Keep it...ride it and make videos about the the bike , about the repair and maintenance . A lot of guys run the older bike and its cool to have new videos on them . That bike looks like a gem .
Would have been fun to strip the pump, probably just a seal or stuck valve. Also could have just pressurised the tank a bit from the cap breather. That's a clean bike though! 👍
Best all around bike ever. I have had a WR 426 and 450. Trail riding, MX or street bike they are fantastic bikes. The ones we get in Spain are street legal.
I now live in Spain too and want to buy a WR 450 as well. Is it allowed to ride it with the full horsepower on the street? In Germany we have to tune them down most of the time :/
@@michaelnutzel2226 The old 426 had a throttle stop and a gray wire that could be cut to give full throttle and full power. The new 450’s are full power from the dealer.
it would be good to see a fuel pump disassembly vid to see why it failed and can it be cleaned or repaired. im glad i have an old bike with a carb, the fuel injected components are so expensive. thanks for the vid.
I got a non-running 2009 WR450f on the cheap. Previous owner broke the carb when trying to remove it from the bike to clean it. I'm looking forward to a Lectron carb and some other goodies 🙃
had one. I became president of the tippy toe club. my mechanic warned me, but he still cut the grey wire for me. it went really fast. put a snow sled on it. couldn't get back on it in the snow once it fell over, b/c it now sat 10" higher than before. sold it for what I paid. bought an older 2009 KTM250 XCF thumper. fortunate to have survived to tell this story.
Thanks for demonstrating what the proper pressure should look like. I was hoping you would. I have a 2012 and your video will be helpful for reference if my fuel system fails. Thank you!
This is why I’m so partial to carburetors, so much simpler to troubleshoot on the go. And before you say anything about jetting being a pain in the ass, understand that I’m talking about MODERN carburetors (Lectron, SmartCarb, etc). Totally worth the price for ultimate reliability.
I don't think testing the fuel pump so close to the battery was a good idea 😬(6:05). Also, quantum fuel systems makes some good aftermarket fuel pumps and allballs have some fuel pump rebuild kits fyi.
I thought so too. I think any car fuel pump repair or service expert may able to fix it, because those things are way more costly & people would rather have them fixed than changing them outright.
@@Andy-co6pn it is. I just bought a non running wr450 as well. I rebuilt the fuel pump assembly with new parts and put a new injector in it. It runs like Godzilla now
Seems like a lot of monkey motion to avoid buying a $10 fuel pressure gauge. Also, the likely problem is something stuck in the pressure relief on the pump. You might want to have a look for anything obvious before plopping down $360 for a new one...
I just bought an 11 with the same issue. Bought a Amazon pump and quantum pressure regulator, rebuilt the pump and it didn't work. New Yamaha OEM pump and it's running again. It's more expensive but well worth it.
Hello again friend, you know that my motorcycle is jerking, would you know where to start checking? Already checked the spark plug and fuel pump and they are OK, it is a wr 450 injection, by the way, excellent explanation since I don't know anything about this type of injection motorcycles and your video is great to start learning the system.
Just bought the same bike under the same circumstances, VERY cheap, turned out to have the opposite fault on the same part, the fuel pressure regulator was blocked up somehow, causing the injector to over-fuel as a result of too much pressure. Would start and run for 10 seconds before bogging and stalling.
Good information , very nice and thank you. You make really good project bikes so keep it and built it up with top quality after marker parts as you usually do.
Get it running and working really well and flip that sucker! Make a really good bike for someone that can't afford the ridiculous prices of new bikes. But to keep it and put more into it, idk, then when you go to sell you have to outprice some people to get some of your money back. And the newer generations seemed to make big improvements. At least according to youtube, haven't rode them.
Yeah, because everybody has an extra tank and pump and an air compressor laying around for just such an occasion...or you could just buy a cheap fuel pressure gauge. LOL...
I had a starting issue with my 2012 WR450 similar to this one. For anyone watching this and want to save $400 by not buying a oem Yamaha fuel pump. He shows at 4:44 that the fuel pressure regulator is spewing gas. This regulator should do this when the pump is over pressurizing the system. Therefore it should not have any fuel coming out on primming. You can buy aftermarket fuel pressure regulators for around $40. That is what I did and my issue is fixed. This will not fix a bad pump but will save you from dumping a ton of money in a fuel pump you may not need. I AM NOT A MECHANIC.
@Cannavis Is the aftermarket regulator integrated into the pump body? Which can be unbolted from the pump body and replaced? Or did you have to install a generic inline regulator (similar to a fuel filter on a carb bike) and stuff it somewhere under the frame and plastics? Also, I assume it's a Chinese knockoff regulator...how long will that really last?
@@drott150 at 4:44 you can see the black circular part dumping fuel back into the tank. the white portion you see in the middle of the black regulator has a lip on it, The black portion is a clip. If you slide the black portion off the white tab on both sides the regulator slides off.
@@drott150 also the regulator i bought is American made and has been working fine with 0 issues sine i replaced it. it is attached to the pump body which can be seen at 4:44 I bough a USA Quantum Fuel System OEM fuel pressure regulator from amazon
@@Cannavis Excellent info, I really appreciate it. I just bought one of these bikes yesterday (a 2014). It runs great, but I do want to understand its F/I system and how to maintain it without breaking the bank or doing dumb repairs where you just replace everything instead of what's actually needed. Looks like you cracked the code bruh! Thanks again.
i have a 2012 WR450, purchased brand new in 2017 luckily. Fuel injected and mine will start and run for about 20 seconds and die. thought it was bad gas, changed it all and still same result. any possible things to check for? bike has roughly 70hrs give or take.
Good troubleshoot video. Why do they have to put so much complicated shit on bikes these days? If it aint broke don't fix it. I'll stay with older simpler bikes thanks. They are just as much fun. However it was an interesting video. I did learn several things .Thank you.
There is always one of you in every crowd, the battery leads are isolated from any exposure to fuel it's a basic design feature of any pressurized fuel system.
@@robh3267 And there's always one of you in every crowd. Anytime open liquid gasoline is being spilled and literally sprayed like that and electrical switches and motors are being switched on and off? The bike should be outside well away from the house. And at a very minimum a garden hose with a sprayer nozzle should be right there by your side with the water pressure on. And preferably with a CO2 extinguisher present to help put it out quickly without using water which is less effective at dousing gas fires (especially after the plastic tank melts and dumps however much you have in it, which should be the bare minimum amount needed). And if you think internet safety nazis are annoying, I agree stupid ones are. But in this specific scenario, I'm telling you he's putting himself and his place in grave danger. Don't ask how I and many other old guys learned this the hard way.
Awesome video man, that air pressure trick to start the bike and verify a fuel pressure issue is very clever!
Glad you liked it! thanks man!

Great suggestion, thanks Steve
Keep it for sure. I'm sure you would do something super cool with it
thanks Sam!
I'd be interested to know whether the fuel pump itself was faulty, or whether it was the pressure regulating valve?
I got a non-running 2009 WR450f on the cheap. Previous owner broke the carb when trying to remove it from the bike to clean it. I'm looking forward to a Lectron carb and some other goodies 🙃
let me know how it runs with Lectron, thanks!
Tip: use the spark plug cap to remove the spark plug =)
smart! thanks ;)
?
I like the idea of fixing the fuel pump. And wouldn’t it be nice to fix the electric start as well? 🤤
you bet I am fixing it all ;)
had one.
I became president of the tippy toe club.
my mechanic warned me, but he still cut the grey wire for me.
it went really fast.
put a snow sled on it.
couldn't get back on it in the snow once it fell over, b/c it now sat 10" higher than before.
sold it for what I paid.
bought an older 2009 KTM250 XCF thumper.
fortunate to have survived to tell this story.
Your in tank fuel filter might be cracked. This will not allow full pressure. It happens on KTM’s sometimes.
man, i loved this one. super informative and good thought process
Thanks brother, glad you see it that way
I learnt something thanks to you. Waiting for the next!
right on Charles, glad it helps
Thank you for not clickbaiting us by telling us
you paid $18.00 for the bike like so many other
channels do!

Cool vid, don't forget the vid on reparing it. KEEP it, they have heaps of grunt and are alot of fun to ride
Thanks for the video. I have the same bike as well and suddenly its stop starting. Might check the fuel pump and the spark plug
I don't think testing the fuel pump so close to the battery was a good idea 😬(6:05). Also, quantum fuel systems makes some good aftermarket fuel pumps and allballs have some fuel pump rebuild kits fyi.
not sure I want to go with made in china for the fuel pump..
@@dirtniron his issue is not the pump it is a fuel pressure reg that u see at 4:44 and Quantum is a USA company btw.
Is it possible to fix the fuel pump, instead of replacing the entire pump?
I'd definitely be looking into that. My guess is the non return valve has stuck
I thought so too. I think any car fuel pump repair or service expert may able to fix it, because those things are way more costly & people would rather have them fixed than changing them outright.
@@Andy-co6pn it is. I just bought a non running wr450 as well. I rebuilt the fuel pump assembly with new parts and put a new injector in it. It runs like Godzilla now
I’d be fixing the pump
I'm on the same page, there has to be a way to service that pump or at least apply back pressure and see if any solids shoot out.
looks like the pressure bypass valve failed, one of my ktms did it and it was fixable without buying new pump.
I wanted to replace it but there are only chinese replacements.. I want to have reliable bike after I am done. What did you use at yours?
@@dirtniron bet u find most the originals are Chinese, I just pulled the relive valve out and change the spring to a slightly heavier one.
Love those model years of the wr450
Keep it, and make some maintenance videos about it, i have the exact bike and love it, but videos about this model is very limited
Good vid. I'd like to see morr on the fuel pump, maybe strip it down and try to fix it?
Seems like a lot of monkey motion to avoid buying a $10 fuel pressure gauge. Also, the likely problem is something stuck in the pressure relief on the pump. You might want to have a look for anything obvious before plopping down $360 for a new one...
Exactly.
Thats very clever If i had a project on the go i would flip it if not i would build it but i cant tell you what to do
I really like how it looks
Get a Magnetic spark plug socket saves you need to fish the spark plug out with your long pliers ✌️
I just bought an 11 with the same issue. Bought a Amazon pump and quantum pressure regulator, rebuilt the pump and it didn't work. New Yamaha OEM pump and it's running again. It's more expensive but well worth it.

thanks for sharing, I am tempted to fix it up nice
@@dirtniron yep, definitely tempting especially when you get a good deal and are handy with the DIY stuff.
For three hundred dollars I would spend some time on the pump. I would try pushing air through it in reverse flow direction to clear out obstructions.
What a sweet bike and Im sure you got a great deal on it!
yea, pretty good
Very creative testing solution Rado!
glad you like it!
Yeah, because everybody has an extra tank and pump and an air compressor laying around for just such an occasion...or you could just buy a cheap fuel pressure gauge. LOL...
Fantastic explanations..keep bringing them my friend
thanks, will do!
Running your bike with low fuel volume all the time will damage the fuel pump as it's lubricated by the fuel. Keep the tank full!
You can do it!
Good job on the fix! Where do you find bikes like this?
online always, craigslist, marketplace, offer up..
I love these type of videos I want more
Nice fix, definitely keep it but supermoto it 🙂
eBay pump (kemso)has outlasted 3 factory pumps that burnt out on my 2017 500 cams port work exhaust makes ridiculous power
I rode a WR450 once ... holy crap, its beastly...Way too much for around here, I'd have to sell it.
Great work 👍
