Raising compression using Jb Weld?
Alright so I've seen Jb weld used to fix holes in pistons before, I've also seen it used to fill gaps in the cylinder wall. Than I began to think what if you used Jb weld to create a dome on the piston only about a mm or so high. Could this be done if the jb weld was made sure to be uniform all around and still have the valve seats in the piston? Just wondering because I have an Atv and the compression ratio is only 7.6:1 and well I'd like to have it a little higher.

200 cc honda 4-stroke.... It's surprisingly quick as it stands but as with everything you always want more. I have a few spare engines so if this seems feasible I may try it out on one of them and hopefully I will get a deacent amount of time on it.
If it doesnt seem feasible I may still do it anyways lol get 15 minutes of fun....

no way this would work. The jb weld will melt right off. I tried to use jb weld on my friend oil feedline on his turbo once and that ---- melted off into a bubbly mess of liquid in about 5 minutes lol.
