i have a question for anybody. in my TXL, it has a polaris clutch, serial number 414505, and then a couple spaces and the number 403. no idea what this means, but maybe some of you do. i was just wondering what the model was, and if it was a pretty good one or not. also, it has the stock weights, but it has an aftermarket spring, which dad thinks is silver. i can put all of my weight over it (170) and it will compress about an inch. it engages at about 5000 rpms, and i was also wondering if this was any good. again, thanks for all your help. it would suck if i had all these questions and no one to ask.
