Are those that crap composite pistons, throw them away and get someone to turn you out some stainless. Seeing them on cars going out of shape and sticking up causing over heating.

I have come to the conclusion that those marks and the ring of dirt have come from the piston being extended under braking, that being the case they will only affect the dust seal and not the main brake fluid seal so they should be good to use. The local Brembo site only has bits for KTM fittings back to 2009 so mine aren't there.

Marcel, attention.

Super cool, Rich!

So here are the photos of the pistons and calipers, the little marks are baffling me as they have never been out before and they weren't dropped when I removed them. You can see a build up of matter around the pad ends but that scrapes off with a fingernail, maybe a light sand will sort them out, they aren't at a crititcal spot and the seals look OK so I think I'll reassemble them and see if they leak. I'll be doing the other side ones soon, the air gun I used didn't have a rubber sealing tip so I may try and use a rubber glove with a pinhole in it or something, until I get to see the condition of those pistons I'll bide my time.

Walked my dog today, had a good talk with my bro in the morning over breakfast, then rode my bike through heavy rains on twisty douro valley roads, met up with Sofia, fixed some englishman’s tire puncture on a GS, then rode some more, had a great time over a great dinner, and now setting in bed while rain pelts the window and bikes are safely parked in a dry garage.

Mine, today:

Pick which ever you prefer and post it again. I’ll consider the last one you do choose, tomorrow.

From a brilliant day @ Wallowa lake.... Got this one framed & on the living room wall.

Motus V4

Tried to pull the truck outta the carport this morning to finish filling the bed up w/ yard debris....battery was completely flat....put a meter on it to see how bad it was...Flat 00.0- dead as a door nail. Drove down to La Grande & scored a battery @ WalMart for $140...finished loading yard debris to take to the dump tomorrow morning. Tonight is date night....Tequila is on the agenda. Definitely Riding on Saturday...probably farther out on Clark Creek.

He'd jump at that shit for sure! But I find it so depressing that you go into bike showrooms these days and they're just full of Chinkies using a multitude of different brand names. The irony is they've done it by building the sort of bikes that people actually want......like in the under 500CC Adv/Trailie market. And the Japs have just let them do it because they've been on a mission to build the bikes that they think people should have. Which is the polar opposite of what people actually want.

The trail is badly washed out on the way up from the ford, the tarmac centre bit is almost gone and it's very loose. It made my starfish clench a few times

Oooooooooh look !! Phil's new bike .................

I was up on top of the hill in the distance in your photo, at the top there's a track going off to the right i went up there a short distance bloody midges everywhere until i lit the fire, that was 2012 fook me

Thats a damn good question!...lol At 1st I thought it might be a Life-Flight helicopter....but then it could be just a fly on the Google camera....lol That's a hill heading south outta Elgin that I drive @ least twice a week....it's known as "Hamburger Hill"...for the deer that like to cross near the top....seen a coupla close calls before as some folks (myself included) get going up to 70 mph to get by the Trucks...hence the passing lane.

I've just been searching for the model number of them, do you know how many calipers they make, effing hundreds and they all have tiny differences, nevertheless I have managed to get four of the pistons out from the passive side of the units and will be updating my tale soon. Cheers.

I remember when you took your son to camp there on your Africa Twin.

Yes, Pete, you've got to wonder why they need an oil change that frequently!
