differentstrokes Posted January 15, 2007 Report Posted January 15, 2007 I rode the shee for a little while today testing out my new irazrs and a couple times when I pinned the throttle and it stood up it would jerk like something was catching or bind for a split second. Checked my rear linkage and it was fine, then checked my chain and it was a little loose so I tightened it (will test it out tomorrow). The axle bearings are new and everything has just been greased in the rear suspension. I'm thinking maybe chain slack and it catches when the swingarm angle changes. Let me know if this sounds right or if I'm overlooking something. The shock is in really good shape too. Quote

Its about 1/2"-5/8" loose with no weight, and its like no slack with all the travel out. might have been to tight. try pusing down on the back to see if it tightens or loosens. Quote
yamahaD4L Posted January 15, 2007 Report Posted January 15, 2007 my chain tightedns as my suspention goes down. Its about 1/2"-5/8" loose with no weight, and its like no slack with all the travel out. might have been to tight. try pusing down on the back to see if it tightens or loosens. ive had that prob also. especially when you punch it on the asphalt or practice hole shots on the asphalt. i checked everything out like you and tightened my chain and this and that. i concluded that my tires were slipping and gripping. giving the effect that the chain was jumping or something to that effect. so it may not be how you got your shee setup it could be the fact that you just cant lay all the power the shee has on the ground. IMO dont think you have a prob with chain tension since youve tried a couple adjustments. Quote
bansheeseat$$ Posted January 15, 2007 Report Posted January 15, 2007 I ran into this problem once before.It turned out that the tensile strengh of the chain was to low for my power output.I went to a higher tensile strengh and never did it again. Quote
differentstrokes Posted January 15, 2007 Author Report Posted January 15, 2007 The tires grab really good in grass which was what I was on, so maybe I was getting some serious traction. I didn't really use much travel when it would do it, it would rare up and jerk when it launched. Maybe it was slipping and grabbing like you said. I'd just hate to throw a chain, now might be a good time for a case saver. :shoothead: Quote

Hey Kai, what do you think a good tensile strength would be? I think most decent chains are 8,000+? I was thinking about a gold x-ring or something along those lines. Quote
sheefreak Posted January 15, 2007 Report Posted January 15, 2007 I have seen worn cushions in the clutch basket do that as well. Sounds/feels like chain is skipping teeth on the sprocket. Quote
2003LimitedBanshee Posted January 15, 2007 Report Posted January 15, 2007 Have you looked at your rear sprocket recently? I had the same problem riding in the sand, when I would stab the throttle as it was picking the front up I would get kind of a clunk, possibly jerking type action like you are describing. Turns out my rear sprocket was getting short to this world, and the recent upgrades I had made started to wave the sprocket teeth over. I felt like a complete idiot because I maintain my bike meticulously and I don't know how I overlooked it. Changed out the rear sprocket and threw a DID X-Ring on and it worked wonderfully. Quote
differentstrokes Posted January 15, 2007 Author Report Posted January 15, 2007 The clutch cushions are fresh and I checked the sprockets, but I guess I'll check again. Quote
2003LimitedBanshee Posted January 15, 2007 Report Posted January 15, 2007 Depending on how loose your chain was that could have been the cause right there. I was surprised how quickly my sprocket snuck up on me. If your sprocket is not long for this world, or if your chain was that loose, my money is that you were feeling the chain jump. I originally thought mine was from sand in the chain because the first time I felt it was hillclimbing in the sand with some deeper ruts. But then when I felt it doing it on the flats when I would stab the throttle it made me look further. Quote

Yeah that would be a good area.I run a 9200 on my cub but you wont need that much.Just make sure you get sprockets at the same time as the chain. Quote
87sheerips Posted January 15, 2007 Report Posted January 15, 2007 Sorry, i didnt read all the posts, but it sounds to me like u need a new swinger pivot shaft or bearings. This was happening to me when I popped the clutch, and the swinger was moving, allowing the chain to loosen up and slip a little bit. Put a new pivot shaft in and it fixed it. Jack your bike up uner the motor, and try to wiggle your swinger side to side. it shoule be tight Quote

kubiac3 Posted January 16, 2007 Report Posted January 16, 2007 i 3rd the swing arm bearings. You will also feel it when you lock up your rear brakes. I think the bearing kit is like 65 from pivot works. Quote
