More xr350 parts on my hawk.

The TachoAdapt thing was a Nogo. Not sure if the unit was damaged by my cdi but it failed to work. I wound up connecing the blue and white tach wire from the cluster to a charging leg, pre regulator, through a diode. Bingo tach is working..

Bummer is its reading x2, not sure what i can do about that, unless the cluster has a cyl count setting or the like.

The Xl500s engine is a beast, and Ive gotten used to the difference in gravity center.

Im still struggling with a rich burble just off idle, jetting in either direction with main or idle has no effect and needle position is not having an effect.

Im going to try a different slide next, I believe its a number 1. The mikuni im using was off a snowmobile and seems to just tip in really rich. she idles perfect. Revs right up, but stumbles with a blast of black smoke on tip in once warmed up.

Im still not forced to use the choke often so maybey a bit leaner on the idle jet, but im not sure..

The xl500s used a Keihin with 155 main and 35 idle..

I found a chart that shows 155 = 132.5 in mikuni but had to guess on the idle.
