Makes sense lol, yeah I live in piedras negras, but i work and was born and raised in eagle pass,I am running a V-2 I got last year, you only have to make sure to flip the bottom end upside down and shake out any possible metal fillings still in it, pour a little gas/oil mix into that bottom end and swirl it around a bit and pour it out just to make sure there is no more filings in it,
Check for any inside the cylinder casting flashings that need to be filed off and smoothed out so it does not catch the rings.
From there, just take some 2 cycle oil and rub it around inside the cylinder and on the piston rings and put things together.
I'm a moderator of the forum, It's my business to know to eliminate spammers and scammers who try to get into forums like ours...lol.
So I don’t have to change the wrist pin or piston , read that the v2 had a lot of issues with ring snag
