J-WELDO Posted April 10, 2007 Report Posted April 10, 2007 Ok guys, got all my bugs worked out with the engine now when I drag or nail it it pops sound like tranny or a bad sproket but when I ride easy its ok after puting cub and crank it has only gotten worse.When I put my crank and cub on I took lower end to my local builder to have it look at ,he said 1st and second were wore pretty bad and forks looked great so I bought a used tranny on flea-bay and installed it same problem .Could it be a bad spline on axle and hub for the rear sprocket and it is pretty hard to shift too has anybody had the same probs? please help. my last post was pretty helpful 90percent of the replies sent me right to the problem.

okbeast Posted April 10, 2007 Report Posted April 10, 2007 Off topic-My grandma lives up in Thomas...small world On topic-Try looking at your sprocket/chain while you're riding it to see if it's skipping teeth. You should be able to rule that out easily. As for the hard shifting who put the tranny back together? Quote

O ya small world I have some family there last names are Unruh.I put the tranny in myself it was just a matter of putting new seals in and dropping it in,pretty easy Quote
J-WELDO Posted April 10, 2007 Author Report Posted April 10, 2007 How do you fix chain jumping sprocket, the chain is new and so is sprocket replaced all when I put 8 over swinger on ,come to mention it thats when I started having these problems when I put the swinger on. Quote
okbeast Posted April 10, 2007 Report Posted April 10, 2007 Hm, name doesn't sound familiar but I'm not from there so not many do. As for the chain jumping just make sure it's adjusted properly. I usually try to have about 1-1 1/2" of free play in it while not sitting on the bike. I'm not a very big guy either so I don't stiffen it out much. As for the splines between the axle and sprocket hub mine are completely worn out and my sprocket will rotate 1/4" freely and I still don't have chain slipping problems or any popping...hopefully someone else'll chime in.

J-WELDO Posted April 10, 2007 Author Report Posted April 10, 2007 Is it possible that the swingarm could cause this I picked bike up and swinger is loose ,maybey bad bearinings Shouldn't be though just put it on got it from Scott at cfm do these require a aftermarket bolt or what it shouldnt move that much and it's problaly causing the popping when I give it hell, making the chain try to jump Quote
wesw Posted April 12, 2007 Report Posted April 12, 2007 you might put your bike on like a atv lift or something and see if you can move the swinger side to side if it moves much at all you might have to shim it. also check the alignment of your chain with the sprockets. i had one that would pop and it rolled a chain off.

CFM Posted April 12, 2007 Report Posted April 12, 2007 (edited) Post up some pics, there should be no free play in the arm. The bearings are factory.. The stock pivot bolt and sleeve are used, should be a bolt in and go unit. Is the pivot bolt tight? Is the sleeve worn out? How did you install the needle bearings? If the chain is jumping teeth on the sprocket, I would assume it's a simple chain adjustment.. PM or give me a call if you are still having problems.
