As I obsess over this new project CR515AF supermoto bike, im constantly looking for ways to make it easier to hang with the sport bikes I usually ride with at the events I go to. ::up::
A hand full of years ago I bought a 01 CR250 ignition with all parts, but come to find out it wasn't a 01 like he said, its a 92-96 CR250 ignition. What I'm thinking is, obviously it has to have a different ignition curve than the stock 1991 CR500R ::rollieyes::
I also have a 00 CR250R that I built for woods years ago and rarely ride I could borrow the ignition system off of just to see how it differs.

Im just some teenager with very little knowledge on such topic, but I would love some advice on ignition systems and how they affect the power band On these big bore 2 strokes. Any pointers or advice from the experienced would be really appreciated ::up::

Update: The 92-96 CR250 CDI box is a direct plug in fit to my CR500's ignition. Same connectors and same style box. Idk exactly what the differences are but here are the numbers of each cdi box.

Current (assumed stock) cr500 cdi: 070000-1862
1992-1995 or 1996 CR250 CDI: 070000-2480

The bike is jetted for 110 octane so I'm sure there is plenty of safe space to experiment with small timing changes
