CR 80 Top end rebuild (THE ENGINE IS DONE!)

[@nicholasshue1630]

How much side to side play is normal for the rod/crank

[@annihilator153]

Not side to side up and down its what you worry way more about.

[@sherwyntamag9157]

How are u sir..?I have a problem to my cr80 because the oil and water is mix what is the best solution sir

[@2strokemxclassics]

[@2strokemxclassics]

USA if its an engine casing u need

[@sasuketime7307]

Sir, can we put a 85cc cylinder on a 80 low engine?

[@northernmx5973]

I'm not 100% sure but my guess would be no. The piston and crank throw is probably different

[@oddbjrnthomassen9501]

I have a cr80r with cr85r piston and sylinder

[@Six_ftdeep32]

Why did you torque down the studs? Did it recommend that because I was always under the impression torquing down studs then the nut on top of that could Crack the case its going in.

[@northernmx5973]

Hey good question, I actually opted to tighten them down by feel because I started to torque them to spec but that didn’t feel right because it seemed too tight and I ended up not filming it.

Is it just 1 top gasket or 2?

[@northernmx5973]

Just one

Could you Link the honer that you used? Also thank you for this video it was very informational and helpful.

[@northernmx5973]

Thanks but actually borrowed that honer but I would say your local auto parts store would have one.

does anyone know if we will fit the cylinder from cr 85 to cr 80

[@jamesriceps2]

Love the content, did you put stock piston size in or did you go up any? An if so what sizes?

[@northernmx5973]

I just used a stock sized ProX piston and rings Thanks for the comment

[@jagitmax]

he didnt bother to measure

[@HarutoBoroto]

It this available

[@joebarter3722]

Pretty sure you aren’t supposed to hone a chrome bore….

[@mrbozaboza]

nice fuck up on the honing LOL. Never hone with the hard stone the nikasil cylinder

[@northernmx5973]

If the compression was compromised by it I’d agree but unless the coating is already damaged a quick deglazing doesn’t hurt anything 😎

[@rocknrye9273]

25lbs? Lmao bruh 😂💀. And you should be going back and forth cross pattern little by little until you reach your TQ spec, not fully torque 1 at a time.
