87 or 91 Octane?

And we don't have nothing close to 12-1 compression either, Thats a large part of why the Nomad engines are so conservately powered for their size.

Any brand recondition?

Compression ration doesn't make as much difference as you might think it would. May be 2% per point? There are other factors like how well the heads flow, RPM capability and what RPM it makes power, which is controlled by the cam.

I havn't used a octane booster product in many years now, but the one I did use was called 104 Octane Boost. Im not even sure if it exists any more. But Im sure there is some product available.
Any car or bike performance shop should carry it.

Im aware of that, but thats part of the package required to get some power out of these motors. Larger valves and ports, higher lift cam, larger FI unit and it will wake up. But its probably not worth the investment on these motors for what youll gain.

That aftermarket doesn't exist for kawasaki. HD for sure. Some bikes you get that from the get go.

Thunder Mfg and Muzzy have big bore kits available for the Vulcans they are about $1500.00 and require the heads to be ported as well as the FI body.

But that's it. In fact, I am not sure Muzzy does it anymore. Still, what is to be gained? It's still a open loop system with stock cams. Ok. 80HP at the rear wheel? May be 85? What's the longevity after that? I am not sure. If there was a better aftermarket or really demand I suppose, we'd see a lot more results and therefore would have a better idea.

I suppose if someone is buying a vtwin cruiser, they aren't looking for a sport bike or a bike with a lot of power to begin with. It is what it is. Might as well save some money and buy a C14 as a second bike. ;)

Id love a second bike with some power in it, but our insurance rates here are stupidly high and most can't afford more than one bike. Although my brother is toying with the idea of possibly getting an older Hyabusa for those days when you want to wring something out. He just got his K1200RS out today for its first ride.

May be he can give you the beemer if he gets the hyabusa.

With a country of such a low population in proportion to it's size, it's difficult to understand why the rates are so high. Mine was around 400 for the year.

I take the Beemer out once in a while to get my frustrations out. it a nice quick handling bike with a bit of zip in it.

Always ran 91 oct gas but after reading the posts on this thread I tried 3 tanks of 89 oct gas and the bike ran good no pinging but I thought bike had a little more zip with the 91 oct gas so went back to the 91 oct gas. the MPG stayed the same.
