This video explains how the KIPS powervalve works on a 2001 KX250 model. Others are similar.
Great simple explanation of how the KIPS works. I had a KR1S and although I knew what it did, I didn't know the mechanics behind it all. Thanks for the info.
I had kips power valve on my 1990 blue kmx and it worked perfectly
Nice job, thank you. As a moto guy I never liked how the Kawi’s turned, so I had everything but. Now I’m old, I can still ride I’m in shape but realized since I no longer live on the east coast,( Kodiak Alaska ) I need a much different bike. It’s mountainous here, needing a much lower seat height compared to motocross I remembered and found a prestige 94 KDX200. Thanks for the insight
Yup, we rode those bikes from the 70's because they were new back then......and so was i. These years im still riding them
.......but it hurts so much more when you wipe out. :)
Kips power walve is the best ever❤
Gr8 video! I owned a 1990 KDX200 and never understood how the Power Valves worked. Thx.
No problem! Thanks for the compliment!
any guy taking his time to talk about kips is "RIGHT ON"! old technology.. but hey IM old! whOO hOO
Thanks for the informative video! Greetings from Finland.

Man I couldn’t watch the last part properly, I kept head bobbing to tunes 👌🤘👌🤘
Wow........what great informative videos....I need to get my son on these too so he can look after his new to him KX125........Will drop you a beer for sure....
Hi i use Kawasaki Ninja RR 150 2 stroke and it has KIPS too
Great video helped me out alot now I can understand what a power valve does
great Video! I had to learn this the hard way
That sucks. I was going to run mine a bit longer, good thing I didn't. It needed a rebuild for sure.
You broke your bike?? Shyet
What ever happened to 2 stroke art?! Awesome video on the kips system best I’ve seen buddy 🤘🏻👍🏻
This is fascinating to watch but I sent the bike away to have it done. This would have taken me years.
Rc vintage channel he found some of his power valve in the exhaust pipe
If the KIPS is stuck or not timed right will it cause a low compression (wont start) situation
If its stuck open then it will have lower compression but if its stuck closed then more compression
i picked up an 03 kdx 200. its all stock. i had a power issue and thought it was a bit rich. i went to a 45 pilot and 155 main. it seems healthier has surprising low down grunt. however i dont seem to have much of a powerband. first time ive ridden a kdx200 but i feel like it should be making more power. my wifes kx100 would eat this thing for breakfast. do they just naturally have very smoothe power with not much on top? or could i possibly have a kips valve issue? bike runs really smoothe its a low hour bike for sure it hasnt seen much riding.
very professional
my kx 80's kips valve is off alignment. do i just remove the shaft and align the shaft with the markers? also it has a wobble at max rpm, is this the shaft or it just running a bit lean?
Fix the powervalve first. I'm not familiar with the PV on the 80's, sorry.
❤
Does the latest Yamaha Yz250 do these 2 things simultaneously as well ?? I ask being the yz has a very broad powerband.
I have a 1995 kdx 200 and the ticking from the power valve is very faint on mine, is that bad? Some say it it because it can be gunked up and cause power loss.
When do you hear this "tick"?
Tick, rattle, noise, whatever you call if. I only hear it when it revs up high and slowly revs down, but its very faint
Anyway you can post a video? Pull the linkage cover and see if noise follows the movement.
Is that on the side or the front by the exhaust port?
RH side
I bought a 03 KX250 but it has a 02 engine. Can I put a 03 head on a 02 engine. The engine mount is on opposite sides of the head from 02 to 03.
I can’t find a governor rod for a 1990 kdx200
Hey Matt, I’ve got a ‘92 KX250 and the KIPS, once activated, doesn’t deactivate. I took the right side cover off and could move the arm freely with no spring tension. Is this normal? Or did a spring break somewhere? Thanks so much for these videos!
With linkage disconnected, the govenor should spring back. The PV in cylinder should move freely.
@@HTMR Ok good to know.
I just bought my first bike it’s a KX125 and I had to tear the motor apart to replace the input shaft bearing, anyway my kips system doesn’t have the exhaust ports only the mechanism that lowers the port height. Can’t find anything on it wondering if this is a problem or the wrong head or something
125 is a bit different, what year?
I am rebuilding my dirtbike rn and I am missing the small dark metal cover just to the right of the valve cover what is that called and what year is this engine
Mine is an 01'.
MatthewMCRepair do you know what tht cover is called or the part number
@@chiahang839 Have you tried looking it up in an OEM parts finder?
How do you get your engine so sparkly clean? Wow
Cylinder was sent out for replate, so they bead blast it. I soda blasted the rest of the components.
Also that cross hatching looked great in your cylinder. Did you do that yourself? What year bike?
@@braroute3202 Scroll down and see before and after : www.howtomotorcyclerepair.com/kxenginerebuild/
u have a fly wheel weight, what size do u thinks the best for woods and hill climbing
To install the gasket of the Exhaust Valve cover, do you have to remove the engine from the frame or not?
I don't know
My pv isn’t working right on my kx100 I did a top end and now the band don’t kick In idk what’s wrong
What is the different of KIPS and SuperKips in zx 150 rr?
sir, what is that hi pitch ticking only some kdx bike have? Im not speaking of noral engine sound "i've heard both before and some is way worse
Question what all year power valve setups fit the 1989 and up
My sub port valves are stripped in my 2001 KX250. The model number is 12005-1304. This part is no longer offered from kawi. Will other model valves work? Thanks for any info.
This has been discussed many times over on the KX250 facebook group and the thumpertalk kx250 forum. Try asking your question there.
Curious about the open position, when timed according to manual and valves opened all the way there is a small gap where I can see through the valves into the chamber. At 4:53. Is that gap normal? I would assume that there should be more of an opening there. Any info is appreciated TIA.
Well, move it over a tooth and see if it improves. It probably won't.
Yup he’s got this wrong according to the manuel
I have a 99 kx 250 that I just pulled the power valve assembly out of and the rack rod that rotates the sub port valves has notches on it to indicate what tooth on the sub port valve goes there. Only problem is that the manual shows that there is a notch on the rack rod that is not on mine and was wondering if you could shed some light on that I'm willing to email pictures to you if you could help. Thanks - cody.
Yes, send some pics: www.howtomotorcyclerepair.com/contact/
Werw can I get my power valves for my 1988 KX 125 with out them I cant ride
Did you try to see if available OEM?
Hey great vid! Can u please tell me where I could purchase the kips assembly for a 94 kx 250? Not having any luck myself...
There on eBay not cheap mind 🙈
Matthew i have a question if you ride on woods only you have to do something on kips powervalve or theres nothing to do
Not aware of any PV mods. Maybe consider porting to suit your riding.
Hey Matt, I have a 2003 Kx125, the power valve shaft seems to be jammed or stuck,
Any suggestions to get it out?
Have removed set screw and pin.
Cheers

Can you link the 2 hour video

I've just rebuilt my 07 kx125 it seemed a lot different to the 250 you showed here??
Yes, some models have some differences.
I did a top end swap, I used a 2005 kx85 bottom end and a 1991 kx80 top end and swapped pistons, it turns on with starter fluid and only runs when I’m pulling the throttle. I don’t know if it’s the Carburetor or missing power valve from top end. I’ve tried tuning the carb but it doesn’t change the situation... any suggestions??
You have a mixed bag of parts, did you verify that they are compatible?
MatthewMCRepair yes they worked perfectly
Make sure carb is clean, especially pilot jet.
i put my bike back together afteri cleaned the power valves and now the power valves only open sometimes, could it be the power valve actuator spring? would replacing it fix it?
Was the PV easy to open/close before sliding the cylinder back on? If so, I'd look at the governor. You are revving it up pretty high right?
MatthewMCRepair yes it was very smooth before I put it on, yes I would rev it high and it wouldn't open so it sounded awful lol, but every few times I would rev it.it would open and work and then it would just stop opening. do I need the whole governer? or just the spring?
Can you still find parts for these easily? Thinking about getting one
Depends on year. There is a guy on FB that is manufacturing the powervalve parts for ones that are obsolete.
Can I do this while motors in bike I re ringed the piston now I can't move the power valve on the outside to hook it up wtf????????
No.
Do you think the bike can make as much power with no valve made into it ?
No. The valves purpose is increase low end power and keep top the same. It also smooths out the transition between low and high.
+MatthewMCRepair is it the same as krr 150 power valve?
My 2004 kx100 falls flat on its face when the powerband should be hitting... Any suggestions?
Give me more info. New problem? Any modifications?
Just bought the bike. Rode great for 3 or 4 rides. Each one a few hours at a time. It started to bog a little. Thought it needed jets cleaned. It stayed running and would only bog every now and then.
The next time we tried to start it, it wouldnt start. I bought a new carb installed it got it started. Did the carb adjustments. Revs perfectly. Revs high and crisp. Went to ride it and every time it would want powerband power it bogs out. Read into the kips governor shaft. Thinkin it could be that
@@kevmc209 Can you post a video?
I think i found the issue. The power valve flaps were so dirty with carbon they were stuck. Had to use pb blaster to get them out. Cleaned the ports and replaced the flaps. Putting it all back together today with new piston, rings, carb, clutch, and gaskets..... If the problem persists i will post a vid. I already had the bike torn apart when you asked to see
I have a 98 kx 125 and when I rev the bike up the linkage doesn't move up to move the power valve? Any idea on what might cause this
You inspecting for movement where? Under the small cover?
@@HTMR yes Unger the cover I found that the linkage moves but the bike hits the power band late and revs way up
Wait, you said it does not move, then your next comment states it moves? Disconnect the linkage and see if the govenor moves the arm. Try and move the PV rod with your hand.
@@HTMR yes I can move it it is stiff but does move the bike won't hit the power band it just revs up like it wants to shift to early
If it is stiff, then it it top end time. Does the govenor rod move when disconnected? Does it move when you rev it up?
Why doesnt the piston slam against the valve from below?
The powervalve never should protrude into the cylinder.
MatthewMCRepair but if it doesnt, how can it properly seal in closed position?
It's not an air tight seal. It simply diverts most exhaust gasses.
MatthewMCRepair I have a 1999 kx250 I have some ware markets on my cylinder head can it be be clean up some one told me it's Nickla and can't
The cylinder and/or head can be repaired. Send it out to millennium inc.
94 kdx200 what the ticking they make when bad>?
Huh???
FYI you sound very unsure of yourself when it comes explaining whether the drum valves and port height relate to low rpm grunt and power or high end power. I'll look elsewhere to make sure.
When the flapper is down and drum valves divert exhaust to side chambers, that is for low RPM.
