Valve Removal & Installation Method 2 : Specialty Tool (Very Easy)

In 3 videos I show how to remove and install valves and valve springs three different ways on scooter or motorcycle or other small engine cylinder heads. This second video shows removal and installation using a specialty tool.

49ccScoot DIY tutorials are the real deals. simple,clear and easy to understand for a layman..

[@88Frank]

I wasn't sure whether to pay for a head rebuild but you've given me the confidence to crack on so thank you for this video!

[@lancejonesmusic]

This tool, I got for about $15 on ebay. WOW! WAAAAY easier! Thank you! I was having a hell of a time using the tool int he previous video. Folks, get yourself this tool! Night and day difference!

[@lawrencelimco]

I just rebuilt my engine using this tool works awesome.

[@mahmoudmarzouk2680]

Very good engineer ❤

[@ryckryckman8176]

Dude I tried for 3 days to get retainers back in. this tool worked the second time took 5 mikes and worked the first time on the other valve! I'm toasting a drink to you right now. thanks

[@thomasdsmith7678]

Thanks. For 40 years, I have done that with a deep well socket (about a 14mm) to "pop" the keepers. The installer can be made with a 1/4 drive deep socket inside a larger 3/8 drive deep well socket. Use a 2 inch hole saw to cut a 1/2 thick wooden plywood "puck" to hold the valves in place (instead of the rubber knob). Cost:free.

[@monarch29balisongs]

Perfect video thanks man

[@rembu7961]

nice one bro thanks

[@RP-dv3pw]

Fantastic “how too video”.

[@jasperdomacena6491]

ohh wow that just makes things easier! awesome tool before that, I just use a deep socket and a "sorta hard" plastic sheet to keep the valve keeps aligned and fall into place when I push on the springs might take 1-3 tries but it works 🤷🏻‍♂️

[@mdsoto3893]

Thank you very much buddy

[@tonythuta7170]

Nice video

[@tkmusa5211]

Great Video. Thx for the tips. I'll be using method #2. Shop wanted 300$ to do the valve seals. So i may owe you 250

[@joyj6749]

Thankkquu bro thankkquu..💗💗💖💖💖💕💕❤

[@josepeixoto3384]

on mine, a 125 jonway,2010, the valve springs have progressive pitch coils,they are not to be installed upside down, the coils are closer together on one end, looking now thru youtube to see how they go

[@49ccscoot]

In general, the closer coils go toward the bottom with valve springs.

[@josepeixoto3384]

@@49ccscoot Yes, they must, that is why they were wound like that in the first place; it has to do with their resonant frequencies and with valve,cam lobe and spring wear,and horsepower loss; lots to read about that, i just checked w/Dr Goog, lol And since i'm here, thanks again for your great videos.

[@TN_HondaDad]

How are the valves keys actually holding the springs in? I can't wrap my head around it?

[@49ccscoot]

Look up some pics of keepers and the ends of valves. You'll see that the valves have a groove and the keepers inside are designed to interact with that. The outsides are made at a taper.

[@boxer123567]

Should my springs be able to be compressed by hand on my 250cc dirtbike ? They seam VERY tight on intake and exhaust side , please let me know if there maybe to tight or needing to be replaced ?? Thanks!!!!!!

[@49ccscoot]

Probably not. Compressing valve springs by hand is generally only applicable on very small engines.

[@anglegrinder4630]

Is that keeper placement only for this engine?

[@49ccscoot]

That's how most keepers work.

[@halrt1]

Will this tool work for a riding mower valve spring?

[@49ccscoot]

TBH I'm not sure. If it won't, there's probably another out there that will.

[@lancejonesmusic]

Hey I have a question for you since you are very crafty with scooter work. If I buy a new cylinder head and new valves, do I need to cut the valve seats or lap them? The scooter I have is discontinued and they have no more fully assembled head left but they have a new bare head and new valves. It is a 2016 SYM HD200 EVO, 4 valve cylinder head. I would assume the valve seats and valves are machined by the manufaturer to have a perfect seal if they are new. Thanks!

[@49ccscoot]

It would depend on exactly what you buy, but you shouldn't usually have to cut the seats. I'd lap them.

[@lancejonesmusic]

It is an OEM from dealer cylinder jrad and OEM valves for my 2016 SYM HD 200i EVO.. ​@49ccscoot

[@49ccscoot]

@@lancejonesmusic Should be ready to go as long as it's not a true bare casting. I'd still lap them, but it's not a must.

[@lancejonesmusic]

@49ccscoot ok sounds good thanks!

[@lancejonesmusic]

@@49ccscoot I forgot to ask. What lapping compound do you recommend?

[@H-M-78]

Does this tool work on "shim under bucket" style valves?

[@49ccscoot]

Once the bucket and shim are removed, it should.

[@H-M-78]

@@49ccscoot just ordered one from china. Will try it on a Busa head I got on the bench. But the original idea was to try it with engine in the frame and compressed air to the sparkplug hole to hold the valves

[@low9164]

Is it always better to put washer under the valve spring? Or just shave my retainer to prevent valve seal kiss?

[@49ccscoot]

If you start adding shims, it changes spring pressure and then you could also push to coil bind. In some popular applications, you can get offset keepers so you could put say a 0.030" shim under the spring and then use 0.030" offset keepers. If you're working on a scooter, that's not likely to be an option. A lot of people take them to a machine shop and get the guides machined for clearance.

[@low9164]

@@49ccscoot thank you im working on my 130cc bike

[@low9164]

Last question lol when i bring my piston to machine shop for valve pocket, can i just tell them that i use 6.8mm camshaft or do i have to bring the camshaft?

[@49ccscoot]

@@low9164 I would call the machine shop and ask them what they want to be sure. If you know all specs of diameter, position, depth, angle then they can do it with just the piston for sure but otherwise it's best to ask what they want. I know that with some of the GY6 and 139QMBs, the reliefs don't always match up exactly where they need to be.

[@smileyrod11]

wear can i get this tool let me know thank

[@49ccscoot]

I found it on eBay. Search for "GY6 valve tool".

[@samk1584]

This is clever. I wonder if a guy couldn't just use pvc and a plastic weighted hammer. A lawn mower is likely not going to break it. Otherwise, I have enough pipe. Pretty neat.

[@BombsAwayMineCraft]

I need one

What is the name and the make of the tool you used.
