My bike backfires terrible -- can't seem to get rid of it. Tired of spending money on it -- still not fixed. Can anyone help?

There's a few things that can be done. Going with the cheapest first.
1. Highest test gas.
2. Hotter spark plug.
3. Carburetor adjustments.
4. The best results for this bike (Savage) are with an after market pipe.
If none of the above work, you need a new mechanic or bike. But one of the above will work; if not, do like I did for my 03 Savage, all of the above.
Still have my bike and love it!!! Food for thought, install a kick ass stereo on your bike.
Smile, have a great ride. Bob.

I have 1400 miles on my S40, and the backfiring is one of best thing about the bike.
If you really want to get ride of the backfire, change the muffler and run higher octane gas.

You don't need high octane. You need to richen the carb by adjusting the air mix screw on the right side of the carb in about mid way up. Very small screw with possibly a brass plug covering it. Be very careful with it, 3 turns out max! The threads will strip if you go tearing in there.
For real details, go to www.suzukisavage.com and search for air mix screw.

I am a new owner of an '86 Savage and love it.
One mystifying thing is that when I throttle off, there is a whirring, rubbing noise - I've checked belt tension, looked for pulley wear, without result. Any ideas?

The noise you're hearing could be the upper cam and the clutch plates. The bike itself is really simple to work on, but if the whirling noise turns into a tapping noise, stop riding as soon as you hear it. DO NOT RIDE WITH AN ENGINE TAP, it'll kill your bike. Try using a synthetic oil additive to your regular oil, and listen for any changes.

I have a 2004 LS 650 Savage. I installed a Dyno Jet Kit in the carburetor and an after market 16" turn out exhaust from J. C. Whitney.
Result: The LS 650 Savage came alive with power and response. However, the fuel mileage dropped to 40mpg. This bike will give the big bikes a run for the money. Also, since I installed the dyno jet kit and opened the idle screw 1/2 turn, I have never needed to use the choke to start the bike and the biggest plus is, the back-fire has gone.
I hope this helps someone.

I just purchased a 2003 Savage without a manual that I like very much. I have to change the oil, anyone know how? And I also have a hammering sound on acceleration. I've been told that if I change the oil, and put some Sea Foam in and ride, that it will probably be corrected.
Any help out there or related incidents? Thanks.

I have a 2003 Savage that is electrically dead, no lights, no turn signals, nothing.
I'd like to know if anyone out there knows where the main fuse if located, before I pull the tank off and find out it isn't under there.
Any ideas?

I have an 04. If you remove the main driving seat (1 bolt on each side underneath), you will see about 6 wires running into a white plastic square... remove the cover on the white plastic square, and you should see 2 fuses. Check them both. Hope this helps.

Turn down the idle, just enough to keep it easily running when the engine is hot. That will do it.

Also on the Jan 21st comment:
You can also check the rectifier under the seat, and make sure it isn't getting too hot. If it is, they are very easy to move. I relocated mine to the tool box, and mounted it in there. Much more air flow gets to it now, than when under the seat. Plus, I have saddlebags thrown under the passenger seat, making the rectifier move mandatory.

Try turning the bracket that holds the muffler pipe to the block. May be upside down, or the bolts may be reversed. That's what I found out with my bike.

Thanks for the tip. I pulled my spark plug; it was a nice brown, which eliminated the carb. I have been using the factory recommended plug. Every time I turn off the machine, I have been getting a big bang. It was as simple as going to a medium grade fuel and turning the idle down. Now it shuts right down. I have a 2007 S40 with 1200 miles.

I bought a 2007 S40 recently with almost 37,000 miles on the clock. It backfires, especially before it's fully warmed up. However, I don't think I'll mess with it - it's hard to argue with 37K miles.

If you want a sissy bar, you can order the parts for a pre-2004 LS650 from a dealer (don't know if the mounting to fender is identical). Or place an ad. A lot of people have modified their LS650 to eliminate the bracket and turn signals (and the rear seat) altogether.
