home made link pro? ideas?
I was looking at some pics of a link pro, and its not that complex, so i was thinking about maybe trying to make one. anybody else try this?
Im thinking that i either want to make one or buy one so i can have 2 marked settings on the link, one for street, and one for drag and i would be able to leave the shock alone? am i right in assuming this is how it could work?
street setup being 4 over, unstrapped, swap in rim with "normal" street tire, regular sized sprocket. drag setup being 8-9 over, strapped, swap in wheel with shinko and huge ass sprocket
if i could leave the shock alone (adjusting a few clicks on compression or rebound is no big deal) and just put a few turns on a link pro, that would make things a lot easier, plus i wouldnt need to buy a "drag" spring...
am i making any sense?:P 
thx!

I assume you mean the shock linkage on a ZX-12. If so, the part you'd have the most success making in your home shop would be the pull rods (dog bones). I've made a bunch of those for various reasons. The important things are using the right material and getting accurate, round, slop-free mounting holes. If you don't have a mill, the use of a step drill will reduce the amount of chatter and out-of-round. SAE and metric step drills are available from McMaster-Carr. I'd drill slightly undersize and ream to fit. There are some setups that use Heim joints (ball joint rod ends) and turnbuckles, but those are kinda heavy and complicated with way more potential failure modes to consider than a metal plate with two holes in it. They are also much bulkier and in some applications can come in contact with exhaust systems and other bits.
If you have access to a kinematics analysis package, you may want to map things out first to make sure you're not going to have any surprises (e.g., digressive rates). If not, err on the side of caution and follow a rigorous testing schedule.

KZ:
i love to see your enthusiasm for so many different aspects!
Just don't lose focus on that motor, putting it back together "right" is a challenge.

The dog bones will not change the rate of the spring, which the link pro does. Dog bones only lower it, and the shock will still suck..........
link pro will not do the same or better than a purpose built shock, but it will do a ton better than a stocker. Put a link pro with a good shock, and you have an awesome set up........
That is what I use.

Do they make a pro-link for the zx14?
will the pro-link for zx12 fit the zx14?
