At ET-Performance, we have raced nearly all brands of motorcycles, mostly in the dirt, since 1971. It is only natural that the unique properties of the KrankVent have been applied to all brands of cycles with the same great results.

This may sound strange to a super bike rider where the engine pulses are much smoother than on the V-Twin. However, the ability to produce a crank case vacuum and the resulting benefits has been observed numerous times.

The only current restriction is that the engine must be a four stroke.

Large displacement, singles and twins really come alive with the KrankVent!! However, all four strokers will benefit, particularly with improved ring seal, and a smoother, more efficient running engine. We are now testing the KrankVent on some strong 4-cylinder race engines: a 1200 cc Yamaha and a 750 cc GSXR. We will keep you informed of the results.

Because there are so many different engines it would be hard to cover them all here. Basically, the metric KrankVent kit is what we use for all metric engines.  The Japanese and other engines are well constructed so that they remain airtight and can maintain the vacuum produced.
