I had my carbs serviced at a new dealer in town because the 2002 legend wouldn't start. It seemed to run rough so I checked the plugs and found them gapped wrong. They gapped them in thousands instead of metric. This and the fact it took them 3 days to clean the carbs tell me they are kinda clueless.

Now here's my problem, the machine backfires when shutting down and is still hard to start. I called Bombie to see if I could take it to a different dealer to repair under this dealers 90 day warranty and was told I have to deal with them.

What should I do? Forget this dealer and try another or demand this dealer to do the job right?

???

Your dealer sounds scary (although everyone makes mistakes once in a while)

I think if it were me, that I would look for another (as long as you don't have to travel too far).

I like to support my local dealer as much as possible, but if they are out to lunch, then they don't deserve your business. (any mechanic that can't gap plugs properly, would not get anywhere near MY machine!)

You can deal with any dealer you like as long as your machine is under warranty.They should have gapped your plugs properly but I doubt that is whats causing your problems as long as the gap is within reason.(i usually just run them out of the box with no problems).When you say the sled is backfiring when you shut if off,is the sled idling fast and then building up gas in the muffler when you shut it off.This usually results in a big bang out of the exhaust just as the engine stops turning.Or when you restart it will give a big bang out of the exhaust.This can also be caused by a real rich condition.

Might want to check your reeds.

I agree with oldyeller and krusty, check and see if the chokes are
adjusted correctly, you need some free play in the lever.
Backfires are hard on reeds, my 670 use to do this after a long wot
run then quick shut down. ??? ???

It sounds to me like the carbs were not put on proberly and are loose.

This seems like a normal issue with the newer Doo's. All the newer twins do this around here. It actually seems like a lean condition at idle. What I usually do is crack the choke a few times to bring the idle down and let it idle for an extra 30 seconds or so. This usually cures the backfiring or at least makes it so you can live with it. I leaned my carbs out further because the sled was very rich at cruising speed and top end and this made the backfiring a little worse and it is harder to start now. I'll have to play with the carbs some more.

Thanks to all with my question. You guys might not be as good as having a Ski-Doo mechanic as my next door neighbor but you sure are damm close. :p

I plan on taking it back to the dealer who did the work armed with your replies. Wish me luck!

Be sure to let us know what happens.

Hey LB700 what do you mean by "gapping plugs"???





J/K :p

Maybe someone can furnish me a clue. My wifes sled is a 600 MXZ 2001. It prefires one the start up. Usually it seems when the sled is warm. Seems to run OK but it often backfires/prefires (whatever0 on the first pull and then starts.

Is this timing, fuel what? Also maybe unrelated but it smokes a lot on start. Much more than the other sleds (all 2001 MXZs) that she rides with. Although their sleds are 700s.

Any idea where to start checking for issues?

Here's a question. Are you letting them idle down before shutting them off? If you don't it'll backfire at shutdown or start up(as stated above) I let mine idle down to 1800-2000 RPM and let it set there for about 10 seconds before I hit the kill switch.

I cant say that she pays particular attention to how long it idles down before killing it. usually it is something like pulling up to a pump or stopping on the trail to talk. Then when she gives it a pull it fires and starts. same pull . She can try letting it idle for a longer time this Saturday and see what happens. Great tip and others are also welcome.

Gmich,

I noticed in another post you just picked up a 2001 Mxz for your wife. Great sleds. Another common problem is a high idle when you come to a stop after ridding for a while. Next time she comes to a stop have her look at the Tach and see where it is running. A lot of the MXZ's would hold around 3000 Rpms. Sometimes you can blip the gas or flip the choke real quick and they will come back down to 1800 where they should be. If you do shut it down at 3000 Rpms's it will cause the backfiring like you are describing.

Great help, you know now that I think about it the choke came out once and we had to put the lever back together and re-insert in the choke back into the body. Maybe this causes some issue.

Do you know anything about diagnosing heated grips? Her grips seem to get a little warm but nowhere near enough. Could it be the switch itself or the grips?

I replied in your other post about this.

Stupid question ......

Arent spark gaps set in "mils" ...... wich are a standard measurment not metric ? 18 mils = .018"

I have been asking quite a few questions and cant seem to locate your responce. Would you mind repeating it. :bash:

"I have been asking quite a few questions and cant seem to locate your responce. Would you mind repeating it. "

Unfortunately the Mxz grips doesn't really get that warm. Pretty much the stator they put on the sled is maxed out. Any extra equipment you are running on the sleds electrical system will just make it worse ... like heated visor. Some people have posted that by putting expanding insulating foam inside the handle bar it helped get the grips hotter. A lot of people with the ZX complain about the luke warm handlegrips.

No! 0.45 mm = .018 Plug gaps are usually given in both inches/metric measurements (that are equal) since most plug companies do business around the world. Not a stupid question at all, at least you asked! Mike

Snowblood,
Engine backfires can be the result of numerous issues: a lean fuel mixture, a rich fuel mixture, if engine is not going past 3000 RPM it could be the DESS Syetem, ignition timing or failure, or the engine is overheating. The other items posted also play a part. Since the carbs were just serviced, its possible they were maladjusted. However you decide to get it fixed, do it before riding anymore. You can possibly damage the motor if you don't. Good Luck. Mike :cool:

In the original post, he said the mechanic set the gap in thousands not metric. Where he is from UP, I assumed they would set to mills.
