Had to replace mine at about 20hrs on bike, 18 te300

I still like my kehin on my 250 better than the mikuni it came with even after the jet block gasket and jd specs. Mikuni is still better than tpi/tbi in my very biased opinion. No fuel pumps or oil pumps for me, yet anyway.

Its not about the head getting "sucked in" (Whatever the fuck that is) Its about galvanic corrosion. Pro tip for al the reservoirs on japanese bikes with "philips" head screws. Its mot a Philips head, but JIS. Japanese Industry Standard. You can get a special JIS screwdriver

I would never bring a dirty filthy bike to a mechanic, never!

Buy some vampliers. Youre welcome.

Hi, your videos are great. What Feeler gauges do you use?

Might I suggest doing this with a left hand drillbit so that you could possibly extract the screw as you drill.

big size gentle tapping into striped head and out or a bolt remover so much quicker

Plus the cap is Alu and the screw steel which is a bad combination for seizing up.

ALL torque specs are to be dry. As soon as you add loctite or some sort of lube you are over tightening the screws. Think of it as anti-friction, torque is the friction building up on the threads of the screw and hole.

Far from cheap. Gosh dang

At what hour do u suggest rebuilding 300 tpi. Thank you.

Thats great info Chuck. I currently have a 2023 YZ250X. The PWK38 is an amazing carb when dialed it. Recently though i have been experiencing a “surging idle” when going from WOT to idle in a quick fashion. Seems to be when the bike is very hot (not boiling over hot) in extremely tight single track. Otherwise runs exceptionally well. Have been running the same jetting for 2 seasons without issue. Fresh OEM top end 15 hours ago. And a total of 85 hours on the bike. Definitely seems like a lean surge but doesn’t do it until the bike is very hot. And also don’t have a hanging idle. If anything I’m a tad rich on the bottom end. I was thinking a possible air leak but you would think if that was the case it would consistently have the issue 🤷🏼‍♂️

Yep n then your a screw short n screwed pun n no pun

Pro tip. Don't strip it in the first place

Finally got around to watching this. Great explanations and I agree there are a lot of misconceptions on this topic. I have a number of ride buddies around or over 10:38 200# with stock springs on Austrian bikes, content with mediocre, harsh suspension performance from too much preload to get sag and no balance. Whaaaat?! Is ignorance bliss?😮 Well, it is cheaper until you get tossed on your head.

First off, just get a screw extractor kit. Couple of dollars and you got one. Next, put some copper grease on the screw threads next time you screw it in. It withstands the higher temperatures and it will keep the bolt tight and snuck while still being easily removable for future maintenance. Every mechanic or homes mechanic should have some Copper Grease, White Vaseline and lithium grease laying around. With those 3 you can tackle 80% off lubrication needs

Like to see the coolant level when the bike arrived at the shop. That temp sensor looked deformed.

We must also remember that heat treated rods are also a thing so always check its not a factory thing (as some blueing can be totally fine) - now if the bearing is blue too then its probably f*ked

Thank you for telling us about the blue mark!. I didn't know that.

Lack of oil

Overheated bad. Maybe lean? If it got the rod thst hot?

What’s the normal amount of ft/lbs for those clamps? I’ve been looking all over the internet and can’t find the specs

Worse situation the screws aren’t SS and the threads corrode ruining the whole master cylinder!

RK Tek head will produce more heat, that mixed with a lean tpi tune would be my guess.

That is one good looking bike. Looking forward to see your ride reviews on it.

Cool trick! Got any tips for if it's also stuck due to corrosion?

An actual good video of a dirtbike. I love this channel and the reels on insta which is where I came from.

You Gould get a swivel tip brake

Love what u do. I'm a master tec for cars. I get stuff several shops looked at and won't run. Lots have non flammable liquids in them. Like diesel, water, crappy old gas

Little bit of anti seize on the taper would help.

Thats caused by negligence from owner, not just ethanol alone. I have used 10% ethanol in motorcycles, I add fuel stabilizer to full tank of gas. Store the bike in dry garage, then run engine once a month which also keeps the battery charged. Bike runs perfectly without any issues after storage. Avoid storing bike &small engines outdoors helps on increasing fuel lifespan, also reducing corrosion issues. Ethanol is powerful cleaner so when you use ethanol fuel for first time, you should check that theres no dirt in the fuel tank, also the fuel filter is not too old and dirty because if theres there any dirt then ethanol will be cleaning & trying to get the dirt into the engine's combustion chambers. But the carb's jets are too small so dirt gets stuck to the jets. Mandatory ethanol blends to gasoline is a good thing despite it annoying some people because it reduces amounts of harmful tail pipe emissions at urban areas.

Great video! Interesting last name. I'm guessing we may be related in some way.

You wear Sandals ? OMG ehat next a sex change

The petcock probably full of gunk to

Was it brand new? Any idea why?

Another asshat using power tool on clutch basket.

Hey what’s your way on installing crank bearings when the seals can only be taken out/ installed inside where the crank sits

We have it in California also. After rebuilding the dual cards on a 1986 Honda XL250R (really small jets), which are really hard to get out several times. I found that if I drain the bowls after every ride it usually starts right back up. Another option is race gas or aircraft LL100.

I'm assuming that vent hose to the airbox is just for emissions

Are you familiar with tpi injector relocation block which moves both injectors? Do you think its worth it for my 2022 ktm 250 exc tpi?

Hey Chuck, what's your go-to brand for shock bearings/bushings? Do you usually go OEM or something else? I recently went to replace a lower shock heim bearing on a KTM 300 PDS with a kit from that Moose Racing brand and the machining of the bushings was far enough off that I actually couldn't fit the shock over the bushings. Broke out the calipers and found that their bushings were somehow like 20 thou wider than OEM when installed. Made me re-think buying aftermarket kits for that kinda stuff (maybe I just got a defective one though...)

I just picked up my first 2 stroke ktm 65. Does this bike just not like going slow????

Chuck, Where do you buy your bulk carb hose?

Always try new gas if it’s been sitting for awhile before cleaning carb

That 2 stroke sound. So beautiful. ❤😂

i’ve damn near put a wrench through a window trying to do this thank you

What was the logo?

How can anyone have a dirt bike and not know how to do simple maintenance?

No sound on the right side :( 🔇😢🔊
