Ok everyone, I’m about to sound really stupid, but I have two problems.
1) I changed my voltage regulator tonight and took my bike for a ride afterwards and it ran like absolute shit.... it starts backfiring after 2000 rpms. I rode it to my buddies house to use his lift and it ran perfectly fine on the way there.
2) I put my volt meter on the battery after changing the voltage regulator, and while at idle it only shows 12.8 volts and the volts never raise no matter how many rpms you give the bike.
Just noticed you didn't start a new thread.
Well just so we get everyone in on this party here's my message back to the new guy.
When you measured your stator voltage output you measured in AC? Cause it's AC and the VR converts from AC to DC. It should read around 18-20 AC at idle then increase about 2 volts every +1000 RPM.
If that's good, then what about the circuit breaker on bike? The VR goes to a circuit breaker or fuse then to battery for charging. Check that wire voltage directly while bike is running, you didn't hook it straight to the battery did you? Could be a bad fuse or breaker. The OEM breaker you can reset with a little tiny black button it.
Did Curtis send you the compufire VR? Make sure you check your ground wire on that model it's setup different than stock. Stock one was grounded internally compufire you need to have ground bolted in good. I actually run a separate ground wire all the way back to the battery, cause that's a better ground for electrical equipment like a VR that's so important but I'm a little nuts too.
