Had the carburetors on my 400/4 cleaned out the other day. I must say running really well now. While I was there the mechanic who did it said that my rusty spokes would be an MOT failure. He mentioned something about a wire brush. Just wondering if I rub off the rust and crud whether that would be ok? Can't see how.
Any tips on sorting out spokes?

Just read the "it's a shame" thread. That's exactly it.

Panic over. Noticed that the stuff wasn't baked on as I thought it would be. It had a slight sticky feel so I thought I'll try paraffin on it to dissolve it. Just wiped straight off.

Just been out on the 400 four tonight and noticed my cover has stuck to the outside downpipe and left the pattern of the cover on it. It's a Hein Gericke cover in the material they make cover up overalls out of. Obviously covered it up too quickly. It doesn't exactly look like anything's melted onto it but obviously something is there to leave the pattern. Any thoughts on how I can remove it? I'm mortified.
Also, if I can pick your brains. I noticed as it got warmer it was getting more difficult to pull away as the engine feels a bit choked up. I was having to rev it and slip the clutch a bit. It was ticking over ok and running ok on the open road but was was stuttering as you put the revs on. Is that thing normal with 400 fours?

That's what my brother said. He's just rebuilt a Kawasaki kh250 and I was supposed to be the clever one!!
Before I consider stripping the engine down would burning a bit of oil cause that much of a performance drop - depends how bad I suppose? Wonder whether that roar at about 5,000rpm is normal and whether it could be to do with fuel or timing or something else. Never having ridden a 400 four before I'm not exactly sure what to expect.
I suppose the Haynes manual isn't up to the job. Seems to be bits missing in it!!

I was going to ask if it's much of a job to replace a front fork seal for a novice to do on his own but now I think I may have a bigger problem.
I noticed the other day when I got stuck in the wrong lane on a ring road that I couldn't get the bike to go over 55mph to overtake and pull in. I've never tried before since I got the bike a year ago.
Been out on it today and same thing. About 5,000rpm the engine seems to get louder, and that's it it runs out of steam and won't rev any higher in the upper gears, so I'm stuck at about 55mph. Later on I noticed at these higher revs there was a trail of blue smoke behind me. Could it be this that's causing my problems? Piston rings or something? I've never ridden a 400 4 before but I thought in its heyday it was good for 90mph+, so I'm a bit puzzled as to what's wrong. Up to 55mph it seems to run ok.
If it's something to do with the engine do you think a novice like myself could tackle it?
Thanks

Well it is a left-hand drive Italian model so may be that explains it.  Thanks for all your help. I'll go and have a closer look now. Shaun

Don't know what I've done now but I decided to have a go at adjusting the idle screw before I went out for a ride this afternoon. I had a quick look in my Haynes manual for anything that looked like an idle screw but couldn't find anything. I had a look at the right hand carburettor and saw a black plastic adjuster and something in a similar position on the inside carburettor but metal. Confident these were the idle screws I started to turn the outside one out by half a turn. Unfortunately, I didn't get to unscrew it half a turn before it stopped. I then noticed that this black cap had a little thing on it to stop it being turned too far. Panicking I tried to turn it back to where I thought it came from.
I don't what it was I adjusted but it seems to have made the bike slightly better at picking up when the throttle's closed. Do you think it is it the idle screw I've adjusted and how come I can't unscrew it any more?
Thanks

Hi K2-K6
That sounds like it. I think they said it was running a bit rich and adjusted it. This tallies with what my brother was saying about different jets in the carburettor. He was wondering whether they'd got blocked and wanted me to take them apart and clean them. But yes as soon as it gets over its little stutter the engine flies along. One question though is how do I know if the mixture is right? Do I have to take the spark plugs out and check them or just see if the engine is running right? Sounds simple if I can get it right!!!
Thanks
Shaun

Thanks Florence. Think I will try and stick to my original seat as long as I can. You're right I think there's more character than in a new one. I had tried superglue and a strip of vinyl underneath to try and stop the padding showing through and it's lasted for 9 months. I just wondered if there was any more permanent fix.
Regarding the engine it's not major, just a little annoying. I may look into it some time when I feel up to it, but I haven't really got a clue what I'm doing.

Just got this 400 4 at Christmas and took it to a motorcycle dealers just to check it out. They said it was running a bit rich and adjusted something. Anyway since it's come back the engine seems to stutter as you rev it. Once the revs are on it really runs well. It just makes it a little difficult starting off as I have to have a few revs on slip the clutch a bit more. Also going round roundabouts when you shut the revs off and want to put them back on again. Any thoughts what it could be? Is it a normal Honda 400 thing? Wondered whether it was something I could tinker with but I'm a bit of a novice.
Also, does anybody have any thoughts on repairing the bike seat? Mine has a split along it. It seems to be an original one with studs etc. I know I can get it replaced but I'd rather keep this original slightly well-worn one if possible.
