Pammy, Being up here in the great white north in the middle of the winter (see the curse & rant thread for more details) I am planning on the thunderstorm heads with no other work for my S1. What else can I do to come close to the 100rwhp mark without going absolutely crazy. |

Just don't bore cylinders past the factory overbore limit. It'll lead to premature cylinder warpage. So, don't go over 0.030" |

Newfie, sorry I didn't see your question. Heads,cams,exhaust and a carb should get you there for sure. Keep in mind things have to be set up properly for everything to work as it should. |

I contacted Aerocharger today regarding my S2's apparent ability to change fuel pressure without my input, ungrateful bike. Apparently the fuel pressure regulator they used on my model is a Mallory, not sure about that spelling, 4-port and it should be available from JEGG's. The seats were out in them through use of high octane "race gas" and through the use of some octane boosters - I was told. Boo dude! |

Yeah Mallory is sold through Jegs and Summit Racing but knowing that you can figure out the specs and change brands if you'd like. Do you have a p/n? |

Pete ,Roc Sent my turbo to Aerocharger,Dallas Texas for a rebuild. They said they would take care of it but were not ready to work on it yet. They had some military work to finish up on first. |

Roc, You'll be way ahead of the game if you use a Peterson (red) regulator.They don't last forever,but they work well.I find they are a lot better than the Mallory units.We lost one on Jim Dye's S-2 during Bike Week so we didn't get on the board.That one had 14,000 mi. on it.The week before he made 176.3 with only 16 lbs.of boost.We figured on 207-211 hp.with the boost that we use in shootouts.

So, I took the regulator apart and I don't see anything that could explain the variation in fuel pressure that I am seeing. It is a Mallory 4309. It consists of a rubber diaphragm that adjusts the opening to the fuel return line based on input from a control line, which is run off of the plenum. A spring and an adjustment screw set fuel pressure at the base line/idle level. The seat, which I believe Aerocharger told me was prone to wear due to fuel, is aluminum to aluminum. It is visually worn, but you can't feel the wear with a finger or finger nail, and it does not appear to require a precision fit. Also, if it were worn it does not seem that it would swing in pressure regulation, it would be more or less pressure and you could tune it out. All problems I’ve had with fuel pressure have been resolved by adjusting the pressure regulator. Turn in, turn out, adjust again, and I’m on my way home. That leads me to think that it is the regulator. Could be crap in the gas. Could be the fuel pump. Could be a kink in the control line, although I seriously doubt that. Fuel pressure will adjust itself from 2 PSI to 6 PSI by itself. It will also adjust itself down to 0 PSI and act as though the fuel supply is totally obstructed, die on the side of the road. However, both of these problems are corrected by an adjustment of the regulator. Maybe there is a compound problem: bad pump,bad regulator, crap in the gas etc. I'd like to test a bit more before I spend. Ideas are welcome. |

I agree, sounds like a regulator or pump problem. |

Roc, Is the response line from the plenum to he regulator insulated from heat? I covered all mine in thick fuel line, and it ran significantly better. |

Roc, Whenever I find fuel pressure that's all over the board,like yours,it has always been the pressure regulator.If you have checked your lines,and none are broken or badly kinked replace the regulator with a Peterson like in the picture of the big twin above.Mount it with the dome on top,opposite of what's in the picture.

Jim,Pete,John,Roc,any one of you play around with the boost controller on your Aerocharger.Mine has way too much boost and I want to find some way to dial it down.I took off the controller and took it apart.There was no sign that anyone had screwed with it,just a spring,piston and seals basically.But I am seeing over 15-16 lbs of boost at full throttle and want to be abl to have less at first.TIA. |

Looking at the side where it connects to turbo there are 3 small bolts securing it and on mine there is a small threaded hole,looks like it may be for spring tension as it goes through to spring face,and there is nothing in this hole----anyone have something here or is it just a hole????![controller](http://www.badweatherbikers.com/buell/messages/3842/20472.jpg) |

FMJ, For what it's worth, here's mine.
Bolt is 8-32 NC I haven't pulled the controller apart to look but I *think* it's just a stop. Again I *think* (must pull it apart one day and look) it limits the amount that it can move under boost. Pete |

Pete,thanks.I think this is where my problem lies as this screw will put pressure on spring in controller making it stiffer and limiting boost(again only my theory as Aerocharger not answering yesterday and this morning)That screw is a lot longer than I imagined. |
