We had to take a break from youtube for a couple weeks to clean up a house, but now we've got that mostly under control. In this video I discover a possible solution to the KDX200's engine trouble. Sorry for the delay.
I highly doubt that the carb seal was the issue but I still think like many others that you won't know if you fixed it until you clean the exhaust out, there's so much oil and gas and sludge in there that even if this thing ran perfect its probably spewing out smoke and gas and oil for quite a while until it cleared..
i like this channel allot. i like that you show the failures too (you learn something every time so truly not a failure) but its good too see the ups and down keeps it real and honestly helps the rest of us remember things in the event we run into them as well as knowing what to look for. you guys rock keep it up!
Have you cleaned that exhaust out? Drain the gearbox oil flush it out completely then try starting it, as long as you don't ride it there shouldn't be any risk to the gearbox, I'd put a Buck on it being the crank seal though and just go ahead and change it
Ive watched all your videos and I have about a 70% understanding now of a motorcycle compared to my 10% when I first stumbled upon this channel.LOVING EVERY VIDEO
Holys Moly I know this is an old comment but same here I stumbled across this channel and know so much about carburetors now .. Like I'm in school or something!
Might have fixed the problem. Most 2 strokes will shoot out that black spooge stuff”unburied premix” when the bike isn’t getting ridden hard enough. Also might want to check the packing in your muffler could be soaking wet.
You need to repack the silencer before you go deep into the engine ... as bad as it was running before that silencer has GOT to be clogged with wet oil/fuel...there are really only 3 things that can cause raw fuel to blow out like that , #1 would be compression, #2 would be weak spark , #3 would be a leaking needle/seat in the carb.. good luck
Team Jennies Garage, not only do I get an education on small engine troubleshooting. The friendly banter and interplay between you is a joy to see/watch/hear. Cheers to you :) many thanks and continued growth and success :)
I clicked on this video (because you ALWAYS watch a new JG video immediately when you see it) and just realized an hour and a half has gone by and I've watched like 17 of your old videos that I've already watched. I love Jennies Garage ❤️
I grew up too poor to pay attention. When I was 13 I worked for a guy for two months to buy a busted-arse atc 110. I learned to work on it and resurrected it and that was my foray into motorcycle repair and building. That was 30 years ago. Since then I've acquired and rebuilt many motorcycles. I rebuilt my CRF450R last year, top and bottom, and I'm currently rebuilding the carbs on my CB600f. It's kinda cool hearing the background of how you learned much in the same way. Necessity is the mother of invention, but also education. ✊
I really like your videos, Jennie's Garage. I love dirt bikes and your rebuilds on motorcycles make me so interested in the rebuild videos. I am so motivated to watch them. I am passionate about your videos with a sense of enjoyment. I find it a really good time to sit back and watch an amazing show such as yours. I learn a lot and find you and your family are really neat.
A new red ruckus seat for the wife and a cool driver arcade game for the kid. No matter what you thought was the problem with the Kawasaki and what the actually problem is, you can do no wrong. :)
Ive been away from youtube for awhile & have 0 reason to go on here but i love these videos. Your smart the way you diagnose thing & you give some interesting tips I personally would nvr think of working in my bikes. Thanks for awesome content & keep it up!
my 98 has had that seal problem for couple years,i finally ordered one and am installing tonight and water pump seal,mine ran fine other than it smoked more than it should and lower gas milage,rebuilt top end bout 1000 miles ago so i hope it makes a difference,my kdx is highly modified and street legal and i still ride trails and sand,im also swapping 2005 kx250f forks on it tonight as well,i might gopro it and start a channel soon
Brother man you and your wife just make my day everytime I see your video so when I'm in a bad mood I just watch one of your videos and I subscribed keep on with the videos and definitely keep on smiling and laughing watching out of Tallahassee Florida
Repack the silencer and clean out the expansion chamber.check the reed valves and make sure they are sitting flat on the cage,if not,replace them.also check the float level,the float should sit parallel with the carb body,if it's too high,your getting to much fuel.one more thing to check is the choke,look at the bottom of the plunger,if the rubber seal is bad,it can leak fuel past it also.hope this helps!!!
I've been watching for a few months now and I love your videos. You remind me of the old 3dmachines before he turned his channel to trash. These are the type of videos I love to watch. Keep up the good work!
You're getting it figured out. It seems as you're similar to me. When I have a project going it absolutely consumes my brain until it's done. I rebuild it over and over and over in my head. Then when I have an epiphany in the middle of the night I have to run to the garage or I wouldn't sleep anyway. Also, please clean out that exhaust and repack the silencer when you get your fuel issue fixed. I'm sure you already know that though.
The exhaust needs a good hard run to clean it up, it will shoot oily gas out for quite a while after running cold and rich. Take it out and beat the snot out of it for at least 45 minutes then rinse and repeat test.
I too do motorcycle and scooter work out of my own home garage and would someday like a KDX plated bike. Keep up the good work. Very entertaining, motivational and interesting. In my experience, once cases are split, might as well inspect all bearings, replaced as needed and replace all seals. Seals are cheap. Good luck, and congrats on the CA plate, BRAAAAP.
Again I was wondering where you were. Another try didn't work but keep going. You wife's voice is so pleasant to hear behind the camera. Nice that she gets something too.
An old Yamaha Race bike builder here. ( family owned a dealership who built Freddie Spencer's early racers before he got the Honda factory ride.). That engine is not breathing. Here's where I would go: 1. Clean that pipe out , reinstall it and run it hard until it's no longer loaded up. ( with a fresh plug in it).., 2. Probably not a crank seal. It wouldnt spew fuel if it was. Only oil., 3., Oil/fuel tank mixture too rich?? , 4., Timing?, 5., Metering Needle set too high ?., 6., Bent reed valve, if any ? Maybe. Probably not. 7. Remove air cleaner to test ( for now). I bet that exhaust port is 1/2 the size it needs to be, due to carbon. Hope this helps.
All 2 strokes smoke a lot on a cold start up. Mine would do the same thing and foul out a plug every 2 hrs.I switched my premix oil to amsoil saber 1.5oz per gallon is 100 to 1.Yes I know that your thinking but since the change to amsoil I have put roughly 50 tanks of fuel through it and had the same spark plug for 3 yrs and once warmed up the smoke problem is completely gone.
A good way to check crank seals, is to remove side covers on engine, take spark plug out, then fill with mix gas, while piston is on bottom of stroke. Check for gas leaking out seals.
Make sure that the float height is correct at the specified carburetor angle in the manual. Even if the float looks parallel with the bowl, it only takes few degrees to make your engine run rich.
Pilot jet:42 Main jet:155 Needle: Sudco CGK 017.018 This will get you CLOSE but you have bigger problems with those seals bro, but you already knew that. I forgot about that gasket in the carb. I bought that exact same security bit set at 6:43 for doing this haha
Only thing I think it could be is that the float is no longer floating, which makes it act like a bad need valve and seat problem. So many of these bikes were made long before anyone thought they would be putting so much ethanol in the gas we buy which is very hard on the older fuel systems. I have to run Seafoam in my scooter to help prevent damage from the ethanol. In other words, either the float has pinholes and fills with enough gas to make it not float or, it has soaked up enough gas to not float if it is a solid type. Good luck. Oh, you need to give Jennie her battery back, ha ha.
I just stumbled upon your videos and I was hooked. Bikes are like water bugs it takes a dandelion and a cloud of rainbow dust to scuba dive in a cold volcano.. makes no sense lol
Long time viewer, first time commenter. I grew up riding motorcycles and working on them with my dad in the garage (since I was 5, I'm 33 now), so I enjoy watching your videos of fixing up bikes. This one got me though, you are wearing exactly what my dad would wear a lot of the time in the garage. Ripped up jeans with grease and who knows what, dirty shirt of the same description, and the same maroon zip up hoodie. Not saying I look up to you as a father figure or something, just made me laugh. Keep it up, sir.
That bike has an onboard oil injector, check to see if it has been turned up too high. Also check to see if the float level is good, if the float level is high, it will flood gas into the motor. Also take the packing out of the silencer, it has to be soaked with gas and oil. Cheers from Tokyo Japan
The Yamaha 2-stroke I have has an oil pump that can go out of speck and just piss oil into the intake. It smokes like a chimney when that happens, but can be calibrated and fixed fairly easily.
Have you tested the float in the carb for leaks? Get a clear container of gas and push the float down into it so it is completely covered. Turn the float over every direction and see if any air bubbles come out, or you can feel any gas sloshing around inside the float. If the float leaks and fills with gas, it won't float, won't close the main metering valve, and cause an obscene rich condition.
maybe the air pressure in your front tire could have possibly change the angle of the float in the carb, which in turn keeps the gas flow to enter into the motor at a high rate of speed, if my calculations are right the rear air pressure is also off adding to the extra fuel into the motor, I could be wrong also, but just a theory. Merry Christmas!!
Mate something worth thinkn about is the fact that the KDX may well have bn running rich on fuel and possibly gearbox oil as youve diagnosed ....but what im suggesting is during this running time it will hav filled the expansion chamber and tailpipe with residual oil/fuel....so i suggest you clean the exhaust as best you can ..eg ..wash it out with solvent and/or burn it out.....then when ever you alter the carb etc youl see a more accurate tell-tail out of the exhaust....also sometimes the internal baffle tube in the tailpipe can dislodge or break essentially blocking the flow path (partially) n as a result making the engine drown in its own burnt and unburnt gases......just a thaught worth lookn into .....Luv ur videos n keep up the good work ...n please squeeze cameragirl for me cas she's just so god damm adorable...n youre lucky to have found her ..lol ...cheers
New here so probably already been covered but seen a simular situation on a ride on mower where fuel needle was leaking due to dirt causing fuel to seep into engine and mix with oil, smoked like hell, changed oil, cleaned needle and five minuets of hard work later the smoke was pretty much all gone. Think on the mower engine this had also caused the oil level to rise so it was blowing this fuel oil mix out the breather into the intake
Man, you guys are GREAT!!! Stumbled on your channel ,again and have laughed for 2 days solid.I have seen some of your older videos but they are more " business ".However, I love the more recent ones with some goofin around, but still great info.I'm a life long dirt bike guy and now at the age of 51 still love riding and fixing up old beaters.My three sons and I have about 4 miles of trails and and track on our farm and ride often as we can.If your bored, you can check out some of our videos,low budget and not that great,but you see how we roll.Thanks for sharing your knowledge.
Your back that's great. Now any ideas why my 1964 trail c90 won't kick over? It kicked over once today got ready to ride it and it stoped won't kick over again darn.
Another great video on the kdx. What the heck could be the problem?? Please update us soon. P.S., Your wife needs a red jacket now to ride the ruckus in style 😊
When you say the jets are correct do you mean they have the right number stamped on them? They could have been drilled (reamed) out. But I go with the fouled up muffler idea too as this could have been the result of the drilled out jets.
Depending on your state or county landlord tenant laws, you may need to write an abandoned property USPS certified letter to tenant's last known address and wait the statutory time to lawfully keep that stuff. This notice of abandonment may protect you from a tenant coming back and claiming an unlawful lockout. Oh and change the locks. Remember to do background checks with next tenant.
Great videos you too, I like your Chemistry. I have a suggestion, I know you've made more videos on the kdx since this one, but my suggestion is to clean up your garage and build a workbench. Just saying, what do you think?
Take the pipe and silencer off, take packing out of silencer (don't worry about replacing packing till you figure this out), clean both with mineral spirits, air, long screwdriver, whatever, you'll be able to tell when they're clean. They shouldn't be very heavy. Run your fuel/oil mix at 50:1 with some quality pre-mix oil (I prefer yamalube 2R). Bad crank seals would cause a LEAN condition.
Did you check the float and make sure the float is set right and that the needle valve is closing at the right level also did you replace the needle valve make sure your not leaking there cauae bad needle valve or improperly adjusted float cast cause rich run condition.
Test your float needle seal. If it isn't stopping the fuel when it needs to, the bowl can overfill, leak past the reeds and accumulate in the crankcase. The expansion chamber/silencer may need cleaning out also. There may be an accumulation of premix in the crankcase. Just my thoughts and I'm just a lowly shadetree mechanic. I love your videos and buy your wife a new reliable battery.
Im sure that oring u put in helped some but i think you just need to go with smaller jets to get rid of some of that gas and i think itd be wise to change the crank seal if there was oil in magneto it means its gotta be changed
Did you ever check the spark plug? Highly doubt that is the problem but they do foul a lot on 2 strokes...if it was the plug it probably wouldn't start at all but after all that oil and fuel running through it then it probably wouldn't hurt to replace it anyway
perhaps it could be that the ring gaps need to be at half and half. or at least 1/3rd from the other at being center. if the gap in the rings are in the same place, it will allow oil to bypass to the top of the piston head. OR the bottom cylinder could have a warp in it , to '' just '' allow enough oil to get tot he top of the piston. OR the valve seals ( if it has any) could have popped off their seat, causing massive oil in the exit of the exhaust. hmm, also for every engine, there has to be pressure control to allow the constant movement of the piston. take the exhaust off, and drown it in kerosene = k-1 to wash out the oil, shake it every 30 mins to move the oil out of it. after 4 or 5 hrs, remove it from the bath drench with gaas , let dry,shake it every 15 mins for 2 hrs. so give the gas has time to dissipate.... after that lay a small line from the exhaust 5 feet away, light it. let the remaining fumes burn off. make sure you are out side and away from a small get away. doing that will keep you from purchasing a new muffler and exhaust. as for the ruckus ... those are nuts ... not bolts...bolts have a shaft with external threads...nuts have internal threads without a shaft. awsome vlog!!
