Shows how to install piston rings and the piston to the connecting rod in an engine, which can be a small (e.g. Predator 212cc, Briggs) or any automotive engine. Installing piston rings and a piston into the bore is part of a build playlist to add performance mods to a mini bike engine. Installing piston rings and a performance piston will allow you to have less horsepower robbing drag, and let you reliably rev to very high rpms. A performance piston is only one part of the puzzle, and should be used in conjunciton with other performance parts for maximum performance and safety.

Wow. Smooth presentation (no ums,ers,ahs), lots of light so you can see what's going on, subject covered effectively.I have used some other youtube videos for car maintenance and repairs but this is my first foray into rings/pistons and stuff like that. I think I got lucky and found a good source right off the bat. Will look for your other videos, thanks!
what is I very love this men.is so easy to understand what him doing....very nice the voice is clear....I like u...keep up .......A+A,+
Awesome job ! Very informative and broken down with perfect directions. also, the lighting thumbs up!!
Thank You for the great video and information. Good of You to share. Again Thank You.
Finally you covered the problem that I had, which was the ring gap and the degrees apart. I needed to actually see it. Of course I’m a 14 year old boy building a stage 2 predator on my own sooo.
I’m gonna build a Briggs flathead and I’m 12 so home urs goes well
I know a decent amount about small engines tho
I’m 8 and I built a car engine
this video helps alot. thanks, keep up the good work
Thanks! I needed to know how to do this for a while
no problem
Well done video
Great stuff thanks for the video!
+Cr125stin no prob
This is dope
good job
send you a great like from egypt
Good job
Ty Ty
Does these procedures apply to my coolster 125cc?and what is this size that I can use to adjust my valve?
Excllent video
Sir model no-d4dh4-2500awm compresor.i want install but both the piston rings same how to install?
Awesome thank you
No problem!
nice job
thanks
Thanks for this video, also, I didn't know how to do the piston when doing my billet rocker arm. Come OOONNNNNNNN, tax returns. ( ; ) )
If you leave the connecting rod and just pull the head off how do you compress the rings to slide the head down. Saw this done in another video maybe that’s not recommended?
Greetings! New subscriber. Thanks for a quick but informative video!! The ring pliers…there are several types, do you find any one better than another? Looking forward to viewing your other videos. Thanks again for sharing your knowledge!!
Cheap ones work
@@MR_IC if its rusted inside, reusing old rings is not a good idea.... just buy new rings, they are cheap
I replaced the piston before all by hand, I'm not sure how. I have a 38mm piston that I'm trying to get in the bore. It's for a German moped. The only piston compressor I can find is $25. That seems like a lot of money for like 1-2 uses. I'm going to try and use 1.5" tubing instead and makeshift my own compressor. I'll let you know how it goes.
Thanks BTW for showing how you do it. It's pretty straight forward and yet I didn't even think of using a tool like that.
Can you change mines on my 2003 Mercury Marauder? Please
How much does it cost to get the pistons rings installed
Bro how much price of Suzuki gixxer (pistan price )
Does all wrist pin come in same sizes regardless of what motorcycle you have?
Wrist pins come in all different sizes.
nice video, what if you put the ring gaps 180 degrees apart?
Beats me. 120 deg is what they all are installed at.
*****
is that what the manufacture specified?
yep. Rings should not be at a 90 degree to the wrist pin, or in the same position to wrist pin.
ok
Does it mater the piston orientation in the block ? Mine isn’t marked ! Some I’ve done had markings , an arrow or a line or something , this one isn’t . It’s a HSK70 Tecumseh .
Check the tecumseh factory service manual. Also check underside of piston. Some have no marks and it doesn’t matter which way.
If there is a gap between piston and cylinder wall that will cause no compression correct?
Needs gap or it seizes
mine slowly reveals gradual amounts of oil creeping up from the cylinder walls. None of the rings are broken and look fine, the cylinder wall looks perfect, it shows the original machining texture
Check ring end gap. Check to see it rings were installed upside down (esp the second ring)
@@KartFab Ok ty I will do. also maybe they have lost a little bit of strength, I will try and carefully spread them out to make them springy again :)
@@friedchicken1 if you do that, you might warp or have excessive tension on the rings. Its better to buy a cheap set of new rings than to try and add tension to the ones you have.
Do the gap ends have to be 120° apart or does it just have to be away from each other?
Do 120 for install, rings end up spinning anyway when running
Hey bro I just saw u video .. I just go 98 intruder ., blue smoke come after the bike die in a red light I started agiain I have to keep givin gas to no die ...I get home I turn off and after 20 minutes I start again is when the blue smoke come from the pipe for like 5 seconds a lot later less and less till no more later nothing I have been riding for like 2 days and no more smoke ... what u think tha happen ? Thanks ..., great great video
Blue smoke=oil
What type of oil do you use in the piston and rings?
Any oil will do with a mild build. Typically 10w30 for above freezing and 5W30 for freezing temps
How to understand piston Ring depreasation
I have an aluminum briggs 6bs from the 50s and it's losing compression because I overrevved it and wallered out the bore, is it worth fixing?
+Gslash25 hmm. You can take it to a shop and have them sleeve it, then put in a new piston and rings. Now..... Is it with it? That totally depends on you.
+KartFab ok, might've been worth it if I had left it in more original condition or made power, but I might put it on my great uncles one wheeler peeler kart
+KartFab and thank you for responding as well! it sucks to see you tubers that don't reply to comments
This looks to tough for me hopefully i can find someone to do it
its easy
Can i plz have a link or size of the ball bearings I need one for higher RPMs😭😭😭
Higher rpm’s ball bearings are the least of your concern.
@@KartFab I know but this Build has A car accelerometer and I kind of need it😭
@@KartFab I am so trying to make the fastest bridges
Where did you buy the piston and rings? Did I miss a link in the description?
+Kuiper Roerdink yep try reading it again.
The rings that came with the piston (flat top piston ) from go power sports , the waffle one seems to be huge and won’t compress. Am I doing it wrong or did they send me the wrong rings with the piston ? Ty
I dunno
@@KartFab I figured it out . This was a while ago . I was so dumb 4 months ago compared to now lol.
Where did you get that piston? There was no link in the description.
Also could you give me the part number of the old and new piston?
oops. I got the piston here. The raptor/5 hp flatheads are the same bore and stroke so standard piston was the one i got. www.out2win.com/catalog/raptorpr.html
Once I upgrade the connecting rod, piston, flywheel, camshaft, etc. will it be safe to remove the governor and put the engine through hell of a high rpm?
yup. I doubt you can get it to a super high rpm without doing a lot of modifications for flow, getting timing just right, and having a wild cam with upgraded valvetrain.
Hey, this is my brother's account but I only expect to get 6300 rpms, as that is what the fillet flywheel, connecting rod, performance piston, performance camshaft, upgrade valves and valvesprings can handle. I am trying to do this to a Predator 670cc and place on an insane off road go kart.
predator 670 has had some issues past 5500. Good luck as you are in mostly uncharted territory.
Alright thanks, I will need the luck!
Also, IIRC there isnt a huge selection in performance parts for the predator 670cc. I do know that the honda gx390 stuff would fit the honda gx620 etc, but you would have to do a lot of research to see piston size, rod length, rod end sizes etc in order to figure out what to get for the predator. If you do the math, it is actually cheaper to get a decent used motorcycle engine with insane hp for a lot less than hopping up an engine like that.
Don't just torque the ring compressor until it squeals. Tap all around it as you tighten. Novices know that.
hello Kart Fab. i got interested with your video. i would like to buy .piston with its rings for scooter VESPA EF2 50CC.
KINDLY ASSIST .
My piston does not show an arrow indicating which way the the piston should be oriented.
Might not apply then…
Rod bolts on a arc rod are 270 or 170 inch lbs??
Depends on the rod. The smaller rods are 170 inch lbs and big block stuff is more.
@@KartFab thxs sp much for the fast response I'm at my table doing it now and it's a ARC 6269 rod thxs

hi old piston rings back in the bore
👌😍👍
Wow this is difficult
So what you are saying is I can’t do this shit by hand... fml
you can rent this stuff from autozone for free, you just return it when done for refund. Its part of their "tool rental" stuff.
first bro
You did not say a fucking thing how to install rings
All them fancy tools are a joke.
but helpful
@@KartFab Yeah at disgusting disgraceful prices usually because scum are in control
& why the hell did you oil the piston when putting it in? The best way is dry
