I think he has air/ fuel ratio confused with compression ratio, both need to be lowered. And how does fuel pressue change fuel mixtue on a carb motor ?

Did u upgrade the motor mounts? Someone told me Baja lags into the stringers instead of using the offshore type. Like I said, that's what I heard

BTW, congrats on the power increase. I'm thinking about doing the same to my 500's if I keep my boat. 3 blowers

I talked with the motor guy again. He said he told me that the AF was 1 point off when he checks it with a O2 sensor. So he said i will have to take 1 point off the totals. He also said that he was gonna re jet the carb.

The carb has 90,s front and back. he said that he was putting 93,s in the front and 95,s in the back.

my 93 outlaw is just lagged. i did not switch to offshore mounts but i installed metal plates across the stringers to help distribute the weight. then re-alined the engine. it is that same baja style.... cheap and quick. might be my last baja

What size & brand carb are you working with ?

1050 dominator

You may be able to reduce high speed air bleed size so you won,t have to run such a big main jet, big jets will foul plugs in lower RPM range.

I would put the power valves back in the carbs & run 86-88 jets. Big carb with rich jets = ring & bearing failure.

Exactly, unless it was loosing or had low fuel pressure at higher rpms, it doesn't do anything to richen it.
