There is a bit of slack in my driveline. I notice it during quick on/off throttle situations. What is the source of the slack? Can it be adjusted away? |

the front drive pulley has a cush drive built into it. basically big rubber cushins to soften things up when you bang gears and such. |

oh, and some people have shimmed it so there is no give in the cushions which helps it to have less slack... |

I need to try that trick Tim. There will still be slop due to the straight cut gears. The same feature that gives us such a smooth tranny contributes to more gear-lash(theory yet). I have a hard time believing the lash in Loretta's drive is solely the cush-drive. Don't mind wrong guesses too much, if somebody else tries it, be sure to post. details Were there any details from Sly when he shimmed his?? Zack |

How does one shim the front pulley? |

The drive pulley has a cush-drive inside. Slypirana shimmed his so the rubber cushions had no slack. He said he liked it but I don't remember if it eliminated the drive slack. I had a Firebolt, and it had ZERO drive slack. Loretta has... quite a bit.. yes I bit my tongue. Z |

T - Why....would there be more wear in the transmission (no "trannys" here!)? Even though they are directly connected, one has little to do with the other. No one's locking anything up, just removing some of the wear and or softness of the cush drive rubber cushions. Mike |

when i read this the first thing i thought of was when i was riding down the interstate in traffic, in and out of throttle due to traffic at about 55mph, i would get a delay in throttle as i twisted and then a small bump. it's a freebe and easy to do, double check your throttle cables. i took some of the slack out at the throttle control at the handle bar and that seemed to smooth it out a bunch. may not be what you are feeling but it is worth trying |

Have you denoided and tied the butterflys with safety wire? |

This is my 15 years and 95000 miles on a 96S1. Going from torque to big torque on a well tuned s1 starts at 2500, 3500 to 6500 is big torque. The CR starts at 4000, 4500 on big torque. My experience is that slack/clunking happens at lower RPM's in low torque (<4000 rpm) situations. Short shifting a little too short is happening less and less as time goes on. Clunking is the event that tells me to downshift. After a while you just downshift without the event. |
