Kawasaki 650 X2 Engine Disassemble & Rebuild

[@FrankRommerts-dr4yp]

Oh man, I can see so much potential in these engines, a set of nicely ported barrels with high compression heads, full circle crankshaft, PVL inner rotor ignition, Dual Mikuni SBN 44’s, V-force 4 reed valves, dual expansion chambers without water jacket, carbon silencers without waterbox….

You want all the POWAH and SOUND 😂

@@CoyoteChris You can’t go wrong when the amount of horsepower you produce equals the Decibel levels you produce…😂😂😂

Ohhh, Teaser at the end! Nice! She's a beaut, Chris!

[@CoyoteChris]

😂 I always wonder who can make it to the end of the video, every once in a while, I’ll leave a little teaser. Those are before the graphics, I got a few more videos to go.

[@StefanMailey]

@@CoyoteChris I enjoy your vids, buddy. Im slowly getting my X2 finished up. So I get excited when you post content. It keeps me motivated!

[@CoyoteChris]

@@StefanMailey Thank you, I wish I could post more often but it’s a little time consuming especially with kids. 🤘🏼🔥

[@EricWilliams-q1v]

Do you remember what the compression with the first head was. I have a used MARINER head I was going to try.

[@CoyoteChris]

@@EricWilliams-q1v with the ocean pro head I believe it was around 210psi, the stock head is around 155psi.

[@FastFlash-dg2fc]

Is okay to use a metal brush on the drill to clean up the engine, like where the gaskets are? I noticed when I did it, it left surface scratches

[@CoyoteChris]

No, the best way is to use a razor blade up right going side to side not trying to scape. You don’t want scratched or gouges on the surface.

[@1MichaelJones]

Coming also really nicely Chris!

[@CoyoteChris]

Thanks 🤘🏼🔥

[@lakelifeandbeyond]

Great video as always!

[@CoyoteChris]

Next Sunday will be the final assembly and first water test. 🤘🏼🔥

[@airsoftknives1234]

How did reusing your head gasket hold up ?

[@CoyoteChris]

I used a new one when I put the last head on. I did the compression test with a used gasket.

[@jackmessel1136]

how much did the compression change after you put the new head gasket on it?

[@CoyoteChris]

Honestly I never put a new gasket on it, seemed too high for what I was building.

[@FastFlash-dg2fc]

Which Piston Ring brand do you like to use?

[@CoyoteChris]

I prefer WSM 👍🏼

[@FastFlash-dg2fc]

@@CoyoteChris my 93 x2 is stock, so I’d buy the 76mm ones? I’m guessing the 1mm over and other ones is because someone honed out their cylinders, and now they need a bigger ring?

[@FastFlash-dg2fc]

@@CoyoteChris any advice on putting them on? can be flipped either way? And just have them lined up around the little lock for both of them, and squeeze? Bought the “Namura” rings and ruined them. I didn’t think they were good quality, so maybe that’s why. Idk. Probly user error lol

I'm still in the middle of rebuilding my 650. Waiting on my crank 😢😢😢

[@jamesgustin4195]

Good to know about that spacer too thanks.

[@CoyoteChris]

@@jamesgustin4195 Yeah it would have sucked if I had sent it back without catching the one piece. 😂 Sometimes luck is on my side. 🤘🏼🔥

[@jamesgustin4195]

@@CoyoteChris I also hit and ruined my stator. Good times. Live and learn.

[@CoyoteChris]

@@jamesgustin4195 yeah well as you saw I broke the coupler like an idiot. 🤦‍♂️

[@FastFlash-dg2fc]

Is there anything cheaper than the 1211 engine gasket silicone?

[@CoyoteChris]

I’ll be honest, I’d be afraid to try anything different I know 1211 is amazing and it works every time.

[@FastFlash-dg2fc]

@@CoyoteChris okay 1211 it is! Thankyou for the quick responses. My motor currently has 150 compression in the rear and 141 in the front, I’m currently at the part where I need to spray some blaster to get the motor apart to check the rings to the pistons. I’m guessing the front piston rings are messed up which is giving me 141 in the front. The head gasket looked fine, so does the top of the piston. Anything else you can think of if it’s not the rings on that front one

[@CoyoteChris]

@@FastFlash-dg2fc yeah it’s probably the rings it may have ran lean on that front cylinder. If you didn’t wanna do a full piston bore then get the cylinders honed and new rings. That is if everything looks good. No scoring or bad spots in the cylinders.

[@FastFlash-dg2fc]

@@CoyoteChris so taking a look at my rings on the front piston it looked great, the cylinder looked great as well. I did notice the front crank shaft was darker than the rear one, but as I was moving them I didn’t hear a difference in the nose of either. I’m guessing it was just the gasket and then the head gasket.

[@CoyoteChris]

@@FastFlash-dg2fc more than likely the rings are worn. 🤘🏼 I’m assuming you are changing all the gaskets including the crank seal.
