I cannot get my 1997 Honda CR500 mx'r to start.
- Background: Low hours bike, no mods/rebuilds, all equip is original. Sits for months at a time. Ran fine last time ~ 6 months ago.
- Here's what I've done:
1. Fresh gas, new plug
2. Dissembled, inspected and cleaned the carb. No problems found, no varnish build up.
3. Verified spark by grounding on top of cylinder head. Spark is yellow/blue in color.
4. Verified ohm resistance on electrical components per Honda Service Manual. All ck'd OK.
5. Ck'd electrical connectors. All OK.
6. Ck'd reeds for any damage. All OK
Symptoms. Bike has good compression, and appears to be getting fuel from the smell of gas on the plug when I remove it. It will momentarily fire usually one time when I first start kicking it over. Then nothing each kick after. Seems to make no difference whether chock is on or off. I suspect the Ignition Control Module (ICM) may be faulty with respect to the ignition timing. But there is no way to verify this module other than to replace it ($200!).
Please help
