a disc partially cut away and attached to the end of the crankshaft opens and closes an. D- transfer cycle begins & exhaust cycle continues. It's also possible to design your own combustion chamber, just take a blind combustion chamber and you can make any type that you want. C- exhaust cycle begins & primary compression continues. This service is for 2011-20 KTM SXF/XCF and 2014-2020 FC/FX/FS Husqvarna Closed Course 4-stroke Fuel Injected MX bikes Only works for KTM SXF/XCF and Husqvarna FC/FX/FS Models With our ECU Tuning we are able to reduce Flameouts by about 50 normally. Another advantage of the material is its resistance to detonation. The explanation of this phenomenon is the use of a special aluminum alloy which has a very good heat transference. Combustion chambers are available in different volumes.ĭuring intensive tests, on the racetrack as on the VHM testbench, the cylinder head showed a better temperature development in the cylinder head. This makes it very easy to adjust the combustion ratio to different tracks and fuels that are used. The 2-stroke enduro range is fitted with a frame-mounted oil tank featuring flexible mountings, which greatly improves durability and reliability. The combustion chamber is very easy to change, just untighten the cylinder head, take it off and you can change the combustion chamber. Pre-mixing 2-stroke fuel is a thing of the past for KTM XC-W TPI owners. With the experience gained in two-stroke tuning, VHM develops products of high quality. VHM produces exchangeable cylinder heads for two-stroke engines in motocross and road racing.
