Sweet old bike! Son of Weldangrind would like to find something just like that.

I believe I had my 200 to an indicated 80mph on the flat blacktop road going into Doon, IA. It took about 2 miles to get from 65 to 80.

That sound.
Mine looked just like this. Less the sissy bar and the girl. |

I finally got my fork seals changed and took the bike for a test drive and the throttle stuck. It turns out it was the left carb.
The slide is simply too tight in the bore. I cleaned it and the bore to no end with no improvement. I have an extra slide and it too does not fit in the bore (too snug), but the same slide fits fine in another old carb body I have laying around! WTH!? How could it work before and not now?? Strange, the same thing occured on the opposite side already! I 'fixed' that one by putting an old slide in. The bike came with two old carbs and slides. I suspect the little 'peg' on the side of the carb body bore is too wide or somehow damaged and hanging up in the groove of the slide but I don't know. :roll: Has this happened to anyone else out there? Any ideas? I was thinking about 'polishing' the little locator peg somehow but I don't want to damage the bore. I could also 'polish' the groove in the slide, but again I don't want to damage anything.

A Google search and I got my answer. I overtightened the carb body. I just loosned it up a hair and all is well.
I have a case of OCD I wouldn't wish on anyone. This made me nuts tonight.

I can appreciate the OCD.
Which part of the carb body was too tight?

Where it mounts to the aluminum intake 'manifold'. Apparantly it overcompresses on the O-ring and microscopically distorts the carb body and throttle sleeve bore. :?
I loosened it a hair and all is well. That was a new one on me. Always learning. God LOVES to keep me humble like this. :?

I'll benefit from your experience. I never thought that I might be over-torquing the carb fasteners. Better to rely on Loctite I guess.
Or lockwashers. The guys on the Honda Twins forum say to just use 2-3 ft-lbs and lockwashers. I got the bike back together and it rides sweet. New fork seals, fuel lines and fuel filters, new O-rings in the intake tract. Next step will be having a shop match the paint and bringing it in for a partial respray. The Linda learns to ride and I'll either keep it for her to use or sell it. I'd like that CB400 SuperSport...

How odd is that, my last post showed up as being from W&G. :?:
Anyway I rode the little Honda to work today. What a sweet little bike. Praise God it appears all the work I did to it was effective and it runs great. It's fun to commute on. It's more fun to ride a small bike at WOT than it is to idle along on a powerful one, especially at around town speeds. I hit 70 on a short straight stretch with no wind, and the bike had a few more MPH in it. :P You should hear that little bike above 7,000 RPM. It sounds like an Italian sports car. Redline is 10,500. 60 MPH it about 7,500 on the tach. :wink:

My guess is that you hit Edit instead of Quote; I've done the very same thing.
Glad to hear that the little bike is a good performer. How about some more pics?

You all deserve more pics, but I'm waiting for paint :wink: .
I had some custom matched today, and hope to have it done in the next week or two.

UPDATE:
The bike seems to be a winner. O-rings in the intake tract were replaced. I apparantly overtightened the carb mounts and the slides were sticky but I have corrected that and they move well and there are no vacuum leaks on the starting fluid test. I replaced the fork seals. That went well except I (stupidly) pressed in one seal BEFORE I repalced the bushing and it was a PIA to remove it and put it together right. I was able to do it without damaging the seal, Thank God. I replaced the fuel lines and fuel filters and gave it a bath. It's fun to ride. Pretty smooth and it makes great sounds. It sounds like an Italian Sports car, even though it's pretty slow. 60 is fairly easy, and I hit 70 (GPS) on a longish straight leveel section of road with no wind. That's rare in my neck of the woods! It seems to get about 75 MPG, which is about what I'd have guessed. I had some custom base coat/ clear coat paint mixed up and hope to have that done soon. I have sourced side covers, and cleaned up some electrical connections. Other than that it looks and runs beautifully. Will post some pics soon. Bill
