400ex HMF slip on test (all 3 inserts) 

168 main jet.

I got one similar 8 years ago... It just by chance came with the same HMF stage 3 and jetted w k&n, Mint 05 Honda 400ex. Original tires barely half worn probably less than 50 hours. When I test drove it I almost crashed in the storage unit lot!!😆🤣 I got going so fast and could barely stop in time..Barely Stopped like 3ft in front of a unit!!! I'm like damn!!!😁 Sold!!!! Brakes were 80% too... lol $2200. Still rips hard and looks like new considering it's age. I've bought several extra Replacement parts. Tires brakes Tires brakes Battery Air filter Chain guides and rollers In addition to several other small items.. But still stockish Basically lol😆🤣

You should check out the vids of my 87’ 250x with the HMF slip on, I also got a Suzuki LTZ-400 with a yoshimura slip on.

Nice vid

Badass let's Rip she sounds like my Honda

I have the sparks full exhaust and I almost like the way this sounds better...

What main and pilot jet did u use

On stage 3 do you have the spark arrestor in

Did the slip on require a exhaust gasket? Where you tightened the clamp, did it just slip on the exhaust and a tighten the clamp and ready to go?

I took the muffler off of my old Trx300ex and drove it around like it and loved the sound of it but it hurt my ears

What jet kit did you use and what size?

On the stage 2 did you jet it.. and also if I ran the stage 1 do I need to jet it..

Do you live in California? And what insert did you end up running with?

The dog is like not again..

Where’d you get this at?

LoL I said do it without the muffler on in u started

How much was that exhaust??
