Title: Re: Lancer Upgrade Post by lancer on 09/12/05 at 09:05:05 Installation complete. This was taken on Saturday. On Sunday I went on the March of Dimes Ride, which was a lot of fun. I am a new memeber of the Southern Cruisers mc club and rode with them for this ride. I met a lot of good folks and am looking forward to a lot more of these rides. This club is linked to several others in this area of the state and they have stuff going on all the time. I receive emails several times per week about the activities that are coming up, and with the different clubs all linked together everyone gets the info from everyone else. I like it. The complete bike.......... http://images.snapfish.com/3449769523232%7Ffp47%3Dot%3E232%3B%3D72%3A%3D788%3DXROQDF%3E2323%3A%3A655768%3Aot1lsi After the ride was over, on my way home...actually about 1/4 mile from the house the muffler hits the pavement......grinding sounds...............not good.......... The weld at the front end of the muffler did not hold. BUMMER!!!!!!!!!!! The surprising thing was that after I removed the muffler in order to ride to the house (got to get the car and go back to pick up the muffler....that sucker was hot! Burned the green grass dead). Anyway, with just the header and no muffler, the bike ran great. It had been running rich all day. I had put an Edelbrock Quicksilver on it for the days ride but was not able to lean it out enough...needed a different needle. So it had been running rich in the low and high range, but good in the midrange. After the muffler was off, and just the header, the engine loved it...ran much better and the sound was just AWESOME!!! So now I need to work out a new attachement for the Supertrapp...I will leave the discs off the next time and run with just the open muffler . The Amal goes back on until I can get some new needles for the Edelbrock. |

Title: Re: Lancer Upgrade Post by Greg_650 on 09/24/05 at 10:33:11 BTW - since you aren't using the muffler bracket with your SuperTrapp, you can completely remove it from the frame. Might clean up that area even more if you do...just a thought. Here is what I did to mine for the Raask pipe. http://i21.photobucket.com/albums/b277/gmdinusa/MufflerBracket01web.jpg |

Title: Re: Lancer Upgrade Post by verslagen1 on 02/02/09 at 19:30:01 You got them seats filled with helium? Or is that a 12" shock? Most people lower the front end when they want sport bike stearing. ;D |

Title: Re: Lancer Upgrade Post by diamond jim on 04/03/09 at 08:54:19 Edlebrock Quicksilver? Is that similar to the Carters? Does it have the adjustable jetting? http://i255.photobucket.com/albums/hh128/russ_diamond_jim/34497695232327Ffp473Dot3E2323B3D723.jpg Also, your intake setup in this pic has perked my interest. How do you have it set up? |

Title: Re: Lancer Upgrade Post by srinath on 04/13/09 at 07:21:36 Muffler - broke @ the weld. Please tell me you didn't mount the exhaust on the swingarm ... I couldn't tell from the pics ... the swingarm ... its ... well a swingarm, it swings ... you have to fit it back on to that stock carrier you lopped off. Like make a cradle or somehting ... Cool.

I cant see your pic, but I thought that muffler carrier also carries the rear motor mount and the battery box. Cool. Srinath. |

Title: Re: Lancer Upgrade Post by AngloSaxon on 05/21/09 at 09:00:02 I cant believe you mounted the muffle on the swinging arm. It just goes to show that even the best of us are fallible. Rock on Bro. |

Title: Re: Lancer Upgrade Post by mikestrikes on 05/21/09 at 09:44:04 What size tube did you use to build that header ? |

I bought basic tube that was 1.75" OD and 1.6" ID. The assorted pieces I got were swagged on one end so they would slide into each other at the points I wanted. Kind of a "cut & paste" type of thing. I managed to weld it up so it stayed together and does not leak. I tried to do another but was unable to repeat my earlier work. Not sure if it was just me screwing up, or the inexpensive welder not performing well, or some combo effect, but it was a no-go. At least the first one does work well. I hope to try again in a few weeks...we shall see. The 1.6" ID works very well with a modified engine and high flow exhaust. If you have a stock engine I would suggest using 1.5" ID pipe and a Dyna muffler at least, or Supertrapp, etc, for the good flow. When I measured the ID of the stock header I got 1.3" ID on the inner pipe. |

Title: Re: Lancer Upgrade Post by mikestrikes on 05/21/09 at 17:10:39 Thanks. I was going to use 1.5" for the first bend out of the motor and 1.75" the rest of the way to the muffler.. |

Title: Re: Lancer Upgrade Post by LANCER on 05/22/09 at 05:09:03 The header on a Savage is only about 30-33" in most cases, unless you go unusually long. If your engine is stock you will get better all around performance out of a 1.5"ID pipe, especially if you have a high flow muffler on the end. Going longer on the header may add some low-midrange torque even if you do go with the bigger tube. I just made arrangements to get on old 87 model with a stock engine and will try to make another header but will be using the 1.5"ID pipe for it. As soon as it is running I will do some jetting tests with stock carb and header; I think it has a dyna muffler on it now but am not sure. After that is done then I hope to do the new pipe with same stock carb and same muffler and just rejet/tune to suite the engine with the new header and see what the differences are. Hopefully, I can document the process on a local dyno...subject to funding of course which is always an issue. KLX does this stuff for a living over in England and if he comes around this thread maybe he can throw in some professional wisdom. |

Title: Re: Lancer Upgrade Post by verslagen1 on 08/07/09 at 08:59:35 You've menstioned it before but not here... You've had Silican Carbide cylinder treatment aka Nikasil done to Ol' Rex. I've been searching for Phelonius Piston and doing this cylinder treatment. Lukes Racing offers the service and the piston Luke says "IF the bore is cast iron then the charge for replating and boring is $230. The piston kit is $143. 4597M09500 is standard bore." Luke offers free shipping (over $50) and there's only a couple of shops that do the Nikasil thing. For those of you near PA, seems reasonable. |

Title: Re: Lancer Upgrade Post by Duane on 08/07/09 at 12:19:53 Those stilt shocks make it look like a dirt bike. ;D |

Title: Re: Lancer Upgrade Post by LANCER on 08/08/09 at 05:11:52 I would really like to put the new 97mm piston I just got into REX but I will need to send a spare cylinder & the piston to Bore-tech for the rebore and silicone carbide, but money is short right now so will have to wait a bit. At least the engine was not damaged by the engine stop event just before the Dragon ride. |

It did make it look high but the extra travel of the shocks and the quality of the shock effect is just great. During the rebuild of REX I tried to mount the new fender to minimize the tire-to-fender space so it did not look quite as high. The replacement front forks I put on also jacked up the front a little so the whole bike is taller. I may alter the mounting of the bars so I can slide the tubes up through the triple trees, resulting in a lowering of the front. Will see how it goes when I can get back to working on it. I have been having a difficult time the past couple of weeks with chronic physical issues which slows everything down. Such is life. |
