I ordered one of those for my VM26, but I am still waiting for it's arrival. I can definitely let you know for sure once it comes in.

Good discussion though because I want to get this right.

Well, the nice thing about sprockets is, they aren't overly expensive or difficult to change, especially going down in tooth count. Just try to figure out what gear ratio is ideal for your bike, you (weight etc), and it's use. For road use, I would try to gear it so that the revs in 5th gear sit right around where torque peak is at whatever MPH you want it to cruise at. This may make the bike over geared as far as top speed, and kill a bit of the acceleration, but I would rather not sit at redline to go 60mph. Plus, generally an engine is it's most efficient around it's peak torque RPM, because that is the point where VE and Intake velocity are at their highest, usually giving the most clean burn.

I think the 46 rear is a good starting point for what you want. It will put you right at 3.07. Then, if you want to go a little taller, try a 16 front, shorter then your 14 front. Going in either direction wouldn't require changing the chain links either as it's only a +1 or -1 front. That would give you a 2.88 and a 3.29 respectively. That's why I suggested the rear first.
