400EX Carb Swap on a Honda ATC 350X -

[@patinabunker5340]

Good video Preston. No more leaks. No more flooding.

[@ThisOldTrike]

Thanks brother! Yes sir!

I love the factory header because you can run the nice OEM guard. But, if you want the performance out of that Supertrapp you need to find an old Cobra or DG head pipe. They are quite a bit larger than stock; I found 2 within days for 80$ each just a year or 2 ago, they are out there. The decompression cable should have 1/14th of an inch of free play at the cylinder head lever at TDC on the compression stroke, but you have to set the valves first, then set the cable. You got it to work but if you want to fine tune it, loosen the cable, set the valves, adjust the cable with the proper free play. Great video, helps out the trike community...

[@ThisOldTrike]

Yes sir, I had this thing dialed in perfectly after me and my buddy rebuilt it. One kick every time in flip flops... now it's just out of tune. And regarding the header, I know a guy in PA who modifies 400EX headpipes to make them work the 350X and you still get the nice look of having the heat shield (400EX style though). I keep asking him for one but I'm always catching him at the wrong time.

They work great on your big bore 250ES-SX as well kiddos. 152-154 main jet, stock pilot, needle down 1 clip would get you in the ballpark

[@ThisOldTrike]

I've got one of Greg's kits just waiting for me to get my act together! One of these days... Maybe I'll put it on the 88??

[@tricycleguy2657]

10:25 , one time out of curiosity I pushed the decomp in the direction of pull and felt it riding with the valves right before lack of compression shut it off. It enlightened me to where I now knew how much lash was there. I always heard that if adjusted wrong they wouldn't start or kick hard etc... kinda like the clutch you can feel the free play, but unlike a clutch cams are eccentric so it must be done while running to see if the distance from the resting (slack) position to just cracking the valves off the seats is far enough to reduce compression but still start easy and not too tight as to have compression slip by when its running

[@treasurelife2270]

My 350x is completely stock😂😂😂! I may get a 400ex carb with the boot from 223 cycles

[@ThisOldTrike]

You won't be disappointed!

[@hughiemaceachern5282]

After I rebuilt my 350x even with decompression kicked hard so I use to dtc then kick start first kick every time mine was a good dependable bike I road that thing every day all over hell I loved it till I broke my back on it sold it same day wish I never

[@ThisOldTrike]

Man, I'm so sorry to hear about your injury... that sucks! When these 350X's are dialed in, they are fantastic machines!!

[@southeastvintagecyclerescue]

That middle shop area is really coming together. Looks good. Glad that overflow hose issue didn't catch you on fire during the ride!

[@henrypauley4877]

Awesome video again keep it up 3 wheelers forever

[@ThisOldTrike]

Thank you sir!!

[@tricycleguy2657]

34mm boot +35ish years + 38mm carb =wrestling match only ever used oem boot... never used a 300ex boot

[@stevenbrooks1243]

Right on just picked up a pretty clean original 400ex now I have that and the TRX700XX The new King of the hill lol😊

Have you ever tried running any K&N air filters on any of your Hondas?? That's the preferred set up for Glamis. K&N air filter with an Outterwear dust cover over it and remove the airbox lid. Seems to work well. That's how I had mine set up for riding in Glamis. Glamis is located at the south eastern most corner of California, next to Arizona and Mexico. It's a big place. From the main entrance to the Border of Mexico is 20 miles. GPS with the Glamis map downloaded is definitely a must!! A pass to go into the park can be purchased in the nearest city Brawley, CA. It seems like the most unusual place for Dunes, because the road leading out there has farms on either side, and slowly but surely it turns into Dunes!! Season starts in October and runs until May. Otherwise it's way too hot in the desert during Summer. Shoot we were there during Thanksgiving and right before Christmas, some days the wind would kick up and it was a stay in the motorhomes day. We had to go into Brawley one of those December days, to buy shorts, because it was 80° that day, but once the sun started going down, it cooled down. As it got dark nearer to sunset, it was time for jeans and a sweatshirt or hoodie. LED light bars and LED buggy whips are a must have for night time riding. Headset radios help you stay in contact with your group. All gas cans must be red, and DOT approved, otherwise BLM will hit you with fines.

[@dc6233]

Your Supertrapp needs my polyurethane indestructible grommet!! That's why Supertrapps crack at the mount, the rubber they used was terrible and people often solid mount them, the frame flex's and they crack the aluminum mount off.

[@ThisOldTrike]

Where can I get one??? Would love to put one on and shout you out on the channel man!

[@tricycleguy2657]

2:20, shelf looks great 👍

[@ThisOldTrike]

Thanks brother!

[@mike9500]

Curtie is awesome!

[@ThisOldTrike]

Yes sir!

[@robstrex]

Thanks for the video I messed with decompression on mine and never even moved on either side and def hard to start Should I just try tightening it up some?

[@handsolo6241]

Seems like I suggested that 6 months ago.. j.k. love the channel

[@ThisOldTrike]

Thanks for watching man.

[@Op1zilla]

My friend did this to his dads 350x whenhe rebuilt the top end = high comp oversized piston,, was hard a hell to start until he swapped out bigger carb, then he let me ride his 700xx around block with him an he thought he was gona pull on me 👽👍✨

[@mike9500]

it's also better to remove the decom cables as they cause more issues than good.

[@ThisOldTrike]

I don't think I agree with that statement...

[@GarageWorx]

Wonder what material that 3d printed part is made out of. ABS?

[@223cycles2]

TPU

[@JohnVHLife]

I made a video on how to do this also a couple years ago, didnt need anything but the carb. What did you settle on for jetting?

[@_357_]

How do you clean your fork boots?

[@mike9500]

how ya need one of the mike's atvfix CDIs

[@shawnrice7179]

give it a shot of either

[@ThisOldTrike]

That wasn't the problem though.

[@doc_teamwaxoffroad]

👍👍👍

[@ThisOldTrike]

Thanks brother!

[@jasonlawrence224]

What are the benefits of the the 400ex carb?

[@ThisOldTrike]

It's a larger carb, so if you have engine mods, it will feed your engine more efficiently. Also, it had an accelerator pump, so it make it easier to start by allowing you to squirt a little gas into your cylinder before you start to kick.

[@Gunnyminoso96]

Did you have to do any tuning?

[@ThisOldTrike]

This machine already had a 400EX carburetor on it before hand, so I already knew what jets were working for me. Curtie suggested bumping up my main jet from a 152 to a 155, so that's what I did and everything seemed to run great.
