Merc, the smoke disappears when riding. Reason it was smoking a lot is cause it had been Idling for a while. And we run 25:1 so I can hold WOT for long periods of time, which I do quite often
Our last day in the US will be sad to go will miss it heaps. Have had so much fun!!! Thanks dirty and Harley for letting us stay. Hope fully we will make it back one day!
I know that the Yamaha Fzr 250 will redline around 19000rpm. I don't know if that helps. But it might be interesting to look and see how they get them to run as they do
