Just to make some noise----
"Best" is such a fun word.
Really all depends on what ya figger on doing with yer bike for the 'best' main.
When I was getting into terrorizing the 1800 riders (oh, and about anyone else I could torment), with the mods I had on my bike, the FP225 was the best jet.
Then I did a rather long trip thru the mountains. That 'best' jet really suuuuucked. It was sad. Really sad. Couple of the Ohio guys got to take a look at what was left of the sooted, shrapnelled remains of my baffles after that trip. And it sounded funny, too.
Did a FP200 on another mountainous sojourn. Bike was absolutely fantastic in the mountains. That was the 'best' for that higher altitude riding. Of course when I came back to flatland and didn't change the jetting for a few weeks the local guys took advantage of suddenly being able to whup my posteranious. They gloated plenty. I did get even.
Then I did finally settle down and went with a FP 215. That was the 'best' for the way my bike was set up for general go anywhere, do anything riding. Altitude, rodding around, jist a cruisin'.
It's entirely possible to tune yerself into the 'best' limited situation. Then there's the rest of the time yer ridin'.
Just thought I'd mention it all.
