Yes Juergen your rigth, not rum for youse org. intake,when you youse 4TW radiator, that too wide , this is the only way make this, and ist Ok i belive.
The left Airbox with std. frame (no Hole ) ist wath you kan make it, from right side as i have.
But 5Ke and 4TW air ,is kompl.diff.
Mine Airbox is homemade for this bike,only top is from 5KE, this is big big job.
Rui or me will bring you result for Test how many HP i bring on RW. Waith for better wether over here. And bring you more pic.
Hemi. Sorry Bad Englich.
