Crackin the throttle on anything fuel injected while trying to start usually does more bad than good, they’re mapped to start at closed throttle position
I've said it before and I say it again... For non start - quickest to determine what's not working. Disconnect any kill switch. Pull plug, compression test, while plug out test for spark, if ok drop fuel down plug hole.. For those without a compression tested just pull plug and drop some fuel down.. If she fires then you know there's compression and spark and most likely carb / fuel issue. time spent on many outboard and bikes and this is first thing I as Always do it non starter 👍👍
For future reference to test rings just take off oil filler cap put ya hand or thumb over hole winding bike over and if you feel any air coming out rings are shot
Tip, when removing the large slotted fasteners that you tapped with a screwdriver and hammer, either find the largest screwdriver you have, then try and use it as a screwdriver not a chisel, or clamp a suitable coin in some vice/mole grips and remove it without any damage. :) Nice vid btw :)
A recent fuel injected bike is always going to be more hassle. I wondered if it might have an immobiliser that would stop injectors firing. Still surprised that it wouldn't fire gas left in the cylinder given it has ~90 psi compression. Good find on the stuck rings, wonder if ring lands have closed up as well.
1 pro with a kicker: you’d be able to tell ASAP. I bought a 03 ktm 250 and I started it with my hand 😂. Good work man. You’re very methodical and it pays off.
4500, bought a new crz 250 for 5k. But glad you made this video. The crf looks alot like my crz. I've only worked on predator motors and my Suzuki cruiser.
I wish that Honda would offer the option of watercooled or air cooled engines! Like the older BULLETPROOF XR MODELS that I now wish that I had never sold
Still watching the video and heard you mention new ignition. On my gsxr i got it non running same story about the ignition. Even though it had the diode is still wasn’t right, I replaced it with an oem ignition and it fired right up. Always love the videos!
I have the 2013 model. Had pretty much the same problem. Being newer and computerized couldn't figure it out. Took it to the local Honda shop for more in depth look over. Should of thought old school. It was the spark plug. Even though I had spark and everything. It was just the spark plug.
On the leak down test some leakage past the rings is normal. You should have a leak down gauge. Fuel pumps runs does it pump. Injector pulse test. A noid light tests pulse. Great video.
Dirty block carb is my guess 🙄 before watching video? Who would have guessed the piston rings, but i would have thought they would have been ok. But they are 8 years old. Thanks for your great videos.
You need to use a lot bigger flat head screwdriver to pull those covers off so you don't butcher them. Something that has no play when it's slotted in there.
Great video but I wish you would have try a brand new spark plug before you took it all apart I've seen spark plugs spark like crazy when tested on the side of the engine but in the cylinder under compression they won't
I don’t know if you ever synced carbs because you mostly deal with single carbs but that would be an awesome lesson you could help some of us. You explained the valve Clarence pretty well. Thanks and good videos again!
@@theyzoomers dude I run a motorcycle shop, not everyone understands syncing carbs and obviously people watch his channel so it would be a “ learning “ video to get more views to help him out as well.. so why lol?
Great videos! Have you ever thought to wash stuff off so the sand and dirt isn't falling into the engine, just a quick pressure wash would go along way
I had a similar bike with the same problem. I had a the incorrect / bad spark plug. Local dealer did not have one ordered one from eBay and she fired right up.
My 2009 carby model 450X was doing exactly the same thing..completely dead..turned out to be sparking but weak..replaced the plug with new one..problem fixed.
if you get a crf230l or 230m id love to watch ya work on one.thanks for all the teaching you have tought me,i love watching your videos.i know this is an older video but ehhh whatevas have a good day.
I’ve literally seen every single one of your videos over and over and over again Their so entertaining!! I could tell anyone any part of the video and when that part happens for every single one of your vids. I rebuilt my rm250 motor just from your videos! Keep up the good work man I love it!
on fuel injection bikes at least ktm they have an internal tank fuel regulator. if that goes bad it recirculates the fuel back into the tank. visually you will see fuel coming out of the injector but will not have the right pressure. inline pressure testers are key on fuel injection. had very similar issues and it was just the fuel regulator stuck open. not saying for this bike but always a good test that goes hand in hand with compression and leak down before ripping into the bike too much. might help someone on here at some point
Honda did say they want to start adding anti theft measures in place like cars were u can’t use a offbrand ignition you would need to provide ownership for a new ignition or key because of that major dirtbike theft that happened recently at a dealership in mo theifs stole whole new shipment of Honda dirtbikes that haven’t even been in the store a full 2 days
I see a slip on aftermarket pipe , but no electronic jet kit . That's most likely the cause of the fried rings to begin with . She definitely got a little too warm . Also , that wasn't an aftermarket air filter , and it was missing the intake boot . You have to re-jet for a pipe , and get a better air filter or risk toasting your rings .
Soon I’ll be going thru a lot of this same stuff myself…got a 2016 husky fc250 that died while idling after about 2 minutes from cold start, hasn’t fired up since…hoping it’s a spark plug or something simple, I’ve got less than 2 hours of ride time into the bike and it’s cost me well over 5k… motor seemed to start easy and run strong right up until it randomly stalled the other day..
That thing sounded the same with the sparkplug in as it did when you motored it with it out. I know the CRF450's use a decompression device and cranking pressure is about 65-80 psi.
When you first pulled out the spark plug you mentioned that it wasn’t wet. Why didn’t you continue down that road when you found that it sparked but wasn’t wet?
Hey I have a question. I just replaced a water pump seal on my 1993 Suzuki Rmx 250 and when I started the bike cool began to leak from the gasket by the water pump, any idea why it is leaking. And no it’s not from the weep hole.
I nearly bought one, but there was so many for sale with super low mileage, I found out that they a so weak people returned or sold them after weeks buying.
Hi I watch all your videos and always leave a like and iv been going over some of your old videos and some time ago you didn't know what to do with an old 1990s xr250r you split the engine . iv a xl250r 1985 uk road legal but for the life of me a cannot get it started iv put new piston rebore new values lapped in new valve stem oil seals new clutch plates a complete strip down and powder coated new rear suspension linkage bushes were needed new wheel bearings front and rear new enduro tyres can you help
My DR350 sounds exactly like this and everything checks out OK like this bike. I wish he would tell us if he got it working and what the real problem was. I'm not sure he found the real issue.
u know I had an 2005 XR650L with like 3k miles and it would not start unless you pressed the start button for 2 seconds then let off and wait 1 second, and pressed it again for 2 seconds. no throttle at all during it. if you did it in any other order or timing it would refuse to start. Even the guy i sold it too emailed me asking if theres a trick to start it? I told him the method and it fired right up.
Hey Joe. I really enjoyed learning about the leak down test. I've never heard of it but, seems to make perfect sense. I do have a question about the compression tests. I don't understand why the throttle being open or closed would make a difference. Wouldn't that just affect the carburator? How would that affect the compression reading? Thank you for another kick ass video!!
This bike is fuel injected but either way, You need to let enough air in with the throttle open to make full compression. If it's closed then you'relimiting the air. .
you already confirmed the compression was good...so valves will be good as will leak down test...i wonder why u went that route. looks like timing of the spark, will it have crank/cam sensor, or some whitchcraft going on in the cdi?
I’ve got a 14 crf250l also, it currently is idling super low, around 700 ish rpm, but it is supposed to be idle at 1450, do you have any suggestions on what to do? I already shimmed the valves and it didn’t change much.
Hey I have a bike that I’ve brought to every shop in my area and every single one of them are making me pay a bunch of money for the labor of inspection it and slapping parts on it and every single one has given me my bike back without fixing the issue I wish I could bring it to you cause I’m fairly certain you’d figure it out with easy but maybe not who knows

Good job on diagnosis Joe. The new bikes sure are compact, complicated and sort of delicate compared to the older stuff.

Yeah that was hard to watch
Right lol 😆
Hahaha I cringed and had to look away
Use a coin in the slot on inspection covers and turn the coin with pliers, vice grips or a shifter etc. You wont chew out the plastic or even mark it
who cares about plastic marks? ....whats wrong with you?

He’s a hobbyist not a mechanic for sure
I agree. Wash the thing first.
ANY dirt or even sand that fell in would be propelled out the exaust within about 2 secs after startup! ...you guys worry too much.

What would cause the rings to stay/stuck compress into the piston like that? Is it from sitting or just worn out rings? Thanks
I believe from sitting
First of all that's not a good and reliable test unless you have a leak down tester , the other thing you need to make sure both valves are closed !
What about freeing up the rings, cleaning out the grooves and try cranking it again?
When you first pulled out the spark plug you mentioned that it wasn’t wet. Why didn’t you continue down that road when you found that it sparked but wasn’t wet?
curious rings stuck but compression was spot on .
Xlnt video, keep up the fire content 💯
Thanks sir, I learned a little from this one. Keep 'em coming!

Hard to believe it has perfect compression and bad rings. Any followup to this?

I don't understand why the throttle being open or closed would make a difference. Wouldn't that just affect the carburator? How would that affect the compression reading?

It only really effects 2 strokes with standard style valves
This bike is fuel injected but either way, You need to let enough air in with the throttle open to make full compression. If it's closed then you'relimiting the air. .
Devin Lawson. Thank you. That seems to make some sense to me.
You didn't learn too much from this leak down test because he did it all wrong.
LK LK What do you think he did incorrectly? What should he have done instead?
I wonder what initially made it overheat oil or coolent, you may find another issue once you get it running
I'm pretty sure it was just from sitting for a long time
Valve clearences, exhaust if not adjusted Carb/ecm for proper Air/fuel mixture and also It is a Cali version with a fume ressovoir.
you already confirmed the compression was good...so valves will be good as will leak down test...i wonder why u went that route. looks like timing of the spark, will it have crank/cam sensor, or some whitchcraft going on in the cdi?
Can we get more dirt bike videos 🔥🔥
Nickle sleeves those.
Cool video!
Check for intermittent and weak spark from bad connections.
What has me puzzled is that it's putting out almost 90 psi with a decompression valve and stuck rings.
Awesome job. Isn’t that illegal for a Honda?
Awesome work. Do you charge for this type of work? Or is it free as it’s content
It's free if you bring your bike to him.
how many miles did this bike have? these things are basically bulletproof haha
I have watched enough vids to where I knew he was gonna say @6:20 "yup its ahhh sparking pretty good" hahahahaha

What would y’all do in that situation it’s a 2020 and not even the dealerships or small bike repair shops can diagnose it what do I do
They make a tool to take off the inspection covers , so you don’t have to beat them with a screwdriver
