This includes SX, XC, EXC and XC-W models. The cover will work with stock or aftermarket pipes.\u003c\/p\u003e\n\u003cp\u003eThis cover will not only enhance the aesthetics of your bike, but it adds power at low throttle and low\/mid revs where most riders need it most! It is ideally suited to trail riders and hard enduro riders who want smooth power delivery and maximum torque at low revs, before the powervalve opens.\u003c\/p\u003e\n\u003cp\u003eOur TBI Oversize Powervalve Cover is not just bling! Its been carefully designed and tested to ensure noticeable gains at low\/mid revs. It is most effective between \u003ca href=\"tel:3000-5000\"\u003e3000-5000\u003c\/a\u003e and at low throttle, adding a torquier feel to the power delivery.\u003c\/p\u003e\n\u003cp\u003eCheck out the dyno results on our 2024 KTM300EXC TBI shop bike. This bike is running a Medium Compression TSP head with a TSP ECU tune. Adding the Oversize Powervalve Cover further increased hp and torque down low by a noticeable amount.\u003c\/p\u003e\n\u003cp\u003eDont be fooled by cheap bling covers on the market, they are not the same product as our TSP Oversize Powervalve Cover!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does it work?? \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt high revs the pressure waves travelling back and forth through the expansion chamber help to supercharge the cylinder, filling it with more fresh fuel\/air than it would otherwise receive. This supercharging effect, and the extra power that results, is often what riders feel when they say a 2 stroke is “on the pipe” at higher revs.\u003c\/p\u003e\n\u003cp\u003eThe downside of this phenomenon is that the same pressure waves that help to supercharge the cylinder at high revs actually make it harder for fresh charge to enter the cylinder at lower revs. This causes a drop in power at low\/mid revs. To combat this some powervalve systems incorporate a ‘Torque Chamber’. A Torque Chamber is a chamber on the side or top of the cylinder which is opened and closed by the action of the powervalve. When the powervalve is closed or down, the chamber is open to the exhaust gasses. When the powervalve opens at high revs the chamber becomes closed to the exhaust gasses.\u003c\/p\u003e\n\u003cp\u003eAt low revs, when the chamber is open, the pressure waves travelling through the expansion chamber enter the Torque Chamber and are dissipated somewhat, losing some of their strength. The reduction in the strength of these waves helps to improve the filling of the cylinder with fresh charge. Therefore, the Torque Chamber adds extra power down low by reducing the negative impact of the pipe in this rpm range. By adjusting the volume of the Torque Chamber we can further reduce the negative impact of the pipe at low revs, and increase power even more. This is how the TSP Oversize Powervalve cover helps to increase power at low revs (approx 3000-5000rpm).\u003c\/p\u003e\n\u003cp\u003eIn order to find the ideal volume of the chamber we spent months dyno and track testing various designs until we settled on a design that made a noticeable improvement in low\/mid torque.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eFits : \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable class=\"table table-bordered table-striped\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand, type\u003c\/td\u003e\n\u003ctd\u003eYear\u003c\/td\u003e\n\u003ctd\u003eYear\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGAS GAS\u003c\/td\u003e\n\u003ctd\u003eEC 250\u003c\/td\u003e\n\u003ctd\u003e2024 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGAS GAS\u003c\/td\u003e\n\u003ctd\u003eEC 300\u003c\/td\u003e\n\u003ctd\u003e2024 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGAS GAS\u003c\/td\u003e\n\u003ctd\u003eEX 250\u003c\/td\u003e\n\u003ctd\u003e2024 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGAS GAS\u003c\/td\u003e\n\u003ctd\u003eEX 300\u003c\/td\u003e\n\u003ctd\u003e2024 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGAS GAS\u003c\/td\u003e\n\u003ctd\u003eMC 250\u003c\/td\u003e\n\u003ctd\u003e2024 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHUSQVARNA\u003c\/td\u003e\n\u003ctd\u003eTC 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHUSQVARNA\u003c\/td\u003e\n\u003ctd\u003eTE 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHUSQVARNA\u003c\/td\u003e\n\u003ctd\u003eTE 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHUSQVARNA\u003c\/td\u003e\n\u003ctd\u003eTX 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eEXC 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eEXC 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eSX 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eSX 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eXC 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eXC 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eXC-W 250\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKTM\u003c\/td\u003e\n\u003ctd\u003eXC-W 300\u003c\/td\u003e\n\u003ctd\u003e2023 - 2025\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Flawless","offers":[{"title":"KTM EXC 250 TBI  Powervalve Cover 2024-","offer_id":51080071151882,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"KTM EXC 300 TBI Powervalve Cover 2024-","offer_id":51406485127434,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"Husqvarna TE 250 TBI Powervalve Cover 2024-","offer_id":51406485160202,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"Husqvarna TE 300 TBI  Powervalve Cover 2024-","offer_id":51406485192970,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"GasGas EC 250 TBI  Powervalve Cover 2024-","offer_id":51406485225738,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"GasGas EC 300 TBI  Powervalve Cover 2024-","offer_id":51406485258506,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true},{"title":"KTM SX 300 TBI Powervalve Cover 2024-","offer_id":51406485291274,"sku":null,"price":149.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0534\/7380\/4477\/files\/IMG-6669.webp?v=1750938446","url":"https:\/\/www.sick-motos.com\/en-ie\/products\/tsp-ktm-group-250-300-tbi-2023-on-oversized-powervalve-power-valve-cover","provider":"Sickmotos-Styles ","version":"1.0","type":"link"}
