What can I expect from a stage 1 or 2 kit for my XB9. I am not a racer. The bike is a street bike. I might have the occasional track day - but thats about it. I will be doing the 1050cc kit along with stage head work. I currently haver a Drummer (with Race ECM and KN filter) on the bike now. I was thinking about throwing on a Micron exhaust when I do the stage work. What kind of results should this work yield. |

http://www.nrhsperformance.com/dynoroom.shtml Check the dyno sheets that are the 2nd and 4th from the bottom - both XB9's with 1050 kits and stage 3 heads. I would expect low to mid-90's for hp, upper 70's to low 80's for tq. |

Terry (Buelldynoguy?) got 100 HP just from a Micron and re-tuned ECM. |

You probably ought to consider cams and re-mapping as part of your expense calculations. Also better valve springs if you're going to be running higher RPM's OK - Slaughter's Suspension Crusade Warning!! Spend your money on suspension upgrades FIRST. You can do so much better everywhere on a bike with predictable handling than on a bike with a few more HP - unless you're only interested in straight line performance (in which case, you probably have the wrong motorcycle) Besides, while suspension improvements will greatly increase your cornering confidence (or speed, if you will) - it will NOT hurt your fuel mileage or engine reliability. (sorry about the rant) |

"Terry (Buelldynoguy?) got 100 HP just from a Micron and re-tuned ECM." that was on a 12 though wasnt it? thats about what we were getting from them at the shoot out atleast. Terry(he had to leave early) and Al pulled right about 94 and 74 out of my 9 that same weekend on the same dyno with my SS Drummer. although that was 8+ hours of dyno time on my bike too. |

hmm, well we knew there was still a little room for improvement yet i guess anyway. we just ran out of time. Al had to make it to the airport so he could catch his plane home. |

Time was the enemy of the shoot out, that's for sure. Too bad too, I'm sure a lot more could have been done. Speaking of shoot out, here's XB9 with the Micron.

Al even said his dyno was reading high if I recall correctly. According to that shootout, an XB12 with a Spec OPS pipe and an open airbox was supposed to make 101hp at the wheel. I have this exact setup with American Sport Bike's ECM map, and on Liberty's dyno I pulled 85hp. I gotta chalk it up to variance in the dyno's. |

Don't get too wrapped up in peak numbers guys, unless they are drawn on the same dyno on the same day. Look for nice smooth curves without nasty dips in them (especially in the mid-range. The dyno run glitch posted has one of those dips in torque from 3500-5000 rpm. It's not a really deep hole, but you'd feel it on the bike. Look for nice steady air:fuel ratios too. While top end numbers are fun to brag about you can't ride your dyno sheet so take it with a grain of salt. |

i know dyno's very from place to place that is correct, but i know kevins drummer on a 12 pulled very close to what he had gotten from it on a few dyno's previously, so i dont think it was ALL that far off! |

This is similar to Slaughter's viewpoint: Spend your cash on more track days. There's much more speed to be found with the person sitting on the seat than speed coming from engine upgrades. But, 16hp on top plus about 10 lb-ft more low end torque, for $800 with the Micron? That's cheaper than going with more displacement. I'm looking at the exhaust shootout results for this info. |

don't forget the cost of the direct link stuff to make the Micron run right and put out those kinds of numbers. And yes, the dyno for the shoot out was a little on the "happy" side. Doesn't matter, the Micron and DL set up is sweet. |

For a twelve though the Micron and Drummer seem to be VERY competitive with each other. From what I've noticed the Drummer has a hair more across the low end and the Micron has a hair more across upper end. |

M1, I've got to agree. |
