Delta,
thanks for this info.....I have the Haynes manual but wasn't able to find this info (just the minimum thickness). The plates vary in thickness from about 2.40mm to 2.60mm....I take your point though. I imagined that new plates would be at least 3mm. The springs are at their minimum (free) servicable level so I am going to replace those anyway.
It may just be the springs that I need - the clutch mechanism was at its maximum adjustment level. When the bike is in first gear with the clutch pulled in, the bike wants to move forward when I use the kick starter. Any further thoughts?

Hi all,
has anyone a recommendation for a brand of replacement clutch...Wemoto have a 'Gecko' and an 'ECB'. The ECB is £20 dearer. Having a good clutch action is important to me so I don't mind paying for the more expensive one if it is a superior clutch. I suppose at face value, if it's £20 dearer, then there must be a reason why. I wonder how much the original Honda kit is? anyone know? I only do about 1000 miles per year so it won't get heavy usage.
Just as an aside - the average width of the friction plates is 2.50mm. The manual states that 2.30mm is the minimum. Does anyone know what thickness the new plates would be? This is an academic question as I plan to replace the clutch anyway and will know the answer when I get the new clutch...but if anyone can give me some guidance on the brand of clutch, that would be immensely appreciated.

Ok, I get it - enough feedback to put me off the whole idea...........I'll wrestle the airbox back in tomorrow and get a new stock filter. Thanks to all contributors.

Well the fuel economy will not worry me as long as it is just slightly affected. The cost of the cones is not a concern either (£25). I think the power filters would really complement the bike aesthetically...I know the purist would say the bike was fine originally and probably re-coil at the thought of altering it but there is no accounting for taste.
I don't really relish the thought of fixing the old airbox back on as it is quite tight especially getting the rubbers in. My only real concern is the re-jetting and trying to establish the correct one to use - does anyone know how I can do this??

I'm surprised that fuel economy is adversely affected. I thought it would improve economy, if anything.
I got your email Les, good to hear from you. For some reason the email I sent back to you was returned to me. Anyway, the bike has to be re-registered etc after bringing up from Dublin. I'm in loughinisland, near Seaforde. Sure, we should arrange to meet some time - when I'm road legal.
I'm wondering now what to do about this air filter business. The cone filters were really just an aesthetic consideration.

Ewan,
That's interesting, I had trouble finding K&N's but I have an alternative which should work well. But I'm concerned about the fuel economy; is that because of the re-jetting? Surely not the more efficient filters? How did you establish exactly which jets are needed?

Hi everyone,
just signed up here today after getting a 1977 CB550k...just undertaking a bit of tune-up work and was interested to see on 'wemoto' that they had power cone air filters to replace the stock item. (Now, I am trying to keep this bike as original as possible and this is the only modification I intend to make). The filters do look good, the chrome I thought would complement the bike well. I recieved them promptly and after wrestling the air filter box out of the bike (you need to remove the battery holder unit to do this) which wasn't that easy I realised there is no way they would fit onto the carbs serving cylinders 1 and 4 without fouling the frame. Anyway, wemoto have agreed to refund me but did say that they have sold the same filters to others without any hassle, which I don't really believe. There are other filters available at various other places but I was wondering does anyone have any experience with fitting and using these. I presume I will have to re-jet to something bigger to keep the fuel/air ratio correct?
On another note, the teething problem I refer to above was a faulty fuel tap which wasn't working in the reserve position. I spent two days trying to work out why the bike was running very rough (spark, check - compression, check - petrol, check, or so I thought). The fuel tap was very tight and took a pair of pliers to move and it was my intention to overhaul this anyway but as a last resort I decided to drain the tank and put in fresh fuel just to eliminate the potential for the fuel to have lost some of its properties through sitting for a while. It was only then that I noticed that, in the reserve position, the fuel was not leaving the tank. Eureka moment for me and the end of a lot of frustration trying to get the bike to run....put some fuel in (and tap in full on position) and she ran sweet from the first kick. I wonder are there issues with these taps? seems unusual to me having had plenty of smaller Honda with similar tap. Anyway, they're not cheap to replace so it will have to come off to see if it can be fixed or else I'll just live with it and carry a small bottle of fuel in my now defunct and empty air box for emergencies...
Looking forward to reading this informative board. Hopefully I can contribute to the resolution of other users' issues and problems from my own experience.
