I'd love to hear how this works out for you. I really would prefer using the front sprocket if it lubes well without any extra mess.I put I think the final draft version of the nozzle on yesterday;
I'll refine the hose clamp situation after shaking it down for a while. Definitely a solid mount and easy enough to tweak the nozzle so drips are about equal on both sides of the chain. About 1/4" clearance between the tips of the nozzles and the chain at maximum whip, but arranged in this way the chain will push it up out of the way if there is interaction.
