Need help with a tuning kit, how do you tune your scooter, which kit should I choose, and all general tuning and modifcations questions are for in here.
Hi - scootersing did a comparison feature of expansion exhausts and NK road/ rally was overall top choice. PM me your email address and I'll send you a copy of the review
Can't fault the NK apart from maybe the tail can so I changed to Gianelli. Power is around 7.5 k peak but will rev on. Although they don't look as well made as a JL they're certainly stronger than the JL4 I replaced.I ran 4.8 gearing and on the right day would hit mid 80's at 8.5k revs
I used one for a couple of Years on my TS1. Good power delivery but poor ground clearance if you like to get your knee down. I used to ground mine on both sides. End can eventually snapped off at the stinger. Repairable but currently gathering dust.
