All righty then,

and first up Happy Christmas santa rendeer to all

So, to fit NEW fork stanchion's + seals

I think I have all the bit's req'd (I think)

I've seen the horror on Youtube (that guy in the USA) of seized fork yoke bolts, so fingers crossed I won't have to suffer that !!!

But also the Youtube K seal + oil change...seems straightforward enough

Anything I need to be wary / aware of ( ps I have done it in the past...just not recently


Thanks
Rod

I had to take the forks out of my K11LT for seal replacement and whole procedure is straight forward. The only issue I had was getting the ABS sensor out of the left leg. I can't remember why I wanted it out but it was SOLID! Give all the internals a good clean before reassembly as they'll be coated in nasty dark grey oil.
I put 15w oil in when I refilled them which made my front end steer better without excessive dive under heavy braking. Having lived with 15w oil for 12+ months it's occasionally a little harsh but worth it if you ride with some enthusiasm.

Good luck.

but hopefully it won't be too bad

all the best

O both my Ks the stanchions refused to come out.....it became necessary to remove the entire assembly as one and take it to machine shop to have it all pulled apart.

Mine came apart quite easily. I too had a problem getting the ABS sensor out.
I put 10w oil in mine, but then bought some 7.5 oil for the next change, which I haven't done yet.
Olaf couldn't get his out because of his small stature, he has problems lifting up spanners that are bigger than a 13mm. Smile Smile Smile Smile Smile

Hi Rod, I boughtthese. Good quality and price, p&p etc.

Just be careful to take the opportunity to clean all the old oil and crud out of the fork ( most of it seems to come from the bronze bushings. ) . For refilling I found it easiest to put the fork upside down in a vice and fill through the drain hole with a syringe from your local friendly Pharmacy/Vet etc. etc.

Finally lube the lip of the seal with some fork oil, silicone etc. and be very careful getting the bronze bushings back in past them. Can't remember if I used the tooth floss trick on this set but think I did.

Feel free to shout me on the mobile if you need a hand.
