Hot rod bottom end kit experiences?
Has anyone had any experience with hot rod bottom end kits? My 125 shat itself today...
also, I'm running 50:1 mixture, piston and rings have no scoring at all, no signs of detonation etc... what could've caused the big end to fail?
Cheers

Ideal cheers  you can see where the bearings got hot and failed... 50:1 is what they recommend running it on, plug colours good, if anything a bit black. No signs of any dirt or shit in there. Would it be possible as the bikes been sat untouched in a shed s few years there was some rust on the bearing and this has caused it to shit out?
Nope Honda

50:1 is an EU directive, not the manufacturers recommendation

32:1...25:1..obviously the more oil you run, the better the piston ring seal.

50:1 is less oil in the mix than 32:1 etc.
50:1 is 20ml of oil per 1l of fuel.
32:1 is 31 (and a bit)ml to 1l of fuel.
