I am heading to Maxton, finally this year. Changes for this trip are a full fairing and nitrous. I ran the fairing last year at Bonneville, but haven't ran it at Maxton yet. The nitrous kit is a NX wet system with 2 nozzles. I plan on starting with a 20hp shot and adding to it if everything holds together. So I will run in APS-PG 1650 and APS-PF 1650. If there is time, I may pull the fairing off. Jeff

The fairing is a XR750TT fairing I bought off Ebay a few years ago. I don't know who made it, but AirTech sell the same thing. The tail section is AirTech. The front fender is a RR1000 replica that I am borrowing. Jeff |

Very cool, keep us posted. If you do not have a fuel pressure safety switch get one, I went lean from fuel line pinch and torched a head in Australia. Not a good place to try and find parts.Good luck. |

I do have a fuel pressure safety switch. Also have a cool NX pressure controlled bottle heater and electronic pressure gauge that I can see during a run. Jeff |

Those are nice, had them too. Make sure you have enough volume--though you need less at Maxton than Bonneville. Did you get colder plugs, non extended tip type, and run tighter gap.Champion makes some nice racing plugs as does NGK. |

Only got 1 run in today because of rain, but went 171.9 on that run. I wanted to try a few more things on gas, but with Saturday shot, I am just going to throw the nitrous at it tomorrow and see how fast it will go. Jeff |

Just got home after a 19 hr drive straight home. Sunday I ran on the bottle. The first run, my goal was my 175 license pass. It ran right on 175. I hit the button in 3rd gear and it pulled hard. 4, 5,6 didn't really. I also missed the shift to 3rd. So my second run I went to the 40hp jets and was ready to give it hell. I had a lot of trouble getting the bike started through...hum This time I waited to hit the button until 4th gear and again it pulled hard at first. I shifted to 5th and it felt like I was out of NOS and when I shifted to 6th, the bike was slowing way down and sounded bad so I shut it off. It wouldn't restart and a compression test back in the pits showed 0 psi on the front and a broken (not melted) spark plug electrode. I probably won't get it torn down, but since there was no big smoke show, I don't think I burnt through the piston. I am speculating that when I missed the shift on run 2 I over reved it and bent a exhaust valve. This made it hard to start and then it gave up on the third run. That's just a guess for now though. The positives - 2-1/2 runs and 2 records. 171.9 and 175.1. And I got my 175 license. Negatives - $ per run was real high and I didn't really get to get a feel for NOS. Now I have until April to think about it some more. JEff |

Ouch, sounds like it might have gone lean. Good luck, been there. |

You just have to run in the same class we do don't ya? If you didn't I could help you with the nitrous issue. (Message edited by buelliedan on November 04, 2008) |

Don't worry, I don't plan on running the NOS at Bonneville. I am just playing with it while I build a new bike. Jeff |
