the unknown binder Registered: 09/09/2009 Posts: 140	Have never ran cut tires but we used to have that problem. We increased pressure slowly until bounce went away. Effectively taking away unnecessary side wall flex. Reply Quote

Asking	Would adding more tire pressure take away traction to let tires spins easier? Reply Quote

Peter Rabit	Bouncing is caused by a few different things. would have to see a video to adress corectly. Driving, track conditions, weighting, and tire pressure are all posibilities or a combination of them. Reply Quote

Dairy blend Registered: 04/06/2008 Posts: 263	With bounce that early in the run it's most likely your clutch slipping and nothing your going to do with you tire psi will really fix that. What are you running for a clutch? Straight shaft or T/A? Reply Quote

Marshal	I would agree on clutch. What is the chance that the throw out bearing isn't allowing the clutch to fully engage? Reply Quote

Peter Rabit	Yep, definetly something going on in clutch. Once it bounced once and your foot is still on pedal, you are only making it worse cause your pushing the clutch back in at every bounce. I'd try side stepping that prick once the chains tight and you've got boost. Reply Quote

keyboard puller	Just an observation, but that sled doesn't look like it takes off very easy from the line on that video, that's probably not helping your clutching/bouncing problem. Reply Quote

Dairy blend Registered: 04/06/2008 Posts: 263	A 2 disk clutch isn't going to hold if your making the power you should with that setup. And just cuz you don't shift your TA doesn't mean that it's not going to slip. Been there broke that... Reply Quote

bc35 Registered: 01/19/2010 Posts: 105	About all a 2 disk is good for anymore is farmstock, anything hotter you won't get much life out of it. I'll say it is your clutch too, what disks are you running, buttons or Crower (sintered iron)? Depending on your 2 disk from Atlas you may be able to add a 3rd disk to it, call Karl and see what he can do for you. Reply Quote

Clutch	Check your clutch plate for warpage bet that's the culprit? Slipping clutch makes it worse. Reply Quote
