Help mounting thick tubing Trek Marlin 29er

Went yesterday and had engine mounted, rode 30 miles home with just the chain popping off once. Today I notice no washers or lock washers on rear stud mounts and the nuts where loose. I tried to add washers then re tighten when a stud tip snapped. The front mount hardware studs are up-sized from stock is there a way to do the same for the rear?
Update: I'm riding in the first lean mix since break in and she started 4 stroking. Went down the line from #70 to settle with #61 which is the smallest I have. She was still 4 stroking and plug check showed too rich. I removed the air-filter and bam like night to day no more 4 stroking. I bought some new plugs b8hs and a 7. I slapped the new 8 in there pre gaped, rode her and she sounded like she was going to 4 stroke for a spit second the stopped. I checked the plug it looks OK to me, how does it look to you all? She seems to run good with my WOT which from the filter side looks like 7/8 OT. I need a different throttle cable it's just rigged for now. She's doing 40 MPH @5500 rpm, what a lucky guess. I bought a fuel filler hose which was the wrong size for this Reed/Carb setup. Anyone know what size this hose should be? I was told 1 in ID and that's way too big.

Went ahead and made a plate with a hack saw and drill, bought some muffler clamps and now all is good. Built my first engine from new parts except carb and did a pressure test and she did 173 psi. I'm using 4 oz per gal Opti oil do I need to add more for break in? I'm just put putting around at idle to almost 1/4 throttle. She needs tuning bad, but later when she's set.
