B86_Racer Posted December 18, 2004 I just bought a DID X-Ring chain and was wondering if that fastway spacer is required for the chain not to rub the case?? Please advise. Thanks! Share this post Link to post Share on other sites
400EXMikey Posted December 18, 2004 I bought one with my RK X-Ring chain. It is like $3.00. Share this post Link to post Share on other sites
B86_Racer Posted December 19, 2004 well i've got one ordered but it's on backorder for who knows how long. so i guess the consensus is that you need some kind of shim/spacer? Share this post Link to post Share on other sites

fastwoodsracer Posted December 19, 2004 I use a 60 thousands Valve shim from the local auto supply,They gave it to me. I used it on my 02, and now on my 05. However, toss the 2 piece countershaft tighteners and use the 04 setup. The solid piece will break, leaving you with the outer ring sounding like bells on a sleigh.

B86_Racer Posted December 19, 2004 Ok so a valve shim for my YZ250F is a solid piece, how would that work as a spacer? pictures? Thanks Share this post Link to post Share on other sites
huffa Posted December 19, 2004 It wouldn't. Here is the fastway. A 1.60 http://www.fastwayperformance.com/_images/popups/bikep_shaftspacer.jpg Share this post Link to post Share on other sites
B86_Racer Posted December 19, 2004 well, like I said before...I've already got one on order but it's back-ordered for who knows how long... Share this post Link to post Share on other sites
fastwoodsracer Posted December 19, 2004 ok, thats fair. the shim is for valve springs on an automotive engine. just pick one with the same inside diameter as the outside diameter as your countershaft sprocket. its just basicaly a washer, but valve shim stock for valves on a car is harder than plain stamped steel of a washer. it should be copper in color for 60 thsds, and silver in a 30 thsds. I got mine from a car quest auto parts store.here's just what you need this is the 30thsds, but diameters are right Share this post Link to post Share on other sites
fastwoodsracer Posted December 19, 2004 and to answer the real question,,if you use an O-ring, YES spacer it Share this post Link to post Share on other sites
Redlines Posted December 19, 2004 So if you use a high quality non o-ring chain like the RK gold you don't need to run a spacer and its not gonna rub the case on a 05 450F? Will the non o-ring chain have more side to side flex than the o-ring? Share this post Link to post Share on other sites
B86_Racer Posted December 19, 2004 FYI, I just went ahead and ordered one from rocky mountain MC last night. It said they had them in stock so hopefully it will be here next week. Share this post Link to post Share on other sites
yogist Posted December 19, 2004 I want to run a 12 tooth countershaft sprocket on an older cr.. Lowering the gearing for tight rough singletracking..The chain rubs the case when I put the 12 tooth on..If i use this spacer, say .060...Do I need to shim the rear sprocket also?? Or over the lenghth of the chain willl the .060 shim not be a factor..I didnt want to bind the chain or anything like that.. Share this post Link to post Share on other sites
Strick Posted December 20, 2004 I am using one on my '04. Share this post Link to post Share on other sites
ibfurloughed Posted December 20, 2004 I'm using one also with a DID x-ring. People here in the past have said you can "flip" the sprocket and that will give the clearance you need. I never tried it though. Share this post Link to post Share on other sites
Lackey-92 Posted December 20, 2004 Hey Donavan, Use a chevy small block value spring shim. Ask your dad or Jeff. Don Share this post Link to post Share on other sites
fastwoodsracer Posted December 20, 2004 Flipping the sprocket looked like way to much of a change,I'd bet it wears the sprocket and chain out prematurely and also cause other alignment problems. Share this post Link to post Share on other sites
