I have a Softail '05 with carb and added Se air filter and adding Se double barrel exhaust system. I read a load of posts over the last week, including all the recommendations on Stage I rejett. I was just looking for others who did the same mods and what I need to start with. Stock jetting on my carb is 190/45. I read somewhere to start with 46 slow and add two #4 washers under needle, 2 1/2 turns on the air/fuel mix screw. Is this correct or is there something else to start ? Please help.

Thanks Jim

 

That change sounds reasonable, That main jet sounds alittle big though.

 

I thought so too but it says that in the service manual.

 

Check into the DynoJet Thunderslide. I put one of these on my '96 RK and achieved 15% better mileage and improved performance over the previous Yost Master Tube. The bike now has 108k miles and the only time the carb was touched was to remove it to access the manifold for a seal change. The kit is expensive, $140 IIRC, but if you ride a lot and plan on keepng the bike the savings alone will more than pay for itself. That bike rarely fell below 50mpg, and routinely got in mid-50's on trips in touring mode (WS, Tour Pak, loaded).

If this new SG had a CV carb, I would definitely install another.

 

You want to raise the stock needle about 0.050" with the washers. A better solution is to put in an 88-89 Sportster needle with no shims. Either way you got it covered. I would go 2 1/2 turns out with the 45 slow jet and 2 turns out if you go with the 46 slow jet. If you purchase the needle and 46 jet the whole thing will cost you under $20 and out perform all the aftermarket kits, period.

 

That sportster needle is marked with code : N65C
Partnr : OEM 27094-88

Mount the needle without washers !

 

Thanks for the advice but no extra cash right now.

 

Thanks Mike, I'm torn which way to go when I'm ready either the new needle or washers. Heard good and bad of both.

Jim

 

Thank you, is that what you used was the needle?

Right now I'm running the Sportster needle, 46 slow jet 2 1/4 turns out, and a 190 main. The bike is rich at 12.8 a/f ratio, but it makes good power and runs cool down here in south Texas with the added fuel. Last time on the dyno it made 77.2 hp, 82.5 tq

I had the Dynocrap kit in it for a while. It ran good and gave me around 41 mpg but it lacked the midrange that the current set-up makes. The current set-up made a noticeable difference in the entire range but particularly in the midrange, it runs smoother, and gets better gas mileage. I will lean it out to around 13 - 13.2 when I finish the engine mods that I have planed.
