850 Polariksen mallikohtainen keskustelu alkaa tästä. Joko moni muu klikkasi ostoskoriin tietämättä tämän enempää aiheesta. Some key points of the engine are; -increased crankshaft diameter and assembly process to increase strength and reliability -different clutch taper -greatly increased PTO crankshaft bearing load area (wider and diameter). -new piston design with much longer skirt to decrease piston slap -cylinder skirts extend into crankcase deeper to give more strength and piston support - “Shrink wrap” cylinder head water jacket design to increase cooling efficiency -coolant flow through the engine is optimized for maximum power output and consistency -new combustion chamber design for reliability with varying fuel quality. The spark plug and the cylinder head around the plug is extended into the chamber. -new v force reeds -new Dell Orto throttle body, with holes drilled in the throttle blades for idle air bypass. You may now adjust the idle rpm if desired without affecting the TPS baseline setting. -new magnetic/hall sensor type TPS, no adjustment required or possible. TPS is synched during initial assembly. -exhaust sensor in the main pipe and in the muffler, which allows the ECU to better determine fuel and ignition requirements. -new simpler VES system design, with cleaner, more consistent operation. Also, better overall power as a result of better cylinder pressure sealing. There are many other points to the new engine, which I am missing. One key fact which proves the power this engine makes, is that Polaris also designed a new drive belt for it. The primary clutch has 6-gram heavier weights than the current 800HO yet has the same suggested full throttle rpm. If you attribute 2 grams of the weight increase to the harder belt, 4 more grams at the same rpm means a lot more power is being made. I was not able to confirm any other clutching calibration. During the ride, we had a mixture of models, with 600, 800 HO, and the 850 engines. We were therefore able to do a direct comparison back to back, while riding the different 2019 jenkkikuvasto löytyy http://polaris.hs.llnwd.net/o40/sno/2019/documents/pdfs/pol-my19-broch-keyline.pdf Oispa jo 2019 talvi!
