So after working on the slave cyl on the clutch of my FZR1000, I went out for a ride, and again after not very far I got the clutch friction point come creeping back towards the bar. Back home! Removing the slave cyl and checking the master cyl & the line, I could find no leaks!
I assumed that maybe the interior of the clutch hose was porous, although there was no exterior indicator of it. Because the rubber line runs thru the aluminum beam frame member, I tied a ductile steel wire, the kind steelworkers use for tying rebar, to the end of the hose before I pulled it out, you could use some solid copper wire in maybe 12 ga. alternately. That is to make it easy to replace the new hose. So off the my friend Steve, at Under Pressure, in Dania Beach FL, the bike shop where my engine is undergoing rebuilding after its Bad Day at the Dyno. The dyno run that lunched my engine was not at his shop.
Anyway, he fabbed a new clutch line from bulk s.s. flex tubing. It was $65 o.t.d while-I-waited, and because I like to get that kinda service, a 'fin' for the beer kitty.
Back-home, when I got a chance to replace the line (today) I at-first thought I had it bled sufficiently, and was getting ready to take a test ride. But-the friction point for the clutch lever started to come-back towards the bar w/successive squeezes, and I could have sworn I had it fully-bled! I had used the backflush-syringe method instead of my Mityvac. Again I checked everywhere for leaks-none. I removed the slave cyl. & turned it upside-down, still hooked to the line, to help any possible trapped air 'migrate' into the hose so it could 'work-upwards' to the master cyl. Hook-up the syringe for another reverse-bleed, do that, and I left the slave bleeder nipple open while I squeezed the clutch lever. I was rewarded w/a good amount of fluid moving into the syringe, and since I had light pressure on the syringe plunger, I could feel the fluid promptly moving as the master cyl piston moved from the lever movement. No air bubbles into the syringe, so I put a bit of pressure on the syringe piston as I closed the slave bleeder.
The next squeeze of the lever was immediate 'far-from-the-bar' resistance, and it felt like it should for lever resistance against the clutch springs (individual as-opposed to the VMax diaphragm). Now I squeezed the &*^&%@## out of it repeatedly and so-far, it hasn't changed. I am in the middle of a ride to check on the function, and this time, it appears as though the clutch repair may finally have taken-hold. So, it was multiple things that needed to be done for maintenance and repair. And, the reverse-flush did OK. :biglaugh:
The place I stopped-in to check on things is my other friend Steve's shop, which is a big seller of bike tires, batteries, chain/sprockets, helmets, clothing, etc., Competition Cycle Center also in Dania Beach FL. compcyclecenter.com
And, while talking with my friend Enrique, who works there, I saw some Hap Jones std bore piston rings for a Yamaha RT-2 on the table where the computer terminal on which I am writing this is located. So, I scooped them-up and am soon to leave with my aftermarket n.o.s. piston rings for my dirtbike I bought new in 1972 and still have, and some delicious smoked fish dip Steve has delivered from a local small businessman. And my clutch adjustment hasn't changed! Sounds like a good day for these reasons.
Enrique also showed me a bike he bought for export, it was in Pensacola, a 1983 Venture Royale he bought wholesale for export to So. America. It's in perfect condition, fully-loaded and w/many accessories. With shipping to FL it cost <$1700. He sends an ISO container every ~8 weeks to So. America filled w/bikes, cars, trucks, whatever his contacts there want. He also just bought from MI an Arlen Ness Victory Vision, a 2009, it's #32 in the production run. It was dropped on the right side but $1K should buy the parts to fix it, he paid $7K.
Enrique does the internet sales for Competition Cycle on ebay Motors, under competitioncycle123. They post thousands of n.o.s. o.e.m. parts annually. Right now I have sitting in-front of me a box of rebuild kits for Red Wing shocks, the top eye & piston & shaft ass'y. complete. There are all-kinds of things like that in stock, they are continually acquiring failed businesses' inventories and posting this stuff.
OK, time to ride! :biglaugh:
