WB1 wont rev turned full lock

[88kawi5fiddy]

IDK i have a theory, but anyone else had this happen?

new b1 i put together and rode today runs frikkin great. a little weird jetting off idle, but not every launch.

now: during hard turns after WOT straight, turn bars, pin it, motor bogs and wont really climb RPM. turn bars straight, instantly revs out.

is my nozzle eclipsing the reduction and just straight up cant push water?

82mm (i think) 62t reduction, trim ring and whatever stock plastic nozzle is on it. I swear ive read this happening to someone before but cant find it.

I remember two threads, here they are.

Here's one.

Blaster cutting out when leaning left

As above. Had this issue for sometime but trying to get to the bottom of it. 701 with B pipe and twin 44's 44's have full rebuild, 2mm needle and seats, 120 pilot and 120 main with pop off of 30psi. Ski runs great on tick over all the way up to WOT. Issue is when I go to side mount from the left...

Here's the other.

Turning the bars puts in limp mode lol

Sounds crazy right... but that's what I got on this 96 blaster I just picked up... Fine if the bars are straight it has its normal power then as soon as you turn the bars it just chops it and puts it in a limp mode rev limiter. Doesn't matter if you're WOT and turn them or doing donuts holding...

Is it still running the original crank? My 97 GP 760 does this because the crank bearings are fried. You can't move the crank inside the bearings by hand but both G force in hard turns and the power stroke are enough to push the crank out of true inside the bearings opening up an air gap between the crank and seals. It causes a very lean condition by drafting in quite a lot of air from the crank seal leak drying out your base and giving you the "bog" effect. A quick check you can do to test if your bearings are worn is if the coupler off the crank is getting hot. I actually burnt my finger on the GP coupler it was so hot. The bearings are so badly worn it's creating a lot of friction inside the races. My SuperJet goes through far more abuse than the GP and I can get my hand on the coupler right after stopping for a break without concern.

Aha! I have a trim nozzle setup and stock pump exit exhaust. I can almosy guarantee that its pushing too much water into the exhaust
