So you bought a CM400 / CB400T, now what...(50+ Build Links!)

Looks like a stock CB tank (450), I believe the later versions had the knee dent look to the sides, compared to the earlier models.
 
yes, it's a cb450t tank from 1982....my bike has been through a lot since that picture. should be street legal within the month and ready to ride.


here's a recent pic:

Hey all I am looking to replace my front caliper with an upgrade...I saw on one of the posts what looked like a brembo but any tips or leads would be much appreciated. I have a 1978cb400tii
 
Fixing the previous owners mess up

I bought a 78cb400t that I am turning into a brat style and the more I dig into it from the previous owner the more I seem to find that he jacked up on it. My latest discovery is that I think this was supposed to have a push pull throttle right? He only has one throttle cable currently. I also found that he disconnected the choke. Does anyone have a picture they could post of what theirs looks like? I have the clymers manual but the pic doesnt really seem that clear. Also if you could confirm that it is supposed to be a push pull throttle cable that would be awesome too.

That's not uncommon. I removed the "push" cable from my bike, too.
 
no,sounds like a bad cable/cable binding or spring on carb. Its just for the return.
 
So what did you end up doing for the brake linkage set up I have seen you thread before and have tried to make sense of it but have never been able to get a clear idea/ view of how you worked around it. I need to rig something up on my Nighthawk build and I know the frames are similar as far a shape and peg placement. Thanks and you built a great looking bike thats for sure. I am in Mesa If you ever want to go ride to canyon lake hit me up for it.
 
Thanks,its a pocketbike transmission. the lever turns gears and moves a lever on the back
 
Anyone know what carb Justin used on his 400? I'm wondering if its just an FCR 39?

EDIT: probably a 41ish, hmmmm that would eliminate any tuning problems. they are a breeze to setup
 
suppose I should toss this in here as well. My '83 CM450e

Just getting started on my cb400 build. Between work and school I don't have too much time but every bit I do have is dedicated to the bike. I'm leaning rat/cafe/brat masheup right now, but who knows where this thing's goin!
 
Did someone figure out how to run pods on these things?

I've been away for a while - this was a major issue when I was building mine, I had a hell of a time tuning the carbs from 0 all the way up to half throttle. My 400t's just been sitting for about a year now, I had intended to re-install the factory airbox.

Try this link. I used it to set mine up to run IAC's. Still need to do plug chops on mine though...

I gave up trying to tune for pods. I upped the jets and shimmed the needles. It didn't seem to make much difference. In the end, I decided it was more important to get the bike running right rather than looking cool. If you are going to run pods I think you need to get good ones, i.e. K&N. The cheap ones (that I had) block airflow due to their design. Someone (maybe Sonreir or CrazyPJ) did a nice writeup on why these things don't work. If I had the money I would love to try converting over to Mikuni carbs and K&N pods. Some people seem to get them working, but I'm not sure how.
 
if you read the thread i posted you'll see there were two, or more, different carbs that came on the CM's a three jet style and a two jet style. This makes a huge difference in the decision to go to pods.
