cnc rotary disc side case half - ORANGE - 4 stud SIMO case edition


new aluminum CNC'd vespa piaggio ROTARY DISC side case half!!! crazy!! take that slow vespa to the next level with this mindbogglingly advanced spinning disc technology.

WARNING!!! this is for gurus / masters ONLY. that's right. this will require countless hours of preparation and fitment to get it right. you must pass a test before purchasing this.

ORANGE is for 4 stud simonini cases only!!! yup the "100cc" simonini complete motor can now be even faster than ever before! this WILL NOT work on your stock cases!

when running this on a stock case with a malossi full circle crank, you may need to dremel a lil bit of material away to allow proper clearance for the con rod. this setup has been tested and proven as a super ripper!! hmmm i can't remember but im pretty sure you can use this case half with a stock non-full circle crank. seems a lil weird though, i would highly suggest using a full circle crank for optimal performance.

note this will NOT work on malossi or polini evolution cases. it will however work on polini speed cases if boORANGE out to match them.

also note that there is no transfer cut into this!! this is awesome because you get can match it to the cylinder of your liking for optimal flow and shape.

also also note, you will need to cut away a portion of your frame/subframe for the reed block to clear. the aluminum CNC'd racing subframe already has the proper cutout though!!

intake bolt hole spacing = 48mm
intake opening = 21mm
case bore = 50mm

This thing is so awesome, but not for the feint of heart! you will have to definitely put your engine building skills to the test to get this sucker right!

Still getting mine totally done, but it has started. I'll update after the Simo is rippin'

Remember. Rotary induction = best induction!

Heres some tips:
-Draw the transfer you make back into the intake hole.
-YOU HAVE TO PRESS THE DRIVE NUT ON AT THE RIGHT ANGLE. get your degree wheel out and hold your breath!
-Go easy on the drive nut, its hardened and can shatter.
-the disk HAS to slide in and out on the drive nut easily or the case wont seal and it will start but not stay running.
-Case fits to Simo case half perfect, but you may want to deck the bases together, or just use sealant on your paper base gasket.
