Excellent video. Thank you for sharing! I would love to see more Harley/Sportster videos in your style. They are informative, but short and to the point.
Great Video. You can also take the keepers out using a magnetic pickup tool to lift them out. Also beware of buying Harley valve stem seals because the stock could be up to 30 years old. I made that mistake when I damaged one of my aftermarket seals and replaced it with OEM seal. Then had to strip down the rear cylinder head after blowing lots of smoke after a rebore to find the OEM part failed because of lack of pliability. Its not worth the risk, those OEM seals date back to 1984.
So you just replace the valve seal by pushing it down with two fingers? Isn't it going to pop up when you start the engine? My valve seals from eBay came with a puncher tool, is that just unnecessary to use? By the way great video.
When reinstalling the valve back in just coating the steam with a little motor oil is enough to lubricate ? The Manuel calls for all these different compounds but if just putting a little motor oil is enough I’d rather just do that
Hi my 2006 XL1200R might also suffer from the TSB leaking valve seals, do I need to remove the entire head to change the seal? Can i leave the head on the bike and remove the valve seal with the valve still in place? Also, can the old magnet in a socket trick be used to smash a rubber mallet down over the springs and collect the collar/keepers if i dont have a nice compression tool like yours?
What were the symptoms. I have a 1998 80 cubic inch evo. It's jetted for 2 into 1 exhaust and we put it on a bike with true dual exhaust. I smoke on full throttle. Cant figure out where I am burning oil. It runs so good. Is there something I can run through it to try and clean the engine first before tearing into it?
Would a symptom of a bad valve guid seal on a 92 Evo 1200, be excessive oil blowing through the breather bolts and saturating the entire air box/filter? Currently at the halfway mark on my dipstick (from full) after riding 400 miles. Filter is wet and oil has been dripping out of the box onto my exhaust. Overall bike runs and sounds excellent.
Hi. I had a set of james valve seals. And when I push them on all the way down, they spread stem hole. So I had to pick up them a little. Now my bike is fully assembled and I'm thinking about if they will popp off some day... Should I be concerned about this?
A broken valve spring could release the valve hitting the piston causing a hole in the piston . The pressure from the spring holds the valve keepers to the valve . no pressure on the keepers from the spring can would cause the vale to fall onto the piston.
A bit late but look inside your intake after removing the manifold. Lots of gunk on the valve stem is your indicator. It's a bit harder to tell on exhaust side.
you can also compress your valve springs using C-clamps just fyi if you dont have money for a vsc also if you wanna do it really quickly, get a socket and a rubber mallet, put the socket over the spring have someone hold the head down and cayrefully hit the socket with the mallet until you hit it hard enough and the keepers will pop off as the spring compresses down far enough, you'll still a vsc or clamps to put the springs back though.
@@hakuinz4226 yeah, ended up using a socket and hitting it with a mallet. the valve spring ended up breaking my compression tool. still not sure what i was doing wrong there haha
You have the valve out why you did not receipt the valve you did not do a valve leak check why did Justin do a valve job by polishing it wouldn't hurt I would have done intake and exhaust valve at the same time very disappointed

very nice video, I did just that, install the seal a 1/4" from top per James instructions without tools just a little oil, thank you

Great video as always.
Ruskie Thank you for watching!
Can this same technique be applied to a 1980 shovelhead as well?

You only need one person with the proper valve spring compression tool. They're relatively cheap at Harbor Freight.

I have a 98 evo with the exact same issue. Currently doing a top end rebuild. Just got the pistons back in. I am pretty much replacing everything. lol
I wonder if i can use some compressed air and my hose from my compression checker and do this with the head still on my bike.
Actually I'd take the head off so u can clean the valve seat
Interesting , I've never seen a Valve Spring Compressor like that . Mine is like a big G Clamp .
Autozone
Nice vid mate
Thank you sir!
It's not unlikely the guides are worn as well

well, james installation instructions, that i found to this seals, tells its ok.
@@BigBlackTruckDave hi, I sold the bike
How would you know if you have a broke spring, What to look for and how would the engine sound running
A broken valve spring could release the valve hitting the piston causing a hole in the piston .
The pressure from the spring holds the valve keepers to the valve . no pressure on the keepers from the spring can would cause the vale to fall onto the piston.
how would one know their valves are bad . does it show with fouled plugs ?
A bit late but look inside your intake after removing the manifold. Lots of gunk on the valve stem is your indicator. It's a bit harder to tell on exhaust side.
omg guys, use a magnet to get the keepers out

doing exactly what is being done in the video, but the spring wont budge, not sure what im doing wrong here.
Did u get it?
@@hakuinz4226 yeah, ended up using a socket and hitting it with a mallet. the valve spring ended up breaking my compression tool. still not sure what i was doing wrong there haha
What is the name of the tool the grips the springs ?
Valve spring compressor
Is anyone else thinking that new seal is too tall, and as soon as the valve comes down it's gonna destroy the seal?
I didnt use tape on my Install, hopefully I'm alright
You have the valve out why you did not receipt the valve you did not do a valve leak check why did Justin do a valve job by polishing it wouldn't hurt I would have done intake and exhaust valve at the same time very disappointed
