First you buy one of the Clymer or Haynes books. Read it.....you'll need clean fluid, 13,12,11,10mm wrenches at least....then the bleeder screw wrenches which are 8mm in most cases and sometimes smaller.

If you don't have a complete set of metirc wrenches you should be heasding to Sears....

it's about a seven on the 1-10 scale. A lot of people suggest bench bleeding the cylinder before installation. Unless you have help you'll need a pressure bleeder to do the calipers...

13mm wrench: for the MC to the body of the car
needle nose pliers, to pull the electrical connector(s) and pull/install the feed tubes

It's a fairly straightforward job, but it is a real bitch to get the feed lines seated into the new MC.

Loosen the reservoir retaining strap and you can slide the feed lines down a couple of inches. Also keep track of which line went where, if you reverse them they don't fit right.

Sometimes a flare wrench works much better than an open end on the brake line fittings.

And a 7mm wrench is a better fit than an 8mm wrench on the 7mm bleeders. The Cap'n

I just put a 23mm M/C on my 914-6 this past Saturday and am having problems seating the feed lines. Now I'm wondering if I screwed up and crossed the lines. Does anybody have a picture or know which line goes where. There is a left and right coming through the body under the gas tank. Does the left line (outer) go to the front or rear of the M/C? Also, is it easier to put the black rubber grommets on the lines and them insert into the M/C or try to put the lines into the grommets in the M/C? Any special tools you have used for this? Thanks.[i]java script:emoticon(':(', 'smid_2')

It's done, now I remember why I didn't want to change one of those again!

Any tips or tricks to share? Did you end up pushing the lines in the grommets or putting the grommets on the lines and then inserting?
