So, honed and installed pistons w/Wiseco kit. Now, how the hell do I get at the bottom jug bolts to torque them down? I have a 1/2" drive torque wrench and am thinking of welding a socket to a 9/16" box wrench.

I once helped a friend do a top end on this motor. I just took a 14mm box wrench, and cranked them down till good and tight. Imo, if you've tightened enough bolts in the day you get the feel when enough is enough torque.

I have done the same,tighten with wrench best you can. I also use blue loctite just for insurance, so the nuts do not come loose. I have seen a 500 on the side of the trail with a loose jug.

same, just did mine by feel. I think they're 30ft/lb? snug it up nice. a small 14mm box wrench will need some good tug on it to get to that ft/lb

Yeah, 30-34 ft lbs. I've never needed loctite on these nuts, but probably couldn't hurt.

torque adapter wrench. they make short boxed end wrenches for this. seeing this also holds the crank case together and crush fit is very important. this is one area that guessing is not going to work well for longevity.

Thanks all! I have a 9/16” crows foot adapter and the correct torque conversion with the added length. The heads suggest Loctite 242 so I am going to use this on the base as well.

Probably too late but don't forget to torque the head to the cylinders before you torque the cylinders to the crankcase on this engine.

i would put the y pipe on the cylinders somewhat loose, then do the head, then take off y pipe, then do the cylinders, lines everything up nicely
