painting those  cheapo shocks will get you on the road but a decent pair of shocks will drastically improve the ride-ability of most bikes.

SICK. But on their site it says not for daily use at all.

You'd need the 8 cell. and they are pretty finicky batteries - I use them

Do/did you need to update or modify your charging system to use the lithium ion batteries?

I bought a new regulator/rectifier from Rick's; using with a ballistic 8 cell. no problems.

No the Lithium batteries have an internal charging management system to ensure they work with the standard bike charging system. Otherwise they could not sell batteries!

You DO need a well functioning charging system. They need slightly more to charge than a lead acid. Most good condition charging systems put out enough though but if it's on the verge maybe not. Shorai has more about this on their site
