Picked up my Legend today from the Triumph dealer after having picked it up last weekend in MI. The bike has 3k miles on it. I told them to go over the bike and change all the fluids which they did. (I also had Avon Storms installed too-- I think that was a good choice. See previous post with excellent recommendations for replacement tires.)

Here is the problem. The mechanic said he swapped out the stale fuel which, according to the former owner contained stabil. He said he adjusted the carbs as they appeared gunked up. When I picked it up, the bike fired right up and sounded great. Once home, I had some difficulty starting it and once it was running, it began missing--even once warm. When given throttle, it backfires from the left pipe. I took it for a quick spin around the neighborhood and the thing was kicking like a buckin' bronc. While idling, I can physically see the carbs kicking back. Yes, the simple solution would be to bring it back to the mechanic--but they are 2 1/2 hours away. Am I running rich on the left outside carbs? Any other suggestions? I THINK I love this bike, but she ain't puttin out on the honeymoon! As always, appreciate the feedback.

The bike is simple a POS. You should just sell it for a really good price to your brother-in-law. Pics please.

If its the Legend that was on cycletrader.com from MI, you got a great deal. Be patient because most likely this isn't a big deal.

One of the more mechanically proficient guys will give you a good answer, but I'd suggest adding a fuel system cleaner like seafoam, run it through and see if that straightens it out.

Is it possible you're running it with the choke on?

Adjusting the carbs doesn't fix 'gunked up'!

You didn't mention where in the rpm band the bucking occurs or at what throttle settings -- small throttle, full throttle or transitioning from one to the other -- so it's a bit difficult to be specific.

Most likely you've got dirty pilot jets and a load of nasty stuff in the fuel system.

A problem on the left side is a pretty good indicator that fuel has been evaporating in the carbs and the buildup of crud is greater in the lowest carb with the bike on the kickstand.

Figure out where the problem is (rpm & throttle position) and get back to us. If it's dirty pilot jets the problem will be at small throttle settings.

I'm with Jimmy on this...sounds all to familar....

1) Remove your petcock and clean out the filters...takes 5 minutes.
2) There is an in line filter at the point where the fuel line intersect with the carbs....I replace mine annually...most people have no clue this exsists. They are a couple of bucks.
3) Run SeaFoam/Hot Shot, etc......if that dosen't clean out the grime, pull the carbs and give em a cleaning.
4) Just a thought......you stated the dealer put in new fluids....I wonder if he put new gas in over what was sitting in the tank or he totally drained it and then replaced with new gas....just to be safe, I'd dump the tank and start new.....hell, ya gotta pull the tank to do the petcock...it's only a couple of bucks....put the old gas in the lawn mower. (or around here, in the snow blower)

My 95 sat for years before I bought it.....I ended up pulling the carbs after playing around with quick fixes....well worth the time.

The problem occurs primarliy while in first gear. I have to coddle the throttle when getting on it otherwise she stalls. Once I get through first, the bike appears to be strong. While in first, after 3,200 rpm, she seems to be comfortable. I'll try the seafoam and see if that helps at all. Appreciate the feedback.

If it's happening at full throttle then the problem suggests bad ignition coils.

If it's happening at part throttle then it's most likely dirty pilot jets.

Thanks to those who recommended Seafoam. Miraculously, I added the appropriate amount (of course being a man, a bit more than recommended!), ran the 99 Legend about 20 miles and it all evened out. This Seafoam is the SH$&! I'm a fan. Disclaimer: I am not a Seafoam retailer nor do I have an interest in Seafoam products.

So the problem was at part throttle and due to dirty pilot jets.
