Any suggestions would be great, especially a cheaper way to go about the rear suspension.
Define "cheaper". I've got about 100 pounds of TW shock experiments on my Burt Munro "sacrifice" shelf, all yielding varying results. If you're lighter or heavier or place different demands on the bike than the next guy his answer to the problem may not work for you. I like to mess with stuff like that but I consider it a huge part of what I get back from the hobby, and if it doesn't work out I'm willing to start all over. But in the end it's far from cheap.

I'm not sure what your weight and ultimate goals with the bike are, but the straight rate springs now being offered by ProCycle are theoretically a step in the right direction. I wouldn't give up all hope for the stock shock body until the results start trickling in

Most of the nasty "hit" and lack of control in the rear comes from the progressive spring on our shock.

Great name for your project.

I need something better for more offroad and hard trail riding. But I don't have too much money to spend on the shock/spring. Something more solid for sure

I got no dawg in this fight. I now have an extended swingarm and an entirely new set of rules. Was just a headsup that a Frankenshock could end up costing as much or more than the new spring when all's said and done, particularly if your first attempt doesn't quite get you where you want to be.

A lot of shock and spring combos have appeared on these pages over the years. Regardless of the shock body used the one thing that the most successful ones have in common is a straight rate spring, whether purchased new or pilfered from another (usually heavier) bike. Because you're on a budget that's probably where your greatest gains will be realized.

ProCycle has taken all the fun out of things by providing springs of a known spring rate, height and diameter. I was just suggesting that if you have the luxury of time to see how they're working out for others you could either pop for one of theirs or attempt to duplicate the results with pilfered springs.

Whatever spring you come up with it can later be adapted to a "better"(?) shock body, if you're into it.

Any chance to see some pics yet. Even if it's not finished yet. Get us something to get excited about.

This likely will not be going too quick at all. I'm recently added an outlaw racing yz250f shifter, and I'm very pleased with that. Pics I will try to get later this week maybe. I'm planning on buying a kx250 by next spring. We will see how it goes.

I'm still sitting on the red ProCycle spring (so to speak) that I bought back when they were first added to the TW page. I'm slowly but surely getting parts together for a DIY compressor tool (and hopefully it works). So I'm crossing my fingers I'll get it done within this next week or two. I believe it was you asking for my opinion once I get it on. I almost said effit and took it in to have it swapped, but that's my last $200 allotted to the bike spending for a little while, and I'm trying to keep it set aside and ready to throw at lizrdbrth on a moment's notice for a cooler ;)

Yep yep, it was me. I was just thinking about that!

I also was wondering how the new ProCycle springs will work out. In the mean time I am doing a little, sperminten. The TW 200 shock has three grooves that allow for a preload adjustment. Liz has mentioned that the minor change in spring preload is not much. So, I took it a bit further. Frist I set the wire ring on the groove that gave the most preload. In conjuction with that. I made a 1/4" spacer and put it between the spring and the bottom spring seat. This added about 3/8" of preload. On the street, I liked the results. On the rough stuff, it beat the hell out of me! It was just to stiff. Back to the shop. I have moved the wire ring back to the middle groove and kept the 1/4" spacer in place. 1/4" pre load. this gives me 1.9" of race sag. I will ride it this way on the Roundup Reroute Ride this weekend and report back. When you remove your shock, don't "misplace" the lower mount cushions!! Thanks again Brian.

As promised, reporting back on my shock spring preload spermint. I rode the Cow Mountain Roundup Reroute Ride with the the NorCal group on Saturday with the 1/4" preload as discribed before. For me, it is a keeper. There is some give and take however. On pavement it is very stable and a big improvement. Mild off road is still a bit stiff. Where it worked the best was on the rough stuff. I gave it a good test on water bars at different speeds. Not once did it bottom out, where as it would have bottomed out many times before. I am going to keep it at this setting. For reference, I am generally a slow rider and about 220. Smaller people that want to try this, just move the spring clip first, that may be enough. Bigger guys might be better served as I first had it set up. I hope this helps.

Finally have some pictures. Went to the trails Saturday.


Yz250f Outlaw racing shifter worked great!









Later that night we made up a headlight rock guard... mainly for looks :)




this lil supertrapp might be next....

I believe Harbor Freight sells compression tool(s) fairly cheap?.

They had (have) a few, but the cheaper McPhearson strut compressors they have, like the ones I rented from Auto Zone, won't fit between the coils like they should unless you put is some work/grindage on the compressor hooks, which then make them a little scary to work with. Same with the Single Action compressor they have - not sure if the hooks will fit, not sure of the hook fitment if they do, and $70.

Now that I got most of the drilling out of the way (such a pita with bad chuck/key and cheap hole saws), I just need to get off my arse and pull the shock off the bike to give this a go:

I just ordered a new headlight cowl sticker as I ruined mine during washing (it was already cracking). I also ordered Red spoke skins.
