20 over bore

the gaskets will be fine and use carb cleaner first then do dishsoap on a paper towel till no more dirt shows up on the towel. go around in circles not up and down
when my build was done i saw the gasket kit was marked 68mm, and its been fine. i dont think ive seen other sizes for a blaster now that i think of it
it has to be the biggest opening, if it was stock size u would have to shave the inside of the gasket everytime u get a bore done or u will have a lip on the inside of it
i would never recommend reusing the same gasket after a bore job to begin with.
No, he is saying that gasket kits only come in the largest overbore size. No company is going to make or stock different head gaskets for different overbores. The exception to this of course is a Big Bore kit.
Either method is fine. The point is to get it very clean. With soap and water you must oil the cylinder immediately to prevent rust. With ATF you are using a high-detergent oil to clean the surface.
dont forget to chamfer the ports in the cylinder walls before reassembly. and clean it, clean it again and after that clean it again. any small piece of metal debris will be certain death for your new sleeve/piston.
.20 of an inch is = to 5.08mm. .020 of and inch is = to .508mm. so .010 is = to .254mm. there is 25.4mm's in an inch.
thanks for the info guys, and yeah, its .020 over but thanks for the correction, will clean it very well b4 putting it back together.,,, thanks again
