I have a 2004 Suzuki Twin Peaks 700 with 700 miles on it. When decelerating after maintaining a constant speed for a few minutes, it backfires really loudly. This is worse in a downhill deceleration. My local dealer always says "cannot reproduce" because they only test drive in their parking lot. Does anyone have any suggestions?

Another problem that I have is that the right front tire is showing excessive wear. I took it to the dealer and they said "Alignment checks out." When I quizzed them about this, they said they checked it with a string. Is this truly how you check the alignment? Even a casual observer can see that the wheel tilts out from the bottom to the top.

I will certainly appreciate any help anyone can offer on these issues.

Do you have an exhaust on it? Airbox lid off? Aftermarket filter? Any mods at all? You prolly need to change your jets to match your altitude to fix your backfiring problem. Guarantee ya thats the problem. They come lean from factory to meet restricitions and all that crap. Doesn't sound like your dealer is very.....well, I wouldn't like them. lol


Few probems that could be wrong with that front tire.
1. Frame may be bent....crashed any lately?
2. Your rim may be bent....I'd say thats the problem most likely.
3. Or your alignment IS off.....

Have you crashed any lately? Hit that tire real hard? Maybe its your tierod or A-arm thats bent. Need more info...and I could possibly narrow this down.

No add ons. Strictly stock. I was also thinking it is running too lean, but dealer says it is fine.

On the front end, the dealer said they checked it with a string and the alignment is fine. Do you know what this "string" thing is?

No crashes. I am old and ride conservatively.

What I need is info that I can use to argue with the dealer. They have the unit, as I refused to pick it up after the told me the alignment was fine in face of the tire that is balding on one side and fine on the other.

Can't change dealers, as they are the only Suzuki dealer in town.

Appreciate any help

No clue about that string thing, I have never had to check my alignment. Maybe your rim is bent or alignment is off. Only thing I can think of.


Jetting is your problem I'd say, it probably isn't matching your altitude, but it might be matching the dealers altitude.

Welcome to the site Colvja. Sounds like your dealer isn't interested in getting to the bottom of the problems you're having. You might check for proper air pressure to start with. And actually, if you know what you're doing, you can do an alignment check with a strong non-stretchy string. Toe in and toe out in particular. If you know what factory specs are it's not hard to measure center line to center line front and back on your front tires and see if they're where they need to be. We used to do a lot of that back in the day, but not so much anymore..
