1981 CM400T Project

I'm hesitant to call this a "build" since I'm not going to be stripping it down and starting fresh, even though it could use it. Yet.... This thing is my daily commuter and I can't afford to having off the road for a long period of time. Anyways, I picked it up last October and decided right away that I was going to give it the cafe treatment which was inspired from building this, http://www.dotheton.com/forum/index.php?topic=48346.msg536579#msg536579. I quite my job and went back to school, so I have to try and keep this as low budget as I can. TRY!

This picture is how I received it, with the exception of the seat. It had the torn up original on it. I purchase this new foam and cover off of ebay and installed it over the original pan myself until I could get a better seat setup.


I was horny to put clubman bars on it, so I bought a set and also got a Rocket 4 seat for my future plans.



These two are more recent. I rode up to the inlaw's and did a bunch of maintenance and painted the pipes for shits and giggles. New oil, chain lube, filter, blah blah blah.





I live at a marina, so my work space is quite often the same place that I park it. I just adjusted all the valves and had to zip tie my old ranger blanket to prevent anything from blowing into the bike. It's always a bit windy and it was necessary. This job was a nightmare! Once I adjusted the valves, I started torquing them down to what the factory service manual dictates and SNAP! The local salvage shop is only opened two days a week and I needed to get the bike ready for a trip I'm taking soon. I had to pay $12 to get a new tappet screw rushed in from a local shop to insure my bike was ready to go. As I was installing the new tappet yesterday, I noticed that two of the other tappet screws are twisted and about to snap themselves. Something I should have checked prior to ordering..... Luckily though, the salvage shop was open yesterday and I bought three more (one more for safety!). Everything is adjusted and looking good now and all I had to do was put the valve cover back on and SNAP! Valve cover screw.... What ham fisted knuckle dragger was working on this thing before!? Really! Back to salvage.... Luckily for me, the bolt that snapped off was well lubricated and easily spun out with a punch.




I'm taking a huge amount of inspiration from fresh_c's Ugly Duckling build (http://www.dotheton.com/forum/index.php?topic=36439.0) and I plan on making a very similar seat frame for my rocket 4 seat. Eventually, I plan on hiding all the electronics and battery under the seat as well. I purchase a '77 CB400f tank and I'm looking forward to making that work with my bike. I'm trying to gather as much info on this chrome paint from Spaz Stix as I can and hoping to paint both the tank and seat with it. All the images online and videos on youtube look very promising and they even claim it can be used with a 2K clear for protection. I've emailed them with a few questions, so we'll see what happens.

For now, here's a VERY crude photoshop example of what my bike will look like with the new tank and seat combo (minus the paint). A set of Viet's rearsets should be in the near future as well.
 
Hello brother Danno,

As you are beginning your build I am fine tuning mine.

If you have not seen it yet I started a thread almost 2 years ago because I couldn't find many builds on this group of Gen 2 Twins. It has now grown to a list with links to over 50 Builds on page 1 and place to gather around these bikes.....42 pages of Ramblings.

A link to the thread "So you bought a CM400 / CB400T, now what...(50+ Build Links!)" is in my signature iat the bottom of this post. You will also finda link to my build, that I am proud to say has resulted in a nomination for May Bike of the Month..

You will find the frame really doesn't lend itself to a classic cafe straight Tank/Seat Line due to the Cruiser style "Drop" or "Broken Back" frame.

A lot of guys are now doing complete sub frame fabs to get rid of the drop seat frame, and is the coolest way to do it in IMO. Others let the seat upholstery drop down and cover the gap, (much like your current/oem seat pan does) a few have filled the gap between the frame and seat line (That is what I did) & it looks like that is what you may have in mind.

I'm not found of the Tear shaped tank either and swapped mine, is that a CB200 tank your thinking about?

I'll be watching and reminiscing.
 
Thanks Frankenfe. Your CM400 page is one of the first topics I read on this website. You put some great links together and your CM turned out great!

The CM definitely isn't the best cafe candidate due to the frame, but can still be done with spectacular results as many of you already know. I'd love to do a sub frame, but I don't have the time or space to take a project like that on. I'll do something similar to what fresh_c did for now and hide everything under the seat.

The tank I bought is a CB400F tank and I really like the look and size of it. I'm very much considering doing the tank with Spaz Stix Mirror Chrome and have a little more research to do before I commit to buying some. I'll definitely document the paint process if I go with it.

But for now, I got everything running really smooth and just rubbed in a new set of Kenda Challengers. Thanks for having a look.
 
I have my CB400F tank now and have to start looking at paint options. I haven't had a chance to mock up the tank and seat on the bike yet to see what it will look like, but I get pictures when I do. Next step is to make a seat frame for the Rocket 4 to sit on. I'm thinking that I might have to trim the front of the seat to shorten it up. We'll see.





 
I'll be following this one.

I ordered rear sets from Viet for my CM450 and they bolted right into the passenger peg location. The only thing I had to do was cut down the mounting bolt, since it was too long and hit the swing arm.
 
Nice "Bits", How do you plan to deal with ......

Good to know. Do you find them to work in that position?

Ahhh, everyone's favorite part of the CM400's frame.... I'm going to do something along the lines of what fresh_c did. I like what he did and think it looks good.

The other option is to completely close it off similar to what you did. I'd love to chop that whole section off and start fresh, but I don't have the time or place to take on a job like that.

I approve! Lithium battery for sure. It'll fit with a little tweaking ;)

The hump on this tail section is almost big enough to hide a car battery in there! The hardest part of this whole thing right now is finding time and I'm itching to get new tank and seat done. I'm chasing leaky gaskets right now.

I haven't hooked up the linkage yet since my engine is still at the shop and I need to do some work on the rear brake, but the actual mounting looks good, the clearance of the levers looks good, and just eyeballing the location of the linkages look good.
 
I've been riding around town without mirrors since I've installed my clubmans and knew it was only a matter of time before the local police noticed and pulled me over. I searched around for bar end mirrors and continuously spat coffee all over my computer screen in disbelief of their costs. I know, I know.... You get what you pay for.... But, I need to keep this relatively low budget. I found these eBay bar ends (as I'm sure many of you already have) and ordered them.




They seem pretty solid and I don't foresee having to continuously readjust them as they tighten down pretty good. As you can see in one of the pictures, the finish has already started to get stone chips. Not a concern for me, but maybe for some. The one major gripe I have with these is the tapered nut that goes into the bar and tightens the mirror down. This little "metal" tapered nut feels like it is made out of butter and I mangled the right side one trying to get it tighten down. Almost to the point where it was US. Other than that, I'm happy with them.

I think I posted previously that I was taking the bike on a little trip and I had to get the tires replaced. The ride was about 600km with 100km (each way) being really twisty through the mountains. If I remember correctly, the date code on my old tires stated that the tires were from the mid to late 90's and that concerned me a little. My rear tire would kick out every now and then even riding through town, so the idea of laying my bike down on a mountain was a little unsettling. I ordered a set of Kenda Challengers for about $120cad which seem to be a popular budget tire and got them on the bike. I took them for a little ride to rub them in and the felt worlds better right off the bat. I had to put a good amount of weight on them to balance them, but I can't expect absolute perfection at that price.




I wouldn't call myself a great rider, but the new rubber instilled a lot of confidence in my cornering ability and allowed me to get a better lean than I would have ever gotten before on this bike. That stretch of twisty road couldn't have been a better test for these tires and I'm thoroughly impressed. Two thumbs up for these tires.
