Suppose I want just a bit more oomf out of the X1. Would a 26 tooth aluminum sprocket be the way to go? Are there drawbacks other than some loss of high end power? Would it be better to stick with steel and still lose a tooth? I know nothing about this. |

Here's the general rule, depending upon the type of "ooompf" that you want--(More acceleration or more top end): More teeth on the rear and/or fewer teeth on the front will give you an acceleration boost at the expense of the top end. The bike will rev more quickly, but the red line will come up earlier. Fewer teeth on the rear and/or more teeth on the front will give you more top speed, at the sacrifice of acceleration. DW |

I understand the basic principles. I guess I'm looking for specifics and experiences. I'd like a bit more snap off the line, but I don't want to do anything remotely damaging to the longevity of the bike, nor any of it's components. |

Anyone have experience good or bad with the Evolution industries Billet 26 Tooth Engine Sprocket? Or the Baker? Anyone have a price on the baker? Or a recommendation on steel vs. aluminum? |

Someone posted previously that they used an aluminum one and ate it up fast. I have no personal experiences with an aluminum sprocket though. For what it's worth. |

Depends on who you get the sprocket from...what material, if it's hobbed or stamped..natural finish or anodized...they are not all equal...the cheaper stamped ones are made from 500 series alloy...the better ones are from t-60 stock. The other selection point is steel is more durable, but adds unsprung weight...in either case, the most common killer of sprockets is changing them and using the old chain...chain and sprockets are a set..replace them as such. |

So maybe a steel 26 tooth from Baker would be the way to go. Still lighter than stock, and more torque. |

Low, I'm so with you about the gearing. I'd love to find a larger rear sprocket so I could use fifth gear! |

Fast, the steel adds sprung weight, which is why the aluminum pulley makes such a difference. The steel pulley is 2.8 lbs, while the Baker aluminum one is 0.8 lbs. A very significant change that accounts to less driveline power loss. |

baker also makes a steel that is 1/2lb lighter than stock. Does the aluminum wear down faster? are there disadvantages to it? |

Yes, the aluminum one wears quicker. I don't know how quick; I imagine it depends on how hard you ride.. |

IS THERE ANYONE HERE THAT HAS RUN ONE OF THE BILLET BAKER SPROCKETS AND CAN TELL ME HOW LONG IT WILL LAST!?!?!?!

I think Phelan hit it on the head. How hard do you ride? Do you take the bike to track days often? To be honest with you I have been thinking about doing the opposite to gain some more top end. (really looking for a lower rpm at 70mph) My bike will lift the front end in 1st and 2nd quite easily. How much more "oomph" do you need. Not sure if you already have the race ecm but if you don't it will make a big difference compared to the stock one. (PM me if you don't have the race ecm) |

Tom, I have the race ECM. I think I just want a bit more light to light fun. I've never taken my bike to a track day. I might, but honestly, I'm pretty afraid to dump it. I think I'll buy another next year expressly for this purpose. I use my X1 as daily transportation. Mine doesn't seem to lift the front end so easily in first, and I've yet to experience it in second. I have to work at it with the 3,000 rpm bump trick or really get on it, like WFO throttle. Mine is doing 3500 rpm at 70mph. you want lower than that?!?! |

LOL. Mine is doing 5500rpm at 120 or so. I'd prefer a litle lower but can't afford a Baker six-speed. |

Sporty, how do you hang onto the bars at those speeds? 80/85 and it stops being fun for me! |

Don't misunderstand, 85 is fine, as long as I just have to do it till I get to my brake marker. That happens less and less now, more it is 85 on the slab that I have a problem with. Maybe it is just me but I don't get the chance to use fifth gear much. A lower ratio would fix that. I wonder if only one tooth down in front would be enough to make a difference. |

I use 5th a lot. Amarillo has a lot of 45 and 50 mph limits in town, mainly because "town" is 20 miles wide and 15 miles long. Plus I travel outside of town every chance I get. |

BTW I too would like a taller front sprocket, but in billet . |

BUELLers: SPROCKETS 101: In 1997 my S3T came with a 29 tooth countershaft sprocket, "BUT" in 1998 S3's came with a 27 tooth countershaft sprocket ... The 27 tooth LOWERS the over all gearing ... Here is the give and take of this ... The 27 tooth gave more TORQUE at lower RPM's which allowed the THUNDERSTORM HEADS to perform better at lowers RPM's ... For those who wanted the RPM's/MPH at 100 MPH,well the best way to do this is to do a DYNO RUN ... There are 2 places to LOWER the gearing with less teeth which are: the motor sprocket and the countershaft sprocket ... The later EVO Sportster engines have a transmission sensor for the SPEEDOMETER, so when you change the countershaft sprocket, it changes the SPEEDOMETER RATIO which means you get the illusion of more MPH ... "BUT" if you decrease the teeth on the motor sprocket, it does not change the SPEEDOMETER RATIO ... Another"BUT" is that if you decrease the motor sprocket teeth too much you will have to get a shorter length PRIMARY CHAIN ... MAY THE LONG LASTING BUELL BE WITH YOU !!! |

I'd like to have a 26 tooth on the front but after this motor build it's just not in the finances. I do a lot more 0 to 45 - 60 than I do 120 anymore. |

Me too Kyrocket! That Baker steel sprocket may help some. I just talked to them and the change may be 125 rpm at 60 mph. I'm hoping for a bit more than that, but at least it is going the right way... |

Kyrocket: If you count the belt teeth on your countershaft sprocket, BET you will find that it is a 26 tooth ... |

$180 is not bad. I wonder if my X1 has a stock 26 tooth now? Only one way to find out I guess. |

Not bad, as motorcycle parts go I suppose. A pair of billet levers will cost more than that, and they won't help preformance at all! I wonder if there is anyone making rear sprockets for buell? |
