Damage prone part that is in this instance, cheaper to replace than refurbish!

These super little Honda's were groundbreaking when launched in the early (350) and mid (400) 'Seventies. As a classic they are as revered as much as any Honda from this or any other period. When re-building or restoring one of these delightful little multi's, you probably would not consider using anything other than genuine Honda parts? Good decision, make sure you use genuine Honda gaskets as well, and leave old British bikes to maintain their reputation for oil leaks!

Before placing your order for this oil spring seat, take a few moments to browse our online catalogue for your model, or where possible, try our online 'part list' fiche. You may find other consumables or parts you may need to complete your service or overhaul.

If your filter bolt is worn or suffered damage at the hands of a previous ham fisted owner, it would be easier and safer to replace this important engine lubrication component with a new part.
Before ordering why not check the online parts catalogue for your motorcycle? You may find more parts you need for your general service or a ground up restoration.
Please check the model application list carefully to ensure you specify the correct part numbers for your machine

Oil lubricates and also helps cool the engine - it can only do this when the oil pump is in tip-top condition! Renewing as many of the wear components as possible, including this VALVE RELIEF SPRING will ensure the efficient operation of the pump will not be compromised.

Dropping in to top gear, revs rising yet you are not going ant quicker - sounds like a clutch overhaul is called for!
Buying genuine Honda clutch plates will mean years of good service, and if ridden with some mechanical sympathy, perhaps a lifetimes service!

If you are considering overhauling your clutch, and replacing the friction discs, you might check out the plates as well, as they wear and distort through years of use and perhaps abuse at the hands of a previous owner!
To assemble a comprehensive shopping list of must have clutch parts, take a look at our online catalogue, or where applicable the online 'parts list' fiche. This will show everything you need down to the last clutch spring!

Replacing the CLUTCH LIFTER PLATE should be part of an overall strategy - renewal of the fasteners, seals and gaskets is also advisable.

Enjoy the feeling of a nice balanced clutch operation on your classic Honda, by spending very little on a new return spring!
For other low cost items that will improve the feel of your favorite bike, take a look at the online catalogue or where applicable the online 'parts list' fiche for your model.

Signs of clutch slip, no matter how small, even if your clutch cable free-play is adjusted correctly, will only become worse! You might as well take the plunge and overhaul your clutch, using a new Honda CLUTCH SHAFT as part of an overall clutch parts replacement strategy.

We are delighted to ship as much or as little as your order stipulates, but the more comprehensive your order the better value our already competitive shipping charges become!
So before placing your order for this replacement ADJUSTER BOLT, check out the 'Gallery' view of parts and the schematic for your model (where available) and obtain even better value!

At a low price like this, for such a high quality component, it really is not worth trying to rejuvenate the original!

Just like the friction disc, the clutch plates wear and distort with years of constant use and abuse (!). So if your beloved classic has a clutch that is stiff to operate, has a wooden feel, and generally spoils your riding pleasure, perhaps an overhaul will sort out the problem.
Take a look at the online catalogue for your model, this will help you put together your 'shopping list' of all the items you will need, including plates, friction discs, clutch springs, gaskets and seals, maybe even a new cable to ensure smooth operation.

Ensure your Classic CB Four receives its ignition spark at the correct moment, by fitting a new genuine Honda contact breaker assembly. If you are still running the original assembly, it's importantly close fit, will by now be a little loose, affecting the ignition timing, and giving generally lower performance than it should.
Don't forget you will need the other contact breaker assembly -300-154 as well, if you wish to renew the complete system.
To ensure you have all the parts you need for a satisfactory conclusion to the work in hand, check out the online catalogue, or where applicable the online 'parts list' fiche for your model.

Few ignition parts will do more for a perfectly timed spark than a new set of contact breaker points-Especially when fitted in conjunction with a new condenser, spark plugs and new ignition coils where available?
Other ignition related parts you may wish to consider including the Left contact breaker:

30204333004
30250333004
00000KIT0001
30520333013
30510333013

If you could only choose one new ignition component to replace it would be the contact breakers!

Renewing this important lubrication aid to ensure smooth contact breaker action should be carried out inline with the suggested service schedule. At least once a year if you are not sure?

Replace regularly to ensure smooth contact breaker action!

The condenser serves two purposes, one to act as a reservoir of power to feed back to the primary side of the ignition coil, when then the points are open. At the same time absorb some of the coil output to stop the points arcing across, burning them out more quickly than would otherwise be expected.
Renewing the condenser is highly recommended when renewing the ignition points. To check out the other ignition consumables and parts why not browse the online catalogue and 'parts list' fiche for your classic CB Four?

Removing and replacing the points cover during necessary maintenance work, will lead to the gasket failing to seal the points from the vagaries of the weather. We would advise a couple of these gaskets stored in your garage, will ensure this does not happen, along with miss-firing, or even total ignition failure!
For other useful and important seals and gaskets, try browsing the online 'parts list ' fiche for your classic CB Four.
