I pretty sure now im gonna run 27" bi/tri claws
I have a 2004 Foreman S will it struggle to push these things, and if not when adding performance upgrades should they all be done at once? I was hoping to get a k and n filter and a pipe, then later on jet it. But will it have any affect with just running the pipe and filter without the jet kit? I dont know how to jet, would the honda shop do it and not void my warranty? They are replacing my motor now, somehow the bottom end broke, the atv only has 800 miles on it running all stock equipment so why it blew i couldnt tell you. I have been gathering parts ready for its return in a couple of weeks, do they make power modules for formans? Need some help as i am new to the aftremarket on atv's.

I would say if you are getting the filter and pipe you should also get the jet kit! You could do the jet, it is a piece of cake, and if you need help the guys on here are great...they walked Railroader through it and now he can re jet in 20 minutes or less!!!

Yes your Foreman will turn the tires just fine.

Yes to when you are adding performance parts to do all at the same time. Reason being is you have to add more fuel when you add more air (snorkel + K&N air filter) Then if you were add a exhaust (more air being pushed out which results in using more fuel) need to fatten up the fuel again. So I would wait until you have everything you want to add onto it then get it jetted.

About putting the jet kit in, you can do it if you have any mechanical ability at all. And it can be done with tools from around the house.

Definatlely rejet. It will not run right if you don't. At first i thought i could
never do it, but the folks on here will teach you a lot of stuff. I have
become fairly good at doin' things to our Foremans with the exception of
takin' the disks out of Lady Foremans Supertrapp exhaust , but that
is a whole other story with in itself.

The only thing he's really not sure of just yet is how to get it in the mud.

I have that combo on my 450es and love them. I have a uni air filter, HMF eco pipe, and dyno jet jet in. The only thing I am missing is the clutch kit, which I highly recommend you also get. It will help sling them tires better. I ran my claws on my atv for about a month while it was still in stock form, and did ok in soupy watery mud, but bogged bad in the thick stuff, but really slung the goo when I added the mods. I think the clutch kit will be an x-mas present to myself and the 450 Get the tires youll love them. If you jet the carb yourself it will void the warranty, if the dealer does it it will not (like were idiots or something). I did my own and helped railroader with his over the net, so its not that bad. Well walk you thru it. As for the warranty dont even worry about it, they suck anyway I sold my ext. warr. back to honda. If you are worried about it have the dealer install all your mods then they cant complain it wasnt done right (again were idiots ) Any probs, concerns or ?? you have WE will walk youy thru them. I find it more satisfying to do ALL the work to my 450 myself, it gets you more aquainted with it, and if it does break you dont have to wait weeks or longer for the dealer to find the time to do the work, plus you save $70.00 per hour. Look at all the extra mods you can do with your savings!! The only thing I might not do myself is major eng. work or tranny internals (except the clutch kit). Sorry for the long post just wanted you informed, and let you know that... YOU CAN DO IT Larry

My 2 cents

If you are setting up for mudding, snorkle it (cheap insurance policy for water in crankcase/engine) and adjust needle valve.

Save the money you would spend on K&N and pipe and put on gear reduction.

instead of putting the jet kit maybe you should consider just getting a bigger jet from the dealer and saving some money...Iam not shure but with k&n filter, hmf pipe, and intake snorkel a size 142 jet should be what you need...ask around for advice many people on this site have these mods and would be glad to assist you.

NO it is not! Water can and will get into the crankcase even with a snorkle if you unexpectedly go to deep, or roll it while in the water. The below link has pics of how to almost guarantee water free oil. I have rolled my atv in a pond, filled the airbox to the top with water, and didnt get any water in my oil. Filled the carb with water but that is an easy trailside fix, unlike watery oil. Here is the link to the mods pics. pretty self explanatory.
MOD PICS
With the breathe rgoing up and over the carb the water cant flow straight down into you airbox like the factory allows it to. YOU can ask Railroader and Lady Foreman about this one. As her atv had a snork and still got water in the oil, I think that they have since done this mod, He said he was gonna but dont know for sure or not if he did. So water can still get in the oil with a snork, they can testify to that.

can you post a parts list of what is consists of and some details more on the crankcase breather its hard to tell by the pics, thanks

It is just about 2 - 3 feet of 3/4? 1/2? inch (cant remember size) hose from an auto parts store. and 2 hose clamps. The easiest thing to do would be take the breather off the atv and go to the local AP store and tell them you need x amount of hose this size. The carb vent is about 3 -4 feet of hose that I "tee-d" together and ran it along the frame and up to the handlebars using all the factory locations to hold it tight. Do the same for that at the AP store, tell them you need to put 2 lengths of this hose together and need an extra 3 - 4 feet of it. I think the carb vent and "t" is some old window washer tube from a car and the crankcase hose is old heater core hose from a car. Sorry I couldnt tell you more, as I had all the stuff lying around in the garage. For the CC breather, take the fitting on the airbox and turn it up, and attach the hose and run it over the top of the carb, and down into the motor. For even more insurance you can make a complete loop around the carb. Mine was until I worked on it. I forgot to put the loop back in it, and just ran it over the carb. That way the water has to make a complete loop around the carb which is highly unlikely that it will.

I didn't say it in detail but I asummed it was understood if you snorkel you also snorkel diff (front & rear), carb, fan and brake vents. Also the crankcase vent over the carb is assumed, however it did not prevent water from getting in my son's 450 when the dealership incorrectly installed the hose that runs from the carb to the airbox.

Not to sound like an *** but you can not assume that people will know what to vent, where and how when you tell them to put on a snorkle, cuz thats all theyll do, is just put on a snorkle. Also there are ALOT of people that snorkle thier atv and have NO clue to do the CC breather over the carb, or to extend the carb vent etc. They ASSUME that if you just put on a snorkle that you are saved from water entering the motor, which is not true. A snork only gives you SOME added insurance (just like liability), while doing these other mods ensures that you have "full coverage". Also you state that it did not prevent water from your sons 450, IF the boot between the carb & AB was installed correctly (from the stealer) it most likely would have. That is why I DO NOT trust "stealerships" for working on my atv! They are out to make $$$ any way they can, if that means screwing up your bike to get you in for more service then they probably will. Just think they were hoping to get you back in for a motor rebuild at YOUR expence. It would not be a warranty issue as the bike was modded, you can argue all you want that they did it, but you have to PROVE they did which will be impossible to do, as they are not the ones that did those mods. They will say that you didnt do such and such right therefore it is YOUR fault, not ours. If you insist on going to the stealer for service do YOURSELF the favor and CHECK all their work BEFORE you even leave the lot. I have heard of countless stories of the stealers not tightening this or that , not filling this fluid and that fluid, or just not putting bolts back in! Maybe some do it on purpose to get you back in for more service while others is a genuine mistake. Either way things happen and Id rather know before I even left the lot, that way I can raise a ruccuss if its not done right and Im not 50 miles out in the woods walking home because the ***hole that worked on my atv last didnt tighten something and now its broke. I can only blame myself if it wasnt done right seen Im the only one that works on my atv. Get a repair manual for your atv and do all the work yourself, then theres no one to blame but yourself and youll have the satisfaction of doing your own work without being "raped" by the stealership. Sorry for the rant everyone, just needed to get my point accross that dealers suck.
