    Check what you can first before spending any money, on parts or oil.

    If it was the oil, would it cause clutch slip, not judder maybe?

    40k is not high for a wet clutch.

    Yeah my last biffer had done 70k on one clutch when I sold it. Already bought the oil but I can keep it for now. I'll check the slave, pushrod and put fresh fluid first. Cheers

    One more question before I have a look at the slave: is the gasket really necessary? I seem to remember last time it seemed a bit pointless and I didn't replace it.

    Is the gasket between the slave cylinder and the sprocket cover?
    If so, its probably not really necessary. You could make one.

    Hi, would you be so kind to link the manual that states this? I am trying to find this information but with no success, thanks!

    An oil thread  :062:

    Some good information there Crispy, just to expand on the Honda recommendation

    Honda recommend an engine oil that meets the JASO T903 standard MA with an API classification of SG or higher and a viscosity of 10W-30 and suggest 'Honda four stroke oil or equivalent. Honda also recommend the viscosity of the engine oil should be based on the average atmospheric temperatures in the riding area and gives the following as guidance

    5W-30 for temperatures from -15C to +30C
    10W-30 for temperatures from -10C to +30C
    10W-40 for temperatures from -5C to +40C

    With that in mind here in the UK my oil of choice is Motul 5000 10W-40 which is a semi synthetic 4-stroke motorcycle oil that meets JASO T 903 MA2 and API SG/SH/SJ/SL. My oil filter of choice is Hiflofiltro's Hiflo HF204. With Engine oil and filter changes as per the Honda service schedule of 8,000 miles or annually whichever comes first.

    I've never really understood the rational behind the annual oil change because its always been my understanding that engine oil has a service life of two years before the additives begin to breakdown. Obviously if your laying a motorcycle up for 4 or 5 months you may want to change the engine oil first to reduce the risk of any internal corrosion.

    I recently read a highly technical analysis of the relative virtues of oils for the biffer, (typically i cant find it now) and just as Others says, they recommended Motul 5000 10-40 over the 5100. I also use the HF204 filter basically because it tends to be what my local place stocks and ive never had a problem with oil or filter in 10 years.
