baker aluminum and steel pulleys drivetrain info 1985-2006 big twin pull on this for high performance applications we have lightweight aluminum alloy pulleys and for long life durability we offer steel pulleys both types are american made by the same kind of cnc gear cutting machines that make our gears and shafts all big twins with a belt drive from 1985-up have a 32 tooth transmission pulley changing to a different pulley with more or less teeth will change two performance attributes of your american machine rear wheel torque and cruising rpm increasing rear wheel torque will increase acceleration installing a pulley with more than 32 teeth will decrease your acceleration through the gears and decrease your cruising rpm installing a pulley with less than 32 teeth will increase your acceleration through the gears and it will also increase your cruising rpm this is called engineering compromise to get one thing you have to give up another however our baker 6-speed overdrive allows you to `cheat engineering compromise it is common for our customers to install a 30 tooth pulley when they install our 6-speed overdrive this gives them a 7 increase in rear wheel torque and an 8 lower cruising rpm on the highway it is truly the best of both worlds for your american v-twin pulley sprocket tooth count wheel torque increase cruising rpm in 6th transmissions primaries aluminum alloy race pulleys 29 tooth race pulley p/n 29bd-56 30 tooth race pulley p/n 30bd-56 31 tooth race pulley p/n 31bd-56 32 tooth race pulley p/n 32bd-56 33 tooth race pulley p/n 33bd-56 34 tooth race pulley p/n 34bd-56 29 30 31 32 33 34 +10 3017 +7 2916 +3 2822 0 2734 -3 2648 -6 clutches 2573 no belt length change is required with a 31 tooth pulley change cruising rpm in 6th at 75 mph compare to 3179 rpm with a stock 5-speed aluminum alloy race pulleys baker race pulleys are the lightest pulleys available a stock 32 tooth harley pulley weighs 5.2 lbs and our 32 tooth race pulley weights 2.0 lbs a 61 weight savings this weight difference means much less `flywheel effect and allows your engine to rev quicker absolutely required for performance applications race pulleys are hard anodized for wear resistance and corrosion protection drivetrain tuning steel long life pulleys these pulleys are made from a solid chunk of steel and are 23 lighter than the stock cast iron piece we recommend long life pulleys for performance applications where 100,000 mile pulley life is required designed for long distance touring applications with mild to moderate engine performance upgrades note pulley changes may require a belt change this depends on 1 where your axle adjustment currently is and 2 the pulley that you are changing to of teeth steel long life pulleys 29 tooth long life pulley p/n 29bd-56f 30 tooth long life pulley p/n 30bd-56f 31 tooth long life pulley p/n 31bd-56f 32 tooth long life pulley p/n 32bd-56f 33 tooth long life pulley p/n 33bd-56f 34 tooth long life pulley p/n 34bd-56f tools 45 www.bakerdrivetrain.com 1-877-640-2004
