EXPANSION CHAMBER VISUALLY EXPLAINED Posted by: DIOSpeedDemon
Video duration: 449 seconds I am continually trying to get the perfect version of how an expansion chamber piper works. I may make a few of these little videos until I get the right one. This one looks rough and I may not keep it up on the youtube. I hate to practice or prepare for a video too much, because it ruins the spontaineity. I need to find just the right words to explain this expansion chamber effect.RH Related: 50, aerox, apriilia, dio, elite, honda, jog, porting, race, scooter, stroke, stroker, tuning, two, vision, yamaha |

MONSTER 50MM STROKER CRANK DIO CASE Posted by: DIOSpeedDemon
Video duration: 160 seconds THis is one way of aligning the crank to work in the stock case. I used a dremel to widen the crank bore. This engine has AF26 stamped on the transmission cover. I believe that is the European designation of this motor. A special bore tool is available to do this job, though I do not have one or seen one.

CYLINDER SQUISH BAND CLEARANCE CHECK Posted by: DIOSpeedDemon
Video duration: 414 seconds A proper squish clearance can give your motor 10% more power. Most aftermarket cylinder kits are not made to this close tolerance of 0.6-0.8mm proper piston clearance. We check the squish band clearance and usually have to close the gap from .18 -.13mm down to .8mm gap for proper squish band function to work properly.

FINAL FITTING OF 52.5 X 54 MM ENGINE ASSEMBLY Posted by: DIOSpeedDemon
Video duration: 599 seconds This dry run has produced a couple of unseen problems that I did not intend. Big Rod End is slightly rubbing and crank galley has to be slightly re-worked. I am running out of useable aluminum to mate the cases for an air tight fit. Every thing is going remarkably well so far. If this motor fires up, it will be Damn Loud. THe Louder, THe Ruder, the BETTER. Sorry about the cussing. RH Related: 50, aerox, apriilia, dio, elite, honda, jog, porting, race, scooter, stroke, stroker, tuning, two, vision, yamaha |
