Title: se muffler mod Post by jd06s40 on 03/26/07 at 17:19:16 i have a 06 s40 at 941ft altitude what main jet and pilot jet will i need for this mod and not have backfire and popping thanks in advanced

Title: Re: se muffler mod Post by barry68v10 on 03/26/07 at 17:41:23 Personally, I would start with the white spacer mod before changing any jets.  1/2 white spacer should solve most, if not all, of your woes.  Then proceed with Lancers carb tuning found by a site search.

What kind of riding do you do?? Are you a commuter with city road travel?? A highway traveller?? The more you contribute the more responses you get. BTW, you will always have a few pops on decel. Its just the nature of the thumper. Its the real backfires and a very lean fuel system you should be intrested in eliminating . check my sig line. I ride at near sea level in the deep south.

Your needle jet 1/4-3/4 throttle and your pilot jet closed to 1/4 throttle. Bearing that in mind what part of the throttle are you using the most??In my experience if you change the exhaust you should balance it with a change in the intake. either a better freer filter or a desnorkel or both. I would also suggest the iridium plug. When you get ready to adjust the air screw please refer to lancers straight and simple carb tuning in the tech forum. It works. the jets are trial and error. They are cheap. I have a 55 pilot on my work bench. If you would like to try it, PM me an addy and I'll send it to you. If you are having backfire on upshift its more than likely an air leak. Either in the intake or exhaust. check your connections and pay attention to the header connection. You may want to pull the header gasket and make sure it is not cracked or deformed. backfires on decel indicate a lean fuel condition and are remdied by rejetting. hope that helps.

I need a 55 pilot jet if you like to get rid of it still. You can PM me if so.

Title: Re: se muffler mod Post by jd06s40 on 03/27/07 at 17:14:31 took the bike out today after putting 152.5 main jet in and adjusting mix screw and it ran great on day put about 80 miles on it. went to dealer and picked up 55 pilot havent installed yet cause bike ran so great today. think i should put the pilot in?

Title: Re: se muffler mod Post by Reelthing on 03/27/07 at 21:32:45 How many turns out are you on the pilot/mixture screw? If ~2 or so I'd leave the pilot jet as is

Title: Re: se muffler mod Post by jd06s40 on 03/28/07 at 16:41:05 about 2 to 2 1/2

Title: Re: se muffler mod Post by Brewbrother on 03/29/07 at 19:32:52 jd06s40 wrote: about 2 to 2 1/2 then you need a rejet. Go bigger on the pilot and shave the spacer. I will not recomment getting rid of the spacer although I do not use one. Your altitude is the variable. how high is ohio??
