Ok so here goes, I noticed a leak a while back when my dad did a starter rebuild kit after removing the thermostat housing and connecting tubes/pipes. The thermostat pipe(metal) has an O-ring that I ordered from Yamaha that took forever to get here, when it arrived I no longer had a visible leak so I figured I'd let it go for a little bit and replace it the next time I saw the leak. Well other day I did start to see a leak so I went to replace it, when my dad put the bike back together after he did the starter rebuild kit he told me the old bolt to the pipe was stripped and no good he replaced it with some Harbor freight trash and lo and behold it snapped off clean about a 1/4 inch into the hole. I don't have a lot of free time to be messing with things so I got a buddy of mine to drill it out. Well he drilled it out on an angle(left) and too far in(into motor) so i hit it with jb weld on the left side where he poked through bc it was leaking coolant there and it has since stopped but now the issue i am having is coolant now enters the bolt hole for said pipe which i am fairly certain it did not do before. Does anyone know what can be done if anything? I am losing my mind and everyone is playing the blame game and idc i just want to get her back out on the road even if it's not a guarantee that it will fix it. I have been told I need a new motor, been told to cut my losses, been told buddy owes me a new motor and also told it can be welded and frankly I just dont know how to proceed.
