Hi all smile

I have just bought a bike, a Honda CB400 Superdream. It has been completely stripped, rebuilt and almost every part replaced, and also has covered a genuine 21'000 since 83 when first registered. The chap that has done this does one every 6 months and has for years, his work is expert so full faith in bike etc

However, I am finding sometimes if I pull the throttle back sharply the revs race slightly higher than the engine speed and the bike doesn't respond in accordance with the revs. Apparently it may just be a simple question of adjusting the clutch mechanism? (No idea why, someone just mentioned it).

It only happnes on sharp application of throttle. I have done the fornt brake on dip clutch test and the bike responds normally, so guess the clutch is fine. Also the seller said clutch is fine so am wondering what might be the cause?

Sounds like the clutch is slipping to me, or maybe the clutch cable needs adjusting,scratchchin either way, probably not too expensive to rectify.....

James, Why not ast on Biker Banter? If I was you I'd also try visordown.com and I'm sure there must be a community specifically for you bike out there.

It might also be worth getting your hands on a Haynes manual.

I've got an abba stand if you need to borrow it. You'll just need to get hold of a fitting kit specific to your bike.

Edited to add, I thought you said it was a CBR 400, not a CB 400.

Thanks Phil... Its a CB 400 N Superdream... CBR - must have mis typed or something.

I think the clutch cable just needs adjusting, but it is a question of getting a manual to find out how to do it. Ebay here I come...

No idea on this one I'm afraid, suggest taking it to the Honda shop in Witney...
They're pretty good at getting stuff sorted and reasonably priced to.

At the handle bar lever you should be ablt to move the lever slightly before it starts to move the cable.

Look at where the cable locates in the lever and passes through the clamp.
you should have about 4 or 5 mm gap between the clamp and lever before the lever at the other end of the starts to move IFKWIM.

If you have no slack in the cable adjust the cable to get the right gap.

If the cable is too tight, when the clutch get hot it will be too tight on the cable and not get the full clamping effect from the springs.

if the cable is OK it might be worth dropping the cover of the side of the motor to check the plates and that the ring of bolts have been tightened properly.

I had those bolts come loose on an old kawasaki and it made one hell of a mess of the cover,

Worth buying a Haynes manual!
