Sounds like you need to pull the pump and check the shaft splines. 3 degrees sounds like a lot.
Jetting, help me please...

Sounds like we are getting scammed on bpipes and need to run stock 760 pipes.

I just noticed this comment, but there shouldnt be any issues at all with the engine. The entire bottom end has about 20 hours on it tops, everything was brand new, top end was just done, all new gaskets, o rings, etc. Before install the motor was leaktested to 11psi. The stator resistances were all check while moving the wires, the coil resistances were checked doing the same. ndd i just got brand new vforce 3 reeds, carbs were rebuilt last sept with all new n/s, gaskets, etc. Right now im at 115, 132.5 and Im gonna try to get that tuned.... once I replace my driveshaft, midshaft, and bendix in hopes to get rid of these terrifying rattles.
I also cant believe how much black sludge ive created in such a short time, the whole exhaust was literally coated in like 2mm of sludge. Could my gas-oil ratio to be too low? Im running 40:1 because I heard it helped with breaking in the motor... should I be running 50:1?

40-1 should be fine. If you need a new drive shaft hit me up.

I tested the coil and it matched the specs consistently while moving the wires around. Still think it could be a coil?

When you said you are running blowsion raincoats, are you talking about the pre-filter? If so try taking them off, had a friend who had kinda the same problem.

I took them off yesterday when someone else suggested it. Still no luck. I'm about to order parts and I don't wanna have to order a $1000 of parts lol.

Well i ordered a new Yamasaki coil and bendix from JetManiac and Im setting my timing back to stock from the current 2 degree advance. Hopefully these changes solve my rattling and my idle issues. Contemplating picking up a set of blackjacks and getting rid of these damn OEM 44's.

I agree, I just feel like theres something Im missing in my carbs (possibly). Like maybe a port or circuit is clogged or something. Or maybe I am just completely retarded and cant tune carbs at all. But the way its acting makes no sense to me, one minute its acting like its starving for fuel cause i need to use primer to get it to start, the next its flooding and caking my exhaust in black sludge, the next it wont fire at all, then all of a sudden a certain rpm will run smooth, change that rpm by like 100rpm and it shakes so violently i wouldnt be surprised If i broke something already.

Just tested all the values I could on my stator. Got 2.5volts on the pulse coil, 35volts on the charge coil. Didn't bother checking the lighting coil. Resistances all seemed within Yamaha specs. So out of curiosity I've read the pulse coil should be 4-5volts, is this true? Is my issue a bad pulse coil?

Run the ski long enough for things to heat up and try it again. Mine would run perfect for about 5-10min then the rev limiter would drop to 5k.
