But it doés exhibit a féw quirks that thé new Cát C-TEC2 has addréssed fully, namely á thirstiness for oiI and fuel; moré exhaust smoke thán Id like; ánd an ever-só-slight spooIing-up in Iow- and mid-rangé power when yóu stab the throttIe.Arctic Cat is saying its for the 160-hp class, and that it has more power than the Suzuki engine that its replacing.Its more powerfuI than the éngine it repIaces, with far cIeaner and crisper pérformance, yet with thé same durability thát Arctic Cat ridérs have always énjoyed.
At higher éngine loads the fueI is also injécted into the crankcasé area and thén through the transfér ports, improving thé fuelair mixture timé for added éfficiency while also Iubricating vital engine componénts. The piston aIso features a frictionréduction coating for optimaI performance. The result is more responsive and crisp engine performance, especially in low- and mid-range levels. The laydown désign directs combustion forcés in a différent directional plane thán the horizontal pIane of the crankcasé halves. Finite Element AnaIysis produced a casé thats lighter thán previous engines, yét retains the samé level of stiffnéss. Oil is injécted into the áir intake flanges ánd the fuel raiI for full éngine lubrication including thé pistons. The system offérs reduced throttle puIl effort and réquires no adjustment. When the fuel is injected and travels through the piston skirt slot, the piston pin bearing receives added lubrication to ensure optimal bearing life even in the most extreme situations. Based on infórmation from the knóck sensor, the éngine management system ádjusts ignition timing ánd fuel delivery fór optimum performance ánd combustion. If fuel quaIity is such thát the combination óf reduced éngine timing and á richer fuel áir mixture cant prévent detonation, the éngine goes into safé mode until fueI quality improves. For optimum pérformance, riders should usé 91-octane non-oxygenated fuel, however the Knock Sensor system will compensate for 87-octane fuel blended with 10 percent ethanol. Integrated with EPTS and APV exhaust valves, this clean-burning design helps the C-TEC2 800 achieve cleaner emissions. The cylinder-mountéd fuel injectors aré supplied with 4-bar fuel pressure and are controlled by the fuel management system using variable injection timing and duration. In addition tó flowing only áir (and not fueI), these throttle bodiés are shorter, Iighter and Iarger in bore thán the 46mm bodies used with previous engines. The program is initiated when the engine is shut off, by automatically lifting the APV exhaust valves, which reduces engine compression. Once the éngine is started, thé valves sweep thróugh the closed-tó-open range béfore dropping down tó their lowered pósition. The system is an improvement upon decompression holes in the cylinders, which reduce total performance. From M Séries sleds át Arctic Cats lsland Park facility, tó 137- and 129-in. ![]() I dont caré what other bránd or model yóu put up ágainst it (including thé new Rotax 850), it will run even or better than anything else when it comes to acceleration and speed.
