Stroker Crank for air cooled?

[wilmar13]

A search came up empty for stroker crank options for our engine... no one has gone that route yet to get more grunt from the air cooled 1000/1100 engine?

I've heard it can be done but its costly. Don't know of anyone who has done it to the Hyper.

The Ducshop could help you with that if you need.

As far as I know "big bore" is the only way for now, 100mm bore will get you 1123cc, a 102mm is also available, but requires case boring, crank rebalancing, & steel liners installed in the cylinders. (a lot of work) Aloha Alex
