40 with no washers is correct. You should check the videos of the Colortune, if you haven't seen it before. I thought they had gone out of production, but they can be had online from the UK for around $60-70, well worth it IMHO. Thanks for the heads-up on the Casoli!

I'm having more electrical issues!! Went to fire it up, it started the first time, but bogged down a bit. Went about tuning the mix/idle speed screw (which killed the engine a few times) Went to start it again, in successive attempts the fuse blew! I swapped it out for another ceramic 15A, but no luck. I'm hoping the solenoid/CDI/rectifier isn't damaged. The ceramic fuses I've got are quick-blow, so fingers crossed that it's just another bad fuse. I've got to be patient when starting this bike after it dies, as it seems too many attempts puts a draw on the system and blows fuses.

Ran out of daylight, so it looks like more troubleshooting on my plate tomorrow, yum.
