Title: Best $100 performance upgrade Post by littlefights on 07/12/10 at 07:12:53 I've got a little extra cash and a long weekend coming up, so I'm looking for the best $100 performance upgrade project that can be completed in that time frame. I've got an '86 Savage with an Emgo muffler and I rejetted at that time - main jet 155, pilot 50 w/ bleed holes. I still have the stock air-box. I recently got new tires and have a 140/90-15 rear. I was considering either taking out the air-box and switching to a cone or a chain conversion. Or whatever other ideas anyone has to offer! I'm basically looking for a little more grunt off the line and maybe a bit higher top-end for around town, but I don't do any highway riding so a comfortable cruising speed of 70mph isn't important. What will the air-box change do for me performance wise (I know I'll likely have to rejet)? I probably need to rejet anyways - since moving to NC I've picked up the backfire again. Is there a good ratio for the chain conversion for what I'm looking for? I've searched and looked through quite a few threads that mention it, but most of them are focused on getting a good cruising speed. What else could I do? I'm open to any and all ideas! And as always, I'm grateful for the help. This forum is an amazing resource. |

Title: Re: Best $100 performance upgrade Post by Phelonius on 07/12/10 at 09:06:48 If it is off the line you want, I would go with the chain conversion. 16X 50 was what I used to pull a sidecar with. It is only a small bit lower ratio than the belt. 16X52 would give a more noticeable acceleration but you might not like the loss of top end. Phelonius |

Title: Re: Best $100 performance upgrade Post by Hashbrown on 07/12/10 at 09:25:55 you may not even have to rejet with the new air filter if your already running a 155 main jet although a 50 pilot seems a bit small, prob just retune the mixture screw in the carb. most people say you dont see a noticable difference in the airfilter change but i def did. bike takes nice deep breaths now. may get a few more hp out of it but ill tell you what, you will def hear a noticable difference in the sound. she's gonna growl at you ;D Also the cone looks way cooler then that rubber boot |

Title: Re: Best $100 performance upgrade Post by bill67 on 07/12/10 at 09:28:51 I would think you will lose a little bit of low end with a more open filter. |

it doesn't as long as the low speed circuit of the carb is set correctly to suit the new air filter you will have more low end :) |

Title: Re: Best $100 performance upgrade Post by Routy on 07/12/10 at 10:30:25 Think ! If a filter was giving any restriction whatsoever at low and midrange RPM, it would be pouring out black smoke and choking to death at WOT. That is a no brainer.....IMO. Therefore, if you see any increased performance using a less restrictive air filter, (or even no filter at all) it will be at WOT only. This is the case w/ any engine, not just this one. |

Title: Re: Best $100 performance upgrade Post by ArGaT on 07/12/10 at 11:41:57 Sorry guys im not up to date with the acronyms, LoL dont even know if i spelt it right... what does WOT mean please? Also what would a rejet cost and why would i do it also what benifits would i get from doing it please? |

Title: Re: Best $100 performance upgrade Post by justin_o_guy2 on 07/12/10 at 11:51:01 WOT are you talkin about? WOT = WFO, Wide open throttle. he he he, |

Title: Re: Best $100 performance upgrade Post by Routy on 07/12/10 at 13:22:50 You are not going to gain anything by rejetting if it doesn't need rejetting. Some bikes need it, some don't. There are several ways to tell if its running rich or lean. Checking the spark plug color is one. Checking performance is another. If when pulling the choke at a given speed, the engine speeds up, then it is running lean, but maybe only at that given speed, which specifies which circuit in the carb needs it,.....not all of them. In my case, raising the main jet metering rod .050 fixed it right up perfectly. Opening up the exhaust can cause a need to richen up the main jet circuit,.....but if operated at higher altitude, it may not even need that. IMO, just an air filter mod/change would never be cause to rejet. As a rule, these bikes come from the factory jetted on the lean side. Some are a problem, some are not. IMO, if its running good at all speeds, don't rejet. 5162577144100 wrote:

Title: Re: Best $100 performance upgrade Post by littlefights on 07/12/10 at 13:40:58 Oooh, I hadn't thought about a fork brace. That is a strong contender. Its not that I really need anymore power - she's got more than enough for fun riding, so better handling may be the ticket. Phelonius, what does the 16x50 do at getting-around-slow-car speeds - say 30-40mph? Does it make a big difference compared to the belt? How much of the top end would I lose? The previous owner did the white spacer mod and messed with the mixture screw. I've never touched it since rejetting after the exhaust mod fixed things, so I'll have to give that a try. |

Title: Re: Best $100 performance upgrade Post by james may on 07/12/10 at 18:43:00 Id go for the fork brace. For performance the only time I would think lowering your gear ratio would help would be first. After that just wait longer before you shift for similar performance gains. Of course there aren't any good projects. Brace could take an hour if you have to take the forks out to put it in. Air filter maybe half hour and only cost 20$ if you rejet, 8 if you don't need to rejet. For real performance. I'd look into either dropping in a bigger cylinder or a performance cam, but those are more like 200-300$. |

Title: Re: Best $100 performance upgrade Post by Skid Mark on 07/12/10 at 19:14:23 A fork brace made a huge difference in handling on my S40. Less twitchy at hiway speeds and a lot more stable when handling ruts etc. The bonus is that it's real easy to install. If you don't need more engine performance, I'd say the fork bracemshould be on your short list. |

Title: Re: Best $100 performance upgrade Post by littlefights on 07/12/10 at 19:14:57 With this heat wave, I won't be too disappointed if I can get the project done in a couple of hours. I've got a few others things I'm going to do at the same time, too. Relube the axles - didn't do a good enough job when I changed the tires, pull the passenger foot rests, and depending on how much I end up spending on the performance project, removing the rear-fender rails and installing new turn signals, maybe a new taillight. |

Makes a huge difference. & I dont care what anyone thinks about how I look, Im the one living this life & when its my turn to die, no ones gonna do THAT for me, so Im not about to let some schmucks opinion ( or have any fear of that opinion) to change how I live it. |

Title: Re: Best $100 performance upgrade Post by mornhm - FSO on 07/13/10 at 07:21:57 Something to consider is the definition of performance. If you define it by something that makes your Savage perform tasks that it couldn't before, thus giving you an excuse to ride on errands (grocery, drug, hardware, convenience store etc) then for my money, a big tank bag, luggage rack or a trunk is an absolute necessity and one of the best performance upgrades you can get. |

How much does it really help, and how? BTW, says 10 minute install, 2 beer job? Do you shotgun one before you start?? haha :) |

Title: Re: Best $100 performance upgrade Post by bill67 on 07/13/10 at 12:22:24 I bought one and put it on right away so I can't say how much it helps the S40,I had them on 2 other bikes they help,Most of my bikes didn't have them and I never missed them.In fact I went 30 years without them. |

Title: Re: Best $100 performance upgrade Post by Skid Mark on 07/13/10 at 17:53:54 I got the Tkat. Works well and is a bit less expensive. I ran the bike 1 year without and installed it for the next season. It made a bike difference. A lot more stable with the fork brace. |

Title: Re: Best $100 performance upgrade Post by wolfmrp on 07/14/10 at 10:33:22 I noticed a big difference riding at highway speeds after installing the superbrace. If you do mostly town riding it may not be worth it, but if you spend a good amount of time over 55mph you may want to consider it. Oh and it is more like a half a beer install. ;) |
|
Title: Re: Best $100 performance upgrade Post by littlefights on 07/14/10 at 16:44:13 After doing some more poking around, I'm pretty sure I'm not going to do the air-filter mod. I'm leaning towards the fork brace, but am hoping some other people can weigh in - does it make a significant difference on surface roads around town? Or is mainly a higher-speed thing like wolf says? |
|
Title: Re: Best $100 performance upgrade Post by Skid Mark on 07/14/10 at 17:35:11 I found it helped when going over ruts at slow speed |

Title: Re: Best $100 performance upgrade Post by ero4444 on 07/14/10 at 17:48:54 My Tkat brace makes handling on grooved road, wander around less. Very easy install. I haven't noticed any other differences in handling but I'm kinda new rider. Looks OK too but not as pretty as Superbrace. The Tkat is almost half the price. |

Title: Re: Best $100 performance upgrade Post by bill67 on 07/14/10 at 18:53:31 The superbrace $139 95 at I- Bike |

Gotta get the bug deflectors off, I had to do some grinding under the brace, b/c it was just too close to the fender. Looked like it was gonna slowly eat the paint. Instructions say to check forks & make sure the brace doesnt cat6ch them just a bit "off center" & hold them there. I do stuff Ive never done before slowly & carefully, even if it looks real straightforward & easy. & I drink my beer at a reasonable p-ace, too.. |

Title: Re: Best $100 performance upgrade Post by JohnBoy on 07/18/10 at 05:25:31 Before you mod the carb... I am running a stright pipe and an open filter, I have a 150 main a 55 pilot and the white spacer is at 1/2 thickness. But, It failed emissions testing in AZ for being too rich. Does it start and run better? Yes. Is the plug showing overly rick? No. Does it perform better? Yes. I still get 100-115 miles to a tank before reserve. Now I get to pull the carb, put the old jets back in, pass the test, and put it back the way it is...all in 115 heat! If your state requires inspection try to get your tag updated in the winter :) |
