    I was just wondering since on all my dirt bikes I used to change out the front sprocket depending on what type of riding I was doing, so I started wondering if anyone has ever done that on their Dog? [​IMG] I see that baker makes different sizes, as far as how many teeth are on it, and Curtis has different lenth belts so if someone wanted quicker accelleration from a stop then all he'd have to do is increase the front by one tooth and it will rev quicker, you might even be able to still use the original belt if ya only went one tooth, anyway just wonder'n! [​IMG] :D

    I remember this being discussed a long time ago and if I remember right (yea right) the only sprocket available was the one on the bikes and they were all the same. Keep in mind that I sometimes have trouble remembering what was for supper last night :)

    I stand corrected, a smaller tooth on the front is quicker revving! Thanks Eric!

    I remember thinking about this a long time ago cause I like to cruise at about 65'ish and I'm kinda almost between gears at that speed. Too low RPM for 5th gear.

    Do you know what the stock count is on our Front Pulley's?

    It's a 34 tooth, but Pat say's he thinks the only one available for our bikes was the 34 that it comes with.

    This is on the baker website,

    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.

    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.



    Machined from billet rounds of 1045, these stock replacements are toughest pulleys available on the market. With lightening holes added to help reduce rotating mass, and a maximized cross section reach the balance between strength and weight reduction, they are a step above the mass produced stock units. Available in the following tooth counts.

    Why? My 107 will about throw you off the bike as it is and will get to 110 mph and more. Dirt bikes are different than highway bikes. They dont have the torque that our long stroke engines do. The only way I would change sprockets would be to go drag racing and then I would not be sure about that.

    On a bike like these, you would be changing the gearing to suit your style of riding. If you want to cruise at 60 and use 6th, you may want to gear it differently. I know 6th is useless on my bike below 70-75ish. Or at least it is lugging the bike more than I like. If you run backroads and twistie roads, you might want to change the gearing a bit to let you hold one gear longer and avoid shifting as much. There are lots of reasons to perfect the drive ratio to your riding style and intended useage.

    When I put the OP on my 03, it changed the ratio from the engine to the trans. It has a lot of torque, but I find myself looking for 6th gear around 60 mph. So running the back roads, up and down hills, I have to do a lot of shifting between 5th and 6th alot.

    Thanks Adam. I knew the six speed bikes were geared for higher speeds in sixth gear and did not think about not being able to use it in some parts of the country. I don't have that issue since my old school beater only shifts four times.

    Under WOT in 1st and 2nd my tire spins, not sure what your looking for? Once the tire spins there isn't any traction and if it didn't spin I'm not to sure you could hang on. Of course you could fit it with a drag slick and lay on the tank and put your feet on the rear pegs to help you, but at the end of the day you still have a cruiser. Enjoy it for what its intended for:whoop::old2:
