Hey guys, im new to the forum. Recently just bought my blaster back i sold in 2005. 11 years of sitting i changed oil gas and all the good stuff. Started right up but after rising for a half hour it overheated and shut off. Got it towed jump started it on the way and it ran till about a minute from my house and it started knocking. Read forums on here saying piston slap. So i took off the head and cylinder and sure enough the piston was done. Everything has no issues. Sleeve is clean and scratch free as well as crank has no play. Drained oil and no signs of metal.... Now to my question, i assume i jusy buy a replacement piston that vitos sells or so any of you guys have suggestions on what piston to buy as far as a brand and what size i would need for my vitoz 240bb kit i have on now. Please with all regards i would love any feedback. Will post pictures here shortly. Thank you
