engine piston check
-
Bit of piston ‘scoosh’ is to expected in that condition
The crank turned real smoothly as well? No little stops or notchyness?
Bud! What are the first 3 numerics after the * on your engine and frame? If you let us know we can find out what year and model you have. It’s especially important when it comes to electrics…

@SpookDog yo one last thing i made a video today of kicking the bike over just so you can hear the bike make that friction noise to know if the crank is good, idk maybe just my stress is making me hear it or idk here is the vid https://imgur.com/gallery/HRIy3mb

@MadGyver yeah it has low compression its easy to kick and had blow by when i opened it, the bike is waiting for a rebuid i just got a top end athena gasket today i will get a piston in 2-3 weeks and i will send the barrel for a rebore to 57mm im just trying to check if the crank bearings are in good condition as my bike drank coolant before and i was thinking it could of caused corrosion in the bearings and that could sent my whole engine to the moon

@SpookDog i will make a vid when i open it up, but all im saying is if that noise is normal i think it comes from crank rotating and the pistons it should be normal as things move there and make friction. anyways i will make a video when i open it up again and send a video and we can discuss a bit more acurately

@erion1 After you remove the top end,only an experienced one can tell you if it's ok the bottom end at a 90%.
To be sure 100% you have to dismantle the engine.
When rebuilding,changed conrod just in case,because 0f 56k km's of the engine.bearings still had life and the con-rod was so good that a friend with a machinery shop checked for tolerances and told me to keep it for backup with a new set of bearings.
I just couldn't gamble with a top end rebuild of an unknown internals condition.Piston condition was way better than yours,still have it.
You get me what I mean. No video/sound recording can replace that. -
@MadGyver yeah i get what you mean, im not woired that much about the crank i just know that it used to loose my coolant and i know that i drove it everyday and i dont think water could of stayed in the engine to cause corrosion, based on my thinking(haha) i just imagine that the water evaporated from the crank everytime i ran the bike
