Hi everyone, purchased a non running basket case 2000 800xl. Complete rebuild, top to bottom. New crankshaft pistons, Nikasil and carb rebuilds with genuine Mikuni kits. Starts good, idles good but won't accelerate. Seems to bog out. If I give it a shot of primer it accelerates as it should. Above 4500 rpm it runs flawlessly. I just cant get it above 4500 without giving it a shot of gas with primer. Tried opening up low speed jets numerous times with no success. It seems like it's not getting fuel in the low speed circuit, yet idles fine. Looking for ideas. Thx
