Hey guys, I have a '98 Savage with 3200 miles. I just bought it last month. It has a Supertrapp exhaust on it. The previous owner said when he had the exhaust put on, he had a new jet kit installed. The pipe is discolored and so is the Supertrapp. The bike backfires on deceleration and when I shut it off.

I hear that removing the white spacer would help, But how do I know if it has been removed or not. Is there a way to tell what jet kit is in it too? I have no idea how to do these things. I am pretty mechanically inclined, but have never worked on a motorcycle.

I was thinking of putting on a Jardine exhaust, should I get a jet kit and have this all done at the same time? Can I do this myself? What jet kit do I need?

I know it's alot of questions and I appreciate the help!

Thanks
Tim

Good luck.

I have a 2001 Savage LS650 and it backfires big time. It's kind of fun, but sometimes annoying. What I want to know is: if I take the white spacer out, should I also put in a #152.5 main jet in or do I do both? I would like to see an increase in power also. And should I replace that spacer with a half size spacer and what is half size?

As someone else said, the Savage backfires. It is known for it. I have the Jardine and didn't rejet and it backfires more. I don't mind it at all. It reminds me I'm riding a Savage. There are some things you can do while riding to decrease the backfiring.

When letting off your throttle, don't let it pop back, slowly let off. This will help tremendously.

Myself, I too find it to be a trait of the bike, it kind of announces that you are there.

Okay, is it an "issue" or a "trait". Don't issues imply a problem?

It is definitely a trait of a stock bike, but it becomes an issue when the jetting needs to be corrected.

No, I mean when the jetting needs to be corrected because the mixture is different than the original factory setting due to other changes to the engine. That's when backfiring is an issue rather than a trait.

Now, Mt. St. Helens has her own backfiring issue, but does seem to be in the process of rejetting Roll Eyes
