The geometry of this cover works exceptionally well, there are plenty of other covers on the market that will do virtually nothing but look bling.

It’s perfect for trail riders and hard enduro riders who seek smooth power delivery and maximum torque at low revs, before the powervalve opens.\u003c\/p\u003e\n\u003cp\u003eOur TBI Oversized Powervalve Cover is not merely a decorative accessory. It has been meticulously designed and tested to ensure significant gains at low to mid revs. Most effective between \u003ca href=\"tel:3000-5000\"\u003e3000-5000\u003c\/a\u003e RPM, it provides a torquier feel to the power delivery at low throttle.\u003c\/p\u003e\n\u003cp\u003eCheck out the dyno results on our 2024 KTM 300 EXC TBI shop bike, equipped with a Medium Compression TSP head and a TSP ECU tune. The addition of the TSP Oversized Powervalve Cover noticeably increased horsepower and torque at low revs.\u003c\/p\u003e\n\u003cp\u003eHow does it work?\u003c\/p\u003e\n\u003cp\u003eAt high revs, 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 resulting extra power is often what riders experience when a two-stroke engine is “on the pipe” at higher revs.\u003c\/p\u003e\n\u003cp\u003eThe downside is that these same pressure waves, which assist in supercharging the cylinder at high revs, make it harder for fresh charge to enter the cylinder at lower revs, causing a drop in power at low to mid revs. To combat this, some powervalve systems incorporate a ‘Torque Chamber’. This is a chamber on the side or top of the cylinder, opened and closed by the action of the powervalve. When the powervalve is closed or down, the chamber is open to the exhaust gases. When the powervalve opens at high revs, the chamber is closed to the exhaust gases.\u003c\/p\u003e\n\u003cp\u003eAt low revs, with the chamber open, the pressure waves entering the expansion chamber dissipate somewhat, losing some strength. This reduction in wave strength helps improve cylinder filling with fresh charge, thereby increasing power at low revs by mitigating the negative impact of the pipe in this rpm range. By adjusting the volume of the Torque Chamber, we can further reduce this negative impact and boost power even more. This is how the TSP Oversized Powervalve Cover enhances power at low revs (approximately \u003ca href=\"tel:3000-5000\"\u003e3000-5000\u003c\/a\u003e RPM).\u003c\/p\u003e\n\u003cp\u003eTo determine the optimal chamber volume, we spent months conducting dyno and track tests with various designs until we settled on one that provided a significant improvement in low to mid torque for both the 250 and 300 TBI engines.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"X-DURO-WORX","offers":[{"title":"Default Title","offer_id":52358608093511,"sku":null,"price":118.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/9076\/3847\/files\/IMG-1939.webp?v=1758142882"},{"product_id":"erm-ecu-reflash-module-ktm-tbi-tpi-4-stroke-tsp-fsp-tuning-tool","title":"TSP ERM ECU REFLASH MODULE KTM TBI, TPI \u0026 4 STROKE TSP FSP TUNING TOOL","description":"\u003cdiv\u003e\n\u003cp\u003eNote for 18-19 TPI you need this cable \u003ca href=\"https:\/\/rutherfordracing.co.uk\/product\/tsp-erm-adapter-harness-required-for-2018-2019-tpi-models\/\"\u003ehere\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003efor 4 Stroke KTM 2017 on  you need this cable \u003ca href=\"https:\/\/rutherfordracing.co.uk\/product\/tsp-erm-adapter-harness-required-for-last-two-4t-generation-models\/\"\u003ehere\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/tsp-erm.com\/product-features\/\"\u003eTSP ERM Informational website: CLICK HERE\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eThe most exciting new product TSP has ever created brings new levels of tunability to the current generation of 2 stroke dirtbikes.

On the dyno it is one of the softest 300s we have seen in a number of years, only making 45rwhp at peak power, compared to the previous TPI models at around 49 and the new 300XC TBI at 57. Likewise at low throttle and low\/mid revs its still very smooth but lacking in torque which actually makes riding in some situations much more difficult. When testing a stock 2024 300EXC side by side with a 2022 300TPI with our head and ECU in Romania in July 2023 we found that the tuned TPI was much easier to ride in challenging hard enduro conditions because it allowed you to ride a gear higher in most situations, using lower revs and less wheel spin, and as a result it was able to lift the front and tractor up tricky sections far easier with less throttle and less effort.\u003c\/p\u003e\n\u003cp\u003eThe aim for developing this new power kit for the 2024 bike was to increase low end torque and pulling power while maintaining excellent traction and smoothness.

On the track the new 2024 bike is now an absolute pleasure to ride with the extra grunt the power kit offers, plus the extra smoothness that the TBI engine gives. The overall result is a powerful yet very smooth engine which is easy to ride almost any conditions.

It completely transforms the TBI into a trail weapon. This head pushes the limits of normal 98 RON pump fuel at sea level (approx 91 in the USA) but it can be used in normal trail riding conditions safely in order to achieve maximum bottom\/mid performance. Do not use this this head at sea level for MX, deep sand riding or sustained high rpm riding unless you are using high octane fuel. Its not ideal for Hard Enduro due to the aggressive low end delivery and the higher tendency to increase heat in the engine.

This kit allows you to run premix, or you can continue to run the stock oil pump. The kit comes with all the necessary hardware for a simple installation? including fuel hose, hose clamps, an injector blank (installed in the right side of the cylinder) and a 3D aluminium printed injector mount.

It can now perform similar to the 150 SX carb models, while retaining the stock injectors and without risking reliability. Our new TSP Over Rev tune for the 150 TPI lifts peak power from just over 10,000 rpm all the way up to 11,600 rpm, with an increase in peak power of over 6hp!! Compared to a stock 150 TPI the Over Rev tune makes more power everywhere above 8,000 rpm and the way it rides is totally different out on the track!\u003c\/p\u003e\n\u003cp\u003eThe trick to getting the 150 TPI to run at much higher revs lies in the ECU mapping and the exhaust pipe. We have tested extensively with the Scalvini 150 TPI pipe which focuses power higher in the revs, but not quite as high as the SX pipe. The Scalvini pipe gives more mid-range than the SX pipe, but signs off slightly earlier. In our opinion, its a great middle ground, making the Over Rev tune extremely versatile in both high revving situations, as well as slower technical riding. The 150 TPI with our Over Rev tune is one of our favorite bikes to ride.’ The ‘fun-factor’ is through the roof!!\u003c\/p\u003e\n\u003cp\u003eTSP has developed significant changes to the ECU mapping which allows the stock ECU and injectors to supply enough fuel for the 150 TPI to rev to the moon. This cannot be achieved without changes to the ECU and there are currently no other tuners offering anything like this tune! Running a higher revving pipe with the stock ECU mapping leaves the bikes running extremely lean and the end results can be disastrous.\u003c\/p\u003e\n\u003cp\u003eThis package will transform the power delivery of your TPI.

We modify both Map 1 and Map 2, with a more noticeable difference between the maps compared to the stock maps. Both maps have more oil everywhere compared to stock. Map 1 is the fully tuned map delivering maximum performance. Map 2 has less ignition advance and more fuel than Map 1 and is softer everywhere. Map 2 is the ‘safe’ map we suggest using for prolonged high speed riding, deep sand, or if you want to temporarily reduce power in very technical terrain.\u003c\/li\u003e\n\u003cli\u003eScalvini Factory Cone exhaust pipe\u003c\/li\u003e\n\u003cli\u003eSBMP idle screw and spring, necessary to do the ‘idle screw mod’.
