Thanks for being gentle with me Pete.
I can certainly see the virtue in sucking rather than blowing.
My air bleeder works pretty well when I'm doing the car but so far I haven't got round to adapting a cover for the front brake and clutch on the bike yet. I'll get round to it sooner or later.
I've got a clutch master cylinder repair kit to fit as soon as I get the time and I think that will require some assistance to bleed through judging by the problems others seem to have had with theirs.

 

Thanks for the replies. The standard length valves looked like the tip (nipple?) was pretty short. I looked at my stock valves under the cover on the bike. They're short too so I guess I'll go with the std. length. It's starting to warm up here so I might be on the road sooner than usual. I normally shoot for April 15

 

Isn't it just as easy to attach a piece of tubing to the bleed screw, set the other end into a catch can, make sure the reservoir is full, crack the bleed screw and just let fluid run through until no air comes? It is necessary to keep the reservoir full while doing so. I've been doing that for years now with no problems, and found it faster and less hassle than pump, close, release, open, pump, close . . . etc.

 

I have linked brakes (93 model) and nothing was easy about bleeding them. must have went through a gallon of brake fluid, 2 different brake master cylinder kits(it has 2 that operate the rear), teflon tape on the bleeder threads, and a mighty vac. And I still think i have a little air in the rear brake!!

 

Ah yes. Linked brakes. I haven't dealt with those yet. Maybe sometime in the future I'll have that opportunity. Right now there is no desire to move away from the '91 CBR.

 

I ordered the valves from Dennis Kirk. I should have them this Friday. On other bikes/cars I've used the Mighty Vac and always sucked air from around the hose-nipple interface. It's hard to tell if the air is coming frome the caliper or not. With the speed bleeders the only air, if any, in the discharge will be from the caliper. This will eliminate false signals of air in the line.
It's supposed to rain here all weekend. I'll probably be in the garage prepping the CBR.
