Title: Carburetor JETTING Question
Post by autoxbot on 08/15/08 at 11:10:03

Hi guys/gals, I have a '97 Savage with 11K miles. The previous owner had a stock muffler, but drilled a secondary hole into it. I've recently bought a "slip-on" Dyna muffler from Ebay and Lance's Jetset and cone style Air filter. I've installed the Dyna muffler and getting backfire everytime I decelerate. This was the same case with the stock muffler on. I don't know if the previous owner did any kind of jetting to carburetor.

My question is, do I need to take apart the motorcycle (seat, gas tank off, etc.) to rejet? Looking at the bike, I can see there's no obstruction from me getting to the bottom bow of the carb. Can I just screw out the four screws from the bottom bowl and replace them with the higher jets from Lance's set. Or do I need disassemble everything? I've called a local motorycle shop about installing the cone style air filter and rejetting and they quoted me 2 hours minimum for the job (they charge $80/hr.). How long is this kind of job realistically for a motorcycle mechanic and a wannabe shade tree mechanic like myself?

Lance's Jetset comes with a 55 pilot, and 3 different main jets - 150, 152.5, 155. Wanted to find out what jets to use, if for the moment, I only have the Dyna muffler installed.

Thanks for all the help,

Mark

Like Bill says , 4 screws on fuel bowel (bottom of carb). You may need to push on the battery box a little to get the bowel to come down. Then the main and pilot jets are there. Look in the Tech / ref section for pictures.

I would think to start at 152.5 main.

Note, the jets have numbs on them, so you can see what was in there and go from there. (note: real real real small numbers on the pilot jet..... did I say enough real's there??)

Thanks for the info guys, this is good news. I'll be doing it myself then instead of getting ripped by the local repair shop. Also I wanted to find out which one is the air/fuel mixture screw? The idle screw is on the left hand side of the carb. And on the right hand side, I saw a hole that has a "plug cover" and some kind of slide lock washer on it. Is the air/fuel mixture screw there or somewhere else?

Thanks again guys!!

This is in the Tech ref section. Note: one of the always on top topics is an index. It's real handy.

Picture courtsey of Savage_Greg. Greg, thanks again, and sorry you're so busy.....

It's not real hard to take off the tank, etc and get the carb all the way out - while its out you can clean it a bit and its good practice because you'll want to get the tank of later to check the spark plug when adjusting the carb - I did the plug "door" mod so I can get to the plug to check it without taking the tank off. Dissasembly is not as difficult as you might think - it may even be easier than trying to do it all with the carb in - I took out the battery box too. (installed a battery tender pigtail because I often leave my key in P by mistake)

I also put on the dyna muffler and rejetted with the 152.5 main - your gonna love the difference!

I did my rejet without removing the tank, but removed the battery box instead. I feel it is easier than dealing with the tank. You'll probably want to remove the carb instead of trying to do this in place. I had drill out 3 of the screws plus one of the jets, because they are just too soft. If I did a rejet so can you, screw the stealerships! :D

I just unscrewed the bowl, pushed back on the battery box a little, and dropped her right off of there. Swap the jet and put the bowl right back on.

I think Suzuki must have used better screws and bolts early on. I haven't stripped one anywhere on my bike yet. I'm not talented enough for that to be my fault.

Hello all!
I just bought a 2006 S40 with 730 miles on Sat. I have been riding a 250 Rebel for 10 years and am extremey pleased with the S40. I have read almost all the posts on this forum and because of them I bought a Dyna muff, Jetset (from Lancer), and a bike computer. I am waiting to receive the muffler and Jetset.
I feel I am pretty mechanicly inclined, but I have never messed with carborator. My biggest concern is that I will mess something up while changing out the jets. I have not opened up the carborator yet so all I have to go on is the pics in the tech section. I have looked all over this forum and found vague instructions on performing this task. I was hoping some one could give me detailed step-by-step instructions so I will know exactly what to do and not just hope i am doing it right, or if instuctions are posted somewhere please let me know.

Thanks
