Do I need anything special to replace the intake O-rings? Just remove the two nuts on each intake, lift, replace O-ring, and retighten?
Any comments appreciated.
Thanks

When the intake runners are out is a great time to reach
back in there and search for rotted carb drain lines or
vacuum lines...

Remove the choke cable cover. Loosen the clamp at the top of the intake runner. Remove bolts and gently pull out a the bottom, being careful to not damage the vacuum lines on #3-4 and 6.

No need to remove the choke cable covers. To remove an intake, remove the two mounting bolts loosen the clamp screw just at the top of the intake. Now using upward force like you are trying to push the intake farther into the rubber mount, rotate the bottom of the intake towards you and its out ...... do one at a time and make sure you use some rtv (or similar) just a dab to hold the new o-ring in place while you install in reverse order. |

To help make it easier to reinstall the runners, just spray some regular rubbing alcohol on the rubber and it slips in a lot easier.

It would be a good time to polish the intakes at this maintence interval.  |

Iv'e heard pros & cons to regarding polishing the intakes.
1) By leaving the casting orange peel inside the intake, it helps to break up the air allowing it to better atomize with the fuel.
2) By polishing the orage peel smooth, it allows the air to move smoother and faster into the combustion chamber.
I am by no means any kind of certified mechanic. Only self taught by necessity (and the Valk owners manual).
So, feedback regarding polishing the intakes will be greatly appreciated as I will be re-jetting the carbs, replacing the intake o-rings and replacing the vacuum & fuel lines in the near future.
Thanks in advance for all feed back.

I'm with you on this one Chris...I just replaced mine exactly like you described 2 weeks ago and no need at all to remove the choke cable cover Remove the choke cable cover. Loosen the clamp at the top of the intake runner. Remove bolts and gently pull out a the bottom, being careful to not damage the vacuum lines on #3-4 and 6.

There have been a few reports over the years regarding polishing the intakes.
The net effect, as reported, is no noticeable gains.

I just did mine as 2 had slight seepage. about an hour for the 6.
used a dab of silicone grease to hold o-ring in place and what was left on
my fingers went to the nipple in back and the top; made reinstall a breeze.
no time for a test ride, had to catch happy hour at the brew-pub.....
better start and better response off idle....

What is that big screwdriver doing in there? That can seriously damage the engine block. Don't do it that way. just loosen the clamp, remove the two bolts and lift the intake. If you want to make the job a breeze (even more) remove all six of the intake bolts on one side at the same time. You will be able to gain more room when you lift the intake. Still change them one at a time. |

Perhaps not ideal, but was the only way I found that would lift all the 3 intakes for me to work comfortably.

I've done mine at the same time as the air filter a couple of times.
When you're all the way down to the airbox anyway, you can loosen
the several airbox screws that hold the airbox solid to the frame. Then
you can remove all the lower intake runner bolts. Then the whole
airbox/intake-runner assembly is "free floating" there, easy to remove
a runner and change out the O-ring, one at a time...

Why do you need to lift all three runners? grab one lift it and rotate it out, change the O-ring and stick it back in the rubber sleeve lift and install. Repeat X5 Keep dangerous weapons away from sensitive FLAT mating surfaces.............are gloves needed for this, really? |
