Operator needs intel!!!

Recommended Posts

Same old issue: intermittent drop out on tip in or full load

Bike: 2007 dr650 18,500 miles

95% stock, garage kept, driven daily, street queen

new battery, manual fuel valve, bypassed side-stand switch

carb clean, new plugs, great spark

Runs fine at idle, hot and cold. Choke working as designed.

Either I have a fuel starvation issue (lean back fire at times)

or....an electrical issue (causing ignition loss/break down and fuel load-up)

Today I removed all fairing/panels, seat and fuel tank. Inspected all wiring and connections (all looked good) and made 100% that there was not any wiring binding or rubbing.

I also installed a vacuum hose extension to a carb cleaner can to the vacuum port to the old stock fuel valve connection. Secured the carb cam to the handlebars so I could supplement fuel temporarily when the issue occurs to rule out a lean condition.

Test drove bike and now the problem is gone. ***?! :bonk:

Installed logic probe, tapped into trigger side of coil and never saw a drop out.

Any suggestions?? What gives the trigger signal to the CDI unit? Please help...:smirk:
