Default 27 or 29 Tooth Pulley

I have done the 1200 conversion and I am wondering if anyone has changed the stock 27 tooth 883 tranny pulley to the 29 tooth that comes with a stock 1200? I am wondering if it makes a difference in the amount of vibration and increases cruising speed. Thanks

I haven't done it, but there are a large number of people here who have. From the reports given, it does reduce vibration at higher speeds, but doesn't do a whole lot for your top speed. Mainly, all it does is reduce the number of engine rotations compared to the number of wheel rotations. The upside is that you'll have a little more top-end power, but you do lose some of your off-the-line power in the process. It depends on where you do most of your riding: if you ride in-town more, stick with the 27. If you're a freeway fanatic, go to the 29.

i had to change my sprocket cuz it loosened up on me, so i went with the 29 tooth just to see what it would do.
seemed to actually make it pull harder through the gears i like it

has anyone ever changed out their rear belt pulley to a smaller one or anything as well? I heard if you go with a bigger pulley in the front and maybe like a smaller 55 tooth pulley in the rear instead of the stock 61 tooth, that it reduces vibration and the like as well.

I have both the 27T and the 29T for my 2003 1200.

I switch back and forth when I feel like it....

The 29T gives you less RPMs at any speed (Doh)
Vibes will be less or at least it will shift the vibe zone to a different MPH.

I like the 27T with my 6 speed since if gives more torque in all gears
and I still don't lose the top end. But that a pricey upgrade.

The answer really depneds what kind of riding you do.
Mostly highway? 29T
Mostly around town and all, 27T

Remember the Speedo will be off when you switch pulleys

no, but have gone to a 70 tooth from 68 tooth. i don't think changing the sprocket actually changes the amount of vibration. It does change where in velocity of your bike vibration occurs. My 1200 vibrated terribly at 64-68mph. I spend a lot of time at 65mph. Drove me nuts. I dropped to a 28th and up to a 70th no evil vibes from 60mph up. It also leaves the stop light a whole lot faster. The vibration is still occurring at the same RPM range. I just moved it down the speedometer. Also note that I have a 06 1200C. My 2¢ worth.

Default Clear this up for me.

I do a lot of interstate riding on my stock 2006 883C. I feel like I need another gear. Tell me the set up I should use and be specific (front and rear). This is something I must improve on my ride. Thanks in advance.

If you want engine rpm to be lower at interstate speeds, then you can buy a 29 or 30 tooth front transmission pulley, and I have looked but i can't find a 55 tooth rear pulley, but that would be good set up for that. You could also change the primary sprocket to a 38 tooth. Anyone of those should give you more top end. Your torque will go down but for your preferences i don't think that matters.
