I am trying to understand how this happened so I don't repeat it with a new piston. Was this likely caused by improper installation of the wrist pin clips by previous owner? Or because I ran it too lean and it got too hot?
This tragedy has got me considering a kit. It will be my first kit on any bike except one (already had it when i bought it). I have read loads of posts and wiki articles about it but there are still a few things I was wondering about.
I see lots of posts of people complaining about shitty clips in kits and saying not to use old ones. But I don't see any recommendations or links for "good clips".
I am considering the
Malossi cast iron 70cc https://www.treatland.tv/hobbit-malossi-cast-iron-70cc-kit-p/honda-malossi-45.5mm-313642.htm
Any others I should consider for the NU50?
Can I use my stock head on these kits (above) or is that a bad idea.
I think I read that the jet on the stock carb is 85. I see people posting good results with DR kits and 90-95 jet in stock carb. I was planning on just getting a 90 and 92, should I get more jets in a larger range to find the right one?
