The difference to engine response is worth it. FCRs do need correct set up and there is plenty of assistance here for that.

I'm going for it, just waiting for Power Barn to confirm availability. Should be fun! |

 The common thinking is 39's for a stock motor and 41's for a worked motor (or one that will get work). There are those that disagree with this line of thinking and some is just down to personal preference. The 41's give more WOT power through the range and the 39's give more partial throttle response. But the difference in response with either will highlight how much of a bottleneck the stock carbs are. I work on a blueprinted 944 Superlight with hi compression pistons, hotter cams, porting, modified airbox, etc and it runs 39's and feels sensational. I have run similar worked 900/944 motors with 41's and they were sensational. To get the most out of them its good to run an open airbox or pod filters. The K&N DU 0900 filter or RU 0800 or RU 1750 pods work well. The Powerbarn kit comes with a filter and nice velocity stack shaped alloy air box adaptors. The blue velocity stacks are just for pornographic purposes

You should start an FCR thread when you get them. |

He's fallen into the rabbit hole now.

Well, slowly :-) The title I received was endorsed in a way Pennsylvania would not accept so I'm waiting on a new one - should be another 3-5 weeks. The header and pipes are on and the carbs will be here and installed next week. A backorder with K&N caused a delay with Power Barn but Mike kept me updated throughout the process. My local Ducati dealer is doing the carbs - they have a tech who really digs/knows the carb bikes. |

Great to hear its progressing. FCRs have been scarce lately, so I've been sourcing used parts from Japan. Mike is very helpful. |

Ol girl has been stranded, waiting on a title for 3 months now but it should be here soon. My local dealer recently installed the carbs so I'll ride in soon. They claim it runs as it's supposed to but they warned me about the quirks that come with these carbs. I can't wait to get it rolling! I now need to find some simple bar-end mirrors!  |

Looks great. What size carbs did you go with in the end? Did the shop tune the carbs? What quirks were mentioned?
I ask because the carbs are often delivered with inappropriate jetting for size of the carb or for a 900.

Thanks! 39s as Mike @ Power Barn said they are better for torque. I do a lot of city riding with some burb and scarce highway riding. Quirks - more of an on/off experience with a less manageable idle. I'm honestly winging it, so we will see soon! |
