PS...Welcome, Edwin.

Hope you enjoy your ride here.


Only as a suggestion, create a signature

code letters.

You can add that bike photo to the signature too.


And also as a suggestion , make your next new post over in the new member welcome area to say hello.

It's not seeing the CSP. Engine does not know were pistons are to set timing. Won't fire plugs like that.

Will it crank? (turn over from starter motor)

Need to know if is carburetor or FI.

Read this.. may eliminate us a lot of texting and then get back here and let me know what you think?

Does your bike have a security system? It sounds like a TSSM (turn signal / security module) problem.

Not an expert here. Probably either the 15A ignition or battery fuse. Or ignition switch or 30 amp circuit breaker. Is your check for power now.
