Truble the 15" screen was also my first choice, but after some research on the findings of other riders I bought the 19" and I'm glad I did. I drove about 60 miles yesterday at different speeds with the windshield on and I must say that there is a bit
protection but not so much as I wish for. I my opinion is the 15" a total waste of the money, the only part that is a bit protected to the elements with the 19" ,is the upper body but the face but the face gets the full blow of the wind and the choice
f helmet is critical to get a good result. Would I buy it again, yes.. because it took some of the wind from my body and is a bit more comfortable to drive at higher speeds. But the ultimate "high speed" cruiser is the other white one you see on the
picture btw I'm 1m76 tall and I do not now what that is in feet

 

Try adding one of these little MRA vario spoilers to the top of the windscreen:

Verio Spoiler

They have about 7 positions that you can try to eliminate the last of the buffeting which will depend on your height and riding position.

 

Thanks for the tip, I take a look at your link.

 

 

 

Nice numbers! Must be fun to ride.

But, some questions.....you have the Stage IV kit, so IIRC it's now a 117" motor with the CNC ported heads and presumably a bigger throttle body? Does your bike have the Power or Torque cam - or is it a totally different cam for the Stage IV kit?

I have only the Stage 2 (torque) cam, Bassani RR3 exhaust and Heavy Breather AC on my 114" bike and I get the same 126 ft lbs TQ, but my peak torque is at 3.6K RPM vs your at 4.5k RPM. You do get 14 more HP at the top end though :-) And it looks like from about 4K RPM your HP curve is higher than mine.

So my conclusion here is that the Stage IV kit properly tuned will walk away from my Stage II bike after 4K RPM, but up until then I will probably be faster.

Very interesting. My dyno chart is below for comparison.....

 

 

:-) Sounds just like me. Another inveterate tinkerer. I want to do a 124" kit and a non HD cam once my warranty is up. Only 11 months to go. It's getting towards winter here now and I will have a tough time not pulling it apart over the winter.

The guy that tuned my bike told me that there was still a lot of discussion about the flow characteristics on the CNC ported heads and whether they were much better than the stock ones for most uses. Apparently the stock ones flow plenty air anyway - however the CNC ported ones will have better velocity at high flow rates due to different throat castings. Not sure how much is rumour, hearsay or truth, but I am waiting for my favourite head porter to tool up for M8 heads. Hopefully that will happen about the same time as the warranty expires.
