If you're running up to 300 line amps this is the kit for your GTS or FW11. This will only work on the Midwest Mini Mods swingarm. For the high power you will need the right side only option upgrade for the qs165 arm. It is sold separate for $100 or you need to ship your current arm to our machinist for modifying. This is a $55 fee and includes the shipping back to you. You will also pay to ship it to him. If you're running a 3" or 5" arm the high power kit needs a deeper and wider motor slot and a slot added in the rear for the pulley. Depending on torque settings, you may need to run less power, if the belt is skipping and tensioned properly you may have to reduce power eliminate any skipping. We have not done much testing and will need your feedback on power you're running and how it's handling it!
These belt systems are meant for street use only. Please be sure to properly tension these belts and recheck them after the first few hard rides to make sure they have not stretched and gotten loose. This kit includes a 18mm wide belt, a 90-120 tooth rear pulley option, and a 20 tooth motor pulley. Belt brand will vary depending on our stock. These will only work on pit bike wheels that we sell or the same mounting pattern from elsewhere.
