Xr100 shock upgrades

I am toying with an idea on how to use a pit bike shock on an XR. Gonna have to make some new linkage pieces, but that won't be that hard.

^^ that JRI has preload and rebound? Better price than the Works. Still at this point too much $$$ for my cheap XR lol.

 

One more hour and I'm at Grattan.

 

where can i get it at this price?

thanks

 

Its says Ron Ayers so I would imagine www.ronayers.com

thank you

 

Here's a new option: https://www.vonkat.us/shop/100x-shock

 

And there is a guy as well making new links to get some ride height and travel https://z-m-www.facebook.com/RHMoto...R_y-P_ijWUsn4vqAzVgp1Tg6HYGAu6cGb7Km-S1&ifg=1

 

I read that this one will fit as well. Nothing fancy, but it's supposed to be a bit better than stock:

I've tried it... has a stiffer spring, but ZERO damping. You get what you pay for!

 

Good to know! Is it better than a sagged out stock shock from the previous century? Maybe better for off road than pavement?

 

It's not good for anything. The stock Showa shock only has damping on the rebound stroke, none on the compression stroke. This cheap Chinese shock has no damping in either direction, so it basically makes your bike a pogo stick... bad for pavement, worse for off-road. You can't even use the spring from it on the stock damper, as it doesn't fit.

Keep in mind that whoever is selling these on eBay bought them from China, paid for transportation to the USA, paid duties on them, as well as eBay and PayPal fees when they sell it... and still makes a profit. It's junk.

The Vonkat shock, however, is the real deal...

 

T-bolt has DNM shocks for the XR/CRF. I haven't used this one, but I have used DNM stuff on mountainbikes a few years ago. I actually was a retailer and service center for them for a while. Not bad. Really good quality for the dollar.

I drilled a hole in my stock shock and brazed a fitting on it so that I could change the oil weight. It wasn't perfect, but it did help a fair bit.

 

Your experience with DNM is much better than mine, then. Years ago I bought 2 new inverted downhill mountain bike forks direct from the factory, and both had wept oil into their boxes. Machining work looked good, but after just a few rides they were gushing oil better than Jed Clampett's well!

People I've talked to who have the DNM for XR/CRF100 have told me two things: that the shock is 3/8ths inch too long, and the 650 lb. spring is too light. To install it, it has to be compressed by 3/8ths (not a fun task), so when installed, the 3/8ths of travel stays in the body of the shock. Also, since the shock is too long, it tops out not inside the shock, but by the linkage colliding with the swingarm.

The BBR aftermarket spring is 975 lbs, the Vonkat is around 1000. The only way the 650 lb. DNM spring can be made to work is by dialing the 20-click compression to 19-20 clicks, and trust me, you don't want to use oil and a shim stack to compensate for a spring that's too light. Tends to make things on the inside go boom!

Another of my own observations is that a hose-connected reservoir probably shouldn't be connected to the moving (swingarm) side of the shock for wear considerations... just my thought.

 

Good to hear. I haven’t used DNM stuff in a long time. Sounds like the went downhill. It’s a shame, because the forks and shocks I was dealing with were decent quality back in the day. I rode one of their upside down style downhill forks for years without a single leak. It sucks to hear the quality tanked.
