush when I wrote it though. wink

The list of things that I did was-

2001 WR426 frame powder-coated in Space Blue (the old one has rust cancer holes that I fixed but was still not happy with).

Repainted motor- the bottom-end I spray painted with metallic silver that I mixed with black to darken, the top-end was hand-painted with a cotton tip (it's hard to get my friends to believe it though lol).

2001 YZ250 swing-arm (the old one was worn through at the bearing case badly), touched-up it up with paint and put new bearings and seal, slider, chain guard through it.

2001 YZ426 forks- were in mint condition so only polishing was unnecessary necessary. Bought new cable holder etc..

2000 YZ400 rear shock (that's why it's yellow not silver like the original one).

Fitted new bearings on triple grips (had the bottom fitted at my local mechanic for $30 to save the trouble).

Checked valve clearances- spot-on (the engine was fully rebuilt with a new gearbox before I bought it, another reason why I bought it).

2001 WR426 carb- hated the 1999 version.

Full carb kit along with a new intake rubber.

2001 WR426 US exhaust- repainted it in high temp.

New over-size radiators with new genuine protectors (one protector was not on yet in the pics).

2003 Takasago wheels (not shown in pictures)- the 1999 ones are just the DID's.

New plastics (apart from the radiator shrouds as these were newish anyway).

Fitted a new snorkel- the old one was non-existent from the PO.
New OEM headlight unit and cover/shroud.

Factory Effex Evo 10 graphics kit (I'm pretty sure it was 10 anyway).

New chain and sprockets (14/50).

2001 front and rear complete brake system (mint condition) with a brand new rear master cylinder.

There was more to it than that like new bolts, wheel spindles/axles, and all the general hardware stuff, but that should be all the main things covered.
