KTM 400 exc Review

2006 400exc

[@casmitherz]

You said it. The forks make our break a motorcycle. I'm putting 48mm KYB SSS forks on my 400exc right now. These 400s are the best.

[@heinrichvonkekelnazi393]

Mr Smitherz I love KTM's. I've owned 2 of them. A 250XC, and a 300XC-W. They're fantastic bikes, but you want to talk 400 thumpers, and Honda's XR400R will always reign supreme.

Nice upgrade!

[@C3HENRYS]

Yeah it is a nice upgrade. I got lucky with timing and price!

[@TheHenry4]

3rd gear power wheelies sweet!

[@BrianB1963]

I know this is an old video but if you're still around can you tell me what the weight on the ktm 400 is? I don't trust websites they never seem to be correct

[@C3HENRYS]

about 270

[@CKnudsen1984]

Hey, I did the same thing you did, just a little older on both bikes. I had a 2007 KLX250s with a two brother exhaust, dynojet kit, K&N intake, changed the gearing, it ran good, but just not the power offroad I wanted. So, yesterday I traded it for a 2004 KTM 400 exc. it seems to run good, starts right up, but seems like it idles a good bit higher than my KLX did. Did you notice this as well when you switched bikes? Maybe I just need to adjust the idle on my KTM. It has the trail tech vapor speedo, so no tach, so i'm not sure how precise I can get with adjusting down the idle speed. Any tips?

[@C3HENRYS]

Yes I would turn down your idle but only turn it down in small increments at a time. Enjoy that 400 it really is trail muncher!

[@CKnudsen1984]

ya, i might mess around with it. Did your bike come with turn signals and a speedo? Mine had them added on to make it street legal. I am somewhat confused though. I see there are a few different 400 exc models (a racing one, a exc-g USA model, etc..) so I am thinking mine is a 400 exc-racing model, but not sure. Do you know if there was only one type in the US?

[@C3HENRYS]

Mine came with the speedo and rear brake switch brake light but no blinkers. Mine was a exc-g which was for California green sticker approved.

[@paulyt9573]

Hi, I just bought this exact model and I'm a first time KTM owner, I can't tell from the video but does yours pop and crackle a lot when decelerating, mine does quite a bit especially when going down hills off the throttle also she idles a little slow and off beat and gets quite hot, mostly from the radiators, is any of this normal for these bikes. Has 288 hours on the clock, am I just being paranoid or are there things I need to adjust, service, clean and what not? P.s it is a beast on the trails!

[@C3HENRYS]

Mine did the popping and from what I was told it the pumper carb on that bike means it is running good. LOL

[@paulyt9573]

I think mines running lean as it's boggy on low rpm and idling slow and funny, just going to re balance the carb, but I guess I'll ignore the pops then haha, too used to 2 strokes.

[@C3HENRYS]

Does it have the stock pipe?

[@paulyt9573]

yes it does

[@C3HENRYS]

Mine to. I would adjust the Air/Fuel screw? What I had was the JDFM040 - JDJetting FCR-MX Fuel Mixture Screw to seasonally dialing in the air/fuel mixture. Good luck!

[@andrewturner9520]

The hot start lever is stock

[@C3HENRYS]

+Andrew Turner Good to know!

[@jeissonmendez418]

How often do you change the oil and oil filter?

[@C3HENRYS]

Every 3 rides filter Every other oil change

[@jeissonmendez418]

@@C3HENRYS Yeah but how long are your rides? Every how many hours it needs to change the oil?

[@C3HENRYS]

@@jeissonmendez418 Street is easier on these bikes so I go 4 -5 rides. Dirt only 3-4 race 1-2.

[@bulletben5837]

huh.. I was set on a klx450 too.dat ktm sounds plenty grunty eh

[@C3HENRYS]

+bullet ben It has plenty power but the 2006 400 Exc is a fast revving 250-350 feeling hit with more down low. Not as punchy as a 450 but fun for sure! The 400 has a very even power delivery across the rev range.

[@bulletben5837]

cheers pal
