@@jonthelamb4549 100% incorrect. Larger bore = larger vacuum therefore drawing in more fuel out of the same size jet. Sometimes you can leave it alone but most commonly an excess of fuel is drawn so a leaner main jet is required.
@@vipelink I see what your saying but larger vacuum adds more air also isn’t it? You would need bigger jets if you get a bigger carburetor because that would make a smaller vacuum then?
@@vipelink Please do not listen to this guy. The TRX450r is lean enough from the factory, DO NOT go to a smaller main with a bigger bore. It doesn't matter if you have the 04/05 Keihin carb or the 06+ Keihin FCR - you need to add fuel, NOT take it away. Dyno'd plenty of them to know better.

@@Ronaldo-mc4lt After looking at your owners manual it looks like Honda calls for Pro Honda GN4, HP4 oil in both the transmission and engine. 10w-30 weight oil.
In general is this a reliable atv? I am in the market now and was looking at 400s.400ex, LTZ and KFX. Just heard these were not relaible which is odd for Honda.
People say 450’s are not reliable because they ride the shit out of them and don’t maintain them I have a yfz 450 and I keep it up and change the oil regularly and no problems at all with it
@@mzondi1970 I have no idea the guy I bought my yfz from had just had the top end rebuilt and I have put at least 30 hours or more on it and I have never had any valve issues but I would have no idea how to fix them or adjust them if I did have an issue
My 06 trx 450 er has been extremely reliable still riding it in 2020 with no problems at all and i ride it about 4 times a month but im strict with oil change and maint.
This guy didn't even guage the shimes after the cam housing was on and he didnt pull off that huge allen plug on the back break side to see if the gear n there dot on the grar alined with the arrow on the block i found if u time this dot on the brak side of the engine vlock if i put that dot thats on the gear even with the arrow stamped on the block it will b really hard to kick start but if u out the dot on the gear alittle bit high at the top of the arrow stamped on the block it starts on the first kick wrong on the 04 and 05 models its stamped on the engine block 650ml of fluid but u only take the screw deiver screw out and fill the clutch side up with oil untill it staters coming out that screw driver hole then it full out your screw driver screw back n cant rebuild the 04 and 05 models anymore they have discontinued the cylinder head on the 04 and 05 and when there all gone u will not b able to rebuild the 04 or 05 models
so i followed this instructions and when i dropped my chain into the bottom end and then fished it out, the chain was somehow not long enough, anyone doing this on an aged bike (I have an 04) should be careful. I had my chain somehow fall around the metal guard that is bolted in the bottom end with an 8mm bolt. To fix it was easy though, but took me a while to figure it out cuz i had to drain the oil and coolant once again after refilling and pull the cover off with the stator, I then proceeded to attempt to figure out why the chain was not going up high enough and after several attempts to get it around that metal I ended up breaking a piece off the case trying to pull up on the chain, it was a little fin next to the oil return, so I thought I had to remove the flywheel. To get it off the metal I rotated my flywheel around which had certain holes in it and found the bolt holding the metal piece, unbolted it so the metal would rotate and the chain was free and was able to time it back up.
Hey bud what would cause the starter or something in that area to start smoking when I turn key over it sparks like its gonna catch fire when I push start button
Man, that is tough. Could be a couple things. Check the wiring and make sure your connections are good and nothing is shorted. You could also remove the starter and test it or make sure the engine turns over freely by hand.
@@rmatvmc ok thanks checked wiring gonna check starter next when I take timing chain off have to replace that its stiff as a board Iol I know its bad gonna go ahead do valves while I'm replacing chain think one of intake valves was off a lil but ill let you know when I check and let you know what the problem was..
I have a 2012 400x with a 440 big bore. Is it an identical process to this? Is there a way I can find a big bore rebuild kit? Or do I just buy a completely new big bore kit?
No the process is not identical. Yours is an air cooled bike for starters. The general idea is the same, but your engine is actually a little simpler. You will need everything new except a cylinder, that’s the most expensive pice anyway. You can get away with just a piston, rings, and new gaskets.
Yes, this is the kit I would recommend. It fits your specific machine 440 big bore kit. Do you happen to live in the North West? www.rockymountainatvmc.com/parts/wiseco-big-bore-replacement-piston-p?v=10197
Race quads like the TRX450R are being ridden hard and pushed to their max constantly . A generator is designed to run at way lower RPM's and not be under a lot of strain at any time, which lets them last much longer. Thanks for checking out the video!
Is there a full parts list to what you guys used so I can do this at home. Debating on big bore or standard bore for my trx I’m not really sure what to do. But she needs an overhaul bad.

Hi. It won't matter which side of the expander ring faces up (M, W). If it did, Honda would specify that in the manual. Just make sure that it's not overlapping itself, and that the gap of each ring doesn't line up with another gap. Honda specifies that the side-rail gaps should be spaced by 20mm or more. I have seen a side-rail that was damaged on installation that caused a new top end to smoke. Take your time and use caution during assembly and you should be fine. Let us know how it goes, and thanks for the comment! -Charles
Yay 450r content!!
Happy to see more atv videos, great info thanks
Keep sport quads alive!
More ATV how- to videos pls!

Wow you made all that look super easy!! And great Explanaing. How many hours I wonder was on that motor. If I missed it I apologize
Really enjoy and appreciate you guys content hardwork and dedication to the craft....👍🐜
Do you have a video 2014 TRX Honda ER how to clean the carburetor
“Next up, is my favourite part of the whole build - installing this heat guard.” 😂😂😂 Charles you kill me
How big will you increase the main jet with the big bore kit?
I just had too replace my valves on mine and know it doesnt have spark. Do you have any idea why it would do that?
Super great info. Thanks !!!!!!!

Is this the Cylinder works +4 100mm kit for the trx/ER?
What do those electrical switches do on the Carburetor? Its not like it controlled by a computer PCM like on Fuel injection.
What's it cost for you guys to do this labor wise I have an 05 and I have been considering have this done to mine and obviously you guys know what your doing
We don't do labor on personal vehicles. But you could call your local shop and ask them. They should have a pretty good idea of what labor would be.
Can you do a rebuild on ltz 400?
I have a 2006 Honda and I want to change the transmission oil. What type of oil can I put in it?
Pro Honda HP Transmission oil would be great: www.rockymountainatvmc.com/parts/pro-honda-hp-transmission-oil-p

Do you need to drain all the coolant every time you add new coolant ?
shouldn't need to as long as you add same coolant or compatible stuff

How much increase in power with the big bore kit?
1,000,000 horse power! JK! We didn't dyno it or anything like that but the owner said he did notice a good power increase from stock.

Poorly designed piston honda thought you guys were good engineers
says to torque to 16 ft lbs while he is using a rachet lmao
also cleans the cam cover and leaves a bunch of mud
