Well, to start I’m flowing almost as much fuel through it as it can physically flow. I have run it without rear jets and it is just slightly fat. I have had to open up the accelerator pump nozzle to help with the lean spike at the hit. The air door spring is fragile because if you tighten it more than 1– 1 1/2 turns it breaks and the part is not available separately. With full spring tension I’m still slamming the air door open so fast it spikes lean. I have fitted an air horn for it that is good for 5-10 hp, but can’t use it because it makes the air door open even quicker. I have timed how fast the door opens. About 1/10 sec from start to full open. I’m required to run an AVS, but that is why mine is way out of it’s comfort zone. I have thought of running Q16, but I don’t think the 800 can physically flow 25% more fuel than what I’m currently running.
