I'm about to build a big block minibike for 1/8 mile fun. I see some of the drag bikes are running tensioners and some are not. The bike should have a good bit of power from 3000-7500 on alcohol and I'll be running a 4 disk clutch and #35 gold on gold chain for now (hopefully it'll make some passes). I've looked at a high-end tension that looks like it'll work well or I might make my own if needed. I'd just like to know from experienced minibike racers what's worked best for them even if it's no tension. Thanks
