ok well, i got a small crack thats a big problem.
history. low side cracked engine cover on the left side and a dented radiator on the right side. i got the new cover and out it on, it leaked (but hardly any) and so i drained it, and put it back on cleaning it even more this time and using more of the RVT silicon gasket maker that was reccomended to me. i started it up and let it un for a bit and all was going well burned off all the oil on the headers so no more smoke. then we noticed a leak, very small like the first time right under the cover at the bottom bolt. looking at it we noticed that the bolt went though to the other side ( all the way though the engine cover, then into the block and out the other side), so you can see the tip of the bolt from the back. so we thought maube it leaking thought there, (even though we put gasket maker all around the edge of the block ( P.S. first time we put gasket maker on the cover, second time we put gasket maker on the block) . so we took that bolt out and filled it up with gasket maker and put the bolt back in. Not long after it was still leaking.
so from there we knew that wasnt the problem since even though it didnt have time for the gasket maker to cure it still would have stopped the leak or at least slowed it a bit. so we were lookin around and most of the block is pretty smooth, and we noticed this one little what looked like a scratch in the metal. sure enough thats there the leak is coming from.
i think its a crack in the block very small maybe a centemeter long and a hair thick. but it has droplets of oil on it. its definatly that, i still have to take the cover back off and check from the inside so see what it looks like from there.
My question is: what can i do to fix this? would JB Weld work, id have to put it on the inside and if i do since there is oil in there would it flake off and get into other parts of the engine, would the magnetic field be disrupted by it, can i even put it there? can i put it on the outside too, or do i have to buy another block.
also we had it running and it got to over 200degrees and the fan didnt come on, Problem? i think so, i have no idea where the thermostat is on this bike and maybe its electrical who knows, what temp does the fan normally kick in on?
any suggestions are greatly apperiated and if you live close by to northern VA i could use all the help i can get. thanks
