DROWsports Grand Axis Two Stroke Powered Ruckus


The exotic JDM Windjammer expansion chamber is all stainless with a carbon silencer and costs a ton.  Since the expansion chamber makes so much power on a two stroke it is worth it!  DROWsports also sells cheaper chambers for the Grand Axis engine if you want to do a swap like this.
A big Stage 6 28mm flat slide carburetor is used.  This is nearly twice the size of the stock carb.  A Stage 6 carbon V-Power reed block is used.  This has more than twice the reed valve area of the stock reed valve.  This is topped by Stage 6 intake manifold.  This manifold has a straight shot into the crankcase unlike the twisting turning stock manifold.  It does require some frame modifications to do it but since the Ruckus is an engine swap, the motor mounts were designed to stay out of the way.
The 120/80-12 Dunlop tire was replaced with a lower profile and lighter Maxxis 130/70-12 tire which resulted in better acceleration.
The assembled engine was mounted to the Ruckus chassis with a DROWsports motor mount kit.  The Ruckus frame was shaved of all unused brackets and had the mounts tig welded in place.  Here you go, more than quadruple the stock power!
You can see the DROWsports starter delete plate and delrin frame sliders protecting the super expensive Windjammer pipe!  Normally a Stage 6 foam air filter is run but it was removed for pictures.
The bike was fitted with DROWsports carbon bars and gooseneck.  A CRG mirror is used with OEM Yamaha controls.
