Why would harley put a smaller ''20mm'' wide belt on fatboys starting in 07, when they went to a bigger motor and a bigger rear tire?

The newer style belts are Kevlar and do not need to be as wide as the older styles. They can handle the same torque while being thinner in width. Like above, also for clearance.

How do i change the gearing on a 2005 sportster 1200c

if its chain, try different sprockets, bigger front will give lower rpms ,and pull longer ,and be faster

if you go rear, smaller will lower rpms, and be faster, bigger rear will be quicker but top speed will not be as fast
not sure if there is a speed sensor , that needs to be changed,
i have the same bike, and am wanting the bigger front pully stock is 29 i think , and there is a 30,and a 32 tooth pully for the belt drive models! sweet product , not belt change either!, but like i said i read something about a speed sensor that needs something to correct it

I would like to know how i could put a bigger tire on my 2006 sportster like they have on the 2011

I would think that you'd have to at least replace everything from the swingarm back but this may result in a misalignment of the front and rear final drive belt pullies. There's more to installing a fat tire than simply cramming it under there. Harley may have went to the narrower belt on the Sporty like they did on the Big Twins. Having never done this, I'm really not in a position to advise you on it.

Good Luck

How do you adjust and line up the rear tire on a 2004 Fatboy?

The best way to do this is to measure the belt tension adjuster bolts on either side of the swing arm. They should both measure the same. When adjusting the belt, get both bolts at the same measurement. Then adjust the bolt to push the tire to the rear the same on each side at a time. Like if you turn the right bolt a quarter turn, do the same with the left side bolt. Always adjust the bolt pushing the axle to the rear. If you get the belt too tight, loosen the bolts at least two turns, bump the wheel forward and start going backwards again, this time in smaller increments. Once you are finished, the two bolts should measure the same length. This almost guarantees that the axle is 90° of the centerline of the bike.

Good Luck

I have a 1992 Ford Bronco with a 5.0 Motor. I just purchased it about a month ago. The alternator went out on it and was just put in before I recieved the truck. I went to the store to purchase a new one...

go back to the auto parts store and ask to see one from a 1987-1991,its possible being a 1992 (which techically was built in 1991) was built with older design parts like the brackets and alternator.Keep in mine,anything older than a 87 would have had a "V" type belt system and anything newer would have a SERPENTINE belt-which is a wide flat belt that goes around all the pulleys

Replace drive belt on 1200 harley

To change the final drive belt on a Sportster is much simpler than doing the same job on a Big Twin Harley.

Support the bike so that you can remove the rear wheel, right rear shock absorber, the belt guard, and the front pulley cover. Take the old belt off and install the new one. Put the bike back together and adjust the belt to have about a 1/2" up and down movement in the middle of the belt with 10 pounds of force applied. Make sure your rear brakes work properly before you ride the bike.

While installing the belt, do not bend the belt in a radius any smaller than 4". Bending the belt too tightly will damage the cords inside the belt and may cause premature failure of the belt.

Final Belt Drive on HARLEY DAVIDSON

Belts = quite, durable, less cost to replace.
Chain = noisy, last longer, messy oil spots on floor, good ones cost $400.00 or more, have to keep adjusted, hard to break. Im a chain man myself.

Change the belt on the machine

Usually the easiest way is to put the belt on the smaller pulley first and then start it on the bigger pulley on one side and then turn it onto the bigger pulley by spinning the pulleys to get the belt to direct itself onto the larger pulley little by little. Using a flat-headed screwdriver can help pry the belt on and keep it from falling back off of the larger pulley while turning it to get the belt fully on. If you have any other questions about this, let me know.
