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.

@restoroosterohv 4 ай бұрын

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.

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

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.

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

@restoroosterohv 3 ай бұрын

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.

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. www.ebay.com/itm/314602234399?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=zPFaiN4iSpi&sssrc=4429486&ssuid=K8gv8TS9R3W&var=&widget_ver=artemis&media=COPY

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!

@restoroosterohv 4 ай бұрын

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

@paulbulski6609 4 ай бұрын

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

As you slide the throttle shaft through the bearing, the steel washer goes first, then the nylon washer, then the slide link.

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.

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....

@restoroosterohv Жыл бұрын

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!

@DanColeman-lp1bz 5 ай бұрын

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 !!!

@restoroosterohv 5 ай бұрын

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%

There is nothing like a fuel injected bike. no carb to rebuild, just a fuel pump and an injector

@restoroosterohv 4 ай бұрын

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.

@bounceorbreak 2 күн бұрын

1-How much are your pump and injectors if/when they fail? Because I can get a rebuild kit as low as 20 bucks, and fix it myself. 2- if you wanted to change your bikes character how much would an ECU swap or tune cost? A carb can be jetted for around 100 bucks. And an adjustable fule screw and know how will keep you going in different temps and altitude. 3- I'll give you this it would be nice to be able to take your spark arrestor out, change exhaust system, and use aftermarket air filters without having to diddle the fuel screw.

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.
