So I just pulled the trigger on a cruise control kit for my...bike.

The install looks pretty hairy linky 1, linky 2, linky 3, but I'm genuinely excited about giving it a shot.

This might be one of my sillier endeavors. Can't wait!

To make the cruise control operate more smoothly when going up and down hills and eliminate surging, it is desirable to add an extension vacuum canister to increase the vacuum capacity of the unit.

Sorry, I can't help myself. Whenever you decide to do this, let me know. That install looks... interesting!

there's a perfectly reasonable explanation for needing an external reservoir: no giant intake manifold.

my bonk has four individual intake runners and four separate throttle bodies. although it's a decent size, (1300cc) there just isn't enough space in the intake tract to store enough vacuum to pull a servo to hold the throttle cable at 80.

it looks like i'll be tapping all four cylinders' vacuum lines (with check valves) and using an external vacuum canister. jeez.

i know it sounds old-school and counter-intuitive compared to a completely electronic unit, but the vacuum system offers a bike many advantages. one of which being a smoother (softer?) speed control versus a completely electronic unit.

if you go uphill in a car with the cruise on... you'll typically get a violent throttle shift to make it uphill. violent throttle changes = very bad things on two wheels. especially if turning (read: leaned over).

like i said, it's a silly endeavor. but why the not? i really wouldn't mind relaxing my right hand grip on long trips.

Sounds like my kind of project.

But wouldn't most cruise situations be covered by a throttle lock?

nope. different throttle for uphill versus straight.

if only i could use a $10 throttle lock...

Ok... I realize that saying what I did should have been taken in a totally car kind of way... but in reality, I was comparing your "extension vacuum canister" to a penis pump...

PostiVac?

it's not my bag, baby.

When are you trying to do the install?
We are talking about a cruise control, right?

Probably not until after the holidays at a minimum.

I may wait until spring. I guess it will depend on how mild a winter we have. And yes, this is a cruise control install.
