It won't hold up to the heat. I've JB welded body panels together, and the grinder made enough heat to melt the weld.

good up to 500 degF

avg. ATV cyl. temp on fairly hot day 230-240 degF

If it will hold up to the pressure the I don't see why not.

In my experience, JB weldi s terrible on radiator applications or other liquid applications because the liquids eat through it and soften it up. Plus it's hard to properly prep an area that has liqud going through it so that gets half assed most of the time.

Where in the ---- did you get that info from? ::) The average cylinder temperature on an "ATV" is 230-240? Are you talking about the outside of the cylinder as in the part that's exposed to air(that won't raise compression, dipshit)? ::) There is no ------- way the inside of the cylinder is "on average" 230-240 degrees. I've seen plenty of exhaust systems glowing red hot so there is no fuckign way the combustion chamber is that cold. :1 Punch yourself in the nuts.

No you haven't. ::)

No it's not. :3 Even a highly modified 200cc 4 stroke is slow. :l

So much so that reading this post has made my head hurt

I started to make an actual reply, but then was like WTF. It isn't even worth it. The whole idea is idiotic at best.

Re: Raising compression using Jb Weld?

there really is only one true way to find out yourself.

Re: Raising compression using Jb Weld?

if metal pits in combustion chambers how would jb weld survive

Re: Raising compression using Jb Weld?

personally i prefer piling up the Weld on my piston with a mig. I made a 25:1 compression piston once....................... :6
