Backfiring, poor gas mileage, slew of other things
06/01/09 at 06:11:18
I've had my savage for about two years now, and after I brought it out of storage this spring I've had some trouble with it.
The exhaust smells extremely oily, the bike backfires almost every time I roll off the throttle, the bike won't start below 50 degrees, the bike won't start with the choke on, the bike has trouble with any speed above 70mph, and I'm getting less than 35 mpg.
I think the problem is the fuel mixture, but to my understanding to change that I'll need to drill out the brass plug for the carb, and that make me rather nervous.
the problem here is that my savage is my only means of transportation, and I use it everyday (regardless of weather) to get to and from work. So I can't really screw things up and have it out of commission.
any advice? should I just go for it and try to adjust the carbs myself? should I take it to a dealer over a weekend and have them tune it up (it is up for inspection soon...)?
Thanks!

Put some Sea-Foam in your gas It might fix it.

The Seafoam is unlikely to help. What will do the job is the fresh gasoline you put in the tank along with it. That fresh gas will flush the carburetor as it runs through. If the bike runs better, you'll give credit to the Seafoam. If not, you'll just think the carburetor was too dirty. Kind of like prayer - if your prayer is answered God gets the credit. If your prayer isn't answered, you take the blame for not believing fervently enough.

while you may (or may not) have a point about the seafoam, i've had about half a dozen new tanks of gas in my bike with no change. Even tried premium for two of them in a row to see if that would help (it didn't)...
I'm thinking tonight i'll take out the spark plug to see if it is fouled up, and if it is clean it, but i don't think a bad spark plug would cause all this.

The Sea Foam is the answer.Works 99.9 percent of the time.

You can always try Seafoam, or any of a dozen other miracle additives. It might work, and at least probably will do no harm. I suggest you Google "seafoam msds" and find out what you are actually getting. I point out that, by Federal rule, ALL gasoline is required to have a cleaning agent added to it, to keep carburetors, injectors, and intake valves clean.

Space:
If the bike was running fine before storage but not now, sounds like a fuel/firing problem which could be explained by a fouled plug, or a gunked up carb. Unless you did a muffler mod or air intake mod, the idle mix screw would not all of a sudden need to be adjusted. (Although the Savage does come from the factory White-spacer mod ready!). As far as drilling out the brass plug, BELIEVE ME it is a very simple mod, and I heard even a teacher can do it! Try the SeaFoam to get it back to its previous performance level, then jump on that White Spacer mod to make it even better. Changing the spark plug is no biggie either, but if you haven't already you'll want to do the Spark plug door mod as well to make it easier to change. Check the Index of the Tech/Reference section for instructions on how to do these mods.
Good Luck, and Go For It!!!

I'd dump the gas for fresh, change the plug and try the seafoam. Most likely gunked up from sitting so long

bill67: As I have said before in other threads, I have never used Seafoam. I have never needed it. I have looked up the ingredients. There in nothing in it that I can see which would make any difference. I don't remember saying it doesn't work, but I have said I don't believe it works. If I wanted to clean a carburetor, or other fuel system, I'd look for a solvent, not an oil. Remember that gasoline is a pretty powerful solvent all by itself, and if it has ethanol in it, ethanol is another pretty powerful solvent. You are going to have a tough time finding solvents more powerful which will not damage the very system you are trying to clean. You are free to believe Seafoam works, and espouse its use. I am equally free to believe differently.

Well, like i said, I've had about 6 fresh/new tanks of gas in the bike, two of which were premium grade.
as for the seafoam, i'm finding about 60% of people love it and think it works miracles and the rest think it is bogus. however, at a couple bucks a bottle, and no consequences of trying it, I think that will be my first move before I try and pull apart my carb and muck around inside it.
Up here in the 'Burgh, we don't have Clark gas stations, so no worries about that. I typically use Shell or Sunoco when I can (but i'm not looking for wars here about what gas is better than what) but I'll use whatever if I'm in a pinch (in the middle of no where and been on the reserve for a dozen miles or so...).

whur y'at? Split a 6 pack of pabst pounders with me and i'll clean the carb myself. Unless it super super bad I'll have it out cleaned and reinstalled in little more than an hour. Im practically pro at it now after rejetting. I live in Penn Hills. Ineclipse lives in Polish Hill. Once his collar bone heals up we can all ride together. Also...check your airbox and make sure nothing crawled in and nested in there while you had it in storage.
