It can be checked with the engine in DLB. but you need the front cover and valve cover removed. See pages 7-25-26 in the service manual for a good description. Just remember the TDC mark in the inspection hole rotates twice for every cam rotation so make sure you are on the compression stroke. The valves will have some play to them on compression, will be tight on exhaust. When on compression with the TDC lined up in the inspection hole, the cam sprocket dot should be lined up at 12 o'clock with the index mark on the crankcase. If everything lines up your cam timing is set correctly. If you are good instead of checking the valves you can remove the plug and feel a puff of air come out on the compression stroke. But I'm not that good...lol Hope this helps..... I'm sure there are members here that can explain it better but this worked for me....

DLB your comment saying air is being pushed from the carb into the airbox to me leads to timing being off, valves are not working as they should. Could be a cam chain that has jumped a notch or two. That was my issue a few years ago on my 450, backpressure into the airbox. Good luck....

Welcome tommy, you found the right place with those Hondas you have, many like that around here.....

Here's wishing all members here a happy and safe Thanksgiving weekend. Side note, my pup chased a Tom out of our yard this morning, not sure if he was waiting for dinner or becoming dinner.....lol

Nice work Andy, sure looks alot different. I can say good luck finding a cheap 424, they are around but rarely see a bargain....

Hey Andy welcome to our forum! Nice looking ride you have, give us some info on it if you want. It may be kinda quiet around here this holiday weekend, but there will be a few around.

Cool little backhoe machine to make things easier, can you drive that up to Michigan so I can use it?

Great minds think alike my friend......

Hahaha, well I guess he has seen your post, sorry, I just saw your post AKATV....

Hey Chase welcome, we do have our forum expert @AKATV that works on these meters. I'm sure when he reads this threead he will make a comment.

Yep thanks to all the members here that have served in any way within our military. I enjoyed my time and made a civilian career out of mine.

Tsk tsk, you know what that means, 2 days in the chat barrel.....lol

Welcome Horsefly we kinda like our forum. There are alot of good Honda owners here with alot of experience fixing and modding. You should be able to find a service manual for your 400, click on the Service Manual link on the top menu. Looks like there is one for 1995-2003 Trx400. We also have a Chat link on the top menu, there is usually some discussion going on in the evening, join us sometime.

New fenders sure give it that brand new look, no scratches or scrapes...

Wow she's a shiny old girl, looks great...

Here's hoping for success......

Looks like the parking lot is full...

Hi Ugmug, yes I saw you twice in the chat last night. Do you use a cell or PC, because the screen on a cell is pretty cramped? As fishfiles said, just type something in the white box and hit Enter on a PC. I just tried on my cell and don't see a way of posting, I can type a message but as of now can't post it. I will have to check into it...

I guess its good you got alot of hunting before all this has happened.....

Gee sounds like you have some good doctors working her issue. I sure will keep you guys in our prayers wheeler, keep us posted on progress if you will please.

Well she runs, good deal....

In these pics looks like some kind of carnival ride....lol Part time help huh, with your hours good luck finding anybody. Most people want some kind of life.....

Welcome to the site danlee, we do have a ton of Foreman ES showing up here so you have alot of ideas being bounced around. I will post a link to a thread describing how to properly prep ES Hondas by our best ES guy here. You are welcome for the plug retro....lol

Hey AKATV you are certainly drawing quite a crowd, how do you keep up on parts to fix all these?

Welcome s.e.r, saw you in the chat section last night, stop by and say hi sometime....
