ok so ive had a post about all the problems i was having with the piston scraping the cylinder with my new bbk possibly because the studs wouldnt torque all the way down, well i put it together again with new studs and i stripped them on atleast one inside the case where the cylinder studs go on the cvt side. (not the stator side) so...fml right? always the worst luck, what do i do now??? can someone please help me, ive spend enough money on parts trying to fix this bs problem i couldve bought a junk scooter and had a whole engine to use for spare parts! i really cant afford to spend anymore money that i dont have and this is my only transportation to and from work for me so support my daughter and myself and keep food on my table. any help will be appreciated. i know im going to need new studs and nuts but i dont know if i can re tap the hole or what, when i was torquing them down they were all good and actually got to where they needed to be and i was on the last one and i heard a loud snap and i assumed the stud broke but after dissasembly the stud was still together and the threads were stripped inside the case, but the snap sounded like something definately broke but i didnt see anything in the hole except the stripped threads, is there something broke inside the case that im not seeing and just wasting my time even thinking about fixing these threads??

i torqued to 19 ft lb. and none of the threads were stripped inside or out of case, studs, or nuts. there was just one stud that doesnt get the pressure required to click my torqe wrench, i think its just stretching the stud to the point where its about to break so i ordered more. but im more worried about why the damage is being done to my jug and piston and whats causing it, do you think its the one stud not being tight enough? it still gets tight, probly about 15 ft lbs but not where it should be

I have a 50cc with a 50 mm airsal kit, i just had to order a new kit and rebuild because my engine started knocking so i took it apart and the piston lip was bent upward on the very top lip of the piston on both sides opposite of the wrist pin axis. i assumed the wrist pin froze up and that caused my problem but i completely rebuilt the engine and checked the crank, it was ok so i put back together with the new kit and took it apart after running for a few minutes and the piston and cylinder were both scraped...what is going on! here are pics

i think my cylinder is still good tho surprisingly...i went ahead and paid 120 buckaroos that i dont freakin have for a new airsal kit anyway tho. i will post pic of the cylinder if youd like, it has a few visible marks but nothing you can feel, i think it could be honed out. anyway, back to my question of why did the pin freeze, and how to prevent that from wasting another piston? also how to remove the excess piston from my damn engine?
