My brother in law is having trouble with his 07 700. Hits 70kmh in high and low. Hits 110 on jack stands so CVT is not the issue. Not developing enough power to get top speed while driving.

He replaced the piston and rings over the winter but I don’t think that is the issue. Has a brand new correct spark plug which still looks fine. No smoke from the exhaust amd no gas in the oil. No obstruction in the intake. Injector test produces the 5 clicks it’s supposed to. Fuel pump pickup sock is clean. Runs fine at idle and low speed but will not develop enough power to hit the top end. Hits the gumband in low, does not cut out or miss in high, just runs out of steam. He had cleaned the injector with carb cleaner when he had the motor pulled apart. Anyone run into something like this before? I’m thinking either fuel pump or injector. Local shop is trying to get him to do a leak down test but there’s no way that worn rings would be costing this much power and not smoking.
