so I finally checked my needle, which is the stock needle the bike came with. It's an "OBD". I discovered it has 7 clip positions. I dropped the needle one clip yesterday
all I can say is TAFFY is DA man! Leaner is better
My jetting experiences with this 06 Fe550e are:
I am a C rider, mostly ride woods trails. I ride 4000 Ft elevation, 40F-60F winter, 60F-90F summer temps. The bike gearing is one tooth down on the CS from stock. I rarely see 4th gear, never see 5th or 6th. My trails speeds are 0- 40 mph max. Mostly I run 0-25mph on single tracks, 10- 35 mph on open trails. I do run the rpms out on each gear, but my throttle is only 0- 50% open, maybe 5/8ths open, rarely 3/4, never full open.
Last year, I was running year round the settings MotoXotica gave me.
45 Pj
1.5 turns FS
185 Mj
OBD 5th clip down from top.
Bike ran and started good, but a little buttery through the range.
discovered mo power on a 35F degree day so then I went to a 175 Mj
Bike ran crisper, but when summer temps of 70F plus came, it was buttery again with less power.
soon went to a 170mj and it ran little better, but buttery again at 80F temps
so Yesterday I dropped the clip one and that was magic. bike is crisp again. I am now at
45 Pj
1.5 turns FS
170 Mj
OBD clip at the middle slot 4 from top and 4th from bottom.
4000ft and 70-80F temps
Like Taffy and others have said, inch by inch I go leaner and its gets better each time. I did notice it was a little tricky to start yesterday cold, but maybe thats becuase I was in the carb, just before I ran it. once It ran, it started good all day. One thing about these bergs, Buttery rich is less power. Leaner and crisp = Bike has better lifting front end power. by comparison, My Husky actually felt mo power when it got a little buttery.
Thanks Dale, Taffy and all others for jetting advice.
