Piston skirt question...

Recommended Posts

Hi All. I was reading some of the threads about engine noises and got thinking (yeah-yeah, dangerous I know :worthy: ). Anyway, the short piston skirt seems to be the culprit in several noise cases. So my question is: could a piston with a larger skirt be put in the Z? What would be the benefits? What would be the downsides? If it's strictly a horsepower thing and a piston with a bigger skirt would quiet the motor down, I'd be willing to sacrifice a couple horsepower for it, especially if I was upgrading to a big bore.

What think ye? Discuss 👍

Short answer: No

The DRZ is a short stroke engine. As it is, the piston skirt comes with about 2mm of the crank. Compared to some modern engines, the DRZ skirt is large. A long stroke, slow reving diesel can have a long skit, a Harley can have one.

2 mm? Wow, that is close. Didn't realize it was that tight in there. Thanks.

That's why the DRz is so much more durable engine wise.
