Taking apart Keihin "D" slide carbs

Taking apart Keihin "D" slide carbs

Hi all,

  Do the Keihin "D" slide carbs that come with the Polaris '00 700 Deluxe
come apart as easily as a round slide Mikuni carb? In other words is it as
easy as twisting off the cap and pulling the slide, needle jet, etc. up and
out of the carb? Or are these type more trouble?

  Looking at the service manual shows the process to be pretty simple.  But
while pulling upward on the cap there seemed to be more resistance then I
felt there should be.  I have only worked with the Mikuni round slide
versions so this may be normal.  Wanted to ask someone who has actually
changed their needle jets out.

Thanks for any help you can provide,

Tim

Twist off the cap, and pull the slide assembly out.  Pull up on the return
spring and compress it against the cap.  Sometimes the blue retaining cap
comes up with the spring, sometimes not.  If not, compress the spring and
grab the blue cap with a pair of needle nose.  Once the cap is out of way,
slide the throttle cable down and out of the grove.  A 6 mm socket will
remove the jet needle nut and the needle & circlip will be right under it.

Yes they are comparable. You have to make sure you pull the slides out
squarely as they bind more easily than the Mikuni round slides. The
only difference in changing needles is that you have to loosen the
retaining plug with the 6mm head in order to pull the needle out. I
find also that the cap tends to want to crossthread easily when you are
screwing it back on so be careful with that.
