    Black and Decker special tool...

    Yet more finely crafted special tools.....

    Wot you find in old shocks.....splooge...

    Plan is get some new springs with a better spring rate than the teeth rattling 70's ones, new o ring and 10 Wt Spectro fork oil.....be more betterer than new. Then fit them to the R65 for less bounce to the ounce and slam to the gram.

    Good stuff John !

    Are there any specs for oil level and amount?

    80 mls, seems to be some discussion between 5 or 10 wt.....
    Got the van sorted......it was a blocked fuel filter.......grrrrrrr......but better than a stuffed turbo

    Got the seals from Ikon today and put them back together with a new set of springs same as the Commando.
    Added 85 mls of brand fork oil and closed them up.



    Should be interesting trialing them out on the R65 compared to the old BMW ones.

    I've been using 5WT Yamaha fork oil with anti foaming and seal swell agents and that has been working fine for me under road use.
    Been reading interesting stuff from our pal Mr Ohlins who swears that you should be bleeding all the air out of rear shocks because any air in them causes foaming. So the last lot of Koni's I did, I filled them up to overflowing with 5Wt and wound on the top seal caps with it spewing oil out. Messy...
    End result seemed the same as when I filled them up with 85cc which was about 10mm from the top. Have not noticed any fade in either the 85cc ones or the filled to the top ones. I would have thought that allowing air in them would allow for oil expansion when hot - but Mr Ohlins said fill 'er up and who am I to question one so Yoda-esk?
    Any modern quality oil replacement is going to make a positive difference to the spooge.

    For road use Konis are probably ok but they have very little compression damping as use harder springs to compensate.....Mr Ohlins told me that.

    They were a massive improvement over the Marzocchi on my Darmah, although I didn't know shit about spring rates and such back then

    Read Mr Taylors reply on the Classic Forum.
    its a bit like:
    Mr Avon telling me I need his race tyres,
    Mt Siebenrock telling me my engine needs better parts
    Mr Code telling me I need better skills
    I know all that but Huntly wasn't built in a day.....

    Huntly wasn't built in a day.....
    Looking at it I don't think it took much longer and they didn't use good materials

    Poor old Hunty, or by the amount of BMW's ther it should be renamed Hunly

    Good stuff Mr Volty. An inspiration for us wannabe do-it yourself types. Of course you could go the more exotic route with those $115 a pair shocks.

    Motu suggested a rigid rear end as a solution..... worked for 50 years.
