ground strap

[branson]

Is there a factory ground from the engine to the frame or is it just the bole running through the bottom of the block? My frame is painted so it makes a crappy ground. Anybody added a ground and if so where? Pics? Trying to find an easy/quick/cheap electrical boost to my bike for better spark.

A frame ground won't help with a better spark. The sparkpkugs ground to the engine!

Adding another ground wire to the frame is a trivial matter. Just go from the battery negative to somewhere convenient on the frame. a 12G wire should be more than enough. You will have to make sure the connector or bolt touches bare metal.

gotcha ill be disconnecting and sanding that spot on my frame soon and rechecking that wire. i was concerned that not having a good connection between the engine and the frame would hinder spark plug performance. new plugs will be installed again soon as well. anything better than the plain ol boring stock kind? i wish there was something like bosche platinum plus 4's for bikes.
