Seen it? i've done it! kind of.
took off my tool box cover (OK OK! it fell off...) and used zip ties and electrical tape to mount the cdi suggly in there.
doesn't look nice cause i am lazy and don't have the finesse to make it look pretty.
i got my breather filter at autozone for about $7. i picked up two small hose clamps and a little hose adapter they had there for a few bucks each and it worked out really well, or has so far.
As for moving the battery, I haven't gotten that far yet. again, too lazy. BurnPGH has his bungee-corded into the frame resting at the back of the cradle resting on something or another.
