Maybe the highest hp 650 Super moto bikes around?

Little known fact?- Factory Pro has built quite a few national race winning racebikes.
We are specialists in custom and production tuning.

Factory Pro produces many private labeled products for aftermarket and oem companies - carb kits, ignition products, engine covers, etc....

To extract the maximum power for the engine, it is necessary to use the Low Inertia EC997 Eddy Current Dynamometer with 4 Gas to concurrently dial in the carbs and the cam timing. You can't really do optimum work on an inertia dyno, as is usually found at dealerships levels -

Carb Recalibration Kit



1. Choose your shipping method


Initial power improvements are aprox. 4 True HP when using Factory Pro's patented HDJ Carb kit as measured under load and not in a misleading sweep test.

If you get all the rpm and throttle positions *right* for best power, then when you ride and *do* sweep through all those throttle positions and rpms, it *will* be right for Best Power - under all conditions -
That's how we consistently can design products that outperform products developed on dj dynos and their clones.

Better and smoother throttle control - better fuel mileage - down EIGHT sizes in the main jet - More power - Better "feel".

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
