Will my ktm 400 exc go across country

[Iwishiwasamechanic]

I have a 2006 ktm 400 exc, street legal. I plan on riding from ohio to the Grand Canyon . Is it gonna make it, will it break down a thousand times? Also I'm having a problem with backfire on deceleration, I have cleaned the carb replaced the silencer and done minor throttle adjustment. Other than that runs super strong will do 95 no problem cruises smooth at 70. Any help or input appreciated.

Post your question in thumpers.

Change the piston for a forged one if you intend to cruise at high revs. That is the most common failure I see.

I doubt it will actually cruise at 70, but regardless of speed it is still worth doing.

Consider fitting a Thumper Racing 453 or 473 kit, enhances the bike.

you don't tell us enough. Are you doing the TAT or slabbing it? If TAT, yup it will do fine. Slab? Fugetaboutit

Back fire on deceleration can be caused by air leaks in the exhaust, check all your joints for an airtight fit.

And if your bike is well maintained, I'm guessing it would be ok to cross the country on it if you can keep up with the maintance on the trip.

Kyler.. Uhh not exactly sure what that meant of hand . Tat(back roads) slabbing(highway) amiright?. If so ill be planning the trip on back roads. I'll have 50/50 tires maybe more street than that. An hour or two at a time riding . A lot of breaks.

Thetrev. I sealed the exhaust manifold and still have the backfire.

you need a bigger pilot jet.... and an adjustable fuel screw, and not an aluminum one that will break.... you probably have a 40 pilot, so try a 42...

popping on de-accel means the pilot/low speed circuit is too lean, and you need to richen it.... if it gets too rich, it won't start when it gets hot, so you gotta get to that happy place.....

Make sure the AIS is removed if the bike has one. Also, jetting that is off can cause it.....too lean at low throttle openings will cause a lot of heat that can ignite excess fumes from richer needle and main jet settings. Try turning the fuel screw out a quarter turn and see what happens. Speeding up you idle a little bit might help to. My KLR had some really bad popping whe I went to an uncorked leo exhaust...turns out I had actually gone too rich on the main jet and needle, but was a little lean on the fuel screw.....it was giving me one really loud pop on decelaration.

Grundy...thanks . I closed it then went out 2.5 made it a little better . I live in ohio the next warm day ill give it a full turn and see what happens.

TAT = TransAmerican Trail. Lots of threads about that here, great ride. Back roads, good time. Slow.

Slab = interstate/Highways. Fast, long, boring.

Grab two BIG handfuls of Adventure and GO! You will never regret it.

Thanks have never heard of the TAT definitely something I'm going to start researching . Not sure if you have done it but I plan on backpacking tent and a sleeping bag, ditches and woods, or even campgrounds how would that be on the trail?

Give a think or two about maintenance, and milage. You'll be doing some oil changes, and you don't want to run out of gas. Keep the chain well cared for, too, and watch your tires. Have a good means of carrying your gear, keep the bike tires down, and the rest is pure joy!

I think you should take a couple of trial weekends on the bike before you embark on such an awesome adventure. Traveling/ camping off of the bike is the only way to go in my book. But be prepared. Read a few ride reports, spend a little time to find the route that suites your style best, but most of all, don't forget to pull the trigger and go. I sure wish I had started 20 years earlier when the obligations were less pressing. Have a great time!!
