Yes pretty much unfortunately mate, this forum's pretty well dead nowadays. There is a couple of others that sometimes log in/post, but very rarely. Tony is on here every now and then, but mostly it's just me, and now you too haha

I'm not sure about option 2, would you move the lower A arm mounts out too? Either way I think you could run into problems with the suspension geometry being out, or reduced travel, or shock mounting angle being incorrect? And as you said, that wouldn't be easy either.

I can't really help with the shocks sorry mate.

You said you didn't want to cut/weld if it can be avoided, but another idea, (less work, but maybe not as good/strong?) is to notch out the hip frame where the arm hits it, allowing it to travel the full distance, but without having to do "extensive" chassis modifications like my other suggestion lol

If you did this, you would obviously have to add a couple extra bars in to brace it, and I think it you would end up attaching the A arms mount onto the notch.

I don't really have any other ideas sorry. Do you have Facebook? If so, join the EDGE Australia page and try asking there, there is more active members on there nowadays.

Hey thx corey,
I haven't see page 2, so I've changed my last post.

Yes you right, the geometry could be changed. The Distance between the two holes is unchanged. The Other way cold be to change the distance and move out the hole parallel to the ground.
I'll try the travel movement when the shocks arrives then I can cut out everything and burn it down in the woods. :lol:

Yes I get the facebook updates. but the forum is better I think. I dislike facebook.

Next Question:
On the 1st image you can see the upper A-arm connected centre of an imagined point at the baseframe. (I marked it with the two green lines)
If I spin out the rod end the A-Arm gets wider and the rod end isnt in centre anymore. (2nd pic)

Image
Image

I have seen coreys changes but can't imagine, that nowbody uses the spin out function. Or is there anything I havn't seen?

That's alright mate, just thought I'd mention it just incase!

That adjuster nut has two adjustments: one is the rod end obviously, and the other bit is for the castor angle.
The castor angle changes something to do with the steering, I think winding it one way will make it turn in better, but it will have heavier steering; and the other way reduces the turn in, but will make the steering lighter. (Just off the top of my head, I think that's correct... lol)

With the rod end spacers in there, when you wind the adjuster out, the top of the upright will move back or forth, instead of the rod end moving in the mount.

Although after writing that and looking at the pictures again, I'm unsure if I'm correct.

Once you have the rod end spacers in it might make a difference, but it would pay to just triple check all your measurements etc, and if they are correct, it could just be because the rest of the suspension isn't connected, that it looks incorrect.

My arms I don't think change anything, the dimensions are all the same still, but I have thought about making standard ones anyway.... but I probably don't have to. We'll see.

I hope some of that made sense mate, after all that rambling, I think as long as all the dimensions are correct, it will all work out.

-Corey

EDIT: Sorry mate, I didn't look at the first page and see your change to the A arm mount. Was this issue with the rod end moving after you moved the hole centre 25mm?

Hi Corey,

Thx for your intensive Replays.

Uuuuupdates!! :-)
This Photo shows the A-arm problem when moving out the upper hole. So I escalatet at Friday:
Image

I cutted all out and resized it, now its unique. Radical, but the result is very good.
Image
Image
Image

I've welded all together and extended the A-arm-mounts again to reach the hip frame

Today I machined out the rear upper A-arm rod end adjuster:
Image

And the lower front A-arm connection tubes:
Image

The A-arm mounts are correct now and the problem with the rod end movement is still present.
I've also tryed out to move one rod out and the other in, but no changes. I will try again after the lower front A-arm is connected.

Corey:
I've seen your A-arm and asket my why you changed the design?

Don't expect those rod ends to last.
Bronze lined rod ends have not impact resistance & the bronze liner distorts & expands quickly.
Then the ball becomes loose.

Thx Tony,
That sounds not good. But he better rods are 4x more expensive then this. Maybe they are stronger but is the lifetime really 4x longer?
If the balls get loosen first time, i willl think of the other ones.

Ihope It's Ok, to post you emal-answer:
Put the spacer on either side of the rod end.
You get up to 4 degrees caster adjustment.

Thanky for that. :P


!Updates!
Sunday:

Yesterday:

Today I'll weld in the rod end adapter in the lower rear A-arm.

Progress is looking good mate!

The only reason I changed the design of the top A arms was because I'm lazy hahah lol. Nah purely because it was easier to make, didn't have to try and bend any pipes or notch any tubes (I didn't enjoy doing either of those things lol....). So it was just easier for me!

So even though I made those ones, I do plan to make the proper ones one day, because I haven't really been happy with mine.

I think later on you'll be glad you chopped your frame and fixed it properly; I think there may have been a few headaches down the track otherwise!

Have you got an engine or anything organised?

Hi Corey,

Ok, so I will try to adjust the caster this way.
I watching everyday for an 1000cm³ ca 100hp Motorbike, but in the german winter in the middle of germany there are not much offers.
I live in a city with a population of 230.000, but there are only thousands of scooters.

The difficult axle parts I let machine out from a company in the town and I hope I will get the parts befor 2017.
The shocks are ordered but needs to be importet from USA.
The wheels should be my christmas present.
The rest of laserparts I'll also try to get this year. (ring gear, pedal boxes, fuel tank ...)

In next time I have a "money" Project;
In march 2016 I build a beer bike for 8 persons, I sold it for 1500€. Now a company asked me to build such bike again, so I need to brake the buggy Project for Building it.

Update!

Hey Update Time!

Cory your Right, while starting building the lower front A-arms i've seen it isnt so hard how it seems.
I've readin an other thread that the lower A-arms better made of 25NB pipe so..
Image
Image
Image

I needed a lot of time to fit it together perfectly, but I think the result is very good.
Today I try to make the two lower pipes (lower = 20NB)

If the lower A-arms are ready, there is nothing to do next time. Because there is no material left.
I still waiting for the laser parts, the machined parts and the shocks.

Looking good mate!

Any particular reason for using 25NB tube on the lower front A arms? Just for some more strength?

Hey Corey yes I've read, that the both lower A-arms better made of 25NB because of the forces they have to hold.
Unfortunately I read it after building the rear lower A-arm.
But I can weld in an "X" of 20NB pipe. I've seen it on an other build.

Last A-arm is ready: What to do next?

You sure do work quick mate hahah looking good!

Did you have any troubles using the laser cut shock mount plates? Mine were an absolute sh#t to get lined up correctly....

At this point it worked very fine, but I aligned the tubes to fit in the Shockmounts.

But every part with slot and key I have to plain first before fit together. So I needed a lot of time to bring the front whelplates together.
Thats due to the laserconfiguration but the parts where costless so it dont cares.

Today the rack and pinion arrives and I noticed, that I only can adjust it correctly after installing the seet.
Images following...

Today I ordered the wheels and rims as a complete set.
And the Motorbike Yamaha FJ 1200 unfortunately it is an air cooled engine. But it costs 430€ +170€ Shipping to me, so its ok.
Maybe I will install an oilcooler with radiator.

Thats for today. 8) :lol:

After 5 long days I'll update a little!

I set the front suspension together
Image
Image

I started prepairing the pedals (but I still wait for the housings)
Image

I machined out these adapters for the front upper and lower A-arms (on the right is the better one)
I produced it from steel, because I didn' found someone selling 6061 T6 Aluminium. I think about painting it. But when the rodend will hit the paintet peace it will look very bad after a while, but without painting it will rust.
Image
Image
Image

Merry Christmas! (to me)
You can first imagine how big it is, if u've seen it!!! 12" 26x9" & 26x11"
Image
Image
Image

The producer of the difficult laser Parts sends me this pic!
Image


Now I've took the buggy from the table to the ground to have space for the "money project". Therefore I also had to advance the money to buy the parts. (700€) So the December will verry hard-up.

Thats all for now, when the motorbike arrives I'll send new pics. :P

mr shockwave; your italian neighbors have a nasty habit of tearing apart bikes (as well as wrecking and crashing them). maybe instead of searching for engines in germany you should ask them and give them a visit :)
a lot of bike engines circulate around europe that comes out italy. and as last resort you may look a bulgaria but chances are slim you'll find legal ones :)

and if you still need more power and torque : there are a lot of sites like this. http://www.hayabusaracingpartsitaly.com/
you can even get an engine built from ground up collecting parts so you don't have to pay all at once.

and please don't underestimate the importance of rod ends. you don't want to be complaining about why your head and legs are on the wrong place (like a flip) when a suspension arm suddenly decides it wants to move to a another city :D
there's a reason why they're expensive and tony says so.

Hi kenrox,

Maybe you are right with the rode ends, but some experiences you have to make yourself. :P

I already baught a motorbike: Yamaha FJ 1200 in very good condition:
Image

Yesterday I took of the fuel tank and got around 20l fuel. So my car drives for free the next 2 weeks! :lol:
I really need to clean up, there is a huge chaos in the workshop.

I'm very fast with the other project so I hope to get it ready in january.
Thats the 1st version from march 2016...
