    Nope. And right now it won't move even when the other pistons are moving fine. I can maybe find a way to hold the others down, will that provide greater force to move that one?

    [Edit]. Went back out to the garage, wedged all 4 pistons, pumped the brakes until crooked one popped loose. Only problem is it really did pop loose and air now into the system and brake fluid ran out. :fpalm Now I gotta refix piston on seal and bleed brakes. Bleeding the brakes was exactly what I DIDN’T wanna do when I started this job but my monkey wrench always prevails in the garage. :D At least I’m in a better spot now than I was earlier when I didn’t know WHAT to do :thumbup Thanks to wcohl for suggesting of wedging the other pistons to get that one to move.

    With 4 smaller brake pads per caliper, one for each piston, you can hold down two of the pistons by installing two pads with a spacer between them. The spacer thickness should be slightly thicker than the brake rotor. With 2 piston calipers, a C clamp works to hold down a piston. With 4 pistons, you will have to be more inventive.

    My concern is if the crooked piston comes out any further, it might come out completely. If this happens, you may have to split the caliper to reinstall.

    Yup. See edited post above. I’ve popped the pistons loose before and didn’t have to split caliper to reinstall, just seemingly had to bleed brakes cause in the system. In the past they seemed to work fine after reinstalling the pistons but again, I did have to bleed the brakes to get everything working again.

    BTDT. Brake bleeding is a relatively simple job, but is one I never look forward to. No matter how careful I am, my hands smell like brake fluid for the next few days.

    Yeah, I mean at least I’ve bled the brakes many times before and know how to do that per se versus being in a state of confusion earlier as to how to get the one to move. Oh well, I feel like over the years I’ve learned a great deal as per mechanical things with bikes and have accomplished many mechanic jobs I never dreamed I could; yet, it never ceases to amaze me and often frustrates me that I have to learn in the garage mainly from my own mistakes. I’d like to take the short road to enlightenment every now and then :lol3

    Had a great ride today :D I think Ive found the perfect bike for me. Tight mountain twisties, followed by 25mi of dirt road, and finished off with 80mph sweepers through the mountain pass on the way back. Hard not to love a bike that can do it all! :super Wish I had more pics but you know how it goes when youre having a good time.

    West Camino Cielo. On one side, the Pacific Ocean:

    And on the other, Lake Cachuma:

    The road follows this ridge line From SB up the Gaviota Coast, then drops either into Refugio State beach, or Santa Ynez, depending on which way you turn:

    And the obligatory glamour shot :D:

    It was my first time doing any sort of dirt riding and I had a blast! Definitely going to continue looking into some 80/20 tires. Anyone here ridden Shinko 705s? I know the rear doesnt come in the right size but they still caught my eye.

    next time, with the caliper off the disc, leave the pads in and only pump them out til the pads touch, that as far as you need to clean. it will go back in if you push on the high side with some force. couldnt say if the seal would be damaged. might have to split the caliper

    Well it turns out I didn’t make it out as clean as I thought :doh Went out to the garage this morning and I’ve got a flat rear tire. Looks like I’ll be getting new tires earlier than I thought haha. In the meantime, anything I can do? I gave the tire a quick once over and didn’t find anything stuck in it. The rim is also ok. How can I tell if this is a patchable situation?

    You could try pumping up the tyre and slowly work your way around wetting it down with water with some washing liquid detergent in it. The detergent should highlight any holes, also might be worth wetting down your valve to see if that is the issue.
    Good luck.

    Just slammed 18.012 litres in the tank. I was 50km into reserve and knew I was pushing it.

    That 18l took me 250km which works out to 7.2 l/100km.

    For those of you who have put a man on the moon, that's 32.7 mpg.

    I get 45mpg (imperial gallons) day in day out but on a long run cruising at 75mph all day I’ve had 55mpg and 195 miles out of the tank with some to spare. No idea how some of you guys are getting such low figures?

    7.2l/100km works out to 39 mpg imperial. This is mixed city highway riding, with lots of squirming through traffic. 75mph highway riding would be substantially better.

    My fuel economy suffered by about 15% when I installed the Sporting Wood air filter and jet kit.

    Nobody is really asking for this but I’m gonna update this here. I put everything back together and, of course, had a ton of air in the line. I tried the overnight zip tie method and it didn’t work. I bled lines at all bleeders and things seemed “almost” back to normal and brakes worked but I could still feel a little more play in the lever when I pulled. I zip tied it again overnight and this morning back to 100 percent.

    Alright so my new tires showed up today (Shinko 705s). I thought I would be real smart and install the 16t sprocket while the rear wheel is off so that Id have all the chain slack in the world to work with... But it looks like I might need to have the wheel on to give the sprocket nut something to turn against? Ive read a couple posts about front sprocket swaps and one mentioned using the stock tool kit tool kind of wedged in the frame/sprocket nut and then using the rear wheel as a kind of make shift impact driver so to speak. Anyone tried this?
