HPI CDI mini rotor ignition system for yamaha RD250, DS7, RD350, YR5, RD400


new HPI CDI mini rotor ignition for yamaha RD250 (1973-1979), YDS7 (DS7), RD350 (1973-1975), YR5 (1985-1991), RD400 (1976-1980)

this version has an integrated 60W light coil for super bright lights!! great curve and comes with all you need to make the change. plus you can adjust your stator anytime even with the flywheel mounted!

uses a 27mm x 1mm left hand thread puller!!!!!

always use a resistor boot or resistor plug when running a cdi or you run the risk of burning up your cdi box!

the trail tech voltage regulator works the best with the mini rotor!

ooh and it has timing marks on it now whoooieeeee

the stator may be black, red or gold, whichever color HPI sends out. its not something we can choose, so its not something you can choose either.

I love how simple it was to install this system to my bike. You did not need any crazy tools to install it.  You will need to get a shorter 7mm bolt for the flywheel.

To verify your timing, you will need a dial indicator and timing light. Set your timing for 1.8mm btdc (19 degrees) and it should advance your timing to about 2.8mm btdc (24 degrees).

How to install it on your RD350: http://www.2strokeworld.net/forum/index.php?topic=1139.msg20142#new
