Has anyone installed a Baker 24 tooth engine pulley? What was the result? Is there a lot of slop in the belt tension??? Would you do it again? | ||

We had a 26th on the Tuber we had back in the day. Worth the hassle back then. Not what you were asking, we know. Regards | ||

How many teeth are stock? | ||

30 according to the Buell parts catalog for 2006 Ulysses. The result will be lower final drive ratio. Good for acceleration and little else. With a 6 tooth drop, I doubt there would be any tension on the belt. Whether that is good or bad, I don't know. | ||

Why not just go with the XB9 primary? In fact, there's one in FM. http://www.badweatherbikers.com/buell/messages/21/686308.html?1341717587 (Message edited by rdkingryder on July 08, 2012) | ||

I thought 27th was the US model? | ||

XB9 seems to be a popular swap. Seems to me the Baker would easier to swap back and forth. Around here in Appalachia, you need the lower gearing for these lil 1 lane back roads. If you're a flat lander - or if you decide to go cross country, stock gearing is best. | ||

I see what you're saying Conchop. My concern, with dropping 6 teeth on the front pulley, would be belt wrap and tension. Or, specifically the lack there of... Does "Baker" offer a shorter belt to go with the 24 pulley? Have you called Baker? If I read their web info correctly they offer 26 and 28 tooth. http://bakerdrivetrain.com/sportster-buell-parts-and-accessories A 28 would probably be plenty and would probably not need a shorter belt. I think you need to call Baker... (Message edited by teeps on July 11, 2012) | ||

CC, the XB9 swap is pretty easy, maybe 2 hours and going cross country isn't an issue. I tach 3800 rpms at 70mph, about 300 higher than stock, but the bottom end grunt is alot better. Still get around 45mpg. | ||

As far as belt slack is concerned, perhaps the spring loaded Trojan tensioner could bring it up. Perhaps the XB9 swap is the best overall solution as it has been a proven option. | ||

One other thing points towards the XB9 primary: The speedometer sensor is connected to the output shaft of the tranny. If you swap the primary gearing, your speedo will still be correct. | ||

Another thing leaning towards the XB9 primary... those Baker parts don't actually fit a Uly. (As far as I can tell). You had my hopes up. I'd love something I could swap easily. Gear the uly down a bit for my normal commuting, but gear it back up for longer road trips (where I might be sustaining 80 mph for hours at a time). If I didn't have an 07 (with the weaker crank) I would probably have already done the XB9 primary conversion. | ||

I've yet to ride a Buell that the speedo was anywhere near correct... | ||

Ride mine. Dash says 61, GPS says 60, close enough for government work  | ||
| Natexlh1000 |
That's a whole mile off! What if you were on a tight schedule? | ||
| Froggy |
It isn't always 1mph. On my last timed rally I turned the key off while coasting down large hills to compensate, but at that point it is all within the variance of the tires, gps accuracy, etc. | ||

Not a good idea turning the motor off while coasting for long distances because of the dry sump motor. Oil does not get circulated through out parts of the drive train that need it. This is what I have been told. Here is a post on the xb board on an area that does not get lubed when coasting with the engine off. http://www.badweatherbikers.com/buell/messages/32777/686824.html?1342130952 (Message edited by jcbikes on July 12, 2012) | ||

You obviously haven't seen my riding. Also, don't roll the bike around for the same reason, that means start it in your garage before moving it. Also, don't start your motor, it causes wear due to not being oiled and up to temperature. | ||
| Jcbikes |
Just saying "coasting for long distances." I am no expert but just passing along what I have been told about dry sump motors in general. I am also not saying it was the cause of the xb9 in the link.  | ||
| Afsoc_commando |
dry sump has no effect on the tranny... your oil pump handles the engine and your clutch basket and primary are in an oil bath. Coasting will not hurt the engine if your in neutral. | ||
| Conchop |
Damn thing would have been perfect with a six speed tranny! | ||

I coasted downhill with the engine off for about a mile or so in AZ this spring. Made it all the way back to KC with nary an issue! |
