Trying a 400 pound spring, just a guess. Penske will change them out until its right.

The shock did show up a couple weeks earlier than they quoted, but there's a few mistakes on so its going back to Penske tomorrow.

Ordered my brake lines this morning.


always something

Sad Mike they will put a longer hose on the shock if you want and 90s on the ends.

The shock is in the box ready to go back, it will get

1) a longer hose with 90's on the ends

2) 12 mm mounting eyelets like it was supposed to have

3) length adjustment and the overall length it was supposed to have

#1 was my fault

#2 and #3 probably the fault of calling the first day they were back in the building after the flood.

I pick up a few little odds and ends at the local machine shop tomorrow (those guys are going to be sad to see this project end) its just about done, paint and final assembly coming up.

Mike, before you mount the shock permanently, be sure to remove the spring and move the wheel throughout the travel and check that the swingarm doesn't hit anything.

The angle looks a bit steep and given the distance back from the CL of the wheel, you may be looking at a 500# spring. A lot of force on things.

Once I get the upper shock mount built it will be closer to 45 degrees.

Right now the first thing that hits is the tire hitting the steering arm.

be sure to check things full up and down at full left and full right

I've been following this project, seeing all the fun stuff I missed by buying a rig (the Bandito) already put together and sorted out by the experts (presumably). But I'm dreaming about my next rig already and wondering about how it all goes together.

So, to continue the shock discussion - what sort of considerations are there for selecting a spring rate? Formulas, rules of thumb, whatever? Just from looking at the pictures, several of you are commenting on what might be appropriate, so there's obviously something here which my untrained eyes and brain are not processing.

Big Grin Dar down here we call it guessing around Smile

Dar,

I asked Bruce at Penske about formulas for spring rates. He said whenever he's asked the engineers there about it they all get real busy doing other things.

So its like Ralph said, guessing followed by trial and error.

(Also If I value my time at a dollar an hour, you came out considerably cheaper with the Bandito.)

Mike

When it all comes down to it...after all the high tech talk and engineering stuff the answer to spring rates is going to be 'guessing around' as mentioned. There are so many variables invloved that to give a definitive answer may sound good but it will probably be followed with another good sounding answer as to why the spring rate shoudl be 'adjusted' after the first spring was installed. This can all be made to sound really official and high tech but truthfully it is all under the category of 'guessing around'. Uh..within reason of course Smile
Think about it. What variables are we talking about here? Swingarm type and length, position of shock on that swingarm, angle of shock, overall weight of rig, weight distribution of rig, road surfaces being ridden on, driving styles, does it have or not have a swaybar and so on. We can spend tons on fancy shocks that may allow us to talk about the shock we are running but is is the right one for our specific rig with all thinsg considered? With all of the options out there the initial answer , in truth, will probably be no.
Good starting point? Following the monkey see monkey do plan is not a bad one. It is however also important that one has confidence in the real world knowledge of the monkey he is following...LOL.

Hi Mike,
How about a picture of the whole thing?

That's the only part that's done, the rest still looks like the previous pictures.

The hope is still to have it ready for the Boone BMW rally in a couple weeks. Starting to feel like one of those Biker Build Off shows, big push to finish by some deadline. Just don't have all the yelling and screaming.

The local machine shop called and my parts there are ready to pick up on my way home, the others have been shipped, so except for the last minute, "Oops, forgot about ,,,,," I should be good.

Hi everyone Smile (Newby to this whole scene and a futureHPS owner).I have been very interested and inspired by this project and the whole site thinking about it.
Question
I just have one (of several) Questions to ask ,, what is the thinking behind the long swing arm? as opposed to the shorter types fitted to rigs like bmcsheehy's (top pictures by the way, very informative)
cheers
liam
