Scooters and sidecars

Asking folks who have a sidecar attached to a scooter, did you change roller weights to get better acceleration? 

I have a 2005 burgman 400 and a spirit eagle sidecar.  When I had it on a 550 Suzuki,  I installed a smaller counter shaft sprocket to give better acceleration.  

Would lighter rollers have the same affect as a smaller sprocket?

Thanks, John
