Would it be possible to fix those lifters when still in the engine ? Like putting a weigh on it ? I' m little afraid to take out the camshafts, I'm not a mechanic. My lifters in a A4 B5 1.8 20 Valves have different resistance when pushing them; some are soft an move easily 2-3 mm, some are hard and cant be pressed at all, thats at the Inlet side; the outlet side with bigger lifters are all hard. The engine was working well till noe, just the lifters make a typical metalical hammering sound for 2-3 sec. after starting (allready put 10W60 , otherwise the noise would be there allways.) I thought it was a problem of the old oil pump, car has 220.000 km now. Thanks for your advice!

Very well explained, thank you !

Anyone know if the shift drum itself has standard or reverse threading ?

How did that hold up and where did u learn that from I just got a kx and the shock is bad,,thanks

Hey, great riding! Ist this with the new shock you installed? Planning on doing the same!

80 thousands is the recommend minimum clearance. You should of checked the clearance with the camshaft as well. I'm assuming it didn't hit the camshaft but they do come close and they will hit on some builds.

Your original pistons were flat tops. They generally have valve reliefs on both sides so the piston can be installed in either direction. Basically their made dummy proof. A domed piston can only be installed one way because of the dome. So only one side of the piston will have a relief. If it was me I'd get as set of open chamber heads and have the block decked to zero you'd make more power doing that.

Good!!! Bro she came out absolutely slick

I'm a Harley guy but I'll tell ya dude that is one SWEET scooter!!!!!!!

Looks fantastic. Ride on. Subscribed.

Nice

Polishing cases is an art and there exists no easy or quick way to do it which is why when done right it is so sought after. It is labor intensive and tedious. Begin by vapor blasting with fine glass beads to clean everything. Then you will cut up credit cards to various sizes to cut the aluminum flat and progress from 80 grit all the way up to 2500 grit using a cross polishing method. After that you will use rotary tools with felt bobs and mothers to fix any micro scratches and then again with flannel wheels and soft cotton rolls & mothers to give it the final shine. Cerakote makes a new high temp polished aluminum clear that is also gas & solvent proof that can be used to protect it. Wax is the old method that works as well but requires more care. Bate aluminum will oxidize quickly and the protection will save you lots of headaches. Honestly you did an OK shade tree job and many that have tried to tackle such a project find out real quick how hard it is. The details are what matter and they are the hardest to do. A professional job on that case would require around 20 hours of labor and at a shop rate of $30 per hour you can see why it's so rare and only the big boys and show bikes have it done.

Just ordered some off Amazon for 2.8 volkswagen 30valve, and the box had oil all over and none of the new lifters could be pushed down,

279 casting are L29 100cc closed chamber heads

There also open chamber pistons

Domes are measured in cc

Good job keno i see the ramp holds the weight of you and the bike. Keep doing what you love to do. Great Job!!!

No, plastic slides or housings are not the problem at all… the reason for the wear is a dirty or modified air filter letting dust through… the dust between the slide and housing is what causes the wear… if you replaced your air filter at the specified intervals, this wear would not happen…! However, there are other issues with these carburettors, design issues in my view… if you place the long ‘jet needle’ down the centre of the slide, you will see that it hangs at an angle, and not straight down… inside and at the bottom of the slide there is a small shelf built into the slide causing the the white plastic washer on the needle not to sit flat… what I generally do is grind a flat on the white plastic washer allowing it to sit flat… but because the needle hangs at an angle, it wears the top of the ‘needle jet’, otherwise known as the emulsion tube… if you look carefully at the hole at the top of this emulsion tube, you will notice that it is no longer perfectly round, but oval… over time the bike is starting to run richer and richer… this is the reason… by the way, the needle also wears… so you need to replace both the needle jet and the jet needle… use standard genuine Suzuki air cleaners… the other problem with the air cleaners themselves, is you can’t see when they’re dirty… the recommended interval is replacement every 6,000kms…

Where can I find some bags like that? I have some 18 wheeler cab mount bags that I might try because they're small. Awesome video man!!

Wrong pistons for your heads

So what you're saying is it okay to buff them and put them I definitely would not use you mechanic

Thanks for the video. I love vintage motorcycles and started up jetting since the factory is after mpg. The bikes just run better a little on the rich side not to mention cooler too.

Just install a 90 degree valve stem and do it right the first time. Problem solved.

The money you spent getting those pistons machined and rebalanced could of went towards a good set of aftermarket aluminum heads that would of worked perfectly with those domed pistons.

I don't see any problems with this parts

This is bullshit, the lifters can't expand more than its limit. The engine is obviously off when taking off the cam shaft so how can the lifter get over extended anyway.

Aaaa ,ma eee ? Are you also bleeding a new lifters ? For vw when you bying new lifters then are already hard and ready for install . Manuel for vw doesn't say anything about bleeding lifters . Second stuff ,that is not a real way to bleed lifters .You needs a special players for disassebling that kind of lifters . Vw nummer pbwf 56821.😏

Thanks for sharing . I have Audi also and must change all lifters . Must I bleed a new lifters also ? Thanks for answer .

Great video! Thanks for the information

i have seen someone pulling the center tip w plyers clean them out and reasemble.

My gears started to change really ruthly culd that be a problem but it changes ruthly when bike is running

you need a old set of heads those gen 6 heads won't work ,you need early 70's head ls5 or ls3 heads ((not small block modern day LS heads) old 70's big block LS 5 or LS3 OPEN CHAMBER 105cc

Very helpful, thank you

What do all those wires connect to? You failed to show this?

I have do the same in my dirtbike yesterday. You save me 40 euros. Thanks!!! My problem was in cold engine... the clutch starting like sick. Now it works great. Thanks again!!!!

Wouldn't the WD40 have a negative effect. I would just clean them with thiners, wipe off, lightly coat of engine oil, and then install

How did this motor turn out. Thinking about doing mine

Thank you this helped a lot

Hey where can we get the housing sliders?

Was just curious if you are running standard 454 piston with a stroker crank you need a piston that is made for the increased stroke the pin will be further up the piston

Good video ,make more videos

Big blocks pistons with domes are either for closed or open chambers. Open chambered pistons can only be used with open chambered heads while closed chambered pistons can be used with both.

You chave to run an open chamber head bro. You can't run closed chamber heads. You're going to have to go with open chamber heads my friend. Your bottom end is fine.

The term is valve reliefs not release. You will have to fly cut the Piston domes if Summit will not exchange pistons. This is why you should measure everything on non stock applications. And this is why professional engine builders charge so much. Alot goes into building an engine correctly!!!

That is not a 2003 kx250. It is a 1999-2002 kx250 lol

Put that thing together the best way you think possible. Run it Let it grenade. Take it apart and figure out what went wrong Only way your gonna learn. Expensive but the best lessons learned are when you spend a lot of money on it and get nothing from it……except experience 🤣🤣🤣🤣

That looks more like a gen 5 block... vortec heads can only be run w flattops

Yes it help me alot thank you.

so it was a bad rectifier?
