Honda-SOHC

Thanks Matthew. It makes me wonder what causes it and if one replaces with a new one, does it simply immediately break again and remain working fine and undiscovered until the next engine rebuild? Maybe the engine has worked out how to improve itself in use by creating this extra oil way... weird, eh?

Hello all,

I think I have discovered a strange fault inside my engine that doesn't appear to have affected performance in the three years I've been riding the bike (and no I didn't do it when dismantling the engine).

What do you think of the little tear in the drum(?) between the drive and timing chains (as shown in the square in the picture)? Any experts out there seen this sort of thing before? I could ignore it and rebuild or tap it back into place, or seek a replacement.

I think this is just further evidence of a hard life... I'm hoping to give this bike a clean and easy long retirement one day!

Ta, D.

Doh... it shows how adept I am at this blog chat malarkey! Ta for the reminder.

Hi all,

Rocker cover came off easily enough and the rockers out, etc. but I can't work out how to remove the tacho drive. I have removed the little circlip that I assumed would be the only thing holding it in place, but the blighter won't budge.

Should I just pull harder or is there a trick (or something I've forgotten to do)?

Ta, D.

Hi kent400,

Just bought their front mudguard ('fender' they call it). Not yet fitted and will be some months before I do, but looks good out of the box. Hopefully it won't rot before it meets the bike... if it does, I'll let you know!

Cheers, D.

Hi all,

Picture your CB 400 moneypit's speedometer... it has a little knob sticking out to reset your tripmeter. Well mine hasn't. Not any more. No indeed, since - in trying to gently remove it - the thing was resistant to every method of teasing out, apart from that one where it splinters into lots of small pieces accompanied by an expletive from your author. Hey ho.

It took with it the rather brittle rubber sheath, grommet, thingy that stops water entering the clock through the tripmeter shaft hole.

So, I'm now looking for a rubber grommet and maybe the gnarlled knob thing too (although I reckon I can get the knob from a 1970s hi fi or some such).

David Silver doesn't supply these parts except with a complete clock unit. I hope I don't have to go that far, having gone to all this trouble just to paint the damned black bodies!

Anyone out there got a spare grommet they fancy selling me or a tip (e.g. "it's tha same as on a 1995 Hoover washing machine Model X", or some such)?

Thank you fellow sufferers,

D.

Hi Kev, welcome and thanks for sharing the warm feelings of IOM. Drew.

Hi all,

In my limited experience of such matters, I routinely use rubber grease when installing new seals, etc. Is this adviseable for rebuilding my 400/4? I'm thinking specifically about the front fork leg seals.

Thank you,

D.
