I was looking for something that explained why my DRZ400 is having issues. I think you answered all my questions. Great video. Thank you.
So glad I was able to help. Thank you for your feedback and support.
I don't have a FCR carburetor, but the video was extremely informative!

Great job 👏 thx. Very helpful.
Thank you for your feedback and support
Just what I needed to see. My 08 crf450 sat for 5 months and didn't want to start. Noticed the carb wasn't pumping . Found the bowl full of jello , midbody gaskets were junk, and pump diaphragm was shot. Thank you for the great content, I'm subed . Now i have to figure out why my rmz450 is smoking like a train after i just replaced the piston , one valve guide , valves and cam.
Use non ethanol fuel if you can at 90 octane minimum in your Honda. The RMZ, check to be sure the rings are clocked properly. Also, check your valve play in the guides and look for cracks in the guides. Thanks for your support.
@restoroosterohv Thanks for the help , it's much appreciated .
You're welcome@@AlvjaDahat
You the man!
Haha, thanks.
It's interesting to see how alike these Honda variants are to the Yamaha flavors. Nice video. Much appreciated!
Honestly, I use the same kit for all of the FCR variants. Of course, not everything from the kit fits every carb but the mid body gaskets are all the same. Thanks for your comment and support.
Yeah, I'm currently dicking around with the FCR on my YFZ450. It's running great, but bogs from idle to full throttle. Pretty sure adjusting the ap timing will sort this out, but if not, it runs great under normal operating conditions, so I'll just leave is as it is. Still kind of annoying as I personally like everything functioning 100%.@@restoroosterohv
@charlesevenstad I think you are on the right track with your diagnosis. Check that the AP is even functioning
If you're reading this, this carb is the same as a 2007 Honda Trx450er
All of the FCR carbs for the race bikes are similar. In fact, I buy my rebuild kits for the YZ250F because they are the cheapest and they work on almost all of the carbs I have rebuilt.
@@restoroosterohv so i can use yz250 carb rebuild kits for my trx450?
@felixmartin92mf most of the seals and gaskets should fit perfectly. Not saying that all of the parts are interchangeable but the mid body gaskets will. Keep in mind, you are looking for YZ250F kits, not YZ250 (2 stroke). Totally different setup.
@restoroosterohv9030 the jets might be different then, but the gaskets are practically the same. Oh yeah 2stroke is another machine lol
I never got to see you replace the o-rings on that swivel piece that the fuel line connects to. That's exactly where my carb is leaking gas from...
07 trx450er
On carbs where the feed tube comes out, it’s (usually) as simple as removing the retaining screw and pulling it out. Replace the o-rings and reinstall. I like to use a little dielectric grease on them before sliding it back in.
@restoroosterohv You're the man! Thanks for the tip. I just had my carb done with a rebuild kit. Didn't realize the mid had separate gasket kit. Thank you for making this video! Gives me enough info to confidently do it myself.
You’re welcome. I typically buy the mid body gasket kit for a mid 2000s YZ 250 F. There are obviously some things that won’t fit your model, but the mid body gasket should and the kit is super cheap, like $12 off of eBay.

Quick quiestion, by the way thank you for the video, is there any adjustments for the sliding plate on the screws on top,please let me know,thanks
Can you elaborate or send a picture to restoroosterohv@gmail.com
There is nothing like a fuel injected bike. no carb to rebuild, just a fuel pump and an injector
Agreed. Not to mention that they automatically adjust for temp and atmospheric pressure. However, if a carb is maintained, it will just work where FI has a bunch of components (pump, regulator, throttle body, injector, air temp sensor, MAP sensor, water temp sensor, capacitor, power coils in the stator, tip sensor and TPS) that could at any time fail and leave you stranded. I’d still go FI. Thanks for your comment.
I’m wondering how many turns to set the idle screw back to factory such as the , oil mixture screw which was explained.
There really is no factory setting for the idle screw as far as turns. Once you start the bike, adjust the idle rpm to the manufacturer recommendation.
First of all, thanks for an amazingly detailed video. This is exactly what I needed. Once I disassembled and cleaned my carb I found two of the bearings on the "carrier?" (with the four wheels) are shot. Is there a way to replace just those bearings? Can you replace that entire carrier? Appreciate your thoughts. Thanks!
I appreciate your support. If you get some measurements off of the bearings, you can probably order some on Amazon or eBay. Of course, all of the parts are
Usually available OEM through your local dealer or somewhere like Rocky Mountain ATV
As a follow up: Before I paid $99 for a used throttle valve off eBay, I blasted the bearings with carb cleaner inside and out and much to my surprise, it worked! They didn't look dirty at all, but they now spin like new. Just a heads up if you run into some "bad" bearings
Great tip. Thank you. I sure do love brake cleaner.
I found a replacement float valve seat on eBay from mxdude out of the Netherlands .
Not sure I would know how to replace it. Mind sending me the link to restoroosterohv@gmail.com?
I've only got 4 to clean on my bike 😃
And sync probably
what grease did you use on the shaft bearings upon reinstall? thanks trying to rebuild mine and this is first time to ever do anything like this. i have suzuki super grease C so far at this point. thanks! and what grease for the glistening o-rings?
I use dielectric grease on the o-rings. You can use that on the shaft as well I used standard bearing grease on the shaft in this build.
@@restoroosterohv thanks!!!
The kits didn't come with the accelerator kit. Did it come with the mid body o rings?
No and no. These are separate kits.
Hello
I bought a used yz250f 2009. I had some issues with how starting.. I dit valves clearances, carb clean.. and that help a lot..
But I notice that my carb hot starter was missing.. and I thing thats the problem..
My question is.. Do a hot starter really make huge diference to start the engine when is hot?
Thx 🙏🏻
Yes, it leans the mixture. If it is not in the carbs at all, that is going to be a problem
@@restoroosterohv thx man 🙏🏻
You’re welcome
May I ask where do you buy carburetor repair kits?
Sure, Rockymountainatv.com
i dont think the ethanol fuel is quite as bad as folks make it out to be, i ride about 250-300 hrs per year in socal, dont really care what fuel i put in the bike at the gas station...what i do and i think anyone with a carburetor should do is to drain the fuel from the bowl after every ride...just leave fuel in the bowl when your riding....most bowls have the drain screw, i had to buy a later model bowl for my crf450 to get that screw...this way you can rest assured the carb is pristine inside since it really is the heart and lungs of the bike....
You hit the nail on the head. Drain the carburetor to get the alcohol out of it. If you do that or turn off the petcock and run the bowl dry you will be in far better shape. Most people wont take the time unfortunately. Ethanol remover additives don't work either. Where the problems come in is the fuel in the tank will attract moisture from the atmosphere over time. If you run the bike and replenish the fuel on a very regular basis, it shouldn't be as much of an issue. Also, on older bikes, the rubber fuel lines and internals of the carb are not ethanol compatible and will be damaged over time. Some people don't have access to ethanol free fuel and have to do what they have to do, I get it but I would avoid using it in any small engine if at all possible. I've even seen corrosion in the fuel pumps of the FI bikes due to it. Bad Stuff. I could go on about the decrease in power that ethanol produces over pure gas but we'll leave that for another day. Haha. Thanks for your comment and for watching!
I have 1st hand experience with ethanol fuel ! Bottom line is don’t leave it sit in your carburetor for any extended length of time it it will damage it !!!
It’s not the ethanol that damages the carb, it it the moisture that it attracts. This moisture will corrode the aluminum. Ethanol in itself does no damage to aluminum parts at least at 10%
@@restoroosterohv you are absolutely right the ethanol attracts the water which in turn corrodes the aluminum
I currently have mine apart and didnt see where the plastic washer went. I saw you put the metal washer on after the shaft went through the spring and bearing. Was the plastic washer already on by that point?
As you slide the throttle shaft through the bearing, the steel washer goes first, then the nylon washer, then the slide link.
Thank you, you are a gentleman. The video is fantastic.
@jaymarshall2326 your welcome thanks for watching.
Where do you set the idle screw for slide height
As a base setting, just a bit above fully closed will usually work
what kit did you use? if it was an ebay kit is it still running?
I can’t answer about it still running as I sold the bike. I use the same kit for all of these FCR carbs. It is an eBay kit for the YZ250F and they run me about $12 each. Not everything in the kit works for all carbs but it is the mid-body gaskets that I am after when getting them. They fit well and can’t beat the price.
Another victim of ethanol fuel. I used VP 94 octane , non ethanol in my road bikes for years until it got to expensive in the 5 gallon pails. Those engines could sit for 1.5 years and start up like and run like it was 2 weeks ago since started. F Al Gore and his ethanol mandate.
Those were the good ole days. If you go to pure-gas.org it lists all of the ethanol free stations around you. At least you can still get it in most places.
I believe you meant to put episode 57 instead of episode 56 since the last video was 56
Good eye, I’ll get that changed. Thanks
Hey do you have a link to the set you used? And do they ship to the Netherlands?
If you are talking about the rebuild kit, I got it from eBay. It will depend on the seller as to where they ship.
@@restoroosterohvThanks for the rapid response! I have a WR450F but every kit says it doesn’t fit my bike, pretty sure the kits will fit my bike as i have a keihin. Any thoughts on this?
@ukie188 I use a yz250f kit for almost all of my FCR rebuilds. Some parts of the kit don’t work on all the carbs but the main seals are usually all the same.
@@restoroosterohv aah alright thankyou! Will try it out soon! One more thing my, the plastic T part on the left side of my carb where the 2 hoses from the vacuum line connect broke of on 1 side. I will be able to put 1 vacuum hose on but the other is now just a hole, is it replaceable or can my bike run fine with just 1 hose connected to it?
Those hoses are just vents and the bike will run fine. The problem you’ll probably find is that when the bike gets laid down fuel pour out of that.
If people would use there bikes and drain the damn fuel if being stored longer than two weeks this wouldn’t happen. Stop being lazy
I use non-ethanol fuel as it is very obtainable here. If you have to use pump gas, at least cut the petcock and run the brown dry.
