Very Rough Idle, and a bit of 'Pain' driving on the Street, as it had to maintain
1600 RPM's just to stay running, or it would load-up.

Had 'Hardened Pushrods' and 'stock' Stamped Steel Rockers.

After one-month, replaced the 'stock' rocker components with a set of Rocker-Rollers
{Adjustable} with Aluminum Rocker Shaft.

Like 'Night-and-Day' difference. Idled better, and pulled the Rev's up quicker.

The Demon is a 'Rocket'
