engine piston check
-
@SpookDog it was good when i got it at firs as long as i remember, as for the rebore i got a oversize piston first then sent them together for him to make them fit and the oversize was enough to remove all the scratches, i think that it is movin a slight bit bc of the worn out rings and that it made contact with the cylinder only on those 2 sides and the rings weared ore on those 2 sides and not it taps, hope you understand what i mean

hey @SpookDog i was wondering if what happened could cause my crank bearing go bad as someone told me that, is there any way i can check that, i was thinkit that the water that got in caused corrosion on the bearing or something, i just don't want my engine to go boom haha

What are the first 5 letters and numbers stamped into your frame (headstock) and engine block? (above clutch arm) …
The crank would rumble when you spin it, and feel ‘notchy’ if it was corroded or damaged.
Also with ‘normal’ wear the stator could be moved, it’d click slightly when gently shimmied with a flathead screwdriver. Or even by hand depending on how bad it is…
I’d be more worried about you crank if it’s as bad as you say!… -
@SpookDog i checked for play when i had it apart it was perfect no up down play slight side to side which is normal and as the bike drank my water before i was thinking it could have litle bit of water in the crank so yesterday i put some 2t oil on the tank for more lubrication on the crank and let it run for a bit so it gets lubed up and maybe prevent corrosion if it didn't happen already

You still have the barrel off yeah?
You should be able to rotate the stator easily by hand. It shouldn’t make any rumble noises or feel clicky/notchy when you turn it…If you gently lever the stator up and down it shouldn’t have any free movement. It might flex a bit if levered too much…

@SpookDog no i put everything together as i needed space in my garage and had no place to put the parts and im not runing the bike either so its gona be like that for a month as i don't got the money for the new stuf rn but i'll take it apart again to check that then, but that what you told me is to check the crank bearings right? not the rod bearing it could be good if i can check both of them if they are in good condition without spliting the cases
Thanks for the info! -
@SpookDog i did what you said but i didn't take the cylinder off i only took the sparkplug and took the stator side cover off,
it could be easily turned by hand and it has no movement up or down neither side to side no clicking no nothing just a little friction noisse wich i think is coming from the piston as its not in a good condition -
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
