Interesting idea Mr 650. My first thought is the original lower shock mount is only 1 3/4 inches from the end so there is not much room for relocation. Rather than going for a movable block, why not weld one large bracket  with three different mounting holes drilled?  In the late seventies when Husqvarna was sticking with the lay down shock theory, they had multiple lower shock positions.
BTW how did Lotsbub extend his pulley? Did he cut a new countershaft?

You got that right. I love those wheels, especially the orange.

that motor got away - as did some fine progressive 440's while I was busy with thanksgiving - oh well family first toys second this time of year!

Ok  - Progressive springs are progressive.  Say a shock with 2inches of travel and is rated 90/130lb has a spring the takes 90lbs of pressure to compress the first inch and an additional 130lbs to compress the last/next inch.

I'm 180lbs (maybe a tad more after all that turkey!)- and have the 90/130lb 412-4232C shocks installed. So let's take the first number 90lbs and double it because we have 2 shocks that's 180lbs. So in theory my weight would compress the shocks 1 inch. This does not happen because the shocks are angled  - they only compress about 1/2 inch. So for you to get the same reaction from the shocks that I do and your 180+115 rider that's 295lb - let's round that up to 300lbs. So if we cut that in half - 150lbs - that is the load for each shock. But noway are you going to want 150lb springs they'd ride mighty stiff with just you on there - so in comes the 5 preload settings - each click adds load to the spring that makes the spring shorter - so for instance if you could add an inch of preload on the 90/130lb springs then the first inch (really the second inch because we already compressed it one inch with the preload) now takes 130lbs to compress - to finally get to what I would do with this much weight - is install the 412-4233C 115/155lb shocks and keep them on the 1st preload setting when by myself and add a couple of clicks or more until I did not bottom out when the extra 115lbs was with me. These are not going to give you as smooth a ride as the 90/130s when your by yourself but they should deal with the 300lb riders better and keep close to the stock bike stance.

Sorry - just read that you wanted 12.5 inch shocks - (after all those wonderful words!) since you have quit a lot more travel with a 12.5" something like the 412-4208c 105/150lb may do well - but remember - a 12.5" shock is going to lift - "jack up" the rearend quite a bit - say 3 inches at least - also you'll need to modify the belt guard as the steep angle causes it to rub the belt, and then you have the issue of find an up hill place to check the oil in order to get the sight glass level,,,,,

are you sure you want 12.5's?

Length wise I doubt that 11.5 would rub the belt guard but it looks like 12.5 does according to Savage_Rob and Babbalou I think. But it also was a minor mod to cut the top out where it rubs. If I calculate correct the 11.5 should give you about 1.25 inch of lift when measured from the cnter of the rear axle to the helment lock - see the bottom of this post

I'd bet the 412-4201C 115/155lb 11.5" would work if you want a bit of lift and carry 300lbs of riders - but like the 11" shocks - 90/130 would ride best solo - best is not the right word - softest without bottoming out.

Thanks! I will look for 11.5". Hopefully there will not be trouble with the belt and oil checks.
Thanks again.
