    Is it possible to reverse bleed right into the MC ? ie so I see bubbles in the MC fluid ? ive never been able to push fluid anywhere past the top banjo on a MC. Upto the MC banjo OK, but into the the Master itself , nope. What am I doing wrong ?

    Certain Hondas can cause you fun with bleeding. Normally I don't have much issue with the front calipers... if you have an SMC, then hafta follow the instructions for that and the PCV. On a VFR with linked rear caliper, I have bled with the caliper hung high, then leave it there overnight. An old trick is to bungie the front lever to the bar overnight and the rear pedal down overnight. Air will go to the highest point (front reservoir). On the rear, a quick squirt next morning should do it if the bubble went to the caliper.

    Yea, ive tied the bar back many times on the Nissin fronts trying to get the last of the air out, to no avail. Rears I have no issue with, but the Nissin fronts are a nightmare.

    If starting empty, I'll usually just open the bleeder and let gravity get the MC primed, if that doesn't work, I loosen the banjo at the MC. If using SpeedBleeders, hafta suck it through. After primed, I'll switch to SpeedBleeders. Have had mixed success with vac bleeding. Some can be a pain, I get it.

    As you push the fluid in allow a little pressure, then pull the brake lever. Essentially you are over pressurising the system and using the brake lever to control. It takes only a little practice - you don’t need 50psi to move air bubbles and this is really used to get most out. Normal bleeding then works perfectly

    A little bit of progress yesterday, starting to looke like a bike again. Rad re-mounted, Wheels are back on and brakes are re mounted and ready to start bleeding, a few other wee bits too. Tied up on other winter prep today (snow tires on the truck and cars), so no bike action.

    Really pleased with how the swing-arm came up. Castrol Super-Clean with a wd40 chaser to stop any extra corrosion. looks like new.

    Fairing stay and top radiator are back on, new bar grips are on, and the front fender is back on.

    The new brake pads arrived today, so we'll get them in tomorrow. Wiring will all get re-connected tomorrow too, along with the coolant hoses.

    wont be long and I can fire it up. maybe next week

    I fished the other spare frame out of storage today too, ill get that one in for paint soon (it was primed in the summer at the same time the other one got done). When I get back to the Euro bike tranny work in December, im gonna switch the frame out too, the Grey powder coat finish on that one just isnt doing it for me, too textured.

    That would be the time to do it. It would always bug you.

    I just gently feathered the lever while my son pushed the fluid through with the syringe. lots of bubbles.

    A few more steps ahead. Rear inner fender is on, coolant tank, PCV tank, new fuel filter and a few other small bits. Ive been very thankful for having such a large spares collection for these bikes, I've been to the spares barn more times than I thought on this one.

    Carbs should go in this weekend all being well (carbs were done by "Billy's out back", and came with the bike shrink wrapped, they retail for pretty big money, so im glad I got them as part of the deal).

    Aside from that, just stuff like the rear fender subframe and tail light to go on and the airbox and exhaust. Hopefully no leaks anywhere and we'll get her up and running soon.

    Frame for VF1000R #1 will also go to paint tomorrow, so I should have that back for early November.
