With a 29 instead of a 27?

29/27 = 1.074 and 27/29 = 0.931

So with a 29T front pulley instead of a 27, at a given engine rpm at in a given gear your speed will be 107.4% and your rear wheel torque will be 93.1% of what it was with the 27. Rwhp stays the same.

You must be looking at that one on E-bay that's about to sell ;)

The problem with the factory pulleys is they weigh a ton. If you're willing to pay a little more, there are lightweight alternatives available on the aftermarket, from 26T up through 30T. You can get'em in steel (somewhat lighter than stock), aluminum with a steel hub (way lighter than stock), or all-aluminum (featherweight).

Nope not e-bay my stocker took a crap on me so we have a Belt Drives LTD one that I bought as a quick fix. 29teeth, 356-T6 aluminum. Supposed to 1/3 the weight of stock. Well at least I will be riding tomorrow :D

different strokes for different folks ... that 29T front pulley that came stock on my S2 was one of the very first things to go. Couldn't stand it!

The 29t ROCKS, I notice a little loss of low end on the ol' butt dyno but all in all I like the low RPM cruzin in low gear.

Baker sells 26T all-aluminum and 26T & 28T steel pulleys (notice my ugly mug on that page ;) ). I have one of their all-aluminum 26T pulleys and you can't believe how light that thing is. I've run it a couple thousand miles on my M2 and a few days ago I swapped it out for their 26T steel unit, partly because I was concerned about longevity and partly because I need the ultra-light 26T for a race application. Well, no signs at all of a problem with the thing.

BDL makes 27T, 28T, 29T, and 30T front pulleys in an aluminum with steel hub configuration. Well, kinda anyway. I have a 30T and it's constructed that way, but the other day I got a 28T BDL pulley and it's all-aluminum, looks exactly like the 26T Baker except for the tooth count. I bought it through Drag Specialties and it's clearly represensted as being steel hubbed, but that's not what it is. Not that I mind, like the aluminum 26T it's destined for a race bike.

I've got 2,000 miles on that baby and will nevber go back to the iron one. Haven't look at it for wear but I do expect it to have a shorter life. Not something than concerns me. $160 (minus shipping) is well worth to me.

Aaron,
How long will the all aluminum pulleys last? When I removed my oem steel pulley at 50K miles it was just about to give up. The inside was just about to let go with only a very little bit of the spline left. I am thinking of putting a 30T aftermarket pulley on now. Do you think the 30T BDL would hold up on a bike that sees LOTS of miles. Does anyone make a 30T all steel?
Thanks,
John

I suspect the 30T BDL would hold up a long time, because it *does* have a steel hub, unlike the 28T BDL which is all aluminum.

Will the steel hub work it's way out of the aluminum at all?

Not a lot of people "carry" it but I'd think most BWB sponsors can order from DS or the other Baker and BDL distributors.

Yes, Tat may have some stock, if not, we can sure as hell get'em for you.

I've been running one of the BDL aluminum/steel construction pulleys on my FXR for years, no problems at all. Never say never, but it'd surprise me if the hub and pulley separated.

I ordered a 26 from Baker, it might help me out of the hole. The all aluminum does not bother me, I'll use a Permatex on the splines which should keep any movement/wear down.

Aaron,

My 28T is steel/aluminum but I have had it for about a year now. Still in awesome shape. Want to sell for a 29T one!

Thanks Ryan

Ryan, Maybe I could use your 28Toother,if shorter gearing might not work. An E-mail would be in order?

Why not just convert to a chain? The chain would be heavier than a belt, but it could withstand more severe conditions, sprockets would be lighter, you'd have a broader selection of sprocket sizes and best of all, you could know when a chain is worn out. I don't know how much an aluminum belt sprocket weighs, but I bet it's a lot heavier than an aluminum chain sprocket. It's also a lot easier to change a chain (on an S3,M2 or S1). Also, a chain and 2 sprockets is a boatload cheaper than a belt and its 2 sprockets. Belts are good for running superchargers; they're bad for propelling motorcycles IMO.

Crusty, I believe the belt "gives" and softens the impact on the drive line. Remember no drive cushion on Sportsters/Buells.

VR, the belt is made of Kevlar. It repels bullets. It doesn't give enough to matter.
Hmmm, it repels bullets, but rocks go right through it and cause it to break. Screwy, ain't it?

Rocks don't travel at 800 ft per sec and aren't made of lead. Oh yeah there are just strands of kevlar in the belt ;)

Crusty... take your Kevlar vest, and stab it with something like an icepick. Something with a lot sustained force with a small frontal area. Kinda like a rock pinched between a belt and a sprocket.

Also, I believe Kevlar, like carbon fiber, is a one shot deal. The material is destroyed as the energy from the incoming projectile is dissipated, protecting the wearer. So it works well (once) for bullets or "liberated" blades from jet engines, but would not work so well against something with a long sustained piercing force like a rock caught between a belt and a sprocket.

I have heard carbon fiber is similar... you can drive a F1 car into a wall and barely have any marks to show for it, but drive it back the the pits and tap the front of it with a hammer, and the whole thing will fall to pieces.

I watched some jet engine bladeout tests, and saw a kevlar engine cowling try and contain the mess in super slow motion. Quite the show. The first blade out was contained really well, the rest were not so pretty.

Blake , help me out. I still think the belt is easier on the drive train than a chain.

I converted my '88 FLHS to chain drive after the belt broke on I-71 on a Sunday afternoon, leaving me stranded 600 miles from home. that was at 80,000 miles. When I sold the bike, it had 125,000 miles on it and had experienced no drivetrain problems since the conversion. I repeat: chains are good, belts suck.

My cousins FLH did the same. We tossed on a temporary belt and got home. That week we put on a preeminent belt. Never broke again.

I agree with Crusty,

Yesterday my second belt broke due to a rock. You can clearly see where something punctured the belt then it snapped.

BELTS SUCK and Chains Good

My problem is finding a 52T rear sprocket up here in the middle of the atlantic ocean.

I'm thinking about changing my pulley. going to a 26T. Would I need to change the belt?
Thanks

My pulleys have flat spots over the tops of the narrowed-by-wear teeth and they only have 12000 miles. It looks like the hard chroming has worn right off 'em. I sense a chain in my future.
